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。

Result we get the Hamiltonian expressed by Hubbard operators of the spin-ladder model.

Scholarships in the unusual category range from grants for accordion players, asthma patients, amateur radio operators, bird watchers, bicyclists, blind students, boy scouts and girl scouts, bowlers, cartoon experts, children of veterans, choral singers, cheerleaders, debaters, entrepreneurs, farmers, French speakers, Gospel musicians, grandchildren of alumni, Huguenot descendants, never married students, overweight students, etc. This list just gives a glimpse at some of the categories, while in actual, there are much more of such unusual scholarship requirements, new ones are also being added on a regular basis.

不等的奖学金补助类别寻常手风琴选手，哮喘患者，业余无线电操作员，旁观鸟、自行车、盲生、童子军和女童子军、保龄球、动画专家、儿童老兵，合唱歌手，啦啦队的议事、企业家、农民法国议长、福音音乐、孙子女校友，huguenot后裔，从未结婚的学生，学生超重、等等这份名单只是给予一瞥一些类别，而在实际，还有更不寻常的奖学金等规定，新的矛盾也正在形成定期补充。

Furthermore, in view of the stiff competition in the travel and tourism market, difficulty in preserving outdoor sculptures, the hydra-headed government laws and regulations, and the park area service and planning problems, operators indeed face a tough challenge ahead of them.

此外，面对旅游市场竞争激烈、户外雕塑艺术品保存不易、政府法规又多头马车以及园区内服务与规划等问题也使得业者面临不少挑战。

Auto-configuration and management of the system node on the base of communication has been implemented in the subject. On one hand, self-management of the system has been figured out. Not only variety in I/O ports but in bus nodes or modules, as long as keeping the data in the system configuration database in accordance with the physical conjunction, the software and hardware of the system need not to be calibrated by the operators.

本课题在实现通讯的基础上，实现了对系统节点的自动配置和管理，一方面实现了系统的自我管理，无论是IO点的变化还是总线节点、模块的变化，只要保持系统配置数据库中的数据与物理连接相一致，系统的软、硬件无需人为改动。

In chapter 3,we analyze the global attractor of static reaction-diffusion neural networks with time-varying delays using the semigroup theory of operators, the inequality skills and the imbedding method in Soblev space. A very useful and convenient criterion on the existence of the location of this global attractor is given. Furthermore, we can estimate the location of this global attractor in the space.

在第三章中，我们用算子的半群理论，不等式技巧和Soblev空间的嵌入方法分析了变时滞静态反应扩散神经网络的全局吸引子，给出了一个简洁实用的判定全局吸引子存在的准则，进而，估计了全局吸引子在空间中的位置。

So even higher request is put forward to security and economy of electric power production, moreover operators are requested imminently to have better management of technology and operation and ability to response the emergency.

这样对电力生产的安全性和经济性提出了更高的要求，并迫切要求机组运行人员具有较高的技术、操作水平和应变能力。

Generally, C extension modules are used to implement flat function libraries, and they wind up appearing as importable modules to Python code. C extension types are used to code objects that generate multiple instances and may optionally support expression operators much like classes.

通常，C扩展模块用来实现单一的函数库，它们对Python代码像是可导入模块。C扩展类型用来编写对象，对象可生成多个实例，可以支持表达式操作符，就像类。
