The paper argues that the systematic risk not only affects the investment in securities during times of financial crisis, but also causes losses in daily securities trading. The paper carries out an empirical analysis on the existence of fl coefficient for China＇s listed companies within a period of one year, and examines the impact of systematic risk on the losses of investors. The civil damages of false statements should take full account of the losses arising from systematic risk. After analysis, the paper uses the correlation coefficient to represent the ratio of losses arising from systematic risk of all the transactions of a particular stock during a certain period of time, and tries to develop two methods to measure the damages after adjusting the losses caused by the systematic risk. The paper has a theoretical foundation for the estimation of losses caused by systematic risk, and matches the risks and returns. The result of the paper has provided an effective method of calculation in the determination of reasonable damages in the case of China Langfang Development Co., Ltd.展开更多

The linear cascade consists of the stator blades of the last stage of low pressure steam turbine. The applied experimental test section is a part of a small scale steam power plant located at Silesian Uni- versity of Technology in Gliwice. The steam parameters at the test section inlet correspond to the real conditions in low pressure part of 200MWe steam turbine. The losses in the cascade were estimated using measured static pressure and temperature behind the cascade and the total parameters at inlet. The static pressure measurements on the blade surface as well as the Schlieren pictures were used to assess the flow field in linear cascade of steam turbine stator blades.展开更多

The properties of lithium-ion (Li-ion) battery, such as cycle life, irreversible capacity loss, self-discharge rate, electrode corrosion and safety are usually ascribed to the quality of the SEI, which are highly dependent on the thickness. Thus, understanding the formation mechanism and the SEI thickness is of prime interest. First, we apply dimensional analysis to obtain an explicit relation between the thickness and the number density in this study. Then the SEI thickness in the initial charge-discharge cycle is analyzed and estimated for the first time using the Cahn-Hilliard phase-field model. In addition, the SEI thickness by molecular dynamics simulation validates the theoretical results. It has been shown that the established model and the simulation in this paper estimate the SEI thickness concisely within order-of-magnitude of nanometers. Our results may help in evaluating the performance of SEI and assist the future design of Li-ion battery.展开更多
