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.

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.

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.

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。
