Two features of these operations are apparent immediately: firstly, a large number of users must be able to operate at the same time without interfering with each other, and secondly, the distances over which the system must provide communication need not in general be great, since much of the system's operation will be either within the confines of a conurbation or along well-defined major vehicle trunk routes or railway lines.

这些部门的两个特征立刻就明显了：第一，很多的使用者必须能够在没有干扰彼此的情况下同时操作，第二，系统所能提供交流的距离大体上不需要太长，因为许多系统的操作是在大都市的边界里面或沿着明确限定的主要车辆主干路径或铁路线。

The results show that the dynamic force and thermal conditions of forming the squall line were the convergence of cold air from Mongolia cold vortex and the warm-humid air current before west trough to form the convectional system at moderate 3 scale; the rapid development and southward shift of MβCSs was caused by a strong unstable stratification and the shear line of suitable vertical wind; a heavy hail occurred after a vertical liquid water content over 65 kg/m^2 was firstly measured by weather radar; a sharp reduction of VIL indicates that a disaster strong wind will occur at soon.

结果表明：蒙古冷涡旋转下甩冷空气与西风槽前的暖湿气流汇合，形成中p尺度的对流系统是飑线形成的前期动力和热力条件；强的不稳定层结和合适的垂直风切变导致了MβCSs的迅速发展和南压；在天气雷达首次观测到垂直液态水含量值超过65kg/平方公尺后2h内出现了大冰雹；垂直液态水含量的突然减小标志着灾害性大风的开始。

To overcome the premature of simple genetic algorithm, the calculating efficiency of SGA is improved by the following two ways; Firstly, in order to ensure convergence of algorithm and reduce influence factor of convergence, elitist selection and adapted crossover and mutation operator are adopted. Secondly, because this study deals with finding minimize volume of structure, to quicken convergence of this problem, in line with mechanics criterion the paper carry out mutation to some genes in chromosome according to variations of internal force. This will let algorithms to search answer with our hoping directions.

针对基本遗传算法存在早熟的问题，本文主要从两个方面进行了改进，首先为了保证算法的收敛和减少影响算法收敛因素，采用了最优保护策略和自适应的交叉和变异算子；其次，由于本文研究内容涉及求结构最小体积问题，为了加快此类问题的收敛速度，本文结合结构优化中的力学准则，对个体染色体中的某一段基因按照内力变化进行变异操作，使得算法按一定方向进行搜索最优解。

Firstly, the difference of per capita GDP tends to convergence between the Western region and the Eastern region.

文章摘要：本文假设我国西部与东部地区的能源消费强度差异是西部与东部地区人均GDP差异的函数，然后同其他回归变量一起检验这两个变量之间的关系，并通过使用面板数据计量经济学模型进行实证估计。

The convergence problem in normed space has been analysised firstly in thistext. It is similar to weak convergence property.

在对区域分组方法的讨论中，本文通过对各种方法的优缺点的比较后认为，能够充分考虑各种经济增长影响因素的相似性，并提取分组过程中各因素重要性的分类回归树分析方法是较适合时间俱乐部趋同的区域分组方法。

Firstly, we adopted it to estimate the parameters in multicollinear linear regression model and proved the convergency of the algorithm.

文中提出一种病态分离的交互投影算法，用该算法对复共线的一般线性回归模型作出参数估计，并证明了算法的收敛性。

The author also brings his proposal about how to perfect the legislation of common bribery. He suggests: Firstly, in the general principles of criminal law, it should be prescribed definitely no matter the person who has identity or not committing a crime together which is constituted for their identity, the action belongs to common crime. Secondly, in separate principles of criminal law, the spirit of rule about the common bribery crime in "The conversazione summary of country court cognizance economy crime cases" put out by the supreme court of people in 2003 as well as "The notions of some questions about the suitable laws of transacting the bribery case in the supreme court of people and the supreme procurator of people" in 2007 should be put in the separate principles.

对如何完善共同受贿立法作者提出了自己的建议：建议在刑法总则中明确规定，无身份犯与身份犯勾结，共同实施因犯罪人身份而构成的犯罪，属共同犯罪，在分则中把2003年最高人民法院《全国法院审理经济犯罪案件工作座谈会纪要》以及2007年《最高人民法院最高人民检察院关于办理受贿刑事案件适用法律若干问题的意见》关于受贿罪共犯的规定精神纳入，分则中385条可以增加两款：与国家工作人员勾结伙同受贿的，以受贿论处。

In this thesis, we firstly introduce several class of discrete-time neural network models and the research progress of the neural networks. By Schauder fixed-point principle we prove the existence of an equilibrium (i.e. a fixed point) of a discrete-time neural network with generalized input-output function and by using the converse theorem of Lyapunov function we study the uniformly asymptotical stability of equilibrium in this discrete-time neural network with variable weight and give some sufficient conditions that guarantee the stability of it.
