| 4 | Helium,Argon,and Xenon Isotopic Compositions of Ore-forming Fluids in Jinding-Baiyangping Polymetallic Deposits,Yunnan,Southwest China显示文摘The Jinding superlarge lead and zinc deposit has attracted the attention of geologists of the world and itsmetal logenesis has long been in dispute. This paper takes the Jinding deposit and the Baiyangping Cu-Ag-Co deposit which was recently found at about 30 km north of Jinding as one ore belt, and, based on researches on the helium, argon, and xenon isotopic compositions of primary inclusions in ore-forming solutions of the main stage, the authors have found that the 3He/4He ratio of the ore-forming fluid is 2.7×10-6 (varying from 0.19 to 1.97 Ra), the 4He/40Ar ratio (0.24-3.12) is close to the mantle characteristic ratio, and the xenon isotopic composition and evolution show characters of the mantle xenon. The above results reveal the characteristics of mantle source and crust-mantle fluid mixing (mantle helium reaching 32%) and the metallogenic contributions of the deep processes in the Jinding-Baiyangping ore belt. | XUE Chunji WANG Denghong CHEN Yuchuan YANG Jianmin YANG Weiguang | 2000 | Acta Geologica Sinica(English Edition)2000，74，3： | 17 |

| 6 | Transmutation of ancient settlements and environmental changes between 6000-2000 aBP in the Chaohu Lake Basin, East China显示文摘Based on the temporal-spatial distribution features of ancient settlement sites from the middle and late Neolithic Age to the Han dynasty in the Chaohu Lake Basin of Anhui Province,East China,using the methods of GIS combined with the reconstructed paleoenvironment by the records of lake sediment since Holocene,the transmutation of ancient settlements with response to environmental changes in this area has been discussed.Studies show that the main feature of transmutation of ancient settlements from the middle and late Neolithic Age to the Han Dynasty was that the distribution of settlements in this area changed from high altitudes to low ones and kept approaching the Chaohu Lake with the passage of time.These could be the response to the climate change from warm-moist to a relatively warm-dry condition during the middle Holocene,leading to the lake level fluctuations.The large area of exposed land provided enough space for human activities.These indicate that the above changes in geomorphologic evolution and hydrology influenced by climate conditions affected the transmutation of ancient settlements greatly.The distribution pattern of settlement sites was that the number of sites in the west was more than in the east.This pattern may be related to the geomorphologic conditions such as frequent channel shifting of the Yangtze River as well as flood disasters during the Holocene optimum.Therefore,climate change was the inducement of the transmutation of ancient settlements in the Chaohu Lake Basin,which exerted great influence on the distribution,expansion and development of the ancient settlements. | WU Li WANG Xinyuan ZHOU Kunshu MO Duowen ZHU Cheng GAO Chao ZHANG Guangsheng LI Lan LIU Li HAN Weiguang | 2010 | Journal of Geographical Sciences2010，20，5： | 16 |
| 7 | Evidence for a mouse origin of the SARS-CoV-2 Omicron variant显示文摘The rapid accumulation of mutations in the SARS-CoV-2 Omicron variant that enabled its outbreak raises questions as to whether its proximal origin occurred in humans or another mammalian host. Here, we identified 45 point mutations that Omicron acquired since divergence from the B.1.1 lineage. We found that the Omicron spike protein sequence was subjected to stronger positive selection than that of any reported SARS-CoV-2 variants known to evolve persistently in human hosts, suggesting a possibility of hostjumping. The molecular spectrum of mutations(i.e., the relative frequency of the 12 types of base substitutions) acquired by the progenitor of Omicron was significantly different from the spectrum for viruses that evolved in human patients but resembled the spectra associated with virus evolution in a mouse cellular environment. Furthermore, mutations in the Omicron spike protein significantly overlapped with SARS-CoV-2 mutations known to promote adaptation to mouse hosts, particularly through enhanced spike protein binding affinity for the mouse cell entry receptor. Collectively, our results suggest that the progenitor of Omicron jumped from humans to mice, rapidly accumulated mutations conducive to infecting that host,then jumped back into humans, indicating an inter-species evolutionary trajectory for the Omicron outbreak. | Changshuo Wei Ke-Jia Shan Weiguang Wang Shuya Zhang Qing Huan Wenfeng Qian | 2021 | Journal of Genetics and Genomics2021，48，12： | 16 |
| 8 | Application of Adaptive Kalman Filtering Algorithm in IMU/GPS Integrated Navigation System显示文摘The IMU(inertial measurement unit) error equations in the earth fixed coordinates are introduced firstly. A fading Kalman filtering is simply introduced and its shortcomings are analyzed, then an adaptive filtering is applied in IMU/GPS integrated navigation system, in which the adaptive factor is replaced by the fading factor. A practical example is given. The results prove that the adaptive filter combined with the fading factor is valid and reliable when applied in IMU/GPS integrated navigation system. | GAO Weiguang YANG Yuanxi CUI Xianqiang ZHANG Shuangcheng | 2007 | Geo-Spatial Information Science2007，10，1： | 13 |
| 9 | Study on the morphology, crystalline structure and thermal properties of yam starch acetates with different degrees of substitution显示文摘This study was carried out to understand and establish the changes in physicochemical properties of starch extracted from Chinese yam (Dioscorea opposita Thunb.) after acetylation. Yam starch acetates with different degrees of substitution (DS) were prepared by the reaction of yam starch with glacial acetic acid/acetic anhydride using sulfuric acid as the catalyst. Their formation was confirmed by the presence of the carbonyl signal around 1750 cm-1 in the Fourier transform infrared (FT-IR) spectra. The thermal behavior of the native starch and starch acetate were investigated using thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The results reveal that the starch acetates are more thermally stable than the native starch. The starch esters showed 50% weight loss at tem- peratures from 328℃ to 372 ℃ , while the native starch underwent 50% weight loss at 325℃ . The glass transition temperature (Tg) of the starch decreased from 273℃ to 226℃. The X-ray diffraction (XRD) patterns could be classified as typical of the C-type for yam starch. X-ray diffraction also showed the loss of the ordered C-type starch crystalline structure and the degree of crystallinity of starch de- creased from 36.10% to 10.96% with the increasing DS. The scanning electron microscopy (SEM) sug- gested that the most of the starch granules disintegrated with many visible fragments with the in- creasing DS. | WANG Xu GAO WenYuan ZHANG LiMing XIAO PeiGen YAO LiPing LIU Yi LI KeFeng XIE WeiGuang | 2008 | Science China Chemistry2008，51，9： | 11 |
| 10 | Thermodynamic conditions of framework grain dissolution of clastic rocks and its application in Kela 2 gas field显示文摘Feldspar and clastic debris are the most important constituent framework grains of sedimentary clastic rocks and their chemical dissolution plays an essential role in the formation and evolution of the secondary pore in the reservoir rocks. On the basis of thermodynamic phase equilibrium, this study investigates the chemical equilibrium relationships between fluid and various plagioclase and K-feldspar in diagenesis of the sediments, particularly, the impact of temperature and fluid compositions (pH, activity of K+, Na+, Ca2+ and so on) on precipitation and dissolution equilibria of feldspars. Feldspar is extremely easily dissolved in the acid pore water with a low salinity when temperature decreases. The dissolution of anorthite end-member of plagioclase is related to the Ca content of the mineral and the fluid, higher Ca either in the mineral or in the fluid, easier dissolution of the feldspar. Moreover, the dissolution of albite end-member of plagioclase is related to Na of both the mineral and fluid, lower Na out of both the mineral and fluid, easier dissolution of the mineral. Similarly, lower-K fluid is more powerful to dissolve K-feldspar than the higher. The anorthite component of plagioclase is most easily dissolved in ground water-rock system, the albite is the secondary, and K-feldspar is the most stable. Selective dissolution of plagioclase occurs in diagenesis because of the plagioclase solid solution that is mainly composed of albite and anorthite end-members, Ca-rich part of which is preferentially dissolved by the pore water, in contrast to the Na-rich parts. Based on investigation of reservoir quality, secondary pore, dissolution structures of feldspar, clay minerals and ground water chemistry of the Kela 2 gas field of Kuqa Depression in the Tarim basin of Western China, we discovered that the secondary pore is very well developed in the highest quality section of the reservoir, and the plagioclase of which was obviously selectively dissolved, in contrast to the overgrowth of K-feldspar. Chemistry of the ground water out of the highest quality section of the reservoir is consistent with the complete dissolution field of anorthite, partial dissolution field of albite component of plagioclase, and the precipitation of K-feldspar on the temperature-logK phase equilibrium diagram drawn from this study. The thermodynamic modeling calculation gave us an insight into formation of the secondary pore within the reservoir, and the dissolution of plagioclase an important cause of the secondary pore. It is assumed that the solvent to dissolve the plagioclase frame grains originated from the origin-enriched compacted fluid acids out of the mudstone buried beneath the top of geopressured zones in the Kuqa Depression. | LAI Xingyun, YU Bingsong, CHEN Junyuan, CHEN Xiaolin, LIU Jianqing, MEI Mingxiang, JING Weiguang & CHENG Suhua School of Earth Sciences and Mineral Resources, China University of Geosciences, Beijing 100083, China Key Laboratory of Lithospheric Tectonics, Deep-level Process and Exploration of Ministry of Education, Beijing 100083, China | 2005 | Science China Earth Sciences2005，48，1： | 9 |

| 12 | Unsteady Tip Clearance Flow in an Isolated Axial Compressor Rotor显示文摘The paper investigates effects of operating conditions, tip clearance sizes and external unsteady excitations on the unsteady tip clearance flow in an isolated axial compressor rotor by unsteady 3D Navier-Stokes simulations. The results show that the unsteady tip clearance vortex takes a periodic flow behavior in the rotor tip region. With the decrease of the flow coefficient, the unsteady tip clearance vortex is enhanced and its frequency becomes lower. A larger tip clearance size can cause bigger unsteady fluctuation amplitude and a lower fluctuation frequency of the tip clearance vortex at the near stall operating condition. The unsteady excitation with the natural frequency of the tip clearance vortex can enhance the unsteadiness of the tip clearance vortex and improve the overall rotor performance. The frequency of the unsteady tip clearance vortex is independent of external unsteady excitations with different frequencies. | Hongwu ZHANG Xiangyang DENG Jingyi CHEN Weiguang HUANG | 2005 | Journal of Thermal Science2005，14，3： | 9 |
| 13 | Bacterial Community and Function of Biological Activated Carbon Filter in Drinking Water Treatment显示文摘Objective It aims to investigate the changes in composition and structure of bacterial communities de-veloping on biological activated carbon (BAC) particles, and the bacterial functions. Method A pilot plant had been in service for 180 days, aiming to develop bacterial communities on acti-vated carbon naturally. After 180 days of operation, the bacterial communities were determined by dena-turing gradient gel electrophoresis (DGGE) analyses of PCR-amplified 16S rRNA genes. The study on community composition and the phylogenetic relationships of the organisms was complemented by a se-quence analysis of cloned PCR products from 16S rRNA genes. Gas chromatorgaphy-mass (GC-MS) mea-surement was used to determine organic chemical composition of inflow and outflow water on the 300th day. TOC and NH 4 + -N were also tested in this experiment. Results It showed that the stable bacterial structure did not develop on BAC particles until the 9th month during running time of the BAC filter. The communities were finally dominated by Pseudomonas sp., Ba-cillus sp., Nitrospira sp., and an uncultured bacterium. Stable bacterial communities played an important role in removal of NH 4 + -N and total organic carbon (TOC). Results from gas chromatorgaphy-mass (GC-MS) showed that 36 kinds of chemicals in feed water were eliminated, and concentrations of 5 kinds of chemicals decreased. These chemicals served as nutrients for the dominant bacteria. Conclusion The findings from the study suggested that the stability of microbial structure was beneficial for improving NH 4 + -N and TOC removal efficiencies. The dominant bacteria had the advantage of biode-grading a wide range of organic chemicals and NH 4 + -N. | ZHANG DuoYing LI WeiGuang ZHANG ShuMei LIU Miao ZHAO XiaoYu ZHANG XianCheng | 2011 | Biomedical and Environmental Sciences2011，24，2： | 8 |
| 14 | Graphene-enabled electrically controlled terahertz meta-lens显示文摘Metasurfaces have become a new photonic structure for providing potential applications to develop integrated devices with small thickness, because they can introduce an abrupt phase change by arrays of scatterers. To be applied more widely, active metasurface devices are highly desired. Here, a tunable terahertz meta-lens whose focal length is able to be electrically tuned by ~4.45λ is demonstrated experimentally. The lens consists of a metallic metasurface and a monolayer graphene. Due to the dependence of the abrupt phase change of the metasurface on the graphene chemical potential, which can be modulated using an applied gate voltage, the focal length is changed from 10.46 to 12.24 mm when the gate voltage increases from 0 to 2.0 V. Experimental results are in good agreement with the theoretical hypothesis. This type of electrically controlled meta-lens could widen the application of terahertz technology. | WEIGUANG LIU BIN HU ZONGDUO HUANG HONGYU GUAN HETING LI XINKE WANG YAN ZHANG HONGXING YIN XIAOLU XIONG JUAN LIU YONGTIAN WANG | 2018 | Photonics Research2018，6，7： | 8 |
| 15 | Optimization of endwall contouring in axial compressor S-shaped ducts显示文摘This paper presents a numerical investigation of the potential aerodynamic benefits of using endwall contouring in a fairly aggressive duct with six struts based on the platform for endwall design optimization.The platform is constructed by integrating adaptive genetic algorithm(AGA), design of experiments(DOE), response surface methodology(RSM) based on the artificial neural network(ANN), and a 3D Navier–Stokes solver.The visual analysis method based on DOE is used to define the design space and analyze the impact of the design parameters on the target function(response).Optimization of the axisymmetric and the non-axisymmetric endwall contouring in an S-shaped duct is performed and evaluated to minimize the total pressure loss.The optimal ducts are found to reduce the hub corner separation and suppress the migration of the low momentum fluid.The non-axisymmetric endwall contouring is shown to remove the separation completely and reduce the net duct loss by 32.7%. | Jin Donghai Liu Xiwu Zhao Weiguang Gui Xingmin | 2015 | Chinese Journal of Aeronautics2015，28，4： | 7 |
| 16 | A case-control study about the association between vascular endothelial growth inhibitor gene polymorphisms and breast cancer risk in female patients in Northeast China显示文摘Objective: The inhibition of the neovascularization in tumors is a potential therapeutic target of cancer. Vascular endothelial growth inhibitor(VEGI) is a member of the TNF superfamily which has the ability to suppress the formation of new vessels in tumors. In order to study the association between VEGI gene polymorphisms and breast cancer risk, a case-control study was conducted in Chinese Han women in Northeast China.Methods: Our study involved 708 female breast cancer patients and 685 healthy volunteers. Four SNPs of VEGI gene were analyzed through the polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP) method. The association between VEGI gene polymorphisms and breast cancer risk was analyzed in our study. The relation between VEGI gene variants and clinical features of breast cancer including lymph node(LN) metastasis, estrogen receptor(ER), progestrogen receptor(PR), tumor protein 53(p53), human epidermal growth factor receptor 2(Her-2) and triple negative(ER-/PR-/Her-2-) status was analyzed as well.Results: We found that the CT genotype and T allele of rs6478106 were more frequent in patients than in controls. There was also a statistical difference in the distribution of C_(rs6478106)G_(rs4263839) haplotype between patients and controls. In addition, SNP rs6478106 and rs4979462 were related with the Her-2 status.Conclusions: Our results suggest that VEGI gene variants may be related to the breast cancer risk and the clinical features of breast cancer in Chinese Han women in Northeast China. | Shaoli Han Lei Liu Fengyan Xu Shuang Chen Weiguang Yuan Zhenkun Fu Dalin Li Dianjun Li | 2016 | Chinese Journal of Cancer Research2016，28，4： | 7 |
| 17 | Potential land for plantation of Jatropha curcas as feedstocks for biodiesel in China显示文摘As a renewable energy,biofuel has attracted great attention in China and the rest of world.Concerned with the national food security,China recently has shifted its biofuel development priority from grain-based to non-grain-based biofuels,including forest-based biodiesel,since 2007.Jatropha curcas is one of major biodiesel feedstocks.However,there is rising debate on availability of land for expanding Jatropha curcas areas.The overall goal of this paper is to evaluate potential land for Jatropha curcas used as feedstock for biodiesel in China.Based on remote sensing data on land use,data on meteorological,soil and land slope,and suitable environment for Jatropha curcas plantation,this study uses Agro Ecological Zone method and considers social-economic constraints to evaluate potential suitable land for Jatropha curcas plantation in China's major Jatropha curcas production region,Southwest China.The results show that while there are some potential lands to expand Jatropha curcas areas,amount of these lands will hardly meet the government's target for Jatropha curcas-based biodiesels development in the future.China may need to reconsider its long-term targets on the development of Jatropha curcas-based biodiesels. | WU WeiGuang 1,2,3,HUANG JiKun 1,3 & DENG XiangZheng 1,3 1 Institute of Geographic Sciences and Natural Resources Research,Chinese Academy of Sciences,Beijing 100101,China 2 Department of Economics and Management,Zhejiang Forestry University,Linan 311300,China 3 Center for Chinese Agricultural Policy,Chinese Academy of Sciences,Beijing 100101,China | 2010 | Science China Earth Sciences2010，53，1： | 7 |

| 19 | Open-circuit Fault Diagnosis of Traction Inverter Based on Compressed Sensing Theory显示文摘This study proposes a new method of fault diagnosis based on the least squares support vector machine with gradient information(G-LS-SVM)to solve the insulated-gate bipolar transistor(IGBT)open-circuit failure problem of the traction inverter in a catenary power supply system.First,a simulation model based on traction inverter topology is built,and various voltage fault signal waveforms are simulated based on the IGBT inverter open-circuit fault classification.Second,compressive sensing theory is used to sparsely represent the voltage fault signal and make it a fault signal.The new method has a high degree of sparseness and builds an overcomplete dictionary model containing the feature vectors of voltage fault signals based on a double sparse dictionary model to match the sparse signal characteristics.Finally,the space vector transform is used to represent the three-phase voltage scalar in the traction inverter as a composite quantity to reduce the redundancy of the fault signals and data-processing capabilities.A G-LS-SVM fault diagnosis model is then built to diagnose and identify the voltage fault signal feature vector in an overcomplete dictionary.The simulation results show that the accuracy of this method for various types of IGBT tube fault diagnosis is over 98.92%.Moreover,the G-LS-SVM model is robust and not affected by Gaussian white noise. | Yongqi Cheng Weiguang Dong Fengyang Gao Guoqing Xin | 2020 | Chinese Journal of Electrical Engineering2020，6，1： | 6 |
| 20 | Crust and upper mantle structures beneath Northeast China from receiver function studies显示文摘P-wave and S-wave receiver function analyses have been performed along a profile consisted of 27broadband seismic stations to image the crustal and upper mantle discontinuities across Northeast China.The results show that the average Moho depth varies from about37 km beneath the Daxing'anling orogenic belt in the west to about 33 km beneath the Songliao Basin,and to about35 km beneath the Changbai mountain region in the east.Our results reveal that the Moho is generally flat beneath the Daxing'anling region and a remarkable Moho offset(about 4 km) exists beneath the basin-mountain boundary,the Daxing'anling-Taihang Gravity Line.Beneath the Tanlu faults zone,which seperates the Songliao Basin and Changbai region,the Moho is uplift and the crustal thickness changes rapidly.We interpret this feature as that the Tanlu faults might deeply penetrate into the upper mantle,and facilitate the mantle upwelling along the faults during the Cenozoic era.The average depth of the lithosphereasthenosphere boundary(LAB) is *80 km along the profile which is thinner than an average thickness of a continental lithosphere.The LAB shows an arc-like shape in the basin,with the shallowest part approximately beneath the center of the basin.The uplift LAB beneath the basin might be related to the extensive lithospheric stretching in theMesozoic.In the mantle transition zone,a structurally complicated 660 km discontinuity with a maximum 35 km depression beneath the Changbai region is observed.The35 km depression is roughly coincident with the location of the stagnant western pacific slab on top of the 660 km discontinuity revealed by the recent P wave tomography. | Zhen Guo Yuliang Cao Xianguang Wang Y.John Chen Jieyuan Ning Weiguang He Youcai Tang Yongge Feng | 2014 | Earthquake Science2014，27，3： | 6 |
