Main points of the thesis are as follows:(1) The main function models and information relations between these models in the CAPP system in the integrated CAD/CAM project are explained, a new process plan design method is mentioned based on analyses of process plan design. This method is based on the process plan prototype, and develops the prototype little by little until the perfect process plan is completed, the prospect of this method is discussed;(2) The feature abstracting rules and methods are studied, a feature coding system is developed based on GT, all the defined feature models are described by the mathematical methods;(3) The integrated method of CAD/CAPP based on features is mentioned, this method defines a feature exchanging model, and develops an interface software to exchange design data into technology data base, this technology data base includes the design and technology information of the parts;(4) The process plan reasoning method based on features is created, this method uses Mycin algorithm to solve the reasoning of the feature process plan. A process plan making system is developed. In this system part process plan is made by the semi-intelligent method, this method uses the feature reasoning, feature process chain searching and man-computer talking together;(5) The main structure of the HOPE system is introduced, a shaft drawing and its process plan made by this system are shown, the data process problem in process drawing making is also discussed;(6) A new method of describing process rule is introduced, this method uses IfThen rules and neural nets weight values together to describe process rules, the BP algorithm is adopted in this method;(7) The optimal machining sequence problem of the process steps on the same fixturing is discussed, optimal algorithms SA is applied to solve this problem, the result shows that this method is more efficient than the traditional method;(8) All jobs in the thesis are summarized. In order to carry out the research in the future, some rational proposals are given.

This is true despite the multiple blood supply scandals of the past decade: from the large number of plasma sellers who contracted HIV via inappropriate collection procedures in the mid-1990s; to the many haemophiliacs in and outside Shanghai who find themselves carrying HIV and hepatitis since the new millennium, to people infected with HIV/AIDS via blood transfusions and blood products.

自从20世纪90年代中期出现的中原血祸（大量卖血浆者感染艾滋病病毒）、到进入21世纪以来发现的大量上海和上海以外地区的血友病人发现感染艾滋病病毒和肝炎病毒、到遍布全国的输血感染艾滋病病毒者，我们却震惊地发现，我国政府一直缺乏一个综合处理相关血液及制品供应和安全事务的协调机制。

As a postgraduate majoring in vocal music, I developed a deep passion for the piece of music through the study of the original materials and practical singing on the concert. I feels that is of great value to make further study about it. Therefore, I gathered a lot of materials, study of the German pronunciation, analysis of the videotapes and other comprehensive devices to explore deeply the implication of the divertimento and its ideological thoughts.
