In 1984, Sun Jingxian put forward the conception of invariant set of descending folw in his doctor degree thesis, which gave an another methods to determine a critical value.

这些定理给出了确定临界值的一个基本手段。1984年，孙经先在他的博士论文中提出了下降流不变集的概念，给出了确定临界值的另一手段。

Because he had a bad mood, and then decreased resistance to colds, and lassitude Your phone number.

因为这些他们心情不好了，于是抵抗力下降感冒了，精神不振开车撞人了。

In recent years, with the development of the micro-electronics technique, the price of GPS receiver have been greatly falling , and as a result of the United States closing SA to stop limiting the public position accuracy of GPS , the GPS positioning accuracy have improved greatly in public field. All this consumedly promote the development of GPS in public field, and especially in the vehicle navigation field , GPS shows its superiorly navigation performance.

近年来随着微电子技术的发展使得GPS接收机的价格大幅度下降，同时美国提前关闭SA停止对民间用户精度的限制使得GPS民用定位精度有了很大的提高，这大大促进了GPS在民用领域的发展，尤其是在车辆导航领域，GPS系统充分展示了它那优越的导航性能。

It was known that the mass transfer in the packed column was influenced by the "natural"flow. In this paper, the process of forming the"natural"flow was analyzed. By changing the geometric dimensions of the structured packing, the maldistribution of the"natural"flow could be decreased.

以往的研究表明，填料塔传质效率的下降与液体"自然流"的形成有关，本文通过研究液体的微观流动，对规整填料塔内"自然流"形成的原因进行了分析，指出了填料结构与"自然流"形成的内在关系，并提出了改变填料结构，以降低"自然流"不均匀分布的方法。

This method keeps the advantages of steepest descent method and overcomes the phenomenon of zigzag, and thus increases convergence rate.

此方法既保持了最速下降法的优点，又消除了其锯齿现象，有效提高了计算速度，与其它有关的这一类算法相比，最佳方向法也显示出计算简单、占用计算机内存空间少和收敛速度快的优点。

The influence of some rnodified genetic algorithms on searchspeed is also examined. Some genetic operations suitable to the optimization technique areobtained, therefore, a novel way of solving a class of optimizations of functions that cannot be realized using the method of steepest descent is proposed.

文中还分析了一些改进的遗传算法对于该问题搜索速度的影响，得到了适于解决此问题的合理的遗传操作，从而为有效地解决最速下降法所不能实现的某一类函数代化问题提供了一种新的途径。

A"bit-mismatch"squarer and a"digit-serial"polynomial multiplier have been designed for finite field arithmetic and the modular inverse in GF (2〓) can be calculated under the combination of the squarer and the multiplier. Based on the Montgomery method for the elliptic curve scalar multiplication, a new improved process has been put forward in the thesis.

论文改进了标量乘法Montgomery算法流程，利用寄存器间的数据交换，将0和1两种情况下的中间结果"点加一倍点"操作统一起来，简化了控制流程，使关键路径延时下降，而且减少了运算单元输入输出的连线逻辑。

Although the product strategies, marketing channels and promotion tactics boosted the sales of finance product in some degree, finance product turnover keeps on the decline. Principal decision makers of Dalian branch of SPDB hold marketing meeting to discuss how to conduct the marketing campaigns about finance products, but disagreements appeared in various aspects of marketing strategies. In caseanalysis, Dalian branch of SPDB made analysis and identification of different target markets by means of market segmentation.

在理财产品销售中采用的产品策略、渠道策略、促销策略，虽然对理财产品销售起到了一定的作用，但是理财产品销售收入在持续下降，就如何开展理财产品的营销工作，浦发银行大连分行的几位主要决策人召开营销会议进行讨论，但是对市场营销策略的各方面产生了分歧；最后，在案例分析中，浦发银行大连分行通过对客户的市场细分，进行了银行不同目标市场的分析和定位。

Based on equaling the semi-rigid connecting as the reduction of member end section bending stiffness,an optimization equivalent method is put forward on the principal of minimizing the error term between stiffness matrix of fined model and one of equivalent simple model.In this dissertation,structural fatigue cumulative damage and residual life assessment of wind-induced fatigue safety prewarning system is studied.S-N curve method and fracture mechanics method for fatigue analysis are discussed.

本文建立了高耸塔架结构中广泛使用的螺栓节点板联结节点的精细有限元模型，提出了一种优化等效的方法，以刚度矩阵的误差最小为等效原则，在把节点处杆件的半刚性联接等效为杆端截面抗弯刚度下降的基础上，得到了螺栓节点联结杆件的精细有限元模型与简化有限元模型的等效关系。

Since 1997, the trend of deflation has been appeared in our country , the commodity retail price index, the residents consumption price index and the production material trade price index all have been appeared to be negative growth, the increase extent of money supply and the money circulation velocity also have been appeared to decline.

1997年以来，我国出现了通货紧缩的趋势，商品零售价格指数、居民消费价格指数、生产资料批发价格指数均出现了负增长，货币供应量增幅和货币流通速度也出现了下降的趋势。
