Detailed Inventory Mapping and Spatial Analyses to Landslides Induced by the 2013 Ms 6.6 Minxian Earthquake of China

引用

Journal of Earth Science 2016年第6期27卷 1016-1026页

作者： Yingying Tian chong Xu Xiwei Xu jian Chen Key Laboratory of Active Tectonics and Volcano Institute of GeologyChina Earthquake Administration School of Engineering and Technology China University of Geosciences

On July 22, 2013, an earthquake （Ms 6.6） occurred in Minxian, Gansu Province of China, causing a large number of landslides. Based on high resolution remote sensing images before and after this event, we made the visual interpretation to these coseismic landslides, and prepared a detailed inventory. The inventory registers totally 6 478 landslides in the study area. Of them, 3 322 landslides are larger than 100 m2. Based on 5 m resolution DEM, these landslides were used to perform spatial analyses using landslide number density （LND） and landslide area percentage （LAP）. The results show that the highest LND and LAP values are in the elevation range of 2 300-2 500 m and steeper slopes. Slopes facing E, SE, S and SW directions, slopes with larger absolute curvature values, ridges, scopes of gravel beds of Late Pleistocene （Qp） and the VIII-degree seismic intensity are more prone to sliding with high LND and LAP values. The largest LND and LAP values are in the scopes of 0.08 and 0.24 g, respectively. According to landslide distribution, we infer that F2-2 branch of lintan-Dangchang fault is the seismogenic fault. With the increasing distances to this branch fault and drainages, LND and LAP values tend to decrease.

The potential of pervaporation for biofuel recovery from fermentation:An energy consumption point of view

引用

Chinese Journal of Chemical Engineering 2019年第6期27卷 1296-1306页

作者： Peiyao Zheng chong li NaixinWang Jie li Quanfu An MOE Key Laboratory of Macromolecular Synthesis and Functionalization Department of Polymer Science&EngineeringZhejiang UniversityHangzhou 310027China Beijing Key Laboratory for Green Catalysis and Separation College of Environmental and Energy EngineeringBeijing University of TechnologyBeijing 100124China

Recovering alcohols from dilute fermentation broth is an emergent task in bio-fuel production process. Since they are primary planned for fuels, energy required to separate these alcohols should be considered in evaluating the potential of a separation technology. A membrane-based process, pervaporation, is of special interest because of its environmental friendliness and easy integrating character. This review probes into the fundamentals of pervaporation especially in terms of the heat required for evaporation. Meanwhile, the separation data of the most representative alcohol-selective pervaporation membranes reported in the literatures are collected and compared with the vapor–liquid equilibrium curve, which represents the distillation selectivity. They include:inorganic membranes, silicon rubber based membranes, Mixed Matrix Membranes and some other special materials. By doing so, the status of alcohol recovery via pervaporation would be more clear for *** ethanol recovery, it is selectivity rather than flux that is in urgent need of solution. While for butanol recovery,membranes with satisfactory selectivity have been developed, increasing the separation capacity would be more pressing.

Dear Editor,This letter focuses on the node localization problem in underwater acoustic sensor networks(UWASNs) with the time-dependent property and various noise disturbances. A range-based localization scheme aided with an integral-feedback-based neurodynamics(IND)model is proposed and referred to as IND-RS, which has the stability against the internal perturbations encountered during the solving process.

Simulation of municipal solid waste gasification for syngas production in fixed bed reactors

引用

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2010年第8期11卷 619-628页

作者： chong CHEN Yu-qi JIN jian-hua YAN Yong CHI State Key Laboratory of Clean Energy Utilization Zhejiang University Hangzhou 310027 China

This study proposes a model of syngas production from municipal solid waste (MSW) gasification with air in fixed bed reactors. The model (using Aspen plus simulator) is used to predict the results of MSW gasification and to provide some process fundamentals concerning syngas production from MSW gasification. The effects of gasification temperature, air equiva- lence ratio and moisture concentration on the composition of syngas, lower heating value (LHV) of syngas, heat conversion efficiency, and carbon conversion are discussed. The results indicate that higher temperature improves gasification, and higher air equivalence ratio increases the carbon conversion while decreasing syngas LHV. Heat conversion efficiency increases and reaches the maximum and then decreases with the increase of air equivalence ratio. Higher moisture concentration increases the carbon conversion and increases the heat conversion efficiency at lower ratios. Higher temperature and a lower equivalence ratio are favorable for obtaining a higher LHV of syngas at the same moisture concentration.

The BCQ and the Abadie CQ for infinite systems of convex inequalities in Banach spaces are characterized in terms of the upper semi-continuity of the convex cones generated by the subdifferentials of active convex functions. Some relationships with other constraint qualifications such as the CPLV and the Slate condition are also studied. Applications in best approximation theory are provided.

Spectrofluorimetric Determination of Trace Amounts of Gallium with Salicylaldehyde Benzoylhydrazone

引用

Chemical Research in Chinese Universities 1998年第3期14卷 37-41页

作者： TANG Bo WU Chang ju WANG Hong jian YEN jian chong Department of Chemistry Shandong Normal UniversityJinan250014

The fluorescent reagent salicylaldehyde benzoylhydrazone(SABH) was synthesized and its ionization constants were estimated spectrophotometrically. The fluorescent reaction of this reagent with gallium was studied. Based on this chelation reaction, a spectrofluorimetric method was developed for the determination of gallium in a water medium at pH 3.2. Under these conditions, the Ga SABH complex has excitation and emission maxima at 372 and 455 nm, respectively. The linear range of the method was 0～150 μg/L and the detection limit was 0.36 μg/L of gallium when a standard addition method was used in the assay. The molar ratio of gallium to the reagent was 1∶3. The interference of other ions was studied. The extraction with n butyl acetate from a 6 mol/L hydrochloric acid medium was used to separate Ga from the interfering elements in semiconductor silicon and geological samples, and themethod has been successfully applied to the determination of gallium in these samples.

National Science Review 2024年第8期11卷 48-49页

作者： Siran li chong liu Hao Ni School of Mathematical Sciences Shanghai Jiao Tong University Institute of Mathematical Sciences Shanghai Tech University Department of Mathematics University College London

Partial differential equations (PDEs) play a fundamental role in the modelling and analysis of a wide range of physical and geometric problems. Numerous numerical techniques, classical and new, have been proposed to approximate PDE solutions, aiming at attaining high accuracy and efficiency. Most recently, by utilising deep neural networks to represent PDE solutions, machine learning(ML) methods have emerged as a revolutionary tool that demonstrates enormous potential to overcome the curse of dimensionality and to deal with complex geometries.
