In current network applications , c / s modal is the mainstream . but with the quick development of the distribute computing and new network technology , more and more people focus their attention on p2p modal in recent days . the main difference between p2p modal and c / s modal is that the former does n ' t rely on a server , thus control is distribute . some modals of p2p even do n ' t require a server . the p2p modal has excellent redundancy . no single fault point in p2p modal . p2p modal can be a good complementarity of c / s modal . and of course , as a new technology , p2p modal is not maturate . it even has n ' t a standard protocol till now 而随着分布式计算的深化和网络技术的进一步发展，对等式网络模型( p2p )开始受到重视，并成为最近的技术热点之一。 p2p模型与c s模型相比，最大的不同是降低了对服务器的依赖及其分散控制，一些p2p模型甚至不需要服务器。 p2p系统的冗余性很好，没有单一的失败点。
The paper points out that talent personnel , system , capital , and government functions are the important aspects of carrying out the strategic objective of dstdz , frames the strategic development schedules of dstdz , that is introducing well maturated high tech enterprise from nation and abroad , building infrastructure area by area , realizing the accumulation of the first cost and congregation of the industry resource , forming the zone development in good circulation , and accomplishing the building task at the beginning of establishing dstdz on the basis of establishment of high tech industry park and the incubator of science and technology enterprise 本文从人才、机制、资金、政府职能等四个方面指出了贯彻实施德阳高科技园战略目标的重要环节，为德阳科技园的发展制订了战略步骤：引入国内外比较成熟的高新技术企业，逐片开展基础设施建设，在初步形成高新技术工业园区和科技企业孵化器的基础上，实现原始资本的积累和产业资源的聚集，形成科技园区发展的良性循环，完成科技园区初始建设时期的任务。
Up to now , the geosynthetic reinforcement mechanism is still not very clear ; design method is not maturated ; and theoretical research lags behind engineering practice , to some extent , which hinder the application of geosynthetics . therefore , it is necessary to make further researches on geosynthetic reinforcement 目前，土工合成材料的加筋机理不十分清楚，计算方法不成熟，理论研究明显落后于工程实践，一定程度上限制了土工合成材料的工程应用，因此迫切需要对土工合成材料加筋土进行深入的研究。
