The first is that a symplectic structure or a Poisson structure exists on the even dimensional phase space or on the odd dimensional phase space of the corresponding equations. The second is that there is another symplectic structure or another Poisson structure on the generalized phase space which consists of original phase space and independent variable space.

第一、系统在相空间上存在一个一般辛结构或者Poisson结构；第二、系统整体在包括了自变量的增广空间上存在一个一般辛结构或者Poisson结构；第三、第一个结构若是依赖于自变量，那么系统必然受到外力作用（偏微分方程也有特殊的情形，我们在第五章会加以说明），而第二个结构的则给出了第一个结构和外力之间确切的对称关系。

In this paper we build a university scientific research management information system based on Client/Server and three-layer structure of ASP technology, and introduced the design aims, tasks and principle of the system with systematic investigation and analyzsis of demand., With the principle of integrality, practicability, opening, precursive and generality, data stream and data structure are analyzed detailedly, and logistic model which fits university scientific research management was established based on advanced structure system analysis method. In addition, it puts forward a series of the whole scheme of scientific research management system which bases on internet adapts large database development.the design of this system adapts new internet/intranet techonlogy and it can make us gather and share the whole provincial university scientific research information.lt studies and establishes oology structure and using platform of our provincial university scientific research management system, In addition,it also designs and formulates the system at the experimental unit(the scientific research department of NEAU).The scientific research management information system of NEAU is one part of the network information management system.

Since 1999, the Russian economy has witnessed a rapid growth. However, the Russian government did not take advantage of this favorable opportunity to carry out industrial restructuring, but rather adopting a "passive adaptation" policy, which results in Russia's dual industrial structure today. On the one hand, Russia's total industrial structure has undergone positive changes, not only there has been preprimary adjustment in the relationship between the three industries, but there is a high-level trend in the industrial structure; on the other hand, the internal structure of Russian industry seems to become more unreasonable, even somewhat backwards.

在1999年以来俄罗斯经济的迅速攀升中，俄政府没有利用这一有利时机进行产业结构调整，而是采取"消极适应"的政策，于是出现了今天俄罗斯产业结构的双元现象：一方面，俄罗斯总的产业结构发生了积极的变化，不仅三次产业的关系得到了初步的调整，而且产业结构出现了走向高级化的趋势；另一方面，俄罗斯各产业内部的结构愈发不合理，甚至呈现倒退的态势。
