| 3 | A statistical analysis of mesoscale eddies in the Bay of Bengal from 22–year altimetry data显示文摘Eddy properties in the Bay of Bengal are studied from 22 a archiving, validation and interpretation of satellite oceanographic(AVISO) data using a sea level anomaly(SLA)-based eddy identification. A geographical distribution and an eddy polarity, an eddy lifetime and propagation distances, eddy origins and terminations,eddy propagation directions and trajectories, eddy kinetic properties, the evolution of eddy properties,seasonal and interannual variabilities of eddy activities are analyzed in this area. Eddies exist principally in the western Bay of Bengal and most of them propagate westward. The polarity distribution of eddies shows cyclones prefer to occur in the northwest and south of the Bay of Bengal, while anticyclones mainly occur in the east of the bay. Five hundred and sixty-five cyclones and 389 anticyclones with the lifetime that exceeds 30 d are detected during the 22 a period, and there is a preference for the cyclones for all lifetime and propagation distances. The kinetic properties of all observed eddies show the average amplitude of the cyclones is larger than that of the anticyclones, whereas that is opposite for average radius, and their average velocities are basically the same. Moreover, the evolution of eddies properties reveals that the eddies with a long lifetime that exceeds 90 d have a significant double-stage feature of the former 50 d growth period and the dying period after 50 d. For the seasonal variability of the eddies, the cyclones occur more often in spring while the anticyclones occur more often in summer. The analysis of long-lived eddy seasonal distributions shows that there is the obvious seasonal variation of the eddy activities in the Bay of Bengal. The interannual variability of an eddy number shows an obvious negative correlation with the EKE variation. | CUI Wei YANG Jungang MA Yi | 2016 | Acta Oceanologica Sinica2016，35，11： | 13 |
| 4 | Graphitic carbon nitride (g-C3N4)-based nanosized heteroarrays: Promising materials for photoelectrochemical water splitting显示文摘Photoelectrochemical(PEC)water splitting is recognized as a sustainable strategy for hydrogen generation due to its abundant hydrogen source,utilization of inexhaustible solar energy,high-purity product,and environment-friendly process.To actualize a practical PEC water splitting,it is paramount to develop efficient,stable,safe,and low-cost photoelectrode materials.Recently,graphitic carbon nitride(g-C3N4)has aroused a great interest in the new generation photoelectrode materials because of its unique features,such as suitable band structure for water splitting,a certain range of visible light absorption,nontoxicity,and good stability.Some inherent defects of g-C3N4,however,seriously impair further improvement on PEC performance,including low electronic conductivity,high recombination rate of photogenerated charges,and limited visible light absorption at long wavelength range.Construction of g-C3N4-based nanosized heteroarrays as photoelectrodes has been regarded as a promising strategy to circumvent these inherent limitations and achieve the high-performance PEC water splitting due to the accelerated exciton separation and the reduced combination of photogenerated electrons/holes.Herein,we summarize in detail the latest progress of g-C3N4-based nanosized heteroarrays in PEC water-splitting photoelectrodes.Firstly,the unique advantages of this type of photoelectrodes,including the highly ordered nanoarray architectures and the heterojunctions,are highlighted.Then,different g-C3N4-based nanosized heteroarrays are comprehensively discussed,in terms of their fabrication methods,PEC capacities,and mechanisms,etc.To conclude,the key challenges and possible solutions for future development on g-C3N4-based nanosized heteroarray photoelectrodes are discussed. | Liqun Wang Wenping Si Yueyu Tong Feng Hou Daniele Pergolesi Jungang Hou Thomas Lippert Shi Xue Dou Ji Liang | 2020 | Carbon Energy2020，2，2： | 10 |
| 5 | The Electric Field Detector (EFD) onboard the ZH-1 satellite and firstobservational results显示文摘Previous studies have reported that, before or after occurrences of strong earthquakes, some low earth orbit satellites recorded ionospheric disturbances, including electromagnetic emissions and plasma fluctuations over the epicenter region or its conjugate point.Theoretically speaking, due to some electromagnetic coupling effect, electromagnetic emissions from the earthquake preparation zone could propagate from the lithosphere to the atmosphere, and could reach the ionosphere, even up to the inner magnetosphere. This paper introduces the electric field detector(EFD) onboard the ZhangHeng-1 satellite(ZH-1). The EFD is designed to measure electric field fluctuations within the broad frequency range of DC to 3.5 MHz, divided into 4 channels: ULF(DC–16 Hz), ELF(6 Hz–2.2 kHz), VLF(1.8 kHz–20 kHz) and HF(18 kHz–3.5 MHz). The sampling rates of the channels are 125 Hz, 5 kHz, 50 kHz and 10 MHz, respectively. The EFD includes4 spherical probes mounted on a over 4.5 m boom and an electronic box inside the satellite module. The resolution of the EFD is 1μV·m-1·Hz-1/2 at frequencies from DC to 16 Hz, and the sensitivity is 0.1 μV·m-1·Hz-1/2 at frequencies from 6 Hz to 2.2 kHz, 0.05 μV·m-1·Hz-1/2 in the band 1.8 kHz to 20 kHz, and 0.1μV·m-1·Hz-1/2 from 20 kHz to 3.5 MHz. The dynamic range from DC to 20 kHz is over 120 dB, and over96 dB from 20 kHz to 3.5 MHz. The EFD has two observation modes: survey mode and burst mode. The survey mode concentrates primarily on electric field power density values; the burst mode provides high sampling rate waveform data. The detailed configuration of the EFD onboard the ZH-1 is also introduced in this paper. During the six months' orbit test phase, the EFD recorded a number of natural electromagnetic emissions. Preliminary analysis of these data suggests that the EFD performs well onboard the ZH-1 and is meeting the requirements of the scientific objectives of ZH-1. | JianPing Huang JunGang Lei ShiXun Li ZhiMa Zeren Cheng Li XingHong Zhu WeiHao Yu | 2018 | Earth and Planetary Physics2018，2，6： | 8 |
| 6 | The Influence of Extractable Organic Matter on Pore Development in the Late Triassic Chang 7 Lacustrine Shales, Yanchang Formation, Ordos Basin, China显示文摘To investigate the influence of extractable organic matter(EOM) on pore evolution of lacustrine shales, Soxhlet extraction, using dichloromethane, was performed on a series of Chang 7 shale samples(Ordos Basin, China) with vitrinite reflectance of 0.64% to 1.34%. Low-pressure gas adsorption experiments were conducted on the samples before and after extraction. The pore structure parameters were calculated from the gas adsorption data. The results show complex changes to the pore volumes and surface areas after extraction. The pore development of both the initial and extracted samples is strongly controlled by total organic carbon(TOC) content. Micropores developed mainly in organic matter(OM), while mesopores and macropores predominantly developed in fractions other than OM. The influence of EOM on micropores is stronger than on mesopores and macropores. Organic solvents with a higher boiling point should be used to explore the effect of EOM on pore structure in the future. | HAN Hui LIU Pengwei DING Zhengang SHI Pitong JIA Jianchao ZHANG Wei LIU Yan CHEN Shijia LU Jungang Chen Kang PENG Xudong WANG Zhiyong XIAO Shuqi GAO Yuans | 2018 | Acta Geologica Sinica(English Edition)2018，92，4： | 8 |
| 7 | The validation of HY-2 altimeter measurements of a significant wave height based on buoy data显示文摘HY-2 has been launched by China on August 16,2011 which assembles multi-microwave remote sensing payloads in a body and has the ability of monitoring ocean dynamic environments.The HY-2 satellite data need to be calibrated and validated before being put into use.Based on the in-situ buoys from the National Data Buoy Center(NDBC),Ku-band significant wave heights(SWH,hs)of HY-2 altimeter are validated.Eleven months of HY-2 altimeter Level 2 products data are chose from October 1,2011 to August 29,2012.Using NDBC 60 buoys yield 902 collocations for HY-2 by adopting collocation criteria of 30 min for temporal window and 50 km for a spatial window.An overall RMS difference of the SWH between HY-2 and buoy data is 0.297 m.A correlation coefficient between these is 0.964.An ordinary least squares(OLS)regression is performed with the buoy data as an independent variable and the altimeter data as a dependent variable.The regression equation of hs is hs(HY-2)=0.891×hs(NDBC)+0.022.In addition,2016 collocations are matched with temporal window of 30 min at the crossing points of HY-2 and Jason-2 orbits.RMS difference of Ku-band SWH between the two data sets is 0.452 m. | WANG Jichao ZHANG Jie YANG Jungang | 2013 | Acta Oceanologica Sinica2013，32，11： | 7 |
| 8 | Influence of physiological and environmental factors on the diurnal variation in emissions of biogenic volatile compounds from Pinus tabuliformis显示文摘Biological volatile organic compounds(BVOCs) have a large influence on atmospheric environmental quality, climate change and the carbon cycle. This study assesses the composition and diurnal variation in emission rates of BVOCs from Pinus tabuliformis, using an enclosure technique. Environmental parameters(temperature and light intensity) and physiological parameters(net photosynthetic rate, P_n; stomatal conductance, g_s; intercellular CO_2 concentration, C_i; and transpiration rate, T_r) that may affect emission behavior were continuously monitored. The 10 most abundant compound groups emitted by P. tabuliformis were classified by gas chromatography–mass spectrometry. The dominant monoterpenoid compounds emitted were α-pinene, β-myrcene, α-farnesene and limonene. The diurnal emission rate of BVOCs changed with temperature and light intensity, with dynamic analysis of BVOCs emissions revealing that their emission rates were more affected by temperature than light. The variation in monoterpene emission rates was consistent with estimates of P_n, g_s and T_r. Basal emission rates(at 30 °C,) of the main BVOCs ranged from 0.006 to 0.273 μg^(-1)/(hr g),while the basal ER standardization coefficients ranged from 0.049 to 0.144 °C^(-1). Overall, these results provide a detailed reference for the effective selection and configuration of tree species to effectively prevent and control atmospheric pollution. | Jungang Chen Huaxing Bi Xinxiao Yu Yanlin Fu Wenchao Liao | 2019 | Journal of Environmental Sciences2019，31，7： | 7 |
| 9 | Generation and manipulation of chiral terahertz waves in the three-dimensional topological insulator Bi2Te3显示文摘Arbitrary manipulation of broadband terahertz waves with flexible polarization shaping at the source has great potential in expanding numerous applications,such as imaging,information encryption,and all-optical coherent control of terahertz nonlinear phenomena.Topological insulators featuring unique spinmomentum-locked surface state have already exhibited very promising prospects in terahertz emission,detection,and modulation,which may lay a foundation for future on-chip topological insulator-based terahertz systems.However,polarization-shaped terahertz emitters based on topological insulators with an arbitrarily manipulated temporal evolution of the amplitude and the electric-field vector direction have not yet been explored.We systematically investigated the terahertz radiation from topological insulator Bi2Te3 nanofilms driven by femtosecond laser pulses and successfully realized the generation of efficient chiral terahertz waves with controllable chirality,ellipticity,and principal axis.The convenient engineering of the chiral terahertz waves was interpreted by a photogalvanic effect(PGE)-induced photocurrent,while the linearly polarized terahertz waves originated from linear PGE-induced shift currents.Our work not only provides further understanding of femtosecond coherent control of ultrafast spin currents but also describes an effective way to generate spin-polarized terahertz waves at the source. | Haihui Zhao Xinhou Chen Chen Ouyang Hangtian Wang Deyin Kong Peidi Yang Baolong Zhang Chun Wang Gaoshuai Wei Tianxiao Nie Weisheng Zhao Jungang Miao Yutong Li Li Wang Xiaojun Wu | 2020 | Advanced Photonics2020，2，6： | 6 |
| 10 | Three-dimensional conformal intensity-modulated radiation therapy of left femur foci does not damage the sciatic nerve显示文摘During radiotherapy to kill femoral hydatid tapeworms,the sciatic nerve surrounding the focus can be easily damaged by the treatment.Thus,it is very important to evaluate the effects of radiotherapy on the surrounding nervous tissue.In the present study,we used three-dimensional,conformal,intensity-modulated radiation therapy to treat bilateral femoral hydatid disease in Meriones meridiani.The focus of the hydatid disease on the left femur was subjected to radiotherapy(40 Gy) for 14 days,and the right femur received sham irradiation.Hematoxylin-eosin staining,electron microscopy,and terminal deoxynucleotidyl transferase-d UTP nick end labeling assays on the left femurs showed that the left sciatic nerve cell structure was normal,with no obvious apoptosis after radiation.Trypan blue staining demonstrated that the overall protoscolex structure in bone parasitized with Echinococcus granulosus disappeared in the left femur of the animals after treatment.The mortality of the protoscolex was higher in the left side than in the right side.The succinate dehydrogenase activity in the protoscolex in bone parasitized with Echinococcus granulosus was lower in the left femur than in the right femur.These results suggest that three-dimensional conformal intensity-modulated radiation therapy achieves good therapeutic effects on the secondary bone in hydatid disease in Meriones meridiani without damaging the morphology or function of the sciatic nerve. | Wanlong Xu Xibin Zhao Qing Wang Jungang Sun Jiangbo Xu Wenzheng Zhou Hao Wang Shigui Yan Hong Yuan | 2014 | Neural Regeneration Research2014，9，20： | 6 |
| 11 | Underwater topography detection of Shuangzi Reefs with SAR images acquired in different time显示文摘Imaging mechanism of underwater topography by SAR and a underwater topography SAR detection model built on the theory of underwater topography detection with SAR image presented by Yuan Yeli are used to detect the underwater topography of Shuangzi Reefs in the Nansha Islands with three scenes of SAR images acquired in different time. Detection results of three SAR images are compared with the chart topography and the detection errors are analyzed. Underwater topography detection experiments of Shuangzi Reefs show that the detection model is practicable. The detection results indicate that SAR images acquired in different time also can be used to detect the underwater topography, and the detection results are affected by the ocean conditions in the SAR acquiring time. | YANG Jungang ZHANG Jie MENG Junmin | 2007 | Acta Oceanologica Sinica2007，26，1： | 6 |
| 12 | A Polysaccharide-Degrading Marine Bacterium Flammeovirga sp.MY04 and Its Extracellular Agarase System显示文摘Bacteria of the genus Flammeovirga can digest complex polysaccharides (CPs), but no details have been reported regarding the CP depolymerases of these bacteria. MY04, an agarolytic marine bacterium isolated from coastal sediments, has been identified as a new member of the genus Flammeovirga. The MY04 strain is able to utilize multiple CPs as a sole carbon source and grows well on agarose, mannan, or xylan. This strain produces high concentrations of extracellular proteins (490 mg L-1 ± 18.2 mg L-1 liquid culture) that exhibit efficient and extensive degradation activities on various polysaccharides, especially agarose. These proteins have an activity of 310 U mg-1 ± 9.6 U mg-1 proteins. The extracellular agarase system (EAS) in the crude extracellular enzymes contains at least four agarose depolymerases, which are with molecular masses of approximately 30-70 kDa. The EAS is stable at a wide range of pH values (6.0-11.0), temperatures (0-50℃), and sodium chloride (NaCl) concentrations (0- 0.9 mol L-1). Two major degradation products generated from agarose by the EAS are identified to be neoagarotetraose and neoagarohexaose, suggesting that β-agarases are the major constituents of the MY04 EAS. These results suggest that the Flammeovirga strain MY04 and its polysac-charide-degradation system hold great promise in industrial applications. | HAN Wenjun GU Jingyan YAN Qiujie LI Jungang WU Zhihong GU Qianqun LI Yuezhong | 2012 | Journal of Ocean University of China2012，11，3： | 5 |
| 13 | Primary investigation of the pollution status of polycyclic aromatic hydrocarbons (PAHs) in water and soil of Xuanwei and Fuyuan,Yunnan Province,China显示文摘Lung cancer incidence in Xuanwei and Fuyuan is extremely high. The air pollution, especially indoor airborne PAHs generated by burning smoky coals, has been considered as the most probable reason. The air pollution may affect drinking water and soil through dry and wet deposition. In this study, the concentrations of PAHs in water and soil samples from Xuanwei and Fuyuan were monitored to investigate the influence of atmospheric PAHs pollution on water and soil. No obvious PAHs pollution in water was found in these two areas, indicating that airborne PAHs have no apparent effect on the drinking water (well water). The smoky coal combustion from household and industry, such as the activities related to power plants, coking plants and chemical industries, is responsible for the soil PAHs pollution in these two areas. The soil pollution might be the reemission source and would pose long-term threat to the local environment and health of residents. | LU JunGang XU RenJi ZHANG QingHua LIU JiYan LIAO ChunYang WEI FuSheng | 2009 | Chinese Science Bulletin2009，54，19： | 4 |
| 14 | The enhanced corrosion resistance of UMAO coatings on Mg by silane treatment显示文摘The surface silanization was carried out on ultrasonic micro-arc oxidation(UMAO) coatings on pure magnesium using KH550 as silane coupling agent(SCA). The surface morphology, chemical bonds and corrosion resistance of the silane films were investigated by scanning electron microscope(SEM), Fourier transform infrared spectroscopy(FTIR) and electrochemical workstation, respectively. The results showed that hybrid coatings were successfully prepared on pure magnesium by UMAO-Na OH(1 mol/L, 2 mol/L, 3 mol/L)-SCA processing. The organic films with Si–O–Mg bonds are helpful for the reduction of the pores in UMAO coatings. The pores decreased with increasing Na OH concentration. Compared with single UMAO treatment, the corrosion potentials(Ecorr) of magnesium plates with UMAO-Na OH(1 mol/L,2 mol/L, 3 mol/L)-SCA treatment increased by 29 m V, 53 m V and 75 m V, respectively, meanwhile the corrosion current density(Icorr) reduced one to two orders of magnitude. It indicated that the corrosion resistance of the coatings was improved by silane treatment. | Muqin Li Jiang Liu Jungang Li Yongjiang Li Shouduo Lu Yuqi Yuan | 2014 | Progress in Natural Science:Materials International2014，24，5： | 4 |
| 15 | Data-Driven Heuristic Assisted Memetic Algorithm for Efficient Inter-Satellite Link Scheduling in the BeiDou Navigation Satellite System显示文摘Inter-satellite link(ISL)scheduling is required by the BeiDou Navigation Satellite System(BDS)to guarantee the system ranging and communication performance.In the BDS,a great number of ISL scheduling instances must be addressed every day,which will certainly spend a lot of time via normal metaheuristics and hardly meet the quick-response requirements that often occur in real-world applications.To address the dual requirements of normal and quick-response ISL schedulings,a data-driven heuristic assisted memetic algorithm(DHMA)is proposed in this paper,which includes a high-performance memetic algorithm(MA)and a data-driven heuristic.In normal situations,the high-performance MA that hybridizes parallelism,competition,and evolution strategies is performed for high-quality ISL scheduling solutions over time.When in quick-response situations,the data-driven heuristic is performed to quickly schedule high-probability ISLs according to a prediction model,which is trained from the high-quality MA solutions.The main idea of the DHMA is to address normal and quick-response schedulings separately,while high-quality normal scheduling data are trained for quick-response use.In addition,this paper also presents an easy-to-understand ISL scheduling model and its NP-completeness.A seven-day experimental study with 10080 one-minute ISL scheduling instances shows the efficient performance of the DHMA in addressing the ISL scheduling in normal(in 84 hours)and quick-response(in 0.62 hour)situations,which can well meet the dual scheduling requirements in real-world BDS applications. | Yonghao Du Ling Wang Lining Xing Jungang Yan Mengsi Cai | 2021 | IEEE/CAA Journal of Automatica Sinica2021，8，11： | 4 |
| 16 | Primary Analysis of Oceanic Mesoscale Eddies Observation Abilities by Sentinel-3A SRAL显示文摘In this study,the north-western Pacific Ocean of Kuroshio region is selected as the experimental area to analyze the mesoscale eddies observation abilities of Sentinel-3 A SRAL,including the independent detection abilities of Sentinel-3 A SRAL and the improvement of mesoscale eddies detection abilities by data fusion with other satellite altimetry data.The Sentinel-3 A SRAL data are mapped by the spatial-temporal objective analysis method to the sea level anomaly grid data.The mapping errors are analyzed by the comparisons between the grid data of different combinations and along the ground track of Jason-2/3.The independent detection abilities of Sentinel-3 A SRAL are analyzed by the comparison between the grid data and the AVISO MSLA data.On the other hand,through the multi-satellite data fusion of different combinations of Sentinel-3 A altimeter and other satellite altimeters such as Jason-2/3,the mesoscale eddies detection was performed based on the merged sea level anomaly data and the addition of Sentinel-3 A SRAL data for the improvements of mesoscale eddies detection abilities by multi-satellite altimeters are concluded.It is concluded that Sentinel-3 A SRAL has good abilities of mesoscale eddies detection as the combination of Jason-2 and Jason-3,and it is better than that of single altimeter of Jason-2 or Jason-3. | Jungang YANG Jie ZHANG Wei CUI Munoz MAITE Makhoul EDUARD | 2021 | Journal of Geodesy and Geoinformation Science2021，4，1： | 3 |
| 17 | Retrograde embolization technique of the right gastric artery during the implantation of port-catheter system for hepatic arterial infusion chemotherapy显示文摘Objective:This study aimed to introduce and evaluate a new embolization technique for the right gastric artery(RGA) during percutaneous implantation of a port-catheter system for hepatic arterial infusion chemotherapy(HAIC).Methods:From January 2013 to January 2017,159 patients with unresectable advanced liver cancer underwent percutaneous implantation of a port-catheter system.In 86 of these patients(56 men;aged 28-88 years;mean:60.6±12.0 years),in whom the RGA was obvious on arteriography,embolization of RGA was attempted using microcoils to protect the gastric mucosa during HAIC.In the first phase(first three years),antegrade embolization of the RGA using a 2.7 Fr microcatheter was performed in 55 patients.In the second phase(next two years),embolization of the RGA was attempted by combining antegrade embolization and retrograde embolization through the left gastric artery(LGA) in 31 patients.The success rates and the incidence of acute gastroduodenal mucosal toxicity(AGMT) in these two groups were compared.Results:The total success rate of the RGA embolization was 70.9%.The success rate was 83.9% in 31 patients who underwent combined antegrade and retrograde embolization,which was significantly higher than that of antegrade embolization alone(63.6%) performed in 55 patients(p=0.047).No complications related to embolization of RGA were documented.The incidence of AGMT was 29.1%(16/55) in patients in the first phase,which was significantly higher than that in the patients in the second phase(9.7%,3/31)(p=0.037).Conclusion: A combination of retrograde embolization via LGA could increase the success rates of RGA embolization and reduce the incidence of AGMT after HAIC. | Jungang Hu Guang Cao b Liang Xu Kanglian Zheng Xu Zhu Renjie Yang Xiao Wang Xiaodong Wang | 2021 | Journal of Interventional Medicine2021，4，1： | 3 |
| 18 | MORPHOLOGY AND ELEMENTAL COMPOSITION OF DUSTFALL PARTICLES INSIDE EMPEROR QIN'S TERRA-COTTA WARRIORS AND HORSES MUSEUM显示文摘Indoor dustfall samples were collected in Pit 1 and Pit 2 of Emperor Qin’s Terra-cotta Warriors and Horses Museum in Xi’an, Shaanxi Province, China. The morphological and elemental analysis for long-term (>10 years) and short-term (~0.5 year) dustfall particles and lacquer pieces on the faces of partly assembled warriors were performed with scanning electron microscopy with energy dispersive X-ray spectrometer (SEM/EDX). The results showed that the ma-jority of dustfall samples appeared to be composed of mineral dust particles, fly ash, and biological particles with different elemental compositions. Most of the mineral particles had irregular shapes with smooth edges. Small floccules of calcium sulfate were more frequently observed in long-term dustfall samples than in short-term samples, implying a progressive chemical reaction between continuous dustfall particles and atmospheric sulfur dioxide. Crystals of calcium sulfate were also found near pits on both inner and outer surfaces of lacquer pieces, revealing an acid chemical reaction between sulfur dioxide and lacquer material as the cause of the formation of erosion pits and cracks on surface of lacquer pieces. | Tafeng Hu Xuxiang Li Jungang Dong Bo Rong Zhenxing Shen Junji Cao Shun-Cheng Lee Judith C.

| 19 | Cross-calibration on the electromagnetic field detection payloads of the China Seismo-Electromagnetic Satellite显示文摘The China Seismo-Electromagnetic Satellite(CSES)deploys three payloads to detect the electromagnetic environment in the ionosphere.The tri-axial fluxgate magnetometers(FGM),as part of the high precision magnetometer(HPM),measures the Earth magnetic vector field in a frequency range from direct current(DC)to 15 Hz.The tri-axial search coil magnetometer(SCM)detects the alternating current(AC)related magnetic field in a frequency range from several Hz to 20 k Hz,and the electric field detector(EFD)measures the spatial electric field in a broad frequency band from DC to 3.5 MHz.This work mainly crosscalibrates the consistency of these three payloads in their overlapped detection frequency range and firstly evaluates CSES’s timing system and the sampling time differences between EFD and SCM.A sampling time synchronization method for EFD and SCM waveform data is put forward.The consistency between FGM and SCM in the ultra-low-frequency(ULF)range is validated by using the magnetic torque(MT)signal as a reference.A natural quasiperiodic electromagnetic wave event verifies SCM and EFD’s consistency in extremely low-frequency and very low-frequency(ELF/VLF)bands.This cross-calibration work is helpful to upgrade the data quality of CSES and brings valuable insights to similar electromagnetic detection solutions by low earth orbit satellites. | ZHIMA Zeren ZHOU Bin ZHAO ShuFan WANG Qiao HUANG JianPing ZENG Li LEI JunGang CHEN Yu LI Cheng YANG DeHe SUN XiaoYing MIAO YuanQing ZHU XingHong SHEN XuHui | 2022 | Science China(Technological Sciences)2022，65，6： | 3 |
| 20 | A detection model of underwater topography with a series of SAR images acquired at different time显示文摘underwater topography is one of oceanic features detected by Synthetic Aperture Radar.Underwater topography SAR imaging mechanism shows that tidal current is the important factor for underwater topography SAR imaging.Thus under the same wind field condition,SAR images for the same area acquired at different time include different information of the underwater topography.To utilize synchronously SAR images acquired at different time for the underwater topography SAR detection and improve the precision of detection,based on the detection model of underwater topography with single SAR image and the periodicity of tidal current,a detection model of underwater topography with a series of SAR images acquired at different time is developed by combing with tide and tidal current numerical simulation.To testify the feasibility of the presented model,Taiwan Shoal located at the south outlet of Taiwan Strait is selected as study area and three SAR images are used in the underwater topography detection.The detection results are compared with the field observation data of water depth carried out by R/V Dongfanghong 2,and the errors of the detection are compared with those of the single SAR image.All comparisons show that the detection model presented in the paper improves the precision of underwater topography SAR detection,and the presented model is feasible. | YANG Jungang ZHANG Jie MENG Junmin | 2010 | Acta Oceanologica Sinica2010，29，4： | 3 |
