The four well-known skeleton hydro-power stations of West-East Electricity Transmission Project, named Xiangjiaba, Xiluodu, Baihetan and Wudongde from the lower reaches of Jinshajiang River to upriver reaches, are all distributed in this area. Based on the analysis of the resource exploitation and industry sustainable development status, current problems and future scenarios, the main conclusions go as follows:(1) There are abundant and varied agricultural resources, widely distributed mineral resources with valuable predominant minerals, potential tourism resources, but some main problems such as lower level of exploration and development, serious waste and pollution, restraints of financing and transportation and eco-environmental frangibility still call for immediate solution;(2) Regional economy develops fast but the overall level is low-farming and animal husbandry industries, In which crop-plantation takes the main part, dominates in the sectional structure of economy, and forestry and specialty industries need to be further developed. The existed restraints such as unbalanced structural and regional economic distribution, acute structural deficiency and low economic efficiency need to be cleared out, of the way to a sustainable future.

西电东送骨干工程的向家坝、溪洛渡、白鹤滩、乌东德四大水电站均分布在这一江段通过对该区域资源开发和产业发展的现状、问题和发展前景进行分析，得到如下主要结论：(1)该区域农业资源丰富多样，矿产资源分布广泛且优势矿种地位突出，旅游资源待开发潜力巨大，但是资源开发却面临着勘探开发程度不够、浪费污染严重、资金交通制约和生态环境脆弱等几大问题；(2)区域产业经济发展迅速但总体水平低，部门结构中以种植业为主的农牧业占主导，林牧业和特色产业有待进一步开发，产业发展面临着部类和区域不均衡、结构矛盾突出以及效益低下等问题的困扰。

The authors performed 3D photographic measurement on the technical moves of ZHANG Wen-xiu as an excellent female hammer thrower in China to get relatively comprehensive body movement data by using two JVC3000 high-speed cameras, screened and analyzed the data by using SPSS software, and revealed the following findings: in terms of such technical parameters as spinning time, spinning track and spinning speed, there were some problems with this player, which restricted the enhancement of her performance, such as the double leg supporting time was shorter than the single leg supporting time; the angle of inclination of the track of various swirls (espe-cially the first swirl) was somewhat too big; the accelerating process was too short; too much attention was paid to acceleration at the single leg supporting stage; the spinning at the double leg supporting stage was too fast; the sus-tainable accelerating power was not high.

Based on the comparison of proposed basic topologies, Hypercube, as a popular used topology in networks, has a lot of advantages such as simple routing algorithm, small diameter and average number of internode distance, high fault-tolerance and so on. On the other hand, the network nodal degree which is logarithmically proportional to the number of network nodes limits the Hypercube network population most. So a class of hierarchical topologies are proposed to remedy this weakness of Hypercube and keep most of the advantages of Hypercube, such as CCC , HHC and deCube and so on.

基于对所提出的基本互连网络的性能比较，超立方体网络作为一个得到普遍研究的网络拓扑结构具有很多的优点，比如网络的非常简单的寻路算法，很小的直径和网络平均节点距离，高容错能力等等，但非常遗憾的是超立方体的缺点是超立方体的节点度随着网络规模的增加而成对数关系增加，从而限制了此网络的应用规模，大大地掩盖了它的诸多优点，所以人们提出了一类分层网络结构来弥补超立方体的不足同时最大限度地利用其优点，包括CCC，HHC以及deCube等。
