Combined with CAD software development of grids,the design method of bolt-sphere joint is put forward based on geometry restriction and intensity restriction. The geomitry dimension of each component is determined firstly based on bolt diameter and contexture, then, maximal pull and stress of diversitied bolt are given after intensity restriction of all components is taken into acount.

在网架结构中，节点起着连接汇交杆件、传递屋面荷载和吊车荷载的作用，而网架结构属空间杆系，汇交于一个节点上的杆件至少有 6根，多的可达 1 3根，各杆件间的夹角大小不同，且节点各构件间的几何关系或强度关系相互制约，使得节点设计十分繁杂。

Major findings include:(1) Students tended to follow the writing convention of argumentative essays by simply dividing their compositions into three paragraphs, and the poor connection between the three parts made the compositions incoherent in overall organization;(2) Great number of inappropriately used cohesive devices seriously impeded the cohesion within paragraphs in students" writings;(3) Deficiently assembled thematic progression patterns were identified, which also proved that students" writings were incoherent in meaning.

主要分析结果包括：1。多数学生作文写作段落的形式上与议论文与作规范统一，但文章各部分内在衔接不好，导致作文从整体结构上不连贯。2。学生作文中出现的大量衔接手段错误使得作文令人费解。 3。学生使用了几种议论文中常用的主谓推进模式，但这些模式之间结合不紧密也证明了学生作文在意义上的不连贯。

Based on the ICMmethod,the discrete topological optimization problem about spot-weld's existence or not is transformed into the continuous optimization problem on[0,1].The optimization model is founded with maximizing the structural stiffness as objective and structural strength as constraints.The problem of multi-objectives and multi-constraints is transformed into the problem of single-objective and single-constraint with the K-S function.The displacement and stress are transformed into the explicit function of design variables with the Response Surface Methodology.The optimization model is solved with Sequential Quadratic Program.

基于ICM（Independent Continuous Mapping，即独立、连续、映射）方法，将焊点有无的离散拓扑优化问题转化为[0，1]区间上的连续优化问题；建立了以结构刚度最大为目标、结构强度为约束的连续拓扑优化模型；采用K-S函数将多目标和多约束问题转化为单目标和单约束问题；运用响应面方法将位移和应力转化为设计变量的显式函数，采用序列二次规划方法求解优化模型。

Then we re-sampling all signals defined on the surface of the original triangle mesh at the vertices of the spherical subdivision mesh and get a set of discrete geometry signals with subdivision topology which can be compressed by using spherical wavelet.

于是，在参数域内位于细分网格顶点处对定义在参数网格表面上的各种几何信号进行重采样，可得到新的具有细分结构的几何信号近似表示原始几何信号，以此满足球面细分小波对处理对象的细分结构要求，从而使得用球面细分小波对几何信号进行压缩得以实现。

In addition, this paper gives the definition of the dual system. This definition can be used in the condition of independence and dependence.

另外，在结构函数定义的基础上，本文又给出了对偶结构函数的定义，这个定义对部件之间独立和相依的情况都是成立的。
