When studying on the supervision on listed company performance manipulation, the administrator's role has been emphasized increasingly. By setting up a game model, the article analyzes the performance manipulation made by the listed company's administrator. The analysis shows that the optimal performance manipulation strategy taken by the administrator is determined by the profits obtained by China Securities Regulatory Commission (CSRC) and the prior probability of the listed company performance categories made by CSRC, while the optimal supervision strategy taken by CSRC is determined by the final profits of the listed company. Thus, it is obvious that there is a mutual guessing and influencing relationship between the listed company's administrator and CSRC. Finally, the game model constructed is further analyzed by employing it in the real cases. 相似文献

The stability of rock-mass slopes is a very complicated system which is controlled by lots of factors. It is always a very important research subject to evaluate the slope stability reasonably through some evaluation methods. Based on matter-element theory and dependent function,the extension theory is applied to evaluate the stability of rock mass slope,and the extension method for the stability of rock mass slopes is proposed. Taking a real slope project for example,based on the reasonable selection of evaluation factors of slope stability,an extension model for evaluation of slope stability is built,whose result is contrasted with the fuzzy evaluating one. As a result, it is practical and feasible to apply the extension method to estimate the rock slope stability. 相似文献

In this paper, the model of the maximum utility of profit margin of commercial banks under the credit risk and the interest risk is reformulated with full consideration of the profile of the losses of bad debts for the commercial banks. The influence of the requirement in the capital adequacy by the central bank to the commercial banks on bank's yields is studied.Analysis shows that considering the risk loss and risk cost of the commercial bank,enhancing the capital adequacy to commercial bank will increase margin profit of commercial bank with decreasing absolute risk avoidance under the Ross concep. 相似文献

The application of non-linear load produces a mass of harmonics. The AC voltage meter and the AC current meter used in power system are usually rectifying instruments, which adopt principle of responding to the average value of voltage and current and get the virtual value by using of the proportion between the average value and it. Because they are designed based on the 50 Hz standard sinuous wave, the principle error will occur when the voltageof power system and the current of loads include harmonic. Based on their working principle, this kind of error is analyzed quantificationally. And the result shows that it can not be neglected. The voltage and current meters with real virtual value are proposed. 相似文献

With the attention to the comfort degree of living environment, the phenomenon of making use of the PMV -PPD index within the ISO7730 standard to evaluate the indoor thermal comfort degree is more and more widespread. Many papers about indoor thermal environment are based on the PMV - PPD index as the reference or basis to research and analyze. But few people understand and pay attention to the application range of the PMV - PPD index. So some people misuse and abuse the PMV index and deduce some inaccurate conclusions. In this thesis, based on the analysis of the process of deducing PMV equation, the phenomenon that PMV index is different from the fact in the high temperature condition is explained; furthermore the application range of the PMV equation is confirmed. So to obtain the scientific and reasonable evaluation and conclusion in the process of research of the thermal comfort degree can be ensured. 相似文献

The number of underdetermined equation, which is limited by the grounding down lines, reduces the grounding grid corrosion diagnostic precision. Based on the grounding grid fault diagnosis method and sensitivity analysis, the value of slip resistance change on the impact of the port resistance in several cases, such as small span, large span and edge, center and symmetrical cross line of the grounding grid, is analyzed. A new method which is used to select the node pairs to calculate the corrosion situation of grounding grid is presented. Based on this method, the simulation analysis and field test has been done. The experimental results show that this method could improve the accuracy and efficiency of grounding grid fault diagnosis. 相似文献

From the space V 0 , the scaling function of it is found. It is possible to transform the frame of V 0 into Riesz base of it (of course, the orthogonal bases are also Riesz bases),so that the irregular sampling theorem on the frame is changed into the one on the Riesz bases, in other words, the irregular sampling theorem on the Riesz bases is extend onto the frame. The irregular theorem on the frame can be used to the signal process. 相似文献

By analyzing the problems and their reasons existed in the water firing prevention system, it is pointed out that the current Chinese firing prevention system is a partial and half-baked one, based solely on the individual building. Fire is an accident to a building, while it is a necessity to a city. Fire fighting is not only the responsibility of individual buildings, but also a part of disaster prevention system. The specialized management, power of fire fighting and salvation of the city nowadays should be reinforced. The responsibility of firing prevention system in a building is to put off the initial flame and prevent the fire extending within the right time, meanwhile to start the fire prevention and contingency measurements of the city. 相似文献
