| 1 | Motion equations of hemispherical resonator and analysis of frequency split caused by slight mass non-uniformity显示文摘The mass non-uniformity of hemispherical resonator is one of reasons for frequency split,and frequency split can cause gyroscope to drift.Therefore,it is of great significance to analyze the relationship between mass non-uniformity and frequency split,which can provide a theoretical basis for mass balance of imperfect resonator.The starting point of error mechanism analysis for gyroscope is the motion equations of resonator.Firstly,based on the Kirchhoff-Love hypothesis in the elastic thin shell theory,the geometric deformation equations of resonator are deduced.Secondly,the deformation energy equation of resonator is derived according to the vibration mode and relationship between the stress and strain of hemispherical thin shell.Thirdly,the kinetic energy equation of resonator is deduced by the Coriolis theorem.Finally,the motion equations of resonator are established by the Lagrange mechanics principle.The theoretical values of precession factor and natural frequency are calculated by the motion equations,which are substantially consistent with the ones by the finite element method and practical measurement,the errors are within a reasonable range.Simultaneously,the varying trend of natural frequency with respect to the geometrical and physical parameters of resonator by the motion equations is consistent with that by the finite element analysis.The above conclusions prove the correctness and rationality of motion equations.Similarly,the motion equations of resonator with mass non-uniformity are established by the same modeling method in case of ignoring the input angular rate and damping,and the state equations with respect to the velocity and displacement of vibration system are derived,then twonatural frequencies are solved by the characteristic equation.It is concluded that one of reasons for frequency split is the 4 th harmonic of mass non-uniformity,and thus much attention should be paid to minimizing the 4 th harmonic of mass non-uniformity in the course of mass balancing for imperfect resonator. | Yan HUO Shunqing REN Guoxing YI Changhong WANG | 2020 | Chinese Journal of Aeronautics2020，33，10： | 7 |
| 2 | THE PLANNING AND MANAGEMENT INFORMATION SYSTEM FOR SMALL TOWN (TOWNMIS)——A CASE STUDY AT XIAOLAN TOWN, SOUTH CHINA显示文摘Now, GISs are popular at most major cities along the coast in China. The lack of available digital geographic data is a serious bottleneck problem. This article first analyses the development characteristics of urban planning and management information system in China, and proposes a method for establishing a planning and management information system for small town. By using GIS as core and integrating with microcomputer network, office automation (OA), computer aided design (CAD), and multimedia technology, a microcomputer information system (TownMIS) is implemented after 3 year design and development. It may be a first comprehensive system for the planning and management of small towns. Since the January of 1996, TownMIS has been actually used in Xiaolan Town, a coastal rich town in South China. This has provided perfect technical, managerial, operational and institutional references for resolving the contradiction of the fast growing installation of GIS sites and fewer actually running system. | Chen Shunqing State Key Lab. of Resources & Environment Information System Institute of Geography, CAS, Beijing 100101, P.

| 3 | Phosphorus utilization and microbial community in response to lead/iron addition to a waterlogged soil显示文摘Constructed wetlands have emerged as a viable option for helping to solve a wide range of water quality problems. However, heavy metals adsorbed by substrates would decrease the growth of plants, impair the functions of wetlands and eventually result in a failure of contaminant removal. Typha latifolia L., tolerant to heavy metals, has been widely used for phytoremediation of Pb/Zn mine tailings under waterlogged conditions. This study examined effects of iron as ferrous sulfate (100 and 500 mg/kg) and lead as lead nitrate (0, 100, 500 and 1000 mg/kg) on phosphorus utilization and microbial community structure in a constructed wetland. Wetland plants (T. latifolia) were grown for 8 weeks in rhizobags filled with a paddy soil under waterlogged conditions. The results showed that both the amount of iron plaque on the roots and phosphorus adsorbed on the plaque decreased with the amount of lead addition. When the ratio of added iron to lead was 1:1, phosphorus utilized by plants was the maximum. Total amount of phospholipids fatty acids (PLFAs) was 23%–59% higher in the rhizosphere soil than in bulk soil. The relative abundance of Gram-negative bacteria, aerobic bacteria, and methane oxidizing bacteria was also higher in the rhizosphere soil than in bulk soil, but opposite was observed for other bacteria and fungi. Based on cluster analysis, microbial communities were mostly controlled by the addition of ferrous sulfate and lead nitrate in rhizosphere and bulk soil, respectively. | ZHONG Shunqing | 2009 | Journal of Environmental Sciences2009，21，10： | 5 |
| 4 | Discovery of fossil monocotyledons from Yixian Formation, western Liaoning显示文摘This is the first reports of a few fossil monocotyledons, including \%Liaoxia chenii\% gen. et sp. nov. (belonging to Cyperaceae), \%Eragrosites changii\% gen. et sp. nov. (Gramineae) and a monocotyledonous leaf_shoot, obtained from the Late Jurassic Yixian Formation of western Liaoning Province, NE China. These fossils are the oldest known angiosperms in the world. It may be inferred that the earliest angiosperms probably appeared even earlier than the Late Jurassic. | Zhengyao Cao Shunqing Wu Ping’an Zhang Jieru Li | 1998 | Chinese Science Bulletin1998，43，3： | 5 |
| 5 | The influence of atmospheric Hg on Hg contaminations in rice and paddy soil in the Xunyang Hg mining district,China显示文摘To date, the Xunyang mercury(Hg) mining district is the only ongoing large-scale Hg mining district in China. To understand the influence of Hg contamination mode from the Hg mining and smelting activities, 27 sampling sites in the Xunyang Hg mining district were chosen in this study. Total gaseous mercury(TGM) in ambient air was measured using a Lumex-RA915 automatic Hg analyzer in2011. Rice samples and soil samples from rhizosphere were collected systematically and simultaneously. Total Hg(THg) and methylmercury(Me Hg) concentrations in rice grain and soil samples and Hg speciation with modified sequential selective extractions were measured. The local environment was seriously polluted with Hg. The TGM(302 ± 376 ng·m-3, ranging from 24 to 2220 ng·m^(-3)) in the local ambient air, THg(28 ± 30 mg·kg^(-1), ranging from 0.31 to 121 mg·kg^(-1)) and Me Hg(2.3 ± 1.9 lg·kg^(-1),ranging from 0.24 to 8.9 lg·kg^(-1)) in soil samples were at the sample level with Hg contaminated area. The THg concentration(26 ± 16 lg·kg^(-1)ranging from 4.5 to 71 lg·kg^(-1)) in most of the rice grain samples clearly exceeds the threshold level(20 lg·kg^(-1)) in the Chinese national guidelines for cereals(NY 861-2004). The inorganic mercury(IHg)(9.1 ± 5.6 lg·kg^(-1), ranging from 1.2 to 24 lg·kg^(-1)) and Me Hg(14 ± 9.8 lg·kg^(-1), ranging from 2.1 to 59 lg·kg^(-1))concentration in rice grain samples were at the same level with Hg contaminated area. The main species of Hg in paddy soils reveal strong complex Hg and residue Hg. According to the correlation analysis, a Hg pollution mode from local Hg mining and smelting was hypothesized, including Hg emission, transportation, methylation, and uptake process. | Ming Ao Bo Meng Atindra Sapkota Yonggui Wu Xiaoli Qian Guangle Qiu Shunqing Zhong Lihai Shang | 2017 | Acta Geochimica2017，36，2： | 5 |
| 6 | Assessment of estrogen disrupting potency in animal foodstuffs of China by combined biological and chemical analyses显示文摘Food has been documented as one of major routes for human exposure to environmental estrogens(EEs), but information on the occurrence of EEs in animal foodstuffs is still scarce.This study analyzed estrogenic activity in 16 types of animal foodstuffs(n = 142) collected from four cities(Wuhan, Guangzhou, Wenzhou and Yantai) of China by combined yeast estrogen screen(YES) bioassay and chemical analysis. By bioassay, all samples' extracts were found to induce estrogenic activities and the bioassay-derived 17β-estradiol equivalent(EEQbio) ranged from 8.29 to 118.32 ng/g. In addition, the samples were analyzed by liquid chromatography coupled to tandem mass spectrometry for further chemical analysis. 17β-Estradiol was found in all samples in this survey at levels of 0.44 to 15.04 ng/g.All samples had 33.1% detection rate of 17α-ethinylestradiol(EE2), and the maximum concentration was 2.80 ng/g. Bisphenol A and 4-nonylphenols were detected in 83.8% and83.1% of samples, with concentrations up to 12.56 ng/g and 35.76 ng/g, respectively.However, the concentrations of estrone, diethylstilbestrol and 4-t-octylphenol were found to be below the limit of detection. A comparison of EEQbiomeasured from the YES assay and EEQchemcalculated from chemical analysis showed good correlation(R2= 0.84). Based on the results, the YES assay can be used as a rapid pre-screening method for monitoring the levels of estrogenic activity in large numbers of animal foodstuffs, and chemical analysis used in combination can be used for the identification of specific EEs. | Jun Wang Wei Xia Yonghua Xiao Chenjiang Ying Jia Long Hui Zhang Xi Chen Congda Mao Xiumin Li Lin Wang Shunqing Xu | 2014 | Journal of Environmental Sciences2014，26，10： | 4 |
| 7 | Exposure to persistent organic pollutants as potential risk factors for developing diabetes显示文摘Persistent organic pollutants(POPs),such as dioxins,polychlorinated biphenyls(PCBs) ,and organochlorine pesticides(OCPs),which are synthetic chemicals or by-products with an intrinsic resistance to natural degradation processes,are released into the environment,resulting in the widespread dispersal and accumulation in the environment,as well as in human and ecological food chains.Due to their ubiquity in the environment and lipophilic properties,there is emerging concern over the potential risks of human exposure to POPs.Extensive growing evidence indicated that exposure to POPs might be strongly associated with increased risk of a worldwide epidemic of diabetes,especially type 2 diabetes,suggesting that POPs might play a key role in their pathogenesis.Based on summary of the related studies,this paper reviews the epidemiologic and experimental data that addresses the association between increased risk of diabetes and POP exposure,including dioxins,PCBs,OCPs,polybrominated flame retardants(PBFRs),and some environmental estrogens.The potential mechanisms whereby POPs cause diabetes were discussed,such as alterations in lipid metabolism,in glucose transport,in insulin signaling pathway,in steroid metabolism,and disruption of endocrine system,induction of tumor necrosis factor-α(TNF-α) .However,with respect to diabetes,some of the evidence on POPs linked to risk of diabetes was suggestive of a direct or indirect association but was limited or inconclusive.Future research is urgently needed for determining the relative contribution of POPs to diabetes and elucidating the exact mechanisms. | WANG ChunXiang,XU ShunQing,LV ZiQuan,LI YuanYuan,WANG YouJie & CHEN Tian Key Laboratory of Environment and Health,Ministry of Education School of Public Health,Tongji Medical College,Huazhong University of Science and Technology,Wuhan 430030,China | 2010 | Science China Chemistry2010，53，5： | 3 |

| 10 | Simultaneous determination of bisphenols, benzophenones and parabens in human urine by using UHPLC-TQMS显示文摘Bisphenols, benzophenones and parabens may alter one or more functions of endocrine system and consequently cause adverse health effects on human. A rapid and sensitive analytical method for the simultaneous determination of six bisphenols, five benzophenones and seven parabens in human urine by using ultra-high performance liquid chromatography coupled with triple quadrupole mass spectrometry was developed and applied for human urine sample analysis. The eighteen targeted compounds were separated within 11 min. Heated-electrospray ionization was operated with multiple reaction monitoring in negative-ion mode. The limit of detection ranged from 0.01 ng/mL to 0.5 ng/mL.Seven isotope-labeled internal standards were used in the quantitative analysis. After the method was validated for sensitivity, linearity, precision, accuracy and matrix effect, it was applied for the analysis of human urine samples to evaluate the profiles of human exposure. Eight of the targeted analytes were detected in more than 50% urine samples. | Hongzhi Zhao Jiufeng Li Xinli Ma Wenqian Huo Shunqing Xu Zongwei Cai | 2018 | Chinese Chemical Letters2018，29，1： | 3 |

| 12 | The Discourse of Chinese Literary Theory and the Dialogue between Western Literary Theory and Chinese Literary Theory显示文摘有人认为中国文论话语是指诸如气、风骨、神韵、比兴、妙悟、意境等范畴。但是如果我们从文化的视角来分析,可以看出中国文论话语并不是指上述这些范畴,而是指中国文学表述自有的一套规则。古人言:'书不尽言,言不尽意。'中国学者坚信'立象'才是'尽意'的唯一途径,这正是中国文论一直强调的话语方式。本文在前人研究基础上,指出中国文论话语的基本特征,提出了中西异质文论对话的四个指导原则和五条具体途径,试图使中西文论对话理论进一步具体化和系统化。 | Cao,Shunqing Sichuan University | 2007 | Comparative Literature:East & West2007，，2： | 2 |
| 13 | Calibration method of quartz accelerometer on dynamic centrifuge显示文摘This paper proposes a novel method for calibrating error coefficients of the quartz accelerometer faster on the dynamic centrifuge,which can generate a continuous dynamic acceleration excitation.Firstly,working principle and structure of the dynamic centrifuge are analyzed,the error sources and the uncertainty of the dynamic centrifuge are expounded,and relevant coordinate systems are established.Then,according to the characteristics of the input specific forces and the propagating methods of the error sources,the accurate input specific forces acted on the input reference axes of accelerometer are obtained.Based on the calibration error model of the accelerometer,the corresponding dynamic calibration method is proposed.Finally,the second-order and high-order coefficients of the acceleration error model are calibrated,and the calibration precision of the coefficients is analyzed.Compared with traditional calibration methods,the method proposed in this paper not only greatly enhances the calibration efficiency by reducing the installing positions of the accelerometer,but also separates the centrifuge errors from the outputs of the accelerometer,which improves the accuracy and efficiency of the calibration method simultaneously. | Yingbo SUN Shunqing REN Changhong WANG | 2022 | Chinese Journal of Aeronautics2022，35，6： | 2 |
| 14 | Trimester-specific urinary metabolome alterations associated with gestational diabetes mellitus:A study in different pregnancy stages显示文摘Gestational diabetes mellitus(GDM),a frequently-occurring disease during pregnancy,may cause some adverse healthy outcome of both mother and offspring.However,the knowledge about metabolite alterations during the pathogenesis and development process is limited.Here,a large longitudinal nontargeted metabolomics study of 195 pregnant women(64 women with subsequently developed GDM and131 healthy controls)was conducted.Each participant provided urine samples at three timepoints during early,middle and late pregnancy,respectively.The metabolic profiles of 585 urine samples(195×3)were measured by using ultra-high performance liquid chromatography coupled with Orbitrap high-resolution mass spectrometry.Among the 56 identified metabolites,the levels of eight metabolites increased and three ones decreased in the first trimester,the concentration of one metabolite increased and those of 20 decreased in the second trimester,as well as the levels of five metabolites increased and two decreased in the third trimester.After false discovery rate correction,the levels of valine and 5-acetamidovalerate in GDM group significantly increased in the first trimester,the levels of 1-methylguanine and 1,3-dihydro-(2 H)-indol-2-one significantly decreased in the second trimester and three metabolites(threonine,OH-octanedioyl-carnitine and pimelylcarnitine)increased and N-acetyltryptophan decreased in the third trimester,respectively.Six metabolites,such as pantothenic acid and threonine,had significant interaction effects between gestational stage(different trimester)and group(GDM or control).The differential metabolites were involved in“tryptophan metabolism”,“purine metabolism”,“valine,leucine and isoleucine degradation”and other pathways.The findings may provide insights into further pathogenesis study of GDM. | Hongzhi Zhao Yuanyuan Zheng Lin Zhu Li Xiang Shunqing Xu Zongwei Cai | 2022 | Chinese Chemical Letters2022，33，6： | 2 |
| 15 | Apoptosis induced by titanium dioxide nanoparticles in cultured murine microglia N9 cells显示文摘Owing to the rapidly increasing output of nano-scale titanium dioxide(TiO2) particles,their potential risk for central nerve system(CNS) has elicited much concern recently.Microglia is the resident macrophage in CNS and essential for the homeostasis of the CNS microenvironment.They are supposed to response to nanoparticles depositing in the brain tissues.Therefore,we investigated the cytotoxic effects of TiO2 NPs on microglia N9 cells in vitro.Results of propidium iodide/fluorescein diacetate(PI/FDA) double staining and MTT test clearly showed that TiO2 NPs more efficiently affected the viability of microglia N9 cells.Further Hoechst 33258 staining and flow cytometric analysis proved that nano-scale but not normal scale TiO2 induced apoptosis in vitro.These data suggest that TiO2 NPs can elicit apoptosis of N9 cells in vitro and thus present a potential risk for CNS. | LI XiaoBo XU ShunQing ZHANG ZhiRen Hermann J Schluesener | 2009 | Chinese Science Bulletin2009，54，20： | 2 |
| 16 | Cold chain and severe acute respiratory syndrome coronavirus 2 transmission:a review for challenges and coping strategies显示文摘Since June 2020,the re-emergence of coronavirus disease 2019(COVID-19)epidemics in parts of China was linked to the cold chain,which attracted extensive attention and heated discussions from the public.According to the typical characteristics of these epidemics,we speculated a possible route of transmission from cold chain to human.A series of factors in the supply chain contributed to the epidemics if the cold chain were contaminated by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),such as temperature,humidity,personal hygiene/protection,and disinfection.The workers who worked in the cold chain at the receiving end faced a higher risk of being infected when they were not well protected.Facing the difficult situation,China put forward targeted and powerful countermeasures to block the cold chain-related risk.However,in the context of the unstable pandemic situation globally,the risk of the cold chain needs to be recognized and evaluated seriously.Hence,in this review,we reviewed the cold chain-related epidemics in China,analyzed the possible mechanisms,introduced the Chinese experience,and suggested coping strategies for the global epidemic prevention and control. | Jiangtao Liu Tongzhang Zheng Wei Xia Shunqing Xu Yuanyuan Li | 2022 | Medical Review2022，2，1： | 2 |
