The decomposite-optimized system is discussed by combining the principle of geometric programming and a new view—the comprehensive optimization of hierarchal geometric control in systems is proposed.

在某一个时刻，系统受到未知的扰动，于是使系统从给定的稳定状态转变到另外的已知状态。

This paper discusses the kernel of the system -- geometric model and includes the following:(1) The topological elements and the relation between them in geometric modeling system are explained and expressed by the theory of simplicial complex and CW-complex. In addition, the identification operators and homology theory in algebraic topology are used in our model. A hierarchical structure is built on the base of complex.

本文主要讨论这个系统的核心问题——几何建模问题，包括以下几个方面内容：(1)用单纯复形和CW复形的理论来解释和表达造型系统中的拓扑元素和拓扑元素之间的相关关系，并将代数拓扑中的粘合操作和同调论应用到模型中，建立以复形为基础的层次结构。

In Plato's "Symposium", Aristophanes argues that the origins of love lie in the search for symmetry, while Pythagoras and Theaetetus—who discovered the icosahedron, the geometric shape with 20 triangular faces—explored the symmetries of geometric figures.

在柏拉图的《会饮篇》中，阿里斯托芬提出爱的缘起就在于对对称的寻觅，而毕达哥拉斯和发现由二十个三角形面组成的二十面体的泰阿泰德则探究几何形体的对称。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
