This paper make a general analyze of the SMES Cluster, define the conception of SMES Cluster, the forming of SMES Cluster and the basic types of SMES Cluster, study the important function of the SMES Cluster to the country, the district and the enterprises selves.Second, this paper research comparatively of three different international SMES Cluster cases and three different domestic SMES Cluster cases. Three different international SMES Clusters include the Italianism SMES Cluster, the Croatia SMES Cluster and the SMES Cluster which are formed by the multinational corporations" investment. Three different domestic SMES Clusters include the Zhejiang province SMES Cluster, Shandong province SMES Cluster and the Zhongguancun SMES Cluster.Finally, on the basic of analysis in cases, according to the current situation of Jiangsu and analysis of cluster development condition of SMES, explore the SMES Cluster development mode and pattern in Jiangsu. The main types of SMES Cluster in Jiangsu include Spontaneous growing up type, enterprise"s expanding type, market driving type, urging type of science and technology, and driving type of the foreign capitals.

本文通过对中小企业集群的一般分析，界定中小企业集群的概念、形成、基本类型以及中小企业集群对国家、对区域、对企业本身的重要作用；其次，对国外三种不同类型的中小企业集群(意大利式中小企业集群、克罗地亚造船厂式中小企业集群、跨国公司投资形成的中小企业集群)和国内三个不同地区的中小企业集群(浙江省中小企业集群、山东省中小企业集群、中关村中小企业集群)的案例进行比较分析研究；最后，在案例分析的基础之上，根据江苏的现状以及中小企业集群发展条件的分析，探索江苏集群发展的模式和格局，江苏的中小企业的发展模式主要有自发成长型、企业扩张型、市场带动型、科技驱动型、外资带动型。

This knee brace is designed for polio sufferers and the one having unstable lower limbs as well. In fact, the existing knee braces cannot completely meet the design requirements stated above. Therefore, it is necessary to use the same design concept of safe prosthesis knee joint onto that of the knee brace.

此膝支架主要针对小儿麻痹患者或是下肢呈不稳定状态者所使用，由於目前一般膝支架对於前述设计需求无法完全达成，因此藉由相同设计概念将此机构转移至膝支架上。

With the help of the concepts of Lebesgue measure and Lebesgue integral in real function,the mathematics model of concurrent design of life-oriented progressive die is advanced. Which were the Lebesgue measure and Lebesgue integral of die substructures and a general mathematics model of the relation between progressive die structure and die substructures.

运用实变函数中的Lebesgue测度和Lebesgue积分的概念，结合面向寿命的级进冲模并行设计的特点，建立了面向寿命的级进冲模并行设计数学模型—模具子结构的Lebesgue测度和Lebesgue积分，提出了级进冲模结构与模具子结构关系的一般数学表达式。

Furthermore, in order to overcome the disadvantage of GMC, i.e., it can only apply to the processes with relative order of 1, based on Lie derivative, we propose to let the r th derivative of the process output follow the given reference trajectory, to get the control law expression through solving an optimization problem.

针对GMC方法只适于相对阶r为1的简单过程的缺点，采用Lie导数的概念，令过程输出的r阶导数的轨迹为事先设定的标称轨迹，通过解优化问题得到控制律表达式，把GMC方法推广至相对阶r大于1的复杂多输入多输出过程，从而提出了一种广义一般模型控制方法。
