首先在被测运动物体粘贴标志点，布置传声器阵列和两台摄像机，对摄像机进行标定，得到投影矩阵；传声器阵列获取被测运动物体中声源的声压信号，摄像机获取被测运动物体的动态视频，将动态视频拆解成图像；在视频图像中识别出被测运动物体上的标志点，对匹配后的标志点进行三维重构，获取被测运动物体的空间位置；对声压信号进行波束成型处理，得到被测运动物体的声场特征函数分布图，将其视频图像进行逐帧空间坐标叠加，并还原成动态视频图像。

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.

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.
