Demonstrative study on Company judicial dissolution---On the view of limited company

目前，我国关于公司司法解散的法律法规共有两个：一是现行的《中华人民共和国公司法》第183条；二是由最高人民法院于2008年5月19日颁布实施的《最高人民法院关于适用〈公司法〉若干意见的规定（二）》中的相关规定。但是，这些法律、法规对于法院在审理公司司法解散诉讼案件时的指导还是远远不够的，从而导致在相关案件的审理过程中存在标准不一，执行混乱等情况。随着社会经济的逐步发展，不断完善公司司法解散诉讼等相关法律法规，探索公司司法解散诉讼的操作方式，对于建立和完善社会主义市场经济体制有着十分重要的作用。 2005年公司法修订后，对于设立公司的门槛，尤其是将非一人有限公司的设立金额降至3万元人民币后，各...There are《Company Law of The People of Republic of China 》 and judicial interpretation of《Supreme People's Court is as regards suitable for use some idea regulation of 〈the Company Law〉》 two sections laws as instructions to the people’s courts for hearing the cases of judicial dissolutions.

In situ EIS Study on Titanium/Living Cells Interface

设计了原位电解池用于生物材料/活细胞界面电化学交流阻抗谱(EIS)的测量,原位观测了钛/MG63细胞界面EIS行为及其随时间的变化.原位电解池中引入Ag/AgCl作为参比电极,解决了EIS测量过程中高频部分信号失真的问题.钛/MG63细胞界面EIS研究初步结果表明:活细胞在钛电极表面附着,可改变界面双电层结构和电极的表面状态,进而影响界面的电化学性质.实验发现,由于钛电极表面氧化层的阻抗信号处于中低频段,而细胞膜层自身的电化学阻抗响应位于高频范围,由此,可分别分析不同的电极过程,解析其相互关系,研究活细胞在生物材料表面的作用机理.Using a home-made in situ electrochemical cell of electrochemical impedance spectroscop(EIS), the impedance behaviors of the titanium/MG63 cells interface were measured to elucidate the interfacial structure and to monitor the interactions of biomaterials and living cells in a physiological condition. The in situ electrochemical cell was designed to detect the dynamic EIS behavior of living cells growing on a tiatanium surface. A three-well design of electrochemical cell was used to decrease system error and a home-made Ag/AgCl electrode was introduced as a reference electrode to eliminate the distortion phenomena in high frequency range. The EIS spectra and its time dependency of titanium/MG63 cells interface showed that the polarization resistance was increased with the decreasing of CPE constant (Y0) and a new time constant in high frequency range was detected. It suggested that the adhesion and growth activities of the living cells on the biomaterial surface may influence the surface status and the structure of the double layer at the interface, and thus alter its electrochemical characteristics.国家自然科学基金(20273055);; 教育部博士点基金(20020384012);; 国家863计划(2003AA302230)资助项

Simple Type Phase Detection System Applied on Multimachine Power System during Transient Period

In multimachine power system, there is very difficulty to measure the phase angle between each generators which distance is far away. In this paper, equivalent one machine to infinite bus system is applied and two methods to detect phase angle are showed. The first is equivalent reactance method, in which after the estimation of equivalent reactance of power system, this equivalent reactance is used to detect phase angle swing during transient time. Three models used to detect phase angle are compared concerning the approximation to the true value and the error of equivalent reactance is estimated. This method is effective in low and medium load state conditions. In heavey load state condition, the phase angle swing is largely disturbed by the reaction between generators, so the error in case of using equivalent reactance method is large. The second method based on observer theory with the equivalent reactance method jointly is developed. Equivalent nonlinear generator's model and two type of observed values (active power Pe or angle velocity ω) in the method are used to estimate the phase angle swing of generator. The result is that ω type's feedback has a bigger range than Pe type's feedback concerning feedback gain choosing. The method based on observer using the equivalent reactance has a good result specially in heavey load state condition compared with the first method using equivalent reactance method

Research progress in PAHs degradation genes and enzymes

通讯作者E-mai:l [email protected][中文文摘]由于环境中的多环芳烃(PAHs)具有高遗传毒性和“三致”性(致癌、致畸和致突变),其生物降解基因和降解功能酶研究备受关注。多环芳烃双加氧酶是近年来研究较多的多环芳烃降解的关键酶系之一,主要由细菌产生,可通过氧化反应使多环芳烃开环生成小分子的中间产物并最终氧化成CO2和水。目前,有关这类酶的理化性质、结构特点、功能等的研究相继开展,本文对PAHs降解基因、降解酶的研究现状与发展趋势进行综述。[英文文摘] Polycyclic aromatic hydrocarbons (PAHs) are a group of organic pollutants that accumulated in the environment due to a variety of anthropogenic activities. More and more attention has been paid to PAHs, because of their toxic, carcinogenic and mutagenic potential. The aromatic ring-cleaving enzymes produced by microbes play a definitive role in the metabolism of aromatic compounds. These enzymes can catalyze the addition of two atoms of molecular oxygen directly onto aromatic rings and their derivatives, with subsequent cleavage of aromatic rings. At present, the studies on the physical and chemical properties, molecular structure, and functions of these enzymes are carried on, and this paper reviewed the current status and trend on the research of the genes and enzymes involved in PAHs degradation.国家自然科学基金项目(40576054,40476047);长江学者和创新团队发展计划资助项目(40521003

Effects of alkaline-earth strontium on the performance of Co/Al_2O_3 catalyst for methane partial oxidation
