This dissertation investigates the construction of pseudo-random sequences (pseudo-random numbers) from elliptic curves and mainly analyzes their cryptographic properties by using exponential sums over rational points along elliptic curves. The main results are as follows:(1) The uniform distribution of the elliptic curve linear congruential generator is discussed and the lower bound of its nonlinear complexity is given.(2) Two large families of binary sequences are constructed from elliptic curves. The well distribution measure and the correlation measure of order k of the resulting sequences are studied. The results indicate that they are "good" binary sequences which give a positive answer to a conjecture proposed by Goubin et al.(3) A kind of binary sequences from an elliptic curve and its twisted curves over a prime field F_p. The length of the sequences is 4p. The "1" and "0" occur almost the same times. The linear complexity is at least one-fourth the period.(4) The exponential sums over rational points along elliptic curves over ring Z_ are estimated and are used to estimate the well distribution measure and the correlation measure of order k of a family of binary sequences from elliptic curves over ring Z_.(5) The correlation of the elliptic curve power number generator is given. It is proved that the sequences produced by the elliptic curve quadratic generator are asymptotically uniformly distributed.(6) The uniform distribution of the elliptic curve subset sum generator is considered.(7) We apply the linear feedback shift register over elliptic curves to produce sequences with long periods. The distribution and the linear complexity of the resulting sequences are also considered.

本文研究利用椭圆曲线构造的伪随机序列，主要利用有限域上椭圆曲线有理点群的指数和估计讨论椭圆曲线序列的密码性质——分布、相关性、线性复杂度等，得到如下主要结果：(1)系统讨论椭圆曲线-线性同余序列的一致分布性质，即该类序列是渐近一致分布的，并给出了它的非线性复杂度下界；(2)讨论两类由椭圆曲线构造的二元序列的"良性"分布与高阶相关性(correlation of order κ)，这两类序列具有"优"的密码性质，也正面回答了Goubin等提出的公开问题；(3)利用椭圆曲线及其挠曲线构造一类二元序列，其周期为4p(其中椭圆曲线定义在有限域F_p上)，0-1分布基本平衡，线性复杂度至少为周期的四分之一；(4)讨论了剩余类环Z_上的椭圆曲线的有理点的分布估计，并用于分析一类由剩余类环Z_上椭圆曲线构造的二元序列的伪随机性；(5)讨论椭圆曲线-幂生成器序列的相关性及椭圆曲线-二次生成器序列的一致分布；(6)讨论椭圆曲线-子集和序列的一致分布；(7)讨论椭圆曲线上的线性反馈移位寄存器序列的分布，线性复杂度等性质。

The basic reason about the fact that rural teacher's question emerges, has probed into the reality social current situation of two yuan structure in urban and rural areas of our country in this text, Educating the resource distribution system to cause rural education funds serious shortage directly unreasonable and in urban and rural areasly under 2 yuan structure in urban and rural areas, Author think education funds countryside educate heavy obstacles most that face rural, Society that household register system under social structure of two yuan has caused between town and country too cuts apart, Make the identity of the rural teacher discriminated against, cause rural teacher's social status to be low, The income is unfair, the living benefits are unequal , various kinds of welfare treatment can not get the due rational.

关于农村教师问题产生的根本原因，本文从我国的城乡二元结构的现实社会现状进行了探讨，城乡的二元结构下的不合理的城乡教育资源配置制度直接导致农村教育经费严重短缺，作者认为，农村教育经费的严重不足是农村教育面临的最大障碍，还有二元社会结构下的户籍制度也造成了城乡之间的社会分割，使农村教师的身份受到歧视，致使农村教师社会地位低下，收入不公平，生活待遇不平等，各种福利待遇得不到应有的合理保障。

Then the propagation of an arbitrary nonideal optical beam is analyzed. In terms of the moment theorem, the performance of modes of BOR is analyzed from both points of view of geometry optics and diffractive optics. Comparing BOR with the resonators using plane mirror and spherical mirror or using plane mirror and aspherical mirror by finite element method, the design procedure for BOR is gave.

On the basis of forenamed, Chapter 4 put forward that cooperation system was a new way to push the dual economic structure"s conversion. This chapter was consisted of there parts, first, it proved that cooperation system was the inevitable choice of peasant; second, it introduced four steps to advance the dual economic structure"s conversion of our country; at last, it introduced other reformations which coincide with cooperationsystem.

第四章在以上分析的基础上，提出合作制是推进我国二元经济结构转化的新思路，包括三个方面的内容，一是论述了合作制是农民的必然选择，介绍了合作制的定义，分析了农民选择合作制的原因，并说明合作制可以解决我国传统解决办法的不足；二是介绍了以合作制推进我国二元经济结构转化的四部曲，这四部曲是一般过程，每个地区都可以根据本地的条件有所取舍；三是介绍了以合作制推进我国二元经济结构转化需要的配套改革措施，首先，要统筹城乡的制度建设，其次，一定要把政府的扶持和农民的积极自救相结合。

In the first part, the thesis mainly checks the concept of urban and rural dual structure, manages to give it a philosophic, definition and then lists various conducts of the contradiction. It also analyzes the subjective and objective reasons that cause the Chinese urban and rural contradiction, and dissect the contradiction抯 feature, history, current situation and influence. This part means to explain that China is a prototypic developing country with Chinese characteristic urban and rural dual structure co!~tradiction. The incisive contradiction exists mainly in seriously backward countryside. In the fields of economy, politics, culture etc, it badly affects and restrains our economy and society抯 sustained, rapid and coordinated development manifoldly and omnibearingly.

第一部分从考察城乡二元结构的概念开始，给予城乡二元结构以哲学定义，然后列举了我国城乡矛盾的种种表现，分析了我国城乡矛盾形成的主客观原因，进而剖析了我国城乡矛盾的特征、历史与现状及影响，旨在说明我国是典型的具有中国特色的城乡二元结构矛盾的发展中国家，城乡矛盾极其尖锐，主要表现为农村元严重落后，在经济、政治、文化等方面，多层次全方位地严重影响和制约着我国经济与社会的持续、快速、协调发展。

Based on the pseudobinary method and solute aggregation model of aqueous solution, a pseudobinary solute aggregation model for correlating the viscosity of water-organic solvent-salt solution is established. The model has been tested for ternary aqueous solutions saturated or unsaturated with salt. The average relative deviation is about 1.0%. The results are better than the pseudobinary local composition model presented early by authors.

The transformation of dual economic structure is a crucial point of the economic development in developing countries,but the exsiting studies didn't display the transform tendency of dual structure in theory.

促使二元经济结构转化是发展中国家经济发展的一个关键，然而，现有文献不能为二元经济结构的转化趋向提供有说服力的解释，这影响了人们对二元经济问题的认识及转化路径的选择。

The flow resistance of Ice slurry increases if the pipes obliquity increases. That means the ice slurry that in the level pipe has the largest flow resistance, the reason is: the gravitation make the flow became more and more foul-up, accordingly, lead to the increase of flow resistance. Sixthly, introduced all of the preparative tasks before we began the experiment, because we met many problems during the test, we had our own methods which could solve these problems. In this paper, problems and these methods were introduced.

随着管道倾角的增大，二元冰的摩擦阻力减小，也就是说相同条件下水平管道内的摩阻最大，这是因为重力的影响导致管道内二元冰和乙二醇分层现象更加明显，从而导致紊流程度增大，最终使得摩阻增大；第六，对二元冰蓄冷空调系统运行前的准备工作进行了介绍，由于在试验过程我们遇到了很多问题，针对这些问题，我们有自己的方法和解决办法，本文介绍了这些问题和相应的解决办法。
