The main research contents are stated asfollow: 1. Simplified analysis method of space grids structuresDouble-layer space grids have been assumed as sandwich plate, and are analyzed bythe nontraditional theory of plate with consideration of shear deformation and threegeneralized displacements. Using the theory of energy variation, simplified methodsfor bending, stability and vibration analysis of double-layer space grids have been putforward based upon the idea of split rigidity. The formulas for calculating internalforces, displacements, critical load and natural frequency have been given out. Set thestable cables and bearing cables in hyperbolic paraboloid cable nets are all replaced bytruss-cable to form truss-cable nets structures. Natural vibration analysis method fortruss-cable nets structures has been put forward using the energy variation method andRayleigh method.

This thesis adopts the economic analytical method of the law to carry on the discussion to the range of the right hypothec mainly, the rational distribution of resources and effective use of resources are the motive force of the social development, legal right itself one resource, certain right is it go on way that utilize to certain resource to represent, the right hypothec is a way to utilize resource too, the bigger the range of the mortgage token of the right one is, the more ways to utilize resource are.

本文主要采用法律经济分析方法对权利抵押权的范围进行探讨，资源的优化配置和资源的有效利用是社会发展的动力，法律权利本身就是一种资源，一定的权利就代表了对一定资源进行利用的途径，权利抵押权也是利用资源的途径，权利抵押权标的的范围越大，利用资源的途径就越多。

The jet pump to water vapor as the main driving force media.

在喷射泵中主要以水蒸汽作为动力介质。

S. dollars and the decline of the Cold War provided the economic and political environment for European countries to integrate. For encouraging the economic incentives, major European countries' ruling parties ended the policies of Keynesian School and constructed a relative convergence for a European-wide laissez-faire economic policy. However, the most important impetus for the building of the European Union is the less strengthened role of the European region in the global competitiveness. For yielding part of their sovereignties, EU countries can enlarge their capacity, and survive much stronger in a global World.

当然，促成欧洲联盟形成原因甚多，不过欧洲在全球化竞争中居明显劣势地位仍是欧洲整合再出发的最主要堆动力，本文指出各国政策汇合因素只能算是新区域整合的必要条件，仍非充分条件，最大因素仍应是欧洲各国为因应全球化桃战形成的新区域整合，也即籍助於让渡部分主权，欧盟各国因而更能扩大本身的职能，於此，两岸似亦应从中获得相当放示才是。

Based upon the introduction above, the works in this paper focused on the simplifiedanalysis method of space grids structures and the research on wind-resistantperformance of single-layer latticed dome.
