This paper's work is trying to present a more efficient method to locate the agent in distributed networks on the basis of pioneers' researches, and assess the performance of this method.This paper begins its discussion with agent technology's background and basic conceptions, characteristics, and presents the researched problem, that is, researching new agent locating method; then introduces several traditional locating methods: brute force searching, database method and path proxies, and analyses their features and locating efficiency. For describing the agent locating better, this paper formalizes the agent, presents a proper definition, and abstracts agent's migration process, proposes a metaprocess concept and decompounds migration process with it.

本文首先介绍了代理技术的产生背景以及基本概念、性质，提出了需要解决的问题，即对新的代理定位的方法的研究；然后总结介绍了前人文献中的一些代理定位方法：穷举搜索法、位置数据库法和迁移指针法，并分析了这些算法的优缺点和代理定位效率；为了更准确的描述代理定位，本文对代理进行了形式化，确定了一种适合的代理定义，并对它的性质给予形式说明；在此基础上抽象出代理迁移的本质，根据它对资源的控制对迁移类型进行分类；提出元过程概念，并分解表示定位过程，并介绍了过程时间连续性。

RESULTS:Our results indicate that the chemokine CCL5 can induce migration in humanbreast carcinoma cell line MCF-7 in vitro and suggest a potential role for Ezrin in theprocesses of breast cancer cell migration,invasion and possibly metastasis responsed toCCL5.We demonstrate that Ezrin siRNA specifically inhibits Ezrin expression of MCF-7cells and deregulates several functions such as cell motility and cell invasion,indicatingthat Ezrin plays a key role in the development of human breast cancer cells.It\'s suggestedthat Ezrin may act as a new anti-invasion therapeutic target for human breast cancer.

趋化因子CCL5促进人乳腺癌细胞MCF-7的趋化与侵袭，Ezrin蛋白的激活在此过程中起着重要的作用；成功构建Ezrin特异性siRNA表达载体，可用于探讨乳腺癌的侵袭转移机制，并为有效地抑制肿瘤的转移提供新的生物治疗靶点。

Compared with the other migration methods, reverse-time migration is based on the accurate wave equation but not its approximate formula and extrapolates wave field along time axes instead of depth axes.

与其他偏移方法相比，逆时偏移基于精确的波动方程而不是对其近似，用时间外推来代替深度外推。

While the interferometric migration method migrates cross-correlated seismic data, the data-referenced-only migration method has no such apparent procedure. It extrapolates different parts of the recorded seismic wavefields and these extrapolated wavefields are referred to each other during imaging.

地震相干偏移是用地震数据的互相关处理后的数据进行偏移，而数据自参照偏移则不必在偏移前对数据进行互相关处理，而是通过记录数据中的两个不同部分波场的延拓来互相参照进行偏移。

After they reached Yunnan, Hans migration had become Yunnan people from foreigner through garrisoning, opening up wasteland, growing food grain, settling and combining with land. Their distribution showed that they concentrated on main cities, important military fort, and inner basin plan and along traffic lines and pushed forward to the mountain areas where minority lived. Consequently, the status where an area inhabited by Han and other nationalities established the nationalities distributing pattern of Yunnan in latter-day. Th productivity labor of Hans migration pushed forward the social productivity of Yunnan.

他们的定居分布具有中心城镇屯聚、内地坝区密集屯田、交通干线的驿堡屯戍并向次要道路和边远民族山区层层推进的态势，奠定了云南近代汉族与少数民族杂居而形成的各民族大杂居、小聚居的分布格局；他们的生产活动推动了明代云南社会生产力的巨大发展；他们土著化过程中的阶级分化，不仅促进了云南地主经济的广泛发展，推动云南的社会变革，更重要的是汉族移民壮大云南知识分子力量和人口基础，促进知识分子士绅阶层在明代云南社会中广泛兴起，标志着云南人口素质有了很大提高，对云南社会产生了深远的影响。

The interlayer oxidized zone and the concentration of uranium has the typical characters of low temperature geochemical processes. Interlayer oxidized zone can be defined from the bedrock to horizon C under hypergene weathering by such parameters as chemical metamorphosing、index of chemical weathering and index of mineral chemical differentiation.(2)Major elements can be divided into sensitive group、 active、 weak active and inert groups according to chemical metamorphosing parameter and fractional migration potential. For major elements of multivalent in the active group( Fe_2O_3、 FeO) and U, the migration and concentration trend in interlayer oxidized zone is apparent.
