This paper constructs a model of refrigerant thermodynamic properties calculation for simulation of refrigeration and air condition system based on the parametric equations of state of refrigerant. The Visual C++ 6.0 language is used to develop this model, which has a friendly user interface (UI). This program is easy to learn and use and it has reliably function. Compared with the data provided by the standard graphs and tables of refrigerant thermodynamic properties, the calculation results of this model have certain precision and meet the expectative requirements. 相似文献

A new method of computing the cutter specifications and machine settings for the manufacture of spiral bevel and hypoid gears is studied. And a software system which includes the program models of new and old methods is developed. The system can perform the computations such as blank dimensions,cutting and grinding settings,tooth contact analysis and under cut check of SGM,SFM,SGT,SFT,HGM,HFM,HGT,HFT cutting methods. The new method can allow the user to give the position and length of contact pattern,the direction of contact path and the relative anglar acceleration. The system can be easily operated. 相似文献

In order to implement the security management of management information system (MIS), a target-based security management architecture is proposed. For MIS users, the user interface (UI) is the only way to interact with the MIS system, so all the objects (targets) which need to be managed on UI is registered first, thus for every target the state such as enabled, not enabled, visible, not visible, readonly etc., is assigned. For some users, a set of targets with some state is assigned so that the management granularity in MIS can reach any degree. This approach provides a very flexible way to the security management in MIS. 相似文献

Application system generally refers to all kinds of computer information system. It aims at improving the sharing and application of the resource. The resource in application system usually means data resource. For computer management and maintenance, there are not only data resource, but also program resource and network resource. Effective management of this resource is key to ensure proper work of the application system. In this paper, the basic pattern and policy for resource management is put forward and a method to build and realize the resource layer that lies between database layer and application layer is to be found. This management layer, which skillfully connects the application system with resource and establishes good base for application and exploitation of system, is named as resource management system. 相似文献

Distribution management utilizes the technique of electronics, computer, and automatics to supervise, control, or manage the distribution equipments and user equipments for improving the distribution management. Because the distribution management needs different systems of cooperation and realization of information sharing, realizing inter-application integration is difficult for electrical information system at present. On the background of distribution management system, through the analysis of the principle and character, feasibility of integration for disparate system, such as DMS, is discussed. The analysis results show that the information communication between disparate system, and the decoupling between interfaces and networks are realized by IEC61968. So it is feasible to integrate the disparate system by utilizing IEC61968. 相似文献
