Low level radwaste disposal problems are complex. Many important issue, such as radionuclide migration in the geosphere, must be carefully evaluated before making decision. This project will explore the use of a hydrogeological decision support system for solving these complex problems. The system will integrate hydrogeological analysis tools, geographic information system, mathematical models, stochastic and statistic methods, graphical interface, and decision system. By using the system, it is expected that many different alternatives can be efficiently analyzed and evaluated, and results can be presented much more effective to decision makers, while compared with the conventional presentation. Basing on the prototype system developed in the last two years, this project will integrate more analysis tools and improve the functions of the system.

The article presents the developing condition of PWM and SVPWM first.Then the theory of SVPWM is discussed in detail.The SVPWM is based on the thought of magnetic chain tracking.It makes the ideal magnetic chain circle of three-phased sysmmetry electric motor supplied by three-phased sysmmetry sine wave voltage for basis,uses the practical magnetic chain vector formed by the different switch modes of three-phased inverter to track the basic magnetic chain circle.During the course of tracking,the inverter changes the switch modes properly to form the PWM waves.Then the modulation wave of SVPWM is analyzed in detail.The modulation wave of SVPWM is implicit,but the analogous modulation wave in A-B-C axis needs to be calculated in order to expose the internal relation of SVPWM and SPWM.That is to show the implicit modulation wave of SVPWM. SVPWM actually is a transformed SPWM ruly sampled by the modulation wave which is injected by the zero prefaces based on space vectors.

On the bases of investigating and grasping the materials about the AHPPEs, AHPPEs' developing situation is analyzed completely in this article on vertical direction of time order and horizontal direction of department, in the meantime, material buying process, capital's using rate, and product selling process are also analyzed completely. Pointing out because the differences of owning right among State-Operated Enterprises, Collectively Operated Enterprises and Privately Operated Enterprises, there are differences in the producing behavior and trade development.A. According to the theory of producer behavior, POEs is on the way from stageⅠto stage Ⅱ,economic interests increasing;COEs is on the end of stageⅡ,economic interests decreasing;SOEs on stage Ⅲ,economic interests is negatively increasing.Model analyzing method shows that scale economic doesn't exist in SOEs and COEs, but POEs is the reverse.B. Different owning right enterprises have great differences in the respect of capital scale,product making and selling processes, at last SOEs and COEs' economic interests is much less than that of POEs. Scale economic doesn't exist in SOEs and COEs, POEs have the potential of developing scale economic, furthermore, the new-coming horizontal in the horizontal structure have the good situation.

在跟踪调查掌握资料的基础上，文章对该区农畜产品加工企业的发展状况从时间序列的纵向和行业结构的横向进行了比较分析，同时又从原材料购买过程、资金的利用效率以及产品的销售过程等各个方面进行了全方位地剖析，指出由于企业存在着国有、集体和民营产权类型的不同，导致生产行为和行业发展存在着差异：A、生产者行为理论分析总结出，民营企业正在处于第Ⅰ阶段向第Ⅱ阶段的过度区，经济效益上升；集体企业处于第Ⅱ阶段的末端，经济效益下降；国有企业处于第Ⅲ阶段，经济效益负增长。B、不同产权企业在资金规模，产品的生产和售卖过程上存在着很大不同，最终导致国有和集体企业经济效益比民营企业要差得多，用模型方法分析得出结论：国有企业和集体企业都不存在规模经济，而民营企业存在规模经济的发展潜力，并且在行业结构中属于民营产权的新兴行业发展状况良好。C、行业间也存在着很大的不同：集体企业的优势行业是制酒、粮食加工和肉食品加工等行业；民营企业的优势在皮件类、服装、粮食加工和制酒等行业；国有企业当中食品加工、肉食品加工和食品冷库类是优势行业。
