| 1 | Anomaly Models of Spatial Structures for Copper-Molybdenum Ore Deposits and their Application显示文摘This paper discusses the enrichment and depletion regularities for porphyry copper-molybdenum ore deposits in different regions and varied deposit genetic types in the same area, taking three porphyry copper-molybdenum ore deposits (i.e., the Chengmenshan in Jiangxi, Wunugetushan in Inner Mongolia, Baishantang in Gansu) and two copper deposits in Gansu Province (the Huitongshan skarn deposit and Gongpoquan composite deposit) as case studies. The results show that porphyry Cu-Mo deposits or skarn copper deposits include both enrichment of the ore-forming elements and associated elements, and depletion of some lithophile dispersed elements, rare earth elements (REE) and some major elements. And the depleted elements vary with deposits, having generality and their own features. On a deposit scale, the positive anomalies of enriched elements and negative anomalies of depleted elements follow in a sequence to comprise regular anomaly models of spatial structures. The exploration in the Tongchang deposit in Jiangxi and Huitongshan deposit in Gansu suggests that anomaly models play a key role in the identification of mineral occurrences and deposits compared to one single enriched element anomaly. And the anomaly models exert a critical effect on the optimization of prospecting targets and their potential evaluation. | MA Shengming ZHU Lixin LIU Chongmin XI Mingjie TANG Shixin | 2013 | Acta Geologica Sinica(English Edition)2013，87，3： | 9 |
| 2 | Dark matter direct search sensitivity of the PandaX-4T experiment显示文摘The Panda X-4T experiment, a 4-ton scale dark matter direct detection experiment, is being planned at the China Jinping Underground Laboratory. In this paper we present a simulation study of the expected background in this experiment. In a 2.8-ton fiducial mass and the signal region between 1-10 keV electron equivalent energy, the total electron recoil background is found to be 4.9 × 10^(-5) kg^(-1) d^(-1) keV^(-1). The nuclear recoil background in the same region is 2.8 × 10^(-7) kg^(-1) d^(-1) keV^(-1). With an exposure of 5.6 ton-years, the sensitivity of Panda X-4 T could reach a minimum spin-independent dark matter-nucleon cross section of 6 × 10^(-48) cm^2 at a dark matter mass of 40 Ge V/c^2. | HongGuang Zhang Abdusalam Abdukerim Wei Chen Xun Chen YunHua Chen XiangYi Cui BinBin Dong DeQing Fang ChangBo Fu Karl Giboni Franco Giuliani LinHui Gu XuYuan Guo ZhiFan Guo Ke Han ChangDa He ShengMing He Di Huang XingTao Huang Zhou Huang Peng Ji XiangDong Ji YongLin Ju ShaoLi Li Yao Li Heng Lin HuaXuan Liu JiangLai Liu YuGang Ma YaJun Mao KaiXiang Ni JinHua Ning XiangXiang Ren Fang Shi AnDi Tan AnQing Wang Cheng Wang HongWei Wang Meng Wang QiuHong Wang SiGuang Wang XiuLi Wang XuMing Wang Zhou Wang MengMeng Wu ShiYong Wu JingKai Xia MengJiao Xiao PengWei Xie BinBin Yan JiJun Yang Yong Yang ChunXu Yu JuMin Yuan JianFeng Yue Dan Zhang Tao Zhang Li Zhao QiBin Zheng JiFang Zhou Ning Zhou XiaoPeng Zhou | 2019 | Science China(Physics,Mechanics & Astronomy)2019，62，3： | 6 |
| 3 | Extractant(2,3-dimethylbutyl)(2,4,40-trimethylpentyl) phosphinic acid(INET-3) impregnated onto XAD-16 and its extraction and separation performance for heavy rare earths from chloride media显示文摘(2,3-Dimethylbutyl)(2,4,40-trimethylpentyl)phosphinic acid(INET-3) was impregnated onto dry macroporous resins XAD-16 and pretreated XAD-16 with ethyl alcohol and HCl(Pre-XAD-16) to prepare the solvent impregnated resins SIRs-INET-3/XAD-16 and SIRs-INET-3/Pre-XAD-16. The molecular weight distribution of the low molecular weight(LMW) polymers washed off by ethyl alcohol during XAD-16 pretreatment was determined by gel permeation chromatography(GPC). The macroporous resins(XAD-16 & Pre-XAD-16), the corresponding solvent impregnated resins(SIRs-INET-3/XAD-16 &SIRs-INET-3/Pre-XAD-16) and the PVA coated SIRs-INET-3/Pre-XAD-16 with boric acid as cross-linking agent were characterized by FT-IR, SEM-EDS and TGA. The effects of XAD-16 pretreatment and PVA coating technology on RE(III) adsorption equilibrium time, INET-3 losses during extraction and adsorption capacity were investigated. The adsorption kinetics, selectivity and stripping behaviors of SIRs-INET-3/XAD-16 were further studied. The washed off LMW polymers had the Mn of 36,656, Mw of 40,310 and polydispersity coefficient of 1.10. The SIRs-INET-3/XAD-16 had shorter equilibrium time,less INET-3 loss and more Tm(III) adsorption capacity than the SIRs-INET-3/Pre-XAD-16. The PVA coated SIRs-INET-3/Pre-XAD-16 had less INET-3 loss and more Tm(III) adsorption capacity but longer equilibrium time than the uncoated SIRs-INET-3/Pre-XAD-16. The adsorption of RE(III) on the SIRsINET-3/XAD-16 followed the pseudo-second-order kinetic model. The Tm(III) accumulative adsorption amounts onto SIRs-INET-3/XAD-16 after eight extraction stages was 23.6 mg/g. The separation factors of adjacent heavy RE(III) β_(Er/Ho), β_(Tm/Er), β_(Yb/Tm) and β_(Lu/Yb) values were 1.76, 2.59, 2.56 and 1.19,respectively. The adsorbed Lu(III) onto the SIRs-INET-3/XAD-16 can be stripped completely by 1.0 mol/L H_2SO_4. | Junlian Wang Meiying Xie Juanjuan Ma Huajun Wang Shengming Xu | 2017 | Journal of Rare Earths2017，35，12： | 5 |

| 7 | Study of low bit rate speech codec algorithm in underwater acoustic communication显示文摘At medium or long distance(> 10 km) underwater acoustic speech communication,information transfer rate is constrained by the complicated,time varying channel and limited bandwidth.The bit rate of speech coding is required to be as low as possible.The time delay of underwater acoustic wave propagation can be used for low bit rate speech coding.After investigating the Mixed Excitation Linear Prediction(MELP) standard and taking account of the auditory perceptual features,a variable and adjustable bit rate speech codec algorithm has been proposed,whose average bit rate is about 600 bps.The average Perceptual Evaluation of Speech Quality Mean Opinion Score(PESQ MOS) of synthesized speeches is about 2.8.It has been proved by the computer simulation and sea trial that the performance of the proposed algorithm is well and robust when bit error rate is no more than 10^(-3).The synthesized speech is vivid and intelligible,and keeps main individual characteristics of speaker. | XIAO Dong MO Fuyuan CHEN Geng GUO Shengming MA Li | 2013 | Chinese Journal of Acoustics2013，32，4： | 4 |
| 8 | Highly Selective Nucleophilic 4-Aryl-2,3-allenylation of Malonates显示文摘of main observation and conclusion Allenes are a class of very important compounds and the development of straightforward,efficient,and highly enantioselective synthetic strategies for allenes have attracted extensive interests.Along this line,it is well known that aryl-substituted allenes may be readily racemized,thus,difficult to prepare in high ee.Herein,an efficient palladium-catalyzed nucleophilic allenylation of malonates w ith racemic 4-aryl-2,3-butadienyl carbonates has been developed.The selectivity issue of mono-vs.bis-allenylation with 2-non-substituted malonates has been addressed.By utilizing(R)-(-)-DTBM-SEGPHOS(5,5'-bisldi(3,5,-di-t-butyl-A-methoxyphenyOphosphino)-4,4'-bi-l,3-benzodioxole)as a chiral ligand,various aryl-substituted allenes and bisallenes have been prepared with good to excellent yields with high chemoselectivity and enantioselectivity under mild reaction conditions.Au-catalyzed cycloisomerization and APK(allenic Pauson-Khand)reactions affording optically active mono-and bicyclic products have been demonstrated. | Shihua Song Shengming Ma | 2020 | Chinese Journal of Chemistry2020，38，11： | 4 |

| 11 | First experimental constraints on WIMP couplings in the effective field theory framework from CDEX显示文摘We present weakly interacting massive particles(WIMPs) search results performed using two approaches of effective field theory from the China Dark Matter Experiment(CDEX), based on the data from both CDEX-1B and CDEX-10 stages. In the nonrelativistic effective field theory approach, both time-integrated and annual modulation analyses were used to set new limits for the coupling of WIMP-nucleon effective operators at 90% confidence level(C.L.) and improve over the current bounds in the low mχregion. In the chiral effective field theory approach, data from CDEX-10 were used to set an upper limit on WIMP-pion coupling at 90% C.L. We for the first time extended the limit to the m_(χ)<6 GeV/c^(2) region. | Yi Wang Zhi Zeng Qian Yue LiTao Yang KeJun Kang YuanJing Li Mehment Agartioglu HaiPeng An JianPing Chang JingHan Chen YunHua Chen JianPing Cheng Cheng Yi Chiang WenHan Dai Zhi Deng ChangHao Fang XinPing Geng Hui Gong QiuJu Guo XuYuan Guo HongJian He Li He ShengMing He JinWei Hu TuChen Huang HanXiong Huang HaiTao Jia LiPing Jia Xi Jiang HauBin Li JianMin Li Jin Li MingXuan Li RenMingJie Li Xia Li YuLan Li Bin Liao FongKay Lin ShinTed Lin ShuKui Liu YanDong Liu Yu Liu YuanYuan Liu ZhongZhi Liu Hao Ma YuCai Mao QiYuan Nie JinHua Ning Hui Pan NingChun Qi Jie Ren XiChao Ruan ChangSong Shang Vivek Sharma Ze She Lakhwinder Singh Monoj Kumar Singh TianXi Sun ChangJian Tang WeiYou Tang Yang Tian GuangFu Wang Li Wang Qing Wang Yu Chen Wang YunXiang Wang Zhen Wang Henry Tsz-King Wong ShiYong Wu YuCheng Wu HaoYang Xing Yin Xu Tao Xue YuLu Yan Nan Yi ChunXu Yu HaiJun Yu JianFeng Yue Ming Zeng BingTao Zhang Lei Zhang FengShou Zhang ZhenYu Zhang KangKang Zhao MingGang Zhao JiFang Zhou ZuYing Zhou JingJun Zhu | 2021 | Science China(Physics,Mechanics & Astronomy)2021，64，8： | 3 |

| 13 | A methodology to achieve the basis function for the expansion of sound speed profile显示文摘In order to evaluate the reliability and applicability of the Empirical Orthogonal Functions(EOFs)in the acoustic inversion of sound speed profile(SSP)and reduce EOF's dependence on the sample data,a methodology is proposed for the achievement of the basis functions for SSP's expansion.By analyzing the oceanographic dynamics which is the main cause of the SSP's variation,the basis functions are obtained naming the Hydrodynamic Normal Modes(HNMs).The HNM basis functions are almost the same as those derived from the EOF method,while HNMs has less dependence on the amount of the sample data.HNMs method has a physically meaningful interpretation,and it could give out the physical parameters which determine the basis functions for the expansion of SSP,and this makes it possible to analyze and evaluate the trustiness and applicability of EOFs. | SONG Wenhua HU Tao GUO Shengming MA Li LU Licheng | 2014 | Chinese Journal of Acoustics2014，33，3： | 2 |
| 14 | De novo synthesis of bifunctional conjugated microporous polymers for synergistic coordination mediated uranium entrapment显示文摘This work reports a de novo synthesis of novel bifunctional conjugated microporous polymers(CMPs)exhibiting a synergistic-effect involved coordination behavior to uranium.It is highlighted that the synthetic strategy enables the engineering of the coordination environment within amidoxime functionalized CMP frameworks by specifically introducing ortho-substituted amino functionalities,enhancing the affinity to uranyl ions via forming synergistic complexes.The CMPs exhibit high Brunauer-Emmett-Teller(BET)surface area,well-developed three-dimensional(3D)networks with hierarchical porosity,and favorable chemical and thermal stability because of the covalently cross-linked structure.Compared with the amino-free counterparts,the adsorption capacity of bifunctional CMPs was increased by almost 70%,from 105 to 174 mg/g,indicating evidently enhanced binding ability to uranium.Moreover,new insights into coordination mechanism were obtained by in-depth X-ray photoelectron spectroscopy(XPS)analysis and density functional theory(DFT)calculation,suggesting a dominant role of the oxime ligands forming a 1:1 metal ions/ligands(M/L)coordination model with uranyl ions while demonstrating the synergistic engagement of the amino functionalities via direct binding to uranium center and hydrogen-bonding involved secondary-sphere interaction.This work sheds light on the underlying principles of ortho-substituted functionalities directed synergistic effect to promote the coordination of amidoxime with uranyl ions.And the synthetic strategy established here would enable the task-specific development of more novel CMP-based functional materials for broadened applications. | Boxuan Yu Lei Zhang Gang Ye Qingzhi Liu Jiongli Li Xudong Wang Jing Chen Shengming Xu Shengqian Ma | 2021 | Nano Research2021，14，3： | 2 |

| 16 | LW-NIR hyperspectral imaging for rapid prediction of TVC in chicken flesh显示文摘Total viable count(TVC)is often used as an important indicator for chicken freshness evaluation.In this study,112 fresh chicken flesh samples were acquired after slaughtered and their hyperspectral images were collected in the LW-NIR(900-1700 nm)range.The full LW-NIR spectra(486 wavebands)within the images were extracted and applied to related to reference TVC values measured in different storage periods,using partial least squares regression(PLSR)algorithm,resulting in high correlation coefficients(R)and low root mean square errors(RMSE),for either raw spectra or pretreatment spectra.By using regression coefficients(RC)method,20,18,17 and 20 optimal wavebands were respectively selected from raw spectra,baseline correction(BC)spectra,Savitzky-Golay convolution smoothing(SGCS)spectra and standard normal variate(SNV)spectra and applied for the optimization of original full waveband PLSR model.By comparison,RC-PLSR model based on the SGCS spectra showed a better performance in TVC prediction with RC of 0.98 and RMSEC of 0.35 log10 CFU/g in calibration set,and RP of 0.98 and RMSEP of 0.44 log10 CFU/g in prediction set.At last,by transferring the best RC-PLSR model,the dynamic TVC change during the storage was visualized by color maps to indicate the TVC spoilage degree.The overall study revealed that LW-NIR hyperspectral imaging combined with PLSR could be used to predict the freshness of chicken flesh. | Hui Wang Hongju He Hanjun Ma Fusheng Chen Zhuangli Kang Mingming Zhu Zhengrong Wang Shengming Zhao Rongguang Zhu | 2019 | International Journal of Agricultural and Biological Engineering2019，12，3： | 2 |
| 17 | Quick assessment of chicken spoilage based on hyperspectral NIR spectra combined with partial least squares regression显示文摘Pseudomonas spp.and Enterobacteriaceae are dominant spoilage bacteria in chicken during cold storage(0°C-4°C).In this study,high resolution spectra in the range of 900-1700 nm were acquired and preprocessed using Savitzky-Golay convolution smoothing(SGCS),standard normal variate(SNV)and multiplicative scatter correction(MSC),respectively,and then mined using partial least squares(PLS)algorithm to relate to the total counts of Pseudomonas spp.and Enterobacteriaceae(PEC)of fresh chicken breasts to predict PEC rapidly.The results showed that with full 900-1700 nm range wavelength,MSC-PLS model built with MSC spectra performed better than PLS models with other spectra(RAW-PLS,SGCS-PLS,SNV-PLS),with correlation coefficient(RP)of 0.954,root mean square error of prediction(RMSEP)of 0.396 log10 CFU/g and residual predictive deviation(RPD)of 3.33 in prediction set.Based on the 12 optimal wavelengths(902.2 nm,905.5 nm,923.6 nm,938.4 nm,946.7 nm,1025.7 nm,1124.4 nm,1211.6 nm,1269.2 nm,1653.7 nm,1691.8 nm and 1693.4 nm)selected from MSC spectra by successive projections algorithm(SPA),SPA-MSC-PLS model had RP of 0.954,RMSEP of 0.397 log10 CFU/g and RPD of 3.32,similar to MSC-PLS model.The overall study indicated that NIR spectra combined with PLS algorithm could be used to detect the PEC of chicken flesh in a rapid and non-destructive way. | Shengqi Jiang Hongju He Hanjun Ma Fusheng Chen Baocheng Xu Hong Liu Mingming Zhu Zhuangli Kang Shengming Zhao | 2021 | International Journal of Agricultural and Biological Engineering2021，14，1： | 2 |
