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.

In order to construct a scientifical, fair and reasonable system of social income distribution, we have to deepen the reform of the system of income distribution and standardize the order of income distribution. The income distribution of civil servants is an important part of the income distribution of the whole society.

持续的收入分配不公，已经沉淀了许多社会矛盾，构成了巨大的社会张力，有些甚至到了一触即发的严重程度，对改革的进一步深化以及和谐社会的构建产生了相当大的影响。

In the article we at first discuss the kind of stock log-return distribution. We find that 7 kinds function can describe stock log-return form their works: Gausses of normal distribution, Levy distribution, t distribution, spike attitude distribution, random fluctuating model, ARCH-GARCH model, divide shape Brownian movement .

Distribution according to work; distribution according to the production factor and other distribution. However, if the distribution of personal income should be conducted in accordance with the factor of production and the other means, there are multi-types of concrete modes of distribution, that to distribute somewhat one makes contribution based on labor value chiefly; the structure of ownership; the propr...

按生产要素分配和其他分配方式又各有多种具体形式；按生产要素分配即生产要素按贡献参与分配的依据主要有劳动价值论、所有制结构、生产要素所有权和市场经济；个人收入应划分为合法收入和非法收入两类，国家应保护合法收入，打击和取缔非法收入。

There are three difference formats in this thesis. They are backward difference, Crank-Nicolson"s difference and Galerkin"s difference.

Between the Chinese and American culture difference has accomplished the China and America classroom instruction difference, but this kind of difference comes from in the Chinese and American education idea and the educational system difference, the China elementary education attention knowledge accumulation and instills into, the attention trains the student to ask the same thought and the attention trains the student to the knowledge itself grasping, but US pays great attention to actually trains the student to carry on the solution actual problem using the knowledge ability, the attention trains the student to the knowledge innovation and the development, also the attention raises the student criticalness thought and the divergent thought.

中美文化之间的差异造就了中美课堂教学的差异，而这种差异来自于中美教育理念和教育制度上的不同，中国基础教育注重知识的积累和灌输，注重培养学生的求同思维和注重培养学生对知识本身的掌握，而美国却注重培养学生运用知识进行解决实际问题的能力，注重培养学生对知识的创新和拓展，且注重培养学生批判性思维和发散性思维。

The difference schema of the initial boundary value problem was converted to the step-by-step form,which was similar to the difference schema of the initial value problem.It is concluded that the difference schema satisfying the Von Neumann condition is a stable schema,and that,under the consistency condition,such stable schema is convergent.Moreover,with error estimate expression for the difference approximation to the classical solution,the linearity condition is unnecessary.

引入反投影算子将发展方程初边值问题的差分格式转化为与初值问题差分格式类似的逐步推进的形式，从而得出：满足Von Neumann条件的差分格式是稳定的格式；在相容条件下，差分格式若稳定(或满足VonNeumann条件)则格式收敛，且对古典解的差分逼近有误差估计式，不再需要线性的条件。

Goodbye Alice in Wonderland Jewel It's four in the afternoon I'm on a flight leaving L.A. Trying to think about my life My youth scattered along the highway Hotel rooms and headlines I've made a living with a song Just a guitar as my companion Wanting desperately to belong Fame is filled with spoiled children They grow fat on fantasy I guess that's why I'm leaving I crave reality So goodbye Alice in Wonderland Goodbye yellow brick road There is a difference between dreaming and pretending I did not find paradise It was only a reflection of my lonely mind searching For what was missing in my life I'm embarassed to say the rest is a rock and roll cliche I hit the bottom when I reached the top I never knew it was you who was breaking my heart I thought you had to love me You did not Yes a heart can hallucinate If it's completely starved for love Can even make monsters seem like Angels from above You forged my love like a weapon And turned it against me like a knife You broke my last heartstring But you opened up my eyes So goodbye Alice in Wonderland Goodbye yellow brick road There is a difference between dreaming and pretending That was not love in your eyes It was only a reflection of my lonely mind wanting what was missing in my life And growing up is not the absence of dreaming It's being able to understand the difference between the ones you can hold And the ones that you've been sold Dreaming is a good thing cause it brings new things to life Pretending is an ending that perpetuates a lie Forgetting what you are Seeing for what you've been told Well, truth is stranger than fiction And this is my chance to get it right Life is much better without all of your pretty lies So Goodbye Alice in Wonderland You can keep your yellow brick road there is a difference between dreaming and pretending There's not tears in my eyes It was only a reflection of my lonely mind searching It was only a reflection of my lonely mind finding I find what's missing in my life

再见，梦游仙境的爱丽丝下午四点我在飞离洛杉矶的班机上试着去理顺生活我的青春散落在公路上就宿于各地旅馆，无数次登上头条我以一首歌成功立足吉他为伴我强烈渴望被接受和认可有名的人大多是被宠坏的孩子幻想使我们贪求无餍我猜想这就是我离开的原因我渴望活在现实里因此再见吧，梦游仙境的爱丽丝再见吧，黄砖路梦想和矫饰不同我没有找到天堂那不过是我孤独心灵的一种反映，我渴望找到生命中缺失的东西尽管尴尬，我不得不说一句摇滚乐界的陈词滥调当我的事业达到顶峰时，我的心情跌落到了谷底我从未想过，会是你让我心碎我以为你一定会爱我但你没有是的，如果心对爱饥渴它会产生幻觉，认假为真它甚至可以把妖魔认作下凡的天使你把我的爱练成一种武器然后把它像刀子一样捅向我你断了我最后一根心弦但你让我看清了现实因此再见吧，梦游仙境的爱丽丝再见吧，黄砖路梦想和矫饰不同你眼里的不是爱不过是我孤独心灵的一种反映，我努力寻找生命中缺失的东西成长不是梦想的消失而是一种能分辨你坚守的东西与导致你被骗的东西的能力并且梦想是个好东西因为它给生命带来新鲜事物但矫饰是一个终结它使谎言无限期地延续忘了你是谁只着眼于人们告诉你的那些东西真实比虚构更奇怪而这是我求取真实的机会没有那些漂亮的谎言，生活会变得更美好因此再见吧，梦游仙境的爱丽丝你可以留住你的黄砖路梦想和矫饰不同我眼里的不是泪水不过是我孤独心灵的一种反映，我意识到不过是我孤独心灵的一种反映，我意识到我已经找到了生命中缺失的东西
