First I definite residual claim right, the residual claims and residual right of control, the state holding companies and corporation father structure; for getting some things of use for reference to the state holding companies I particularly contrast southeast Asian fathering structure, Britain -American father structure and Japanese-German fathering structure. Then the article reviews the development course of the state holding companies and open out profundity causes which are very concentrative property rights, syncopate government and firm decision- making, excessive agency and cost on the high side and so on.

全文从"剩余索取权和控制权"、"国有控股公司"、"法人治理结构"等概念入手，通过详细对比东南亚、英美和日德三种模式，以吸取对我国国有控股公司改革有借鉴意义的东西；接着回顾了我国国有控股公司产生、发展历程，揭示出我国国有控股公司治理结构不完善的深层次原因是产权过分集中、决策政企合一，代理层次过多、代理成本偏高，内部人为控制严重等等。

This paper, which focused on the structure optimization theory and method, has finished such studies as follows: The three dimension model has been built, which provide the necessary conditions for the building of the dynamics equivalent model. By the launch dynamics simulation, the loads of the key joints when the rocket is launched has been got, which provide the necessary data for the finite element analysis and the structure optimization. The finite element model of the excess weight parts of the rocket has been built, buy the finite element intension analysis of the model in two conditions, the displacement and the stress of the key points have been got, which make us know the distributing of the stress and the transmogrification of the part. To satisfy the intension and the precision design request and to decrease the weight of the part as many as possible, the part has been topology optimized by the structure optimization theory and method. After that, the new model has been analysis in structure and launch dynamics. The contrast of the character change of the old part and the new part and the influence on the rocket system have been studied.

Coordinate sequence method is made up of the instruct information of polygon boundary x, y coordinate. It is the easiest polygon vector encoding method. The file structure of this method is easy, but because of the polygon boundary has stored two times, it will produce data redundancy, moreover, short of neighbor threshold information; Tree index encoding method make all the boundary points digitizing, store the coordinate sequence, connect the point index to boundary line, and then connect the line index to other polygons, so as to the tree index structure has came into being. It eliminates neighbor polygons boundary data redundancy problems; Topology structure encoding method is a method which by setting up a complete topology relationship structure, resolve the neighbor threshold and island information process problem. However, it makes arithmetic more complicated and makes database bigger.
