| 2 | Estimation of LISS(local input-to-state stability) properties for nonlinear systems显示文摘Compared with input-to-state stability(ISS) in global version,the concept of local input-to-state stability(LISS) is more relevant and meaningful in practice.The key of assessing LISS properties lies in investigating three main ingredients,the local region of initial states,the local region of external inputs and the asymptotic gain.It is the objective of this paper to propose a numerical algorithm for estimating LISS properties on the theoretical foundation of quadratic form LISS-Lyapunov function.Given developments of linear matrix inequality(LMI) methods,this algorithm is effective and powerful.A typical power electronics based system with common DC bus is served as a demonstration for quantitative results. | WU ShengYu,MEI ShengWei & ZHANG XueMin State Key Laboratory of Power Systems,Department of Electrical Engineering,Tsinghua University,Beijing 100084,China | 2010 | Science China(Technological Sciences)2010，53，4： | 13 |

| 5 | Crop Classification Using MODIS NDVI Data Denoised by Wavelet: A Case Study in Hebei Plain, China显示文摘Time-series Moderate Resolution Imaging Spectroradiometer (MODIS) Normalized Difference Vegetation Index (NDVI) data have been widely used for large area crop mapping.However,the temporal crop signatures generated from these data were always accompanied by noise.In this study,a denoising method combined with Time series Inverse Distance Weighted (T-IDW) interpolating and Discrete Wavelet Transform (DWT) was presented.The detail crop planting patterns in Hebei Plain,China were classified using denoised time-series MODIS NDVI data at 250 m resolution.The denoising approach improved original MODIS NDVI product significantly in several periods,which may affect the accuracy of classification.The MODIS NDVI-derived crop map of the Hebei Plain achieved satisfactory classification accuracies through validation with field observation,statistical data and high resolution image.The field investigation accuracy was 85% at pixel level.At county-level,for winter wheat,there is relatively more significant correlation between the estimated area derived from satellite data with noise reduction and the statistical area (R2 = 0.814,p < 0.01).Moreover,the MODIS-derived crop patterns were highly consistent with the map generated by high resolution Landsat image in the same period.The overall accuracy achieved 91.01%.The results indicate that the method combining T-IDW and DWT can provide a gain in time-series MODIS NDVI data noise reduction and crop classification. | ZHANG Shengwei LEI Yuping WANG Liping LI Hongjun ZHAO Hongbin | 2011 | Chinese Geographical Science2011，21，3： | 9 |
| 6 | Advanced EMS and its trial operation in Shanghai power system显示文摘To meet the demand of high stability,high quality,and low losses of power systems,the advanced energy management system (AEMS) is established and revealed in this bulletin,which has been put into trial operation in Shanghai power system for almost half a year. The AEMS is novel from all aspects covering idea,theory,method,software,and engineering. The essence of AEMS is exercising the hybrid automatic control theory and technology to realize multi-objective optimal closed-loop control of power systems. Based on an 'event-driven' strategy,the AEMS transforms multi-objective optimal control problems into event identification and elimination by defining the unsatisfactory states of a power system as events. This bulletin concisely presents the theory and main advantages of AEMS,as well as its implementation in Shanghai power system. | LU Qiang HE GuangYu MEI ShengWei SUN YingYun RUAN QianTu WANG Wei ZHANG WangJun YU XuFeng | 2008 | Science China(Technological Sciences)2008，51，2： | 9 |
| 7 | Isolation,Screening,and Optimization of the Fermentation Conditions of Highly Cellulolytic Bacteria from the Hindgut of Holotrichia parallela Larvae(Coleoptera:Scarabaeidae)显示文摘From the hindgut contents of Holotrichia parallela larvae,207 aerobic and facultatively anaerobic cellulolytic bacterial isolates were obtained.These bacterial isolates were assigned to 21 genotypes by amplified ribosomal DNA restriction analysis(ARDRA).A partial 16 S rDNA sequence analysis and standard biochemical and physiological tests were used for the assignment of the 21 representative isolates.Our results show that the cellulolytic bacterial community is dominated by the Proteobacteria(70.05%),followed by the Actinobacteria(24.15%),the Firmicutes(4.35%),and the Bacteroidetes(1.45%).And among the cellulolytic bacteria,some isolates,Siphonobacter aquaeclarae,Cellulosimicrobium funkei,Citrobacter freundii,Pseudomonas nitroreducens,and so on,are reported to be cellulolytic for the first time in this study.Among these isolates,a novel bacterium,designated Pseudomonas sp.HP207,with the highest endoglucanase productivity was selected for further study.The production of the endoglucanase was optimized by varying various physical culture conditions using a submerged fermentation method.Under the optimized fermentation conditions,the maximum endoglucanase activity of 1.432 U mL-1 in bacterial cultures was obtained,higher than those of the most widely studied bacteria and fungi,which are the attractive candidates for the commercial producer of cellulase.And the crude endoglucanase enzyme was also highly thermostable;approximately 55% of the original activity was maintained after pretreatment at 70°C for 1 h.Thus,from the present study,the bacterium can be added up to the database of cellulolytic bacteria,the scarab gut is an attractive source for the study of novel cellulolytic microorganisms and enzymes useful for cellulose degradation. | Ping Sheng Shengwei Huang Qi Wang Ailing Wang Hongyu Zhang | 2012 | 华中昆虫研究2012，，1： | 7 |
| 8 | Chemical dehydration coupling multi-effect evaporation to treat waste sulfuric acid in titanium dioxide production process显示文摘In order to concentrate the diluted sulfuric acid from the titanium dioxide(TiO2)production of sulphate process,a new concentration process was proposed by coupling chemical dehydration and multi-effect evaporation.The ferrous sulfate monohydrate(FeSO4·H2O),as the dehydrant,was added to the diluted sulfuric acid to form ferrous sulfate heptahydrate(FeSO4·7H2O)according to the H2SO4-FeSO4-H2O phase diagrams,which partially removes the water.This process was named as Chemical Dehydration Process.The residual water was further removed by two-effect evaporation and finally 70 wt%sulfuric acid was obtained.The FeSO4·H2O can be regenerated through drying and dehydration of FeSO4·7H2O.The results show that FeSO4·H2O is the most suitable dehydrant,the optimal reaction time of chemical dehydration process is 30 min,and low temperature is favorable for the dehydration reaction.45.17%of the entire removed water can be removed by chemical dehydration from the diluted sulfuric acid.This chemical dehydration process is also energy efficient with 24.76%saving compared with the direct evaporation process.Furthermore,51.21%of the FeSO4 dissolved originally in the diluted sulfuric acid are precipitated out during the chemical dehydration,which greatly reduces the solid precipitation and effectively alleviates the scaling in the subsequent multi-effect evaporation process. | Hongyin Pang Ruifang Lu Tao Zhang Li Lü Yanxiao Chen Shengwei Tang | 2020 | Chinese Journal of Chemical Engineering2020，28，4： | 7 |
| 9 | Multi-level multi-area hybrid automatic voltage control system and its trial operation in Northeast China Grid显示文摘In order to coordinate automatic voltage control(AVC)systems of a large interconnected system,a multi-level multi-area hybrid automatic voltage control(MLMA-HAVC)system was constructed.This system began its trial operation in the Northeast China Grid in January 2010,and for the first time in China and abroad it realized automatic close-loop control of multi-area and multi-level interconnected power grid and multi-objective self-approaching optimization in aspects of security,high quality and economic operation.This system has three breakthroughs in theory and engineering application:1)Established the MLMA-HAVC theory to solve multi-objective optimization of large-scale system;2)proposed reactive power/voltage coordination control method to inhibit or further eliminate regional oscillations;3)presented advanced state estimation algorithm to guarantee acquisition of high reliability data.This paper summarizes the basic principle of MLMA-HAVC,and reports engineering realization of MLMA-HAVC system in the Northeast China Grid. | ZHANG XueMin MEI ShengWei SU XinYi WANG Gang JIA Wei SHAO GuangHui XU XingWei | 2011 | Science China(Technological Sciences)2011，54，9： | 6 |
| 10 | Noble Gas Isotopic Compositions of Cobalt-rich Ferromanganese Crusts from the Western Pacific Ocean and Their Geological Implications显示文摘Noble gas isotopic compositions of various layers in three-layered (outer, porous and compact layers) cobalt-rich ferromanganese crusts and their basaltic and phosphorite substrates from the western Pacific Ocean were analyzed by using a high vacuum gas mass spectrum. The analytical results show that the noble gases in the Co-rich crusts have derived mainly from the ambient seawater, extraterrestrial grains such as interplanetary dust particles (IDPs) and wind-borne continental dust grains, and locally formation water in the submarine sediments, but different noble gases have different sources. He in the crusts derives predominantly from the extraterrestrial grains, with a negligible amount of radiogenic He from the eolian dust grains. Ar is sourced mainly from the dissolved air in the seawater and insignificantly from radiogenic Ar in the eolian continental dust grains or the formation water. Xe and Ne derive mainly from the seawater, with minor amounts of extraterrestrial Xe and Ne in the IDPs. Compared with the porous and outer layers, the compact layer has a relatively high 4He content and lower 3He/4He ratios, suggesting that marine phosphatization might have greatly modified the noble gas isotopic compositions of the crusts. Besides, the 3He/4He values of the basaltic substrates of the cobalt-rich crusts are very low and their R/Ra ratios are mostly <0.1 Ra, which are similar to that of phosphorite substrates (0.087 Ra), but much lower than that of fresh submarine MORB (8.75±2.14 Ra) or seamount basalts (3-43 Ra), implying that the basaltic substrates have suffered strong water/rock interaction and reacted with radiogenic 4He and P-rich upwelling marine currents during phosphatization. The trace elements released in the basalt/seawater interaction might favor the growth of cobalt-rich crusts. The relatively low 3He/4He values in the seamount basalts may be used as an important exploration criterion for the cobalt-rich ferromanganese crusts. | SUN Xiaoming XUE Ting HE Gaowen YE Xianren ZHANG Mei LU Hongfeng WANG Shengwei | 2007 | Acta Geologica Sinica(English Edition)2007，81，1： | 5 |
| 11 | MCM-36 zeolites tailored with acidic ionic liquid to regulate adsorption properties of isobutane and 1-butene显示文摘Adsorption properties of an adsorbent or a catalyst towards adsorbates are crucial in the process of adsorption separation or catalytic reaction. Surface morphology and structure of adsorbents have a significant impact on the adsorption properties. In this study, a novel acidic ionic liquid, 1-butyl-3-(triethoxysilylpropyl)imidazolium hydrogen sulfate(i.e., [BTPIm][HSO_4]), was synthesized and subsequently grafted onto the MCM-36 zeolite for the regulation of its adsorption properties towards isobutane and 1-butene. The resultant [BTPIm][HSO_4]-immobilized MCM-36(i.e., MCM-36-IL) was characterized by FT-IR, XPS, XRD, SEM, TG/DTG and N_2 adsorption–desorption measurement. It was found that the specific surface area, micropore volume and mesopore volume of the MCM-36 support underwent a reduction upon the immobilization of ionic liquid,while the surface density of acid increased from 0.0014 to 0.0035 mmol·m^(-2). The adsorption capacity of isobutane and 1-butene on the MCM-36-IL was determined by a static volumetric method. Results demonstrated that the interaction between isobutane and MCM-36-IL was enhanced and the interaction between 1-butene and MCM-36-IL was reduced. As a result, a tunable adsorption ratio of isobutane/1-butene on MCM-36 was achieved.With the increase in surface density of acid and the tunable adsorption ratio of isobutane and 1-butene on the functionalized MCM-36, the acidic ionic liquid-immobilized zeolites are beneficial to obtain an improved reaction yield and a prolonged catalyst life in the reactions catalyzed by solid acid. | Hongxia Li Tao Zhang Shaojun Yuan Shengwei Tang | 2016 | Chinese Journal of Chemical Engineering2016，24，12： | 5 |
| 12 | Preparation of mesoporous activated carbons from coal liquefaction residue for methane decomposition显示文摘Mesoporous activated carbons were prepared from direct coal liquefaction residue(CLR)by KOH activation method,and the experiments were carried out to investigate the effects of KOH/CLR ratio,solvent for mixing the CLR and KOH,and carbonization procedure on the resultant carbon texture and catalytic activity for catalytic methane decomposition(CMD).The results showed that optimal KOH/CLR ratio of 2:1; solvent with higher solubility to KOH or the CLR,and an appropriate carbonization procedure are conductive to improving the carbon pore structure and catalytic activity for CMD.The resultant mesoporous carbons show higher and more stable activity than microporous carbons. Additionally,the relationship between the carbon textural properties and the catalytic activity for CMD was also discussed. | Jianbo Zhang Lijun Jin Shengwei Zhu Haoquan Hu | 2012 | Journal of Natural Gas Chemistry2012，21，6： | 5 |
| 13 | An implantable microelectrode array for simultaneous L-glutamate and electrophysiological recordings in vivo显示文摘L-glutamate,the most common excitatory neurotransmitter in the mammalian central nervous system(CNS),is associated with a wide range of neurological diseases.Because neurons in CNS communicate with each other both electrically and chemically,dualmode(electric and chemical)analytical techniques with high spatiotemporal resolution are required to better understand glutamate function in vivo.In the present study,a silicon-based implantable microelectrode array(MEA)composed of both platinum electrochemical and electrophysiological microelectrodes was fabricated using micro-electromechanical system.In the MEA probe,the electrophysiological electrodes have a low impedance of 0.018 MΩat 1 kHz,and the electrochemical electrodes show a sensitivity of 56 pAμM^(−1) to glutamate and have a detection limit of 0.5μM.The MEA probe was used to monitor extracellular glutamate levels,spikes and local field potentials(LFPs)in the striatum of anaesthetised rats.To explore the potential of the MEA probe,the rats were administered to KCl via intraperitoneal injection.K+significantly increases extracellular glutamate levels,LFP low-beta range(12–18 Hz)power and spike firing rates with a similar temporal profile,indicating that the MEA probe is capable of detecting dual-mode neuronal signals.It was concluded that the MEA probe can help reveal mechanisms of neural physiology and pathology in vivo. | Wenjing Wei Yilin Song Li Wang Song Zhang Jinping Luo Shengwei Xu Xinxia Cai | 2015 | Microsystems & Nanoengineering2015，1，1： | 4 |
| 14 | Analysis of the visible fracture system of coalseam in Chengzhuang Coalmine of Jincheng City,Shanxi Province显示文摘In No. 3 coalseam of Chengzhuang Coalmine of Jincheng City, there exists the visible fracture system consisting of joints, gas-expanding fractures and cleats. The gas-expanding fractures develop mainly in the bright coal sub-layer and cleats, in the vitrain and bright coal. The joints fall into two types, one developing in the coalseam and the other cutting through the whole coalseam and entering into the top and bottom rock layer. The development direction of joints is basically similar to that of gas-expanding fractures: NNE and NNW. The formation of the visible fracture system is classified as the stage of the development of cleat fissures in the coalification period, the stage of the full development of cleats and the formation of gas-expanding fractures in the second coalification period and the stage of the formation of joints by structural function. There is the spatial unhomoge-neity in three dimensions for the visible fracture system of the coal seam in Chengzhuang Coalmine: the regular distribution of the visible fractures as groups in the plane and the coal sub-layer with high permeability rate in profile. The research findings of the visible fracture system of coal seam can be applied to the drilling of the coalbed methane and to heightening the let-off efficiency of coalseam gas. | Shengwei Wang Guangjiu Hou Ming Zhang Qinping Sun | 2005 | Chinese Science Bulletin2005，50，S1： | 4 |
| 15 | Numerical simulation of spatial distributions of mining-induced stress and fracture fields for three coal mining layouts显示文摘In this study, the spatial distributions of stress and fracture fields for three typical underground coal mining layouts, i.e. non-pillar mining(NM), top-coal caving mining(TCM) and protective coal-seam mining(PCM), are modeled using discrete element software UDEC. The numerical results show that different mining layouts can lead to different mining-induced stress fields, resulting in diverse fracture fields. For the PCM, the mining influenced area in front of the mining faces is the largest, and the stress concentration factor in front of the mining faces is the lowest. The spatial shapes of the mining-induced fracture fields under NM, TCM and PCM differ, and they are characterized by trapezoidal, triangular and tower shapes, respectively. The fractal dimensions of mining-induced fractures of the three mining layouts decrease in the order of PCM, TCM and NM. It is also shown that the PCM can result in a better gas control effect in coal mines with high outburst potential. The numerical results are expected to provide a basis for understanding of mining-induced gas seepage fields and provide a reference for highefficiency coal mining. | Shengwei Li Mingzhong Gao Xiaojun Yang Ru Zhang Li Ren Zhaopeng Zhang Guo Li Zetian Zhang Jing Xie | 2018 | Journal of Rock Mechanics and Geotechnical Engineering2018，10，5： | 3 |
| 16 | Metagenome analysis reveals potential microbial functions in topsoil of wheat-maize rotation system with five-year application of fertilizers显示文摘Fertilization mode affects soil quality and ecological health.The effects of four fertilization regimens on lignocellulose content,readily degradable carbohydrate decomposition,and potential microbial functions in the topsoil of a wheat-maize rotation system between 2012 and 2017 were investigated.The fertilization regimens of control(control NFNB),high chemical fertilizer(HCF),high biochar plus low chemical fertilizer(HBLCF),and biochar-based fertilizer(BBF)were compared on soil fundamental properties,microbial structure,and potential function in soil carbohydrate degradation based on metagenome analysis.The diversity of carbohydrate-active enzyme genes in the topsoil microbial consortia in the four trials was primarily distributed within the ten ecologically most dominant phyla.Application of BBF was associated with the lowest decline in total nitrogen and P2O5(2012-2017:6.5%and 28.1%,respectively)and the most effective carbohydrate decomposition(2015-2017:67.0%for cellulose and 59.9%for readily degradable carbohydrate).Carbohydrate transport and metabolism accounted for 6.0%of reads assigned functional classification under the BBF regimen.These findings reveal the ecologically functional diversity of topsoil microorganisms and suggest BBF application as a promising strategy for sustainable agriculture and beneficial to soil health. | Yujun Shen Lixin Zhao Haibo Meng Hongsheng Cheng Jingtao Ding Jiarui Wang Shanshan Dong Xi Zhang Liqiu Song Shengwei Zheng | 2019 | International Journal of Agricultural and Biological Engineering2019，12，6： | 3 |

| 19 | Densities and surface tensions of ionic liquids/sulfuric acid binary mixtures显示文摘The densities and surface tensions of [Bmim][TFO]/H_2SO_4, [Hmim][TFO]/H_2SO_4 and [Omim][TFO]/H_2SO_4 binary mixtures were measured by pycnometer and Wilhelmy plate method respectively. The results show that densities and surface tensions of the mixtures decreased monotonously with increasing temperatures and increasing ionic liquid(IL) molar fraction. IL with longer alkyl side-chain length brings a lower density and a smaller surface tension to the ILs/H_2SO_4 binary mixtures. The densities and surface tensions of the mixtures are fitted well by Jouyban–Acree(JAM) model and LWW model respectively. Redlich-Kister(R–K) equation and modified Redlich-Kister(R–K) equation describe the excess molar volumes and excess surface tensions of the mixtures well respectively. Adding a small amount of ILs(xILb 0.1) into sulfuric acid brings an obvious decrease to the density and the surface tension. The results imply that the densities and surface tensions of ILs/H_2SO_4 binary mixtures can be modulated by changing the IL dosage or tailoring the IL structure. | Tao Zhang Jing Hu Shengwei Tang | 2018 | Chinese Journal of Chemical Engineering2018，26，7： | 3 |
| 20 | Transient stability and emergency control显示文摘Comparability of emergency control strategies with different instability modes is the key issue to decide which control strategy to be implemented. This paper considers that the essential factor causing instability should be used to form a unified standard to assess the effectiveness of control strategies with different instability modes. Thus a switching control stabilization principle was proposed based on elimination of the unbalanced energy between mechanical and electrical energies of generator sets. Along this way, the difficulty of seeking a Lyapunov function was circumvented. According to the principle, an emergency control algorithm framework was established to handle transient stability assessment, control location selection and control amount evaluation. Within the framework, this paper studied instability mode transition, then proposed an algorithm based on prediction function and a new approach to normalized stability margin stemmed from static EEAC method, which can increase comparability of various control locations. The simulations on the New-England System verified the proposed emergency control method for stabilizing transient stability. | ZHANG XueMin MEI ShengWei WU ShengYu | 2009 | Science China(Technological Sciences)2009，52，2： | 3 |
