First, a map between the cones and tangent surface on C-Bézier curve und two-dimensional plane is found respectively and then a ruled surface between two Bezier curves is constructed and a sufficient condition on its developablity is given.

zier曲线上锥面、切线曲面的展开方法。然后，构造两条空间B？zier曲线上的直纹面，给出了它成为可展曲面的一个充分条件，并通过保角保长原则，将其贴合到平面上。

Symmetry group is semisimple, the system has a fine cascade decomposition that is a qasi-parallel decomposition, which is corresponding to the decomposition of linear systems under the semisimple symmetry algebra.

由于对称代数对线性系统的结构有重要作用，特别是当该代数半单时，系统可分解为多个独立的子系统，因此如何就给定的线性控制系统构造出其对称代数具有重要意义。

Of all the above, the constructor is used mainly to generate and set ports and parameters; Ports acting as the channel for data transmission among actors are defined as input ports, output ports or input/output ports. They are also set as single port or multiple ports; parameters are used to allocate actors. In the document, it may be set as an default value or as vacancy to define the data type of parameters, while the specific function to be implemented by the actor shall be defined by public method. Within the actor, the implementing sequence and functions of the method is generally seen as follows

其中构造函数主要用于创建和设置端口和参数；端口作为角色间数据传输通道，它被定义为输入端口，输出端口或输入/输出端口，并被设置为单端口或多端口；参数用于配置角色，它在文件中可设有默认值或为空，并定义参数的数据类型；而角色执行的具体功能由公有方法定义，角色内这此方法的执行顺序及功能一般如下

In order to ensure the strict feasibility of the optimal solution, in the lower-level of program, the constraints are imposed on the confidence upper bounds of the structural responses by constructing the "bounding ellipsoid", which can be obtained efficiently by solving some convex LSDP problems.

对于下层优化问题，本论文构造定界椭球，通过求解凸的LSDP模型来得到结构最不利响应的一个严格上界，确保了鲁棒结构优化设计的可置信性。

This paper adopts the method of the combination of theoretics and experiment. It guides the experiment by academic analysis. On the contrary, results of the experiment can verify the correctness of the theoretics. It has provided the foundation for the conformation design of the connection area between arch rib in the side and rigid tie bar of the Xinguang bridge and its conclusions can also provide references for the design of other same type bridges.

本文采取理论分析与试验研究相结合的方法，通过理论分析指导试验研究，反过来用试验研究验证理论分析，为新光大桥边跨钢拱肋与刚性系杆连接区域构造设计的完善提供了依据，其结论也可供其它同类型桥梁结构的设计研究提供借鉴。

The main research contents and results are as follows:(1) Based on much geological data and the Surpac software,the three-dimensional visual model of Jinchuan Deposit had been built.It would distinctly and visually demonstrate the three-dimensional relationship among the Jinchuan ore-bearing ultrabasic rockbodies,the Jinchuan main orebodies and the Jinchuan main structure.

论文的主要研究内容及成果如下：(1)在收集和综合分析大量地质资料的基础上，利用Surpac软件，建立了矿床三维可视化模型，明晰、直观地表现了矿床含矿超基性岩体、主矿体、矿区主要构造之间的三维空间关系。

Futhermore,we obtain the correspond-ing reflecting K matrices which include those used by Arnaudon and Maassarani toconstruct a commutable family of transfer matrices.

得到的反射矩阵包括了Arnaudon和Maassarani用来构造可对易的transfer矩阵的反射矩阵。

At the end of Phase II we will have design scenarios backed with experimental data to show the feasibly of the space elevator, allow for defendable estimates of when the space elevator can be constructed and define the efforts that are required to complete the design and construction of a space elevator.

在状态 2 底我们将会有设计情节以实验的数据支持了表示那能实行地空间提肌，考虑到可防护估计当空间提肌能被构造而且定义努力的时候那是完成空间提肌的设计和工程所必要者。

C With eversible prothoracic gland (except Melalophaanachoreta Fabr.).

3天社蛾幼虫的上唇和上颚的构造可供分类学上的应用。
