With the increasingly economic competition in the World, the audit industry, numerous investors and the enterprises pay more and more attention on the audit of company's sustainable operation. In view of existing situation that the audit on the capacity of sustainable operation attach main importance to the finance of the audited company, in the result, it is difficult to recognize it completely. The model of the balanced scorecard is used, an indicator system that combine company's finance condition and non-finance condition is built in the sustainable operation audit. Basing on the way to process non-dimensional quantities of indicators, the audit use the analytic hierarchy process to determine the weights of the evaluating indicators and take the degree of gray incidence as the evaluation criteria. 相似文献

System of the Geothermal Water in the Nanwenquan Anticline 总被引:1,自引:0,他引:1
In order to exploit and protect the geothermal water scientifically, the chemistry and isotope of geothermal water are studied in Nanwenquan anticline. It is show that the geothermal water comes from atmosphere precipitation in the north of Tongluoxia anticline, in which the Tongluoxia anticline and Nanwenquan anticline are whole geothermal water system. The geothermal water flows from north to south. The geothermal water has hydraulic contact from north to south, from the western limb to eastern limb. The geothermal waters in Nanwenquan anticline are whole geothermal water system. Every exploration of the geothermal water in Nanwenquan anticline should layout. So it can avoid that the yield is higher than pondage, and the geothermal water source environment is destroyed. The study provides theoretical gist for exploiting and utilizing rationally and protecting geothermal water resource effectively. 相似文献

Though the Flood-Control-Projects along Yantze River and Jialing River in Chongqing may well improve the urban traffic and construction,it may change the river hydrodynamic characters.There may be two consequences,one is to reduce the size of cross section and the other is to change the river shape,such as the curvature radius.The phenomena of the local backwater and velocity variety are obvious,which result in some problems for the navigation: sediment,transport and so on.In this paper, the study object is the Flood-Control-Projects and Yangtse River and Jialing River,and the aim is to study the influence of the Flood-Control-Projects on the hydrodynamic state of the two rivers.Using the numerical technique,with the two rivers hydrodynamic model the flow field's change of river after completion of Flood-Control-Projects is simulated and the reasons caused by the change are analyzed. 相似文献

Based on monitoring data of water quality and river runoff from 2007 to 2008, the dynamics of TN and TP transported into the backwater region of the Linjiang River were investigated and fluxes of TN and TP were also estimated. It was shown that the dynamic changes of TN and TP were significant. The concentration of TP in rainy seasons was higher than that in dry seasons, while the cases for TN was contrary. The fluxes of TN and TP were significantly higher in rainy seasons than those in dry seasons. On average, there were about 4 142 t TN and 455 t TP transported into the backwater region of the Linjiang River every year. And TN flux decreased by 32.7% from 2007 to 2008, while TP flux increased by 34.3%, which was in agreement with the inter annual variation of the concentrations of TN and TP. TN flux was primarily influenced by river runoff, whereas TP flux was affected by both concentration and runoff. Further analyses indicated that TN was mainly caused by point source pollutants(dominated by NH3N, and then DON). On the contrary, TP was mainly caused by plane source pollutants(dominated by PO34P). It was also indicated that it was critical to control the point source pollution in the basin to promote the water quality of the backwater region of the Linjiang River. 相似文献

In the strategic cooperation, relative status of the two partners which joined together by the covenant has a great impact on the finally profit distribution. It is analyzed by game theory in this paper that the influence of exterior cooperative opportunities upon the status of a firm when the firm join in an alliance. We focus on the great impact, which is produced by the chance to cooperate with the others that belong separately to the two firms in a strategic cooperation, on the status and profit distribution of the two parts. It is found that a firm will possessed a powerful status in an alliance and carve up more profits from the alliance when it has more opportunities for cooperating. The status differences between the cooperative partners can be better described when a firm sets up a strategic cooperation by combining the method The former researches are done which inspect the inner factors, such as the degree of firms being eager to join an alliance. 相似文献

The Kalman filter algorithms can not solve the problem of the time-frequency localization, and it often switches between the low-frequency filter and high-frequency filter by the mobile detector (The changeable dimension filter algorithms) or Markovian transfer probability matrix (VD algorithms), so it has delay and some influence of the the mobile detector and Markovian transfer probability matrix. Hence, the filter error of the Kalman filter algorithms is obviously big. This paper brings the new mixed filter algorithms (WK algorithms) of the 2D Wavelet transform and Kalman Filter, which has the characteristics of the well time-frequency localization and real-time. The WK algorithms is used to process the radar information and makes the filter estimated data to approach the true track. 相似文献
