| 1 | Modeling study of regional severe hazes over mid-eastern China in January 2013 and its implications on pollution prevention and control显示文摘The Nested Air Quality Prediction Model System(NAQPMS)was used to investigate the temporal and spatial variations of PM2.5over tropospheric central eastern China in January 2013.The impact of regional transport and its implications on pollution prevention and control were also examined.Comparison between simulated and observed PM2.5showed NAQPMS was able to reproduce the evolution of PM2.5during heavy haze episodes.The results indicated that regional transport of PM2.5played an important role in regional haze episodes in the city cluster including Hebei,Beijing and Tianjin(HBT).The cross-city clusters transport outside HBT and transport among cities inside HBT contributed 20%–35%and 26%–35%of PM2.5as compared with local emission,in HBT respectively.To meet the Air Quality Standards for Grade II,90%,90%and65%of emissions would have to be cut down in Hebei,Tianjin and Beijing,if non-control strategy was taken in the surrounding city clusters of HBT.This implicated that control of emissions in one city cluster is not sufficient to reduce regional haze events,and joint efforts among city clusters are essential.Besides regional transports,two-way feedback between boundary-layer evolution and PM2.5also significantly contributed to the formation of heavy hazes,which contributed 30%of monthly average PM2.5concentration in HBT. | WANG ZiFa LI Jie WANG Zhe YANG WenYi TANG Xiao GE BaoZhu YAN PinZhong ZHU LiLi CHEN XueShun CHEN HuanSheng WAND Wei LI JianJun LIU Bing WANG XiaoYan WAND Wei ZHAO YiLin LU Ning SU DeBin | 2014 | Science China Earth Sciences2014,57,1: | 106 |

| 3 | Multiple-aged granitoids and related tungsten-tin mineralization in the Nanling Range, South China显示文摘The Nanling metallogenic belt in South China is characterized by well-developed tungsten-tin mineralization related to multiple-aged granitoids.This belt is one of the 5 key prospecting and exploration areas among the 19 important metallogenic targets in China.Important progress has been made in recent years in understanding the Nanling granitoids and associated mineralization,and this paper introduces the latest major findings as follows:(1)there exists a series of Caledonian,Indosinian,and Yanshanian W-Sn-bearing granites;(2)the Sn-bearing Yanshanian granites in the Nanling Range form an NE-SW trending aluminous A-type granite belt that stretches over 350 km.The granites typically belong to the magnetite series,and dioritic micro-granular enclaves with mingling features are very common;(3)the Early Yanshanian Sn-and W-bearing granites possess different petrological and geochemical features to each other:most Sn-bearing granites are metaluminous to weakly peraluminous biotite(hornblende)granites,with zircon Hf(t)values of ca.2 to 8,whereas most W-bearing granites are peraluminous two-mica granites or muscovite granites with Hf(t)values of ca.8 to 12;(4)based on the petrology and geochemistry of the W-Sn-bearing granites,mineralogical studies have shown that common minerals such as titanite,magnetite,and biotite may be used as indicators for discriminating the mineralizing potential of the Sn-bearing granites.Similarly,W-bearing minerals such as wolframite may indicate the mineralizing potential of the W-bearing granites.Future studies should be focused on examining the internal relationships between the multiple-aged granites in composite bodies,the metallogenic peculiarities of multiple-aged W-Sn-bearing granites,the links between melt evolution and highly evolved ore-bearing felsic dykes,and the connections between granite domes and mineralization. | CHEN Jun WANG RuCheng ZHU JinChu LU JianJun MA DongSheng | 2013 | Science China Earth Sciences2013,56,12: | 46 |
| 4 | Transplantation of UC-MSCs on collagen scaffold activates follicles in dormant ovaries of POF patients with long history of infertility显示文摘Premature ovarian failure(POF) is a refractory disease for clinical treatment with the goal of restoring fertility. In this study,umbilical cord mesenchymal stem cells on a collagen scaffold(collagen/UC-MSCs) can activate primordial follicles in vitro via phosphorylation of FOXO3 a and FOXO1. Transplantation of collagen/UC-MSCs to the ovaries of POF patients rescued overall ovarian function, evidenced by elevated estradiol concentrations, improved follicular development, and increased number of antral follicles. Successful clinical pregnancy was achieved in women with POF after transplantation of collagen/UC-MSCs or UC-MSCs. In summary, collagen/UC-MSC transplantation may provide an effective treatment for POF. | Lijun Ding Guijun Yan Bin Wang Lu Xu Yan Gu Tong Ru Xiaoying Cui Lei Lei Jingyu Liu Xiaoqiang Sheng Bin Wang Chunxue Zhang Yanjun Yang Ruiwei Jiang Jianjun Zhou Na Kong Feifei Lu Huaijun Zhou Yannan Zhao Bing Chen Yali Hu Jianwu Dai Haixiang Sun | 2018 | Science China(Life Sciences)2018,61,12: | 43 |
| 5 | Effects of field application of phosphate fertilizers on the availability and uptake of lead, zinc and cadmium by cabbage (Brassica chinensis L.) in a mining tailing contaminated soil显示文摘A field trial was conducted to evaluate the reduction of bioavailability of heavy metals including lead (Pb), zinc (Zn) and cadmium (Cd) in a soil contaminated by mining tailings in Shaoxing, Zhejiang, China. Three commercial phosphate (P) fertilizers including phosphate rock (PR), calcium magnesium phosphate (CMP), and single superphosphate (SSP) were applied to the plot at three P application rates, 50, 300, and 500 g/m2 with 9 treatments and control (CK). Plants, water soluble and exchangeable (WE) extraction procedure and modified toxicity characteristic leaching procedure (TCLP) were employed. It was found that the addition of all three P fertilizers significantly decreased WE Pb (22.0%-81.4%), Cd (1.5%-30.7%) and Zn (11.7%-75.3%, exception of SSP treatments with no significant difference) and TCLP Pb concentration (27.1%-71.2%), compared with the control, leading to reduced uptake of Pb (16.0%-58.0%), Cd (16.5%-66.9%) and Zn (1.2%-73.2%) by cabbage (Brassica chinensis L.). It was suggested that P fertilizers induced immobilization of heavy metals such as Pb, Cd, and Zn. CMP provided the most effective method of reducing metal toxicity, mobility, and phytoavailability. At the P application rate of 300 g/m2, CMP would be cost-effective to decrease WE Pb, Zn, and Cd concentration from 666 to 137 mg/kg, from 31.2 to 8.71 mg/kg, and from 1.69 to 1.36 mg/kg, respectively. SSP was more effective in reducing Pb bioavailability than PR but had variable effects on Zn bioavailability. Cd uptake by cabbage was negatively correlated with soil pH rather than with WE or TCLP, indicating that Cd uptake by cabbage was a complex process. It should be careful to evaluate the impact of phosphate application on Cd availability in soil. | Biling WANG Qiufeng SU | 2008 | Journal of Environmental Sciences2008,20,9: | 39 |
| 6 | Chinese deserts and sand fields in Last Glacial Maximum and Holocene Optimum显示文摘The Last Glacial Maximum (LGM, c. 26-16 ka) and the Holocene Optimum (HO, c. 9-5 ka) were characterized by cold-dry and warm-wet climates respectively in the recently geological Earth. How Chinese deserts and sand fields responded to these distinctive climatic changes is still not clear, however. To reconstruct environments of the deserts and sand fields during the LGM and HO is helpful to understand the forcing mechanisms of environment change in this arid region, and to test paleoclimatic modeling results. Through our long-term field and laboratory investigations, 400 optically stimulated luminescence (OSL) ages and more than 100 depositional records in the Chinese deserts and sand fields were obtained; on the basis of these data, we reconstruct spatial distributions of the deserts and sand fields during the LGM and HO. Our results show that the sand fields of Mu Us, Hunshandake, Horqin and Hulun Buir in northern and northeastern China had expanded 25%, 37%, 38% and 270%, respectively, during the LGM; the sand fields of Gonghe in the northeastern Qinghai-Tibetan Plateau had expanded 20%, and the deserts of Badain Jaran, Tengger in central northern China had expanded 39% and 29% separately during the LGM; the deserts of Taklimakan, Gurbantünggüt and Kumtag in northwestern China had expanded 10%-20% respectively, compared to their modern areas. On the other hand, all of the sand fields were nearly completely covered by vegetation during the HO; the deserts in northwestern and central northern China were reduced by around 5%-20% in area during this time. Lakes in this arid region were probably expanded during the HO but this conclusion needs more investigation. Compared with the geological distributions of deserts and sand fields, human activity has clearly changed (expanded) the area of active sand dunes at the present time. Our observations show that environmental conditions of Chinese deserts and sand fields are controlled by regional climate together with human activity. | LU HuaYu YI ShuangWen XU ZhiWei ZHOU YaLi ZENG Lin ZHU FangYing FENG Han DONG LiNa ZHUO HaiXin YU KaiFeng MASON Joseph WANG XiaoYong CHEN YingYong LU Qi WU Bo DONG ZhiBao QU JianJun WANG XunMing GUO ZhengTang | 2013 | Chinese Science Bulletin2013,58,23: | 40 |
| 7 | Aerosol and boundary-layer interactions and impact on air quality显示文摘Air quality is concerned with pollutants in both the gas phase and solid or liquid phases. The latter are referred to as aerosols, which are multifaceted agents affecting air quality, weather and climate through many mechanisms. Unlike gas pollutants, aerosols interact strongly with meteorological variables with the strongest interactions taking place in the planetary boundary layer(PBL). The PBL hosting the bulk of aerosols in the lower atmosphere is affected by aerosol radiative effects. Both aerosol scattering and absorption reduce the amount of solar radiation reaching the ground and thus reduce the sensible heat fluxes that drive the diurnal evolution of the PBL. Moreover, aerosols can increase atmospheric stability by inducing a temperature inversion as a result of both scattering and absorption of solar radiation, which suppresses dispersion of pollutants and leads to further increases in aerosol concentration in the lower PBL.Such positive feedback is especially strong during severe pollution events. Knowledge of the PBL is thus crucial for understanding the interactions between air pollution and meteorology. A key question is how the diurnal evolution of the PBL interacts with aerosols, especially in vertical directions, and affects air quality.We review the major advances in aerosol measurements, PBL processes and their interactions with each other through complex feedback mechanisms, and highlight the priorities for future studies. | Zhanqing Li Jianping Guo Aijun Ding Hong Liao Jianjun Liu Yele Sun Tijian Wang Huiwen Xue Hongsheng Zhang Bin Zhu | 2017 | National Science Review2017,4,6: | 37 |
| 8 | Molecular subtyping and genomic profiling expand precision medicine in refractory metastatic triple-negative breast cancer:the FUTURE trial显示文摘Triple-negative breast cancer(TNBC)is a highly heterogeneous disease,and molecular subtyping may result in improved diagnostic precision and targeted therapies.Our previous study classified TNBCs into four subtypes with putative therapeutic targets.Here,we conducted the FUTURE trial(ClinicalTrials.gov identifer:NCT03805399),a phaseⅠb/Ⅱsubtyping-based and genomic biomarker-guided umbrella trial,to evaluate the efficacy of these targets.Patients with refractory metastatic TNBC were enrolled and stratifed by TNBC subtypes and genomic biomarkers,and assigned to one of these seven arms:(A)pyrotinib with capecitabine,(B)androgen receptor inhibitor with CDK4/6 inhibitor,(C)anti PD-1 with nab-paclitaxel,(D)PARP inhibitor included,(E)and(F)anti-VEGFR included,or(G)mTOR inhibitor with nab paclitaxel.The primary end point was the objective response rate(ORR).We enrolled 69 refractory metastatic TNBC patients with a median of three previous lines of therapy(range,1-8).Objective response was achieved in 20(29.0%,95%confidence interval(CI):18.7%-41.2%)of the 69 intention-to-treat(ITT)patients.Our results showed that immunotherapy(arm C),in particular,achieved the highest ORR(52.6%,95%CI:28.9%-75.6%)in the ITT population.Arm E demonstrated favorable ORR(26.1%,95%C:10.2%-48.4%in the ITT population)but with more high grade(23)adverse events.Somatic mutations of TOP2A and CD8 immunohistochemical score may have the potential to predict immunotherapy response in the immunomodulatory subtype of TNBC.In conclusion,the phaseⅠb/ⅡFUTURE trial suggested a new concept for TNBC treatment,demonstrating the clinical beneft of subtyping-based targeted therapy for refractory metastatic TNBC. | Yi-Zhou Jiang Yin Liu Yi Xiao Xin Hu Lin Jiang Wen-ia Zuo Ding Ma Jiahan Ding Xiaoyu Zhu Jianjun Zou Claire Verschraegen Daniel G.Stover Virginia Kaklamani Zhong-Hua Wang Zhi-Ming Shao | 2021 | Cell Research2021,31,2: | 37 |
| 9 | Overexpression of the maize GRF10, an endogenous truncated growth-regulating factor protein, leads to reduction in leaf size and plant height显示文摘It has long been thought that growth‐regulating factors(GRFs) gene family members act as transcriptional activators to play important roles in multiple plant developmental processes. However, the recent characterization of Arabidopsis GRF7 showed that it functions as a transcriptional repressor of osmotic stress‐responsive genes. This highlights the complex and diverse mechanisms by which different GRF members use to take action. In this study, the maize(Zea mays L.) GRF10 was functionally characterized to improve this concept. The deduced ZmGRF10 protein retains the N‐terminal QLQ and WRC domains, the characteristic regions as protein‐interacting and DNA‐binding domains, respectively. However,it lacks nearly the entire C‐terminal domain, the regions executing transactivation activity. Consistently, ZmGRF10 protein maintains the ability to interact with GRF‐interacting factors(GIFs) proteins, but lacks transactivation activity.Overexpression of ZmGRF10 in maize led to a reduction in leaf size and plant height through decreasing cell proliferation,whereas the yield‐related traits were not affected. Transcriptome analysis revealed that multiple biological pathways were affected by ZmGRF10 overexpression, including a few transcriptional regulatory genes, which have been demonstrated to have important roles in controlling plant growth and development. We propose that ZmGRF10 aids in fine‐tuning the homeostasis of the GRF‐GIF complex in the regulation of cell proliferation. | Lei Wu Dengfeng Zhang Ming Xue Jianjun Qian Yan He Shoucai Wang | 2014 | Journal of Integrative Plant Biology2014,56,11: | 31 |
| 10 | Short-chain fatty acids act as antiinflammatory mediators by regulating prostaglandin E_2 and cytokines显示文摘AIM:To investigate the effect of short-chain fatty ac-ids (SCFAs) on production of prostaglandin E2 (PGE2),cytokines and chemokines in human monocytes.METHODS:Human neutrophils and monocytes were isolated from human whole blood by using 1-Step Polymorph and RosetteSep Human Monocyte Enrich-ment Cocktail,respectively. Human GPR41 and GPR43 mRNA expression was examined by quantitative real-time polymerase chain reaction. The calcium flux assay was used to examine the biological activities of SCFAs in human neutrophils and monocytes. The effect ofSCFAs on human monocytes and peripheral blood mononuclear cells (PBMC) was studied by measuring PGE2,cytokines and chemokines in the supernatant. The effect of SCFAs in vivo was examined by intraplantar injection into rat paws.RESULTS:Human GPR43 is highly expressed in human neutrophils and monocytes. SCFAs induce robust calcium flux in human neutrophils,but not in human monocytes. In this study,we show that SCFAs can in-duce human monocyte release of PGE2 and that this effect can be enhanced in the presence of lipopolysac-charide (LPS). In addition,we demonstrate that PGE2 production induced by SCFA was inhibited by pertussis toxin,suggesting the involvement of a receptor-mediated mechanism. Furthermore,SCFAs can specifi cally inhibit constitutive monocyte chemotactic protein-1 (MCP-1) production and LPS-induced interleukin-10 (IL-10) production in human monocytes without affecting the secretion of other cytokines and chemokines examined. Similar activities were observed in human PBMC for the release of PGE2,MCP-1 and IL-10 after SCFA treatment. In addition,SCFAs inhibit LPS-induced production of tumor necrosis factor-α and interferon-γ in human PBMC. Finally,we show that SCFAs and LPS can induce PGE2 production in vivo by intraplantar injection into rat paws (P < 0.01). CONCLUSION:SCFAs can have distinct antiinflammatory activities due to their regulation of PGE2,cytokine and chemokine release from human immune cells. | Mary Ann Cox James Jackson Michaela Stanton Alberto Rojas-Triana Loretta Bober Maureen Laverty Xiaoxin Yang Feng Zhu Jianjun Liu Suke Wang Frederick Monsma Galya Vassileva Maureen Maguire Eric Gustafson Marvin Bayne Chuan-Chu Chou Daniel Lundell Chung-Her Jenh | 2009 | World Journal of Gastroenterology2009,15,44: | 30 |
| 11 | Preliminary Scientific Results of Chang'E-1 Lunar Orbiter:Based on Payloads Detection Data in the First Phase显示文摘Chang'E-1 lunar Orbiter was launched by Long March 3A rocket from Xichang Satel-lite Launch Center at 18:05BT(Beijing Time) Oct.24,2007.It is the first step of its ambitious three-stage moon program,a new milestone in the Chinese space exploration history.The primary science objectives of Chang'E-1 lunar orbiter are to obtain three-Dimension(3D) stereo images of the lunar surface,to analyze the distribution and abundance of elements on the surface,to investigate the thickness of lunar soil,evaluate helium-3 resources and other characteristics,and to detect the space environment around the moon.To achieve the above four mission objectives,eight sets of scientific instruments are chosen as the payloads of the lunar orbiter,including a CCD stereo camera(CCD),a Sagnac-based interferometer spectrometer(ⅡM),a Laser Altimeter(LAM),a Microwave Radiometer(MRM),a Gamma-Ray Spectrometer(GRS),an X-ray spectrometer(XRS),a High-Energy Particle Detector(HPD),and two Solar Wind Ion Detectors(SWID).The detected data of the payloads show that all payloads work well.This paper introduces the status of payloads in the first phase and preliminary scientific results. | OUYANG Ziyuan JIANG Jingshan LI Chunlai SUN Huixian ZOU Yongliao LIU Jianzhong LIU Jianjun ZHAO Baochang REN Xin YANG Jianfeng ZHANG Wenxi WANG Jianyu MOU Lingli CHANG Jin ZHANG Liyan WANG Huanyu LI Yongquan ZHANG Xiaohui ZHENG Yongchun WANG Shijin BIAN Wei | 2008 | 空间科学学报2008,28,5: | 24 |
| 12 | Zircon U-Pb dating confirms existence of a Caledonian scheelite-bearing aplitic vein in the Penggongmiao granite batholith, South Hunan显示文摘Granite at Penggongmiao is a large batholith in the Nanling Range, with an outcrop area of over 900 km 2 . There are many scheelite-quartz veins around the granite. LA-ICP-MS U-Pb dating was carried out for zircons from the granite. The middlecoarse-grained biotite granite has U-Pb ages of 435 to 436 Ma. Ages of 426.5±2.5 Ma were obtained for aplitic dyke cross-cutting the granite. The scheelite of magmatic origin in the aplite dyke was identified from petrographic investigation. This demonstrates that W-bearing granites of Early Paleozoic (corresponding to the Caledonian orogensis in the traditional sense) occur in the Nanling Range. This finding has important implications for the ore-forming potential of Paleozoic granites and on the extent of Mesozoic mineralization. Thus it merits performing an intensive study of Paleozoic granites in South China. The occurrences of aplite or microgranite may be an indicative of the Caledonian tungsten granites and associated W mineralization. | ZHANG WenLan WANG RuCheng LEI ZeHeng HUA RenMin ZHU JinChu LU JianJun XIE Lei CHE XueDong ZHANG RongQing YAO Yuan CHEN Jun | 2011 | Chinese Science Bulletin2011,56,19: | 23 |
| 13 | Cardiotoxicity of 5-fluorouracil and capecitabine in Chinese patients: a prospective study显示文摘Background:5-Fluorouracil(5-FU)and capecitabine-associated cardiotoxicity ranging from asymptomatic electro-cardiography(ECG)abnormalities to severe myocardial infarction has been reported in a number of studies,but such cardiotoxicity in Chinese patients with malignant diseases has not been investigated to date.In the present study,we aimed to prospectively evaluate the incidence rates and clinical manifestations of 5-FU-and capecitabine-associated cardiotoxicity in cancer patients recruited from multiple centers in China.Methods:Among the 527 patients who completed the study,196 received 5-FU-based chemotherapy and 331 received capecitabine-based chemotherapy as either first-line or adjuvant therapy.Adverse events were reported during the treatment and up to 28 days of follow-up.Outcome measures included ECG,myocardial enzymes,cardiac troponin,brain natriuretic peptide and echocardiography.Univariate analysis and logistic regression were performed for subgroup analysis and identification of significant independent variables that are associated with cardiotoxicity of both agents.Results:In total,161 of 527 patients(30.6%)experienced cardiotoxicity.The incidence rate of cardiotoxicity was 33.8%(112/331)in the capecitabine group,which was significantly higher than the rate of 25%(49/196)in the 5-FU group(P=0.0042).110/527 patients(20.9%)suffered arrhythmia,105/527(19.9%)developed ischemic changes,while only 20/527 patients(3.8%)presented heart failure and 6/527 patients(1.1%)had myocardial infarction.Pre-existing cardiac disease,hypertension,capecitabine-based chemotherapy and duration of treatment were identified as sig-nificant risk factors associated with cardiotoxicity.The odds ratio were 15.7(prior history of cardiac disease versus no history),1.86(capecitabine versus 5-FU),1.06(5-8 versus 1-4 chemotherapy cycles)and 1.58(hypertension versus no hypertension),respectively.Conclusions:Cardiotoxicity induced by fluoropyrimidines in the Chinese population may be underestimated in clini-cal practice.Close monitoring of patients is recommended,especially for those patients at high risk for cardiotoxicity.Possible risk factors are duration of treatment,capecitabine-based chemotherapy,pre-existing cardiac diseases and hypertension.Trial registration This study was initiated on January 22,2014 and has been retrospectively registered with the registra-tion number ChiCTR1800015434 . | Jianjun Peng Chao Dong Chang Wang Weihua Li Hao Yu Min Zhang Qun Zhao Bo Zhu Jun Zhang Wenliang Li Fenghua Wang Qiong Wu Wenhao Zhou Ying Yuan Meng Qiu Gong Chen | 2018 | Cancer Communications2018,38,1: | 23 |

| 16 | Effects of overlying water aeration on phosphorus fractions and alkaline phosphatase activity in surface sediment显示文摘Microbial activity may influence phosphorus (P) deposit and release at the water sediment interface.The properties of DO (dissolved oxygen),pH,P fractions (TP,Ca-P,Fe-P,OP,IP),and APA (alkaline phosphatase activity) at the water sediment interface were measured to investigate microbial activity variations in surface sediment under conditions of two-month intermittent aeration in overlying water.Results showed that DO and TP of overlying water increased rapidly in the first week and then decreased gradually after 15 day of intermittent aeration.Microorganism metabolism in surface sediment increased pH and decreased DO and TP in the overlying water.After two-month intermittent aeration,APA and OP from surface sediment (0-2 cm) were both significantly higher than those from bottom sediment (6-8 cm) (p < 0.05),and surface sediment Fe-P was transferred to OP during the course of microorganism reproduction on the surface sediment.These results suggest that microbial activity and microorganism biomass from the surface sediment were higher than those from bottom sediment after two-month intermittent aeration in the overlying water. | Jianjun Chen Shaoyong Lu Yikun Zhao Wei Wang Minsheng Huang | 2011 | Journal of Environmental Sciences2011,23,2: | 20 |

| 20 | High-resolution data collection for analysis of sediment dynamic processes associatedwith combined current-wave action over intertidal flats显示文摘An MIDAS-400 Customised Data Ac- quisition System was deployed to obtain current ve- locity and suspended sediment concentration profiles over the intertidal flat at Wanggang, on the Jiangsu coast (China). At the same time, seawater tempera- ture, conductivity and pressure were measured. Us- ing a data sampling rate of 4 Hz, the high-frequency pressure signals in response to water surface fluc- tuations were recorded and subsequently trans- formed into wave parameters. The analytical results show that the apparent bed roughness length has a magnitude close to the height of sand ripples, which is much larger than the grain size diameter. The bot- tom shear stress associated with current-wave in- teraction is higher than the tidally-induced stress and intensified turbulent mixing and resuspension. Fur- thermore, several suspended sediment concentration peaks occurred during a tidal cycle, which can be related to strong turbulence near the bed caused by frontal tidal currents and the enhanced resuspension; advection and extreme weather conditions (e. g. storms and strong winds) also played an important role. Finally, large net suspended sediment fluxes were observed to present when the flood or ebb currents prolonged, i.e. the flow became quasi-unid- irectional during a tidal cycle. In general, the MIDAS- 400 is a suitable tool for high-resolution data collec- tion for the situations of combined current-wave ac- tion over intertidal flats; the data obtained can be used to analyze the processes and mechanisms of material transport. | WANG Yaping GAO Shu JIA Jianjun | 2006 | Chinese Science Bulletin2006,51,7: | 17 |
