In accQrdance with the concerned isomerism and distributivity of the database system in the long-distance education, and variety of database inter-connectivity technology, we law lessons from the successful application in TCP/IP communication protocol, and adapt to use the Layer thought to realize the share of distributive isomeric database information.

针对目前远程教育中所涉及的数据库系统的分布性和异构性，数据库互连技术的多样性，本文欲借鉴网络通信协议的成功之处，采用分层结构的思想去实现分布式异构数据库信息的共享。

Is the theory as a guide, the selection of a heterogeneous catalytic function of inorganic salt, the efficient preparation of compound catalyst, can make the original conversion rate of increase heterogeneous 4 to 5 percentage points, reducing the pollution of the environment and can significantly reduce Fumarate production costs and have a good economic and environmental benefits.

是以相关理论为指导，遴选有异构催化功能的无机盐，制备复合型的高效催化剂，可以使原有的异构转化率提高4～5个百分点，减少对环境的污染，且能显著降低富马酸的生产成本，有很好的经济效益和环保效益。

ABSTRACT This thesis is to implement seamless integration and information sharing of heterogeneous databases distributed geographically on ...

对地理上分布的多个异构数据库，在尽可能少地影响其本地自治性的基础上，对其进行无缝的集成，实现异构数据库的信息共享是本文的研究目标。

And according to area of Microsoft big China chief skill watchs Introduction Li Zhixiao, be in China, microsoft pays close attention to 3 kinds of each other to operate setting, include same the each other operation of the each other operation of identical documentation format on platform of compose of the each other operation of a different documentation format on platform, different and the documentation format that different differs on compose platform.

而据微软大中华区首席技术观李志宵介绍，在中国，微软关注三种互操作场景，包括同一个平台上的不同文档格式的互操作、异构平台上相同文档格式的互操作以及异构平台上不同的文档格式的互操作。

We also strongly suggest that the recently reported chaperone acitivity of periplasmic PDI-ase and PPIase assayed by traditional substrate should be reexamined using periplasmic proteins as substrate due to the significant difference between those two classes of proteins, the possible chaperone fuctions of PDIase and PPIase in vivo should be reappraised.

同时，由于本实验结果显示膜间质蛋白与常用的分子伴侣测活底物蛋白在聚集行为上存在极显著的区别，我们建议对最近报导的膜间质蛋白二硫键异构酶和脯氨酸顺反异构酶分子伴侣活性以膜间质蛋白为底物再进行验证，对其在膜间质是否发挥分子伴侣功能重新慎重考虑。

Results indicated that pesticides show different variability in certain extent in relative response between different matrixes. Certain pesticides are matrix-dependent such as chlorothalonil, paraoxon, deltamethrin, methamidophos, acephate etc, among them, chlorothalonil have better relative response in acidic matrixes (as orange, tomato, grape, kiwi fruit) but have serious suppression in scallion, onion, garlic, leek, lotus root etc.

结果表明，各农药相对响应值具有不同程度差异，个别农药显示了较强的基质依赖特点(如百菌清、对氧磷、溴氰菊酯、甲胺磷、乙酰甲胺磷)；其中百菌清在酸性基质橙子、番茄、葡萄、猕猴桃、蘑菇中稳定，其基质对百菌清起到了保护性作用，且能够抑制或减少溴氰异构体2向异构体1的转化；而在大葱、洋葱、蒜、藕、梨等基质中存在显著的降解或抑制作用。

Objective:To establish a method for determination of the concentration of the stereoisomers of soman in mice brain and diaphragm after soman was subcutaneously administrated to mice.

梭曼有一个不对称的碳原子和一个不对称的磷原子，因此有 4个光学异构体，即CP ，CP ，CP ，CP ，这些异构体的毒理学及代谢特性差别很大。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
