MEFP periodically selects cluster heads according to the node residual energy,incurs low message overhead,achieves fairly uniform cluster head distribution across the network,and the regular node joins the cluster which has the minimal energy-forward among cluster heads,this tactic can avoid forwarding sensing information circuitously.

提出了一种转发能量最小的无线传感拓扑算法MEFP（Minimal Energy-Forward Protocol），算法减少成簇的通信开销，在网络中簇半径区域内仅产生一个簇头，保证了分簇的均匀；在普通节点加入簇的过程中，选择转发功耗最小的簇头加入，避免迂回发送数据，降低了能量消耗。

From the point of the cluster of the small and medium-sized enterprises of Shaodong, this thesis studied the forming and development of the cluster, analyzed the existing problem and reasons of the cluster, compared and contrasted the "mode of shaodong " with " mode of Wenzhou ", and also analyzed the similarities and differences between these two modes, therefore summarized a few pieces of enlightenment for the development of the cluster .

本文从邵东的中小企业群集出发，研究了邵东中小企业集群的形成与发展情况，剖析了邵东中小企业集群发展存在的问题及原因，并与"温州模式"作了对比，分析了这两种"模式"的相似之处及不同之点，由此为邵东中小企业集群发展总结出了几点启示。

The firms located in industrial cluster are important ties that linked the local industrial cluster and the global production network. They are as well as the micro-dynamics for the clusters' upgrading and evolution in the context of economic globalization. The existing researches on industrial cluster almost focus on the cluster's competitive advantages as a whole unit, which has supposed the firms in clusters are homogeneous and opportunity equipotent that can get extra advantages compared to the un-clustered firms.

集群企业正成为联系地方产业集群与全球生产网络的重要纽带，是经济全球化背景下产业集群升级和演进的微观动力；从已有的集群理论研究成果来看，目前的研究主要集中于集群整体层面，研究的焦点是对集群整体的竞争优势进行探讨，集群企业被假定为是具有同质性和机会均等性的，相对于非集群企业可以获得一种"非对称"的特殊竞争优势。

The Gayal separated the yaks far away and formed one cluster and 9 yak breeds grouped together. Analysis of population structure for 9 yak breeds shows that there inferred three clusters, one cluster includes yaks in Tibet Autonomous Region and Qinghai Province, the other cluster combines Zhongdian, Maiwa and Tianzhu White, and Jiulong and Xinjiang come into the third cluster.

进一步分析9个牦牛和大额牛的群体结构发现：10个种群可分为4个亚群体，一类是青藏高原的牦牛，一类包括中甸牦牛、麦洼牦牛和天祝白牦牛，第三类包括九龙牦牛和新疆牦牛；帕里牦牛主要分布在第一亚群体中，占90%，九龙牦牛主要分布在第二亚群体中，占87.1%，中甸牦牛主要分布在第三亚群体中，占83%，其他品种分布在2至3个亚群体中；大额牛独立分布在第四群体中，占99.3%。

In homogeny cluster head hierarchical topology, the article first discusses the selection of cluster head. With a given formula on weights, a suitable cluster head node is selected. And according to the relationship of location with cluster head node, the gateway nodes and the distributed gateway nodes are selected.

簇头同构的分簇算法中，首先讨论了簇头的选择，给出了一个权值设定公式，按照权值大小，选择出合适的簇头节点，然后根据和簇头节点的位置关系，确定网关节点和分布式网关节点。

Cluster sampling: When the basic sampling unit in the population is to be found in groups or cluster s the sampling is sometimes carried out by selecting a sample of cluster s and observing all the members of each selected cluster .

整群抽样：一种抽样方法。当母体中的基本抽样单位是按群、组分类时，有时抽样方式是选择一类样本群组，然后对被选择的群组中的每一个样本单位的全体成员进行观察。

Firstly,the sampling design has great impact on the accuracy of remote sensing classification.There exists great randomicity on the result of points and cluster sample verification on the different Sampling design.On the same sampling design,the stability of point sample verification is higher than that of Cluster sample verification.Secondly,the average accuracy of different sampling designs of multi-point and multi-cluster sample verification can reflect the accuracy characteristic.During the course of point sample verification,stratified sampling's error is lower than others'.During the course of cluster sample verification,systematic sampling and stratified sampling's accuracy are prior to simple random sampling's.

研究结果表明：（1）抽样方式对遥感分类精度评价结果的影响是客观存在的，不同抽样方式下的点样本和群样本检验结果都存在一定的随机性，但同一种抽样方式下，点样本检验精度评估结果的波动幅度小于群样本检验，稳定性比群样本检验要好；（2）不同抽样方式下的多次点样本和群样本检验的平均精度检验结果基本上都能够反映分类图像的精度特征，其中，点样本检验中，分层随机抽样点样本检验效果较好；群样本检验中，系统抽样群样本检验和分层随机抽样群样本检验的效果优于简单随机抽样群样本检验。

This paper briefs the basic principles of " transitive closure " cluster analysis based on fuzzy equivalent relation and fuzzy ISODATA cluster analysis based on soft division technique, and advances a classification and recognition method by combining K-L transformation and the two fuzzy cluster methods above, which makes full use of the advantages of both cluster methods.
