2Formation and influencing factors of carbonate source rock of the Lower Permian Chihsia Formation in Chaohu region, Anhui Province显示文摘Highly-mature carbonate source rock is essential to the exploration of oil and gas in southern China. In this study, the carbonate strata in the relatively well-developed Lower Permian Chihsia Formation (located in Chaohu, Lower Yangtze) were targeted, and the formation and influencing factors of source rock were discussed based on paleoenvironment reconstruction using comprehensive sedimentology, palynofacies, and organic geochemistry data. The results demonstrate that the Chihsia Formation is oxygen-deficient biogenic carbonate sediments, with marked variations in the organic and inorganic components, formed during a period of Permian transgression. The formation of source rock is the combined result of high bioproductivity and oxygen-deficient environment generated by transgression and oxygenation events which frequently occurred during transgression periods. Source rock was affected by self-dilution effects and diagenesis, causing its heterogeneous distribution in many intervals. Source rock is over 40 m thick, and can be identified based on its different organic, biological, and mineral composition characteristics. The carbonate rock appears to require no specific clay content in order to become a source rock. The combination of sedimentology, palynofacies, and organic geochemistry has provided an effective means for evaluating and predicting high-maturity carbonate source rock in the region.LIU Feng CAI JinGong LU BingQuan XU JinLi 2011Science China Earth Sciences2011,54,12:7
3AUTOMATIC TEXT SUMMARIZATION BASED ON TEXTUAL COHESION显示文摘This paper presents two different algorithms that derive the cohesion structure in the form of lexical chains from two kinds of language resources HowNet and TongYiCiCiLin. The re-search that connects the cohesion structure of a text to the derivation of its summary is displayed. A novel model of automatic text summarization is devised,based on the data provided by lexical chains from original texts. Moreover,the construction rules of lexical chains are modified accord-ing to characteristics of the knowledge database in order to be more suitable for Chinese summa-rization. Evaluation results show that high quality indicative summaries are produced from Chi-nese texts.Chen Yanmin Liu Bingquan Wang Xiaolong 2007Journal of Electronics(China)2007,24,3:6

5Characteristics of the island-arc pillow lavas from southeast Yunnan Province, and its tectonic implications for Paleo-Tethys in South China显示文摘Based on the geological mapping, it is suggested that the pillow lavas exposed in Jianshui area in southeastern Yunnan Province are emplaced into the western part of Shizong-Mile faults, the boundary between the Yangtze and Cathaysian blocks, and mainly composed of tectonic massive of basalts and basaltic andsites. The geological and geochemical studies show that these lavas erupted in an island arc tectonic setting, which suggests that there existed the subduction of oceanic crust between the Yangtze and Cathaysian blocks. The paleontological fossils in the sedimentary interlayers between the volcanic rocks indicate that these pillow lavas erupted during Carboniferous-Permian. The geologic and geochemical evidence suggested that there existed an eastern branch of Paleo-Tethys between the Yangtze and Cathaysian blocks in southeastern Yunnan, South China.Yunpeng Dong Bingquan Zhu 2000Chinese Science Bulletin2000,45,8:5
6Relation of Isotope Geochemical Steep Zones with Geophysical Fields and Tectonics in the Junction Area of the Cathaysian,Yangtze and Indochina Plates显示文摘Through lead isotope geochemical mapping in the Yunnan-Guizhou area geochemical steep zones (GSZ) have been established, which clearly reveal the junction relationship of the Cathaysian, Yangtze and Indo-China plates. GSZ are closey related to gravity Mono gradient zones and lithospheric thickness. The GSZ between the Yangtze and Cathaysian plates is consistent with the Shizong-Mile tectonic belt, where island arc basalts are well developed. The Yangtze-Indo-China GSZ is parallel to the Jingdong-Mojiang volcanic belt in rift-island arc environments. The evidence of geology, geophysics and geochemistry all indicates that Cathaysia was subducted towards the Yangtze plate and that the Yangtze plate was underthrust beneath the Indo-China, which took place from the Early Carboniferous to the Early Triassic.ZHU Bingquan Dong Yunpeng CHANG Xiangyang ZHANG Zhengwei 2000Acta Geologica Sinica(English Edition)2000,74,2:5
7Lead Isotopic Steep-Dipping Zone and Mineralization—An Example from Mineral Deposits Concentrated Area in East Qinling,China显示文摘Lead isotopic geochemical steep-dipping zone usually exists on inhomogeneous boundaries of earth blocks. Its crossing with the geophysical gradient zone often convergently occurs at giant deposits. Deep structures or concealed structural planes obviously have the coupling relationship with the convergent area of mineral deposits. The geochemical steep-dipping zone is usually distributed along the boundary of ancient continental blocks. Its crossing effect with geophysical gradient zone is usually presented as depression or swell of Moho discontinuity on the crossing direction with the ancient continental margin, which would lead to form deep fractures of earth crust at block margins or lead to adjustment of earth crust texture. The deep hydrothermal liquid would rise up along the structural planes to form the convergent areas of mineral deposits. For example, Luonan- Luanchuan area in east Qinling is a typical crossed area of the geochemical steepdipping zone and geophysical gradient zone. The mineral deposit belt extends along EW direction. It was controlled by the geochemical steepdipping zone equidistantly distributed along NE direction like a string of beads controlled by a gravity gradient zone in NE direction and a mantle depression slope. Along a plunging mantle syncline on EW plunging direction, from the east to the west, checkform was distributed which controls synergic crustmantle granoporphyry rocks. Therefore, a convergent mineralization area of Mo, W, Zn and Au giant deposits occurred.Zhang Zhengwei Zhu Bingquan Guangzhou Institute of Geochemistry, China Academy of Science, Guangzhou 510640 Cai Keqin Deng Jun Department of Earth and Mineral Resources, China University of Geosciences, Beijing 100083 Wang Wei Qiang Lizhi Henan 2000Journal of Earth Science2000,19,1:5
8Facile fabrication of micro-grooves based photonic crystals towards anisotropic angle-independent structural colors and polarized multiple reflections显示文摘In nature,many living organisms exhibit low-angle-dependent or even angle-independent structural colors for wide viewing angle,such as the blue skin of mandrill,feather of blue bird and shell of longhorn beetle,etc.To mimic these structural colors,based on periodic semicircular micro-grooved(PSMG) substrate,silica colloidal photonic crystals provide anisotropic angle-independent structural colors.The PSMG photonic crystals were fabricated by self-assembling monodispersed silica nanoparticles on a micro-grooved template,which can be easily prepared in large scale by a hot embossing method,and no additional materials are needed in the whole preparation process.The PSMG photonic crystals exhibit identical structural colors around the groove axis,whereas it is angle-dependent along the groove axis.In addition,this PSMG surface of photonic crystal also leads to color separation effect and monocolor polarization conversion.This system provides a facile and scalable means to prepare anisotropically angleindependent colloidal photonic crystal,which is considered important in applications in the field of anti-counterfeiting or the manufacture of monochromatic light reflector with wide viewing angles and other novel optical devices.Chuanyong Liu Yue Long Bingquan Yang Guoqiang Yang Chen-Ho Tung Kai Song 2017Science Bulletin2017,62,13:5

10Thermodynamic and economic analyses of a coal and biomass indirect coupling power generation system显示文摘The coal and biomass coupling power genera-tion technology is considered as a promising technology for energy conservation and emission reduction.In this paper,a novel coal and biomass indirect coupling system is proposed based on the technology of biomass gasification and co-combustion of coal and gasification gas.For the sake of comparison,a coal and biomass direct coupling system is also introduced based on the technology of co-combustion of coal and biomass.The process of the direct and the indirect coupling system is simulated.The thermodynamic and economic performances of two systems are analyzed and compared.The simulation indicates that the thermodynamic performance of the indirect coupling system is slightly worse,but the economic performance is better than that of the direct coupling system.When the blending ratio of biomass is 20%,the energy and exergy fficiencies of the indirect coupling system are 42.70%and 41.14%,the intemal rate of returm(IRR)and discounted payback period(DPP)of the system are 25.68%and 8.56 years.The price fluctuation of fuels and products has a great influence on the economic performance of the indirect coupling system.The environmental impact analysis indicates that the indirect coupling system can inhibit the propagation of NOx and reduce the environmental cost.Buqing YE Rui ZHANG Jin CAO Bingquan SHI Xun ZHOU Dong LIU 2020Frontiers in Energy2020,14,3:3

12COMBINING FEATURE SCALING ESTIMATION WITH SVM CLASSIFIER DESIGN USING GA APPROACH显示文摘This letter adopts a GA (Genetic Algorithm) approach to assist in learning scaling of features that are most favorable to SVM (Support Vector Machines) classifier, which is named as GA-SVM. The relevant coefficients of various features to the classification task, measured by real-valued scaling, are estimated efficiently by using GA. And GA exploits heavy-bias operator to promote sparsity in the scaling of features. There are many potential benefits of this method:Feature selection is performed by eliminating irrelevant features whose scaling is zero, an SVM classifier that has enhanced generalization ability can be learned simultaneously. Experimental comparisons using original SVM and GA-SVM demonstrate both economical feature selection and excellent classification accuracy on junk e-mail recognition problem and Internet ad recognition problem. The experimental results show that comparing with original SVM classifier, the number of support vector decreases significantly and better classification results are achieved based on GA-SVM. It also demonstrates that GA can provide a simple, general, and powerful framework for tuning parameters in optimal problem, which directly improves the recognition performance and recognition rate of SVM.Yu Ying Wang Xiaolong Liu Bingquan 2005Journal of Electronics(China)2005,22,5:2
13Rapid determination of histamine concentration in fish(Miichthys Miiuy)by surface-enhanced Raman spectroscopy and density functional theory显示文摘Histamine is a type of biogenic amine,which plays a major role in the health problems associated with seafood consumption.Legislative limits of histamine level in seafood have been set in many countries.This study focuses on investigating the feasibility and potentiality of determining histamine concentration in fish(Miichthys miiuy)by surface-enhanced Raman spectroscopy(SERS)combined with density functional theory(DFT).Both a gold colloid and a silver colloid were used to determine the enhancement effect for SERS detection of histamine standard solution,and the gold colloid exhibited more effective as compared to the silver colloid.The protocol on extraction of histamine with 12%trichloroacetic acid and adjustment of pH with NaOH solution(5 mol/L)could significantly shorten sample preparation(20 min)and provide clear SERS spectra of histamine.The peaks of histamine molecules were classified using the DFT and five spectra(953 cm^(-1),992 cm^(-1),1106 cm^(-1),1262 cm^(-1)and 1317 cm^(-1))were selected as the characteristic bands of histamine discrimination.Moreover,the intensity of the peak at 1262 cm^(-1)had a good linear relationship with histamine concentration at 5-400 mg/kg with R^(2)=0.9755.It is concluded that the SERS-DFT approach will be a potential method for rapidly and reliably detecting histamine at levels from 5 mg/kg to 400 mg/kg in fresh fish.Chu Bingquan Lin Lei He Yong 2017International Journal of Agricultural and Biological Engineering2017,10,4:2

16Detection of ECTV,MHV and SV in Clean-grade Mice and Rats in East China显示文摘To study the epidemic status of Ectromelia virus( ECTV),Mouse hepatitis virus( MHV) and Sendai virus( SV) in clean-grade experimental mice and rats in East China,30 individuals of ICR and/or C57BL/6 mice and 15 individuals of SD or Wistar rats were purchased from four major experimental animal supply bases in East China. Blood samples were collected by eyeball picking method,and serum was separated. ECTV,MHV and SV serum antibodies in mice were detected using imported commercial ELISA kits. Since rats were not easily infected by MHV and SV,only the ECTV serum antibody was detected in rats. Survey results revealed that clean-grade experimental mice and rats derived from three out of four major experimental animal supply bases were negative in detection,but the positive rates of MHV and SV serum antibody in clean-grade ICR mice in one supply base were 56. 7% and 100. 0%,respectively,while the positive rate of MHV serum antibody in C57BL/6 mice was 100%. Research results showed that most of the commercial experimental mice and rats in major experimental animal supply bases in East China were qualified in detection of above three kinds of diseases,but MHV and SV still existed in individual base,with severe infection status.Thus,active measures must be strengthened to purify mice and rats. Meanwhile,monitoring of mouse and rat diseases must be developed seriously to guarantee the quality of experimental mice and rats,so as to avoid adverse impacts on breeding and use of experimental rats and mice.Song Hongyan Dong Ronglian Qiu Baofeng Jing Jin Gu Bingquan Shao Yixiang Liu Chun Zhu Shunxing Wu Liucheng 2017Animal Husbandry and Feed Science2017,9,1:1

19RESEARCH OF PINYIN-TO-CHARACTER CONVERSION BASED ON MAXIMUM ENTROPY MODEL显示文摘This paper applied Maximum Entropy (ME) model to Pinyin-To-Character (PTC) conversion in-stead of Hidden Markov Model (HMM) that could not include complicated and long-distance lexical informa-tion. Two ME models were built based on simple and complex templates respectively, and the complex one gave better conversion result. Furthermore, conversion trigger pair of y A → y B cBwas proposed to extract the long-distance constrain feature from the corpus; and then Average Mutual Information (AMI) was used to se-lect conversion trigger pair features which were added to the ME model. The experiment shows that conver-sion error of the ME with conversion trigger pairs is reduced by 4% on a small training corpus, comparing with HMM smoothed by absolute smoothing.Zhao Yan Wang Xiaolong Liu Bingquan Guan Yi 2006Journal of Electronics(China)2006,23,6:1
