On the basis of those theories, take the economical development as the goal, the author treats that how the international trade promotes region economy development, including the domain of dependence economic structure constituent reciprocity, grasps function about the international trade to the region economy development mechanism, formulates the most suitable region foreign trade developmental strategy, Thus assure open rhythm of our country region internal economy development, from our country national condition, using the foreign trade to promote the local economy development, cultivate area trade market, promote economies of scale formation, enhance the productivity , meanwhile strengthen this local international competition. Those are important significance of theory and the practice.

在此基础上，笔者以国际贸易理论为导向，以经济发展为目标，探讨国际贸易对区域经济发展的内在促进作用，包括有关区域经济结构组成部分的相互关系，把握好国际贸易对区域经济发展的作用机制，制定最适当的区域对外贸易发展战略，从而正确把握我国区域内部经济开发开放节奏，从我国国情出发，利用外贸促进地区经济发展、培育区际贸易市场、促进规模经济的形成、生产率的提高来增强本地区的国际竞争力等具有重要的理论和现实意义。

Based on analyzing uncertainties when determining indicators system of ecosystem health assessment, an indicators system and a model for the evaluation of urban river ecosystem health was proposed. The model could offer the feasible and reliable base of decision-making for the river environment management.(4) An integrated method for land suitability evaluation based on geographic information systems under uncertainty was proposed.

运用模糊层次分析法，建立基于不确定性的模糊层次综合评价模型，并将理论应用于长沙市河流生态系统，查明城市河流的健康状态，研究结果可丰富河流生态系统健康研究理论体系，弥补当前生态系统健康与修复研究中城市河流方面的缺乏，对退化城市河流生态系统的保护和恢复起到很好的指导作用。

The research work starts from theory of corporate regulation, where it demonstrates that the mechanisms of property right and corporate governance are the core of corporate regulation, to testify that is basement for the development of corporate. In order to have a good corporate, it is very necessary to understand corporate property right and its governance mechanism clearly. Based on theory of corporate property right, it is described of the fundamental requirements of different type of property right on property regulation, effect and function.

在本研究工作中，本人从企业制度理论出发，论证了产权制度和治理制度是企业制度的核心，是企业发展的基础，从而指出要办好企业，必须首先理解什么是产权制度及基于产权制度的企业治理机制；再从产权制度理论入手，阐述了各种产权形态对产权制度的基本要求，产权的作用及功能，对比分析了各种企业形式下产权制度的特点。

Based on point explosion theory , the approximate analytical formulas of momentum coupling coefficient and impulse of cone and parabolic crafts are deduced. The results show that the total axial impact momentum for parabolic craft is larger than that of cone craft and it increases with the increase of half open angle.

以LSD/LSC波理论为基础建立了一个近似的理论解析模型，推导出圆锥形和抛物形飞行器获得的冲量及冲量耦合系数的近似解析表达式，公式表明冲量耦合系数随着半张角的增加而增加，同时抛物形飞行器要比圆锥形飞行器的动量汇聚效果好。

The theory is one of the latest results in the harmonic analysis development.

本文在对化工过程知识认识和理解的基础上，深入研究软测量技术的应用，将数学理论中调和分析技术发展的最新成果小波理论应用到软测量技术的神经网络构建中，取得了较好的效果。

Presently, this new model drive has not been researched. Therefore, the basically theoretical research on the face harmonic motion drive of separate tooth and application is not only developed new type of active teeth drive but also has a definite theoretical significance and economic value.

目前，这种新型的传动方式国内外还没有进行研究，因此，关于散齿端面谐波齿轮传动的基础性理论研究和开发应用，不仅增加了活齿传动的类型，具有一定的理论意义，而且具有很好的应用前景和经济价值。

The main results of this research are as follows:(1) A parallel algorithm for solving dense matrix linear equations on distributed-memory multi-computer is presented. Convergent velocity of this algorithm is better than parallel Jacobi method"s, and parallelism is better than Gauss-Seidel method"s. According to theoretical analysis, convergent conditions are given. Moreover numerical experiments indicate that results agree with theory.

主要完成了如下研究工作：(1)提出了一种求解系数矩阵为稠密矩阵的线性方程组的适合于MIMD分布式存储的并行迭代算法，该算法设计上兼取了Jacobi算法并行性好的优点和Gauss-Seidel算法收敛速度快的长处，并且在理论上给出了该算法成立的收敛性条件，并通过数值计算验证了此算法结果与理论相符合。

The simulation results by applying zero-equation model are compared with those by adopting Prandtl mixing length theory and K-ε two equation model.

研究表明，总体来说Prandtl的混合长度理论能够获得比Chen的零方程模型更好的结果；从这两种零方程模型的构造分析，Prandtl混合长度理论较为合理，但Chen的零方程模型更容易收敛。

After studying the theory of combined signal processing with acoustic pressure and particle velocity, a method of direction estimation underwater, which is based on intensity measurement using an acoustic vector sensor, is presented. In the low frequency field with kinds of line-spectra, azimuth angle estimation is achieved based on the probability density statistics and bar graph approach. It can preferably resolve the problem of left/right bearing resolution and estimate the direction of space.

为了对水下目标进行定位，基于声压与振速联合信号处理的理论，研究了复声强法对水下目标信号的定向技术，并使用概率统计和直方图的理论对目标的方位角和俯仰角值进行了估计，在线谱分量存在的低频段对估计角度进行了概率统计，较好地解决了左右舷的分辨问题，实现目标的全空间无模糊定向。

The distinction may not be the most consequential aspect of the Dushu affair. The suspicion that neo-liberal unhappiness with Dushu's "new left" orientation had something to do with the dismissal is plausible, even though there may have been no direct neo-liberal machination.

汪和黄有很好的处理这些问题的能力，一位是对中国学术遗产和现代理论问题非常熟悉的文化分析者，另一位是在社会理论和现代化问题方面受过良好训练的社会学家，这里的现代化不仅指物质发展过程，也是一个问题。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
