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。

First, based on the analogy of the mathematical expressionbetween the propa gation of EM wave and that of seismic wavein a horizontal stratified earth, the re flectivity and transmissionformulation for EM plane wave propagating incident nor malto the layers are derived, the formulation with relation to pseudo-impulse is discussed and pseudo-impulse response is compared with impulse response of re flection seismology.

作者首先基于电磁波与地震波在水平层状介质中传播特征在数学形式上的相似性，推导了垂直入射平面电磁波在层间反射与透射传播函数，并讨论了它们与伪脉冲的关系，与反射地震学中脉冲响应作了对比。

Non-character includes less orthographical information than pseudo-character, so it is easier to make decide in lexical decision task than pseudo-character and that non-character is decompounded.

和假字比起来非字虽然包含的正字法信息更少，但是可能正因为此原因，非字在词汇判断任务中更为容易，从字形上就可以判断出来，从而更容易导致对非字的分解加工。

In this paper, the pointwise pseudo-orbit tracing property is defined on a compact metric space, and it is a generalization of pseudo-orbit tracing property.

Because you can update the data at once and not send the world matrices one by one, as it is done by pseudo instancing, it would be still faster than pseudo instancing.

由于你可以一次更新数据，但不能逐个发送 world matrix ，就像伪实例化做的一样，但这还是比伪实例化快一些。

Based on modeling each frameof the sequence using TIP technique, we reconstruct the pseudo model of the scene aboutthe image sequence by mosaicking the models to a global model or using a switchingstrategy; then walkthrough can be done in the pseudo model freely.

在对序列图像的每一幅都建模的基础上，我们通过模型拼接或者模型切换生成，建立有关图像序列场景的伪模型，然后实现了在伪模型内任意漫游。

Hence we conclude that there is positively no real Atman; that there are only various consciousnesses which, since before the beginning of time, have followed one another, the subsequent one arising with the disappearance of the antecedent, and thus a continuous series of causes and effects (karmic seeds－actual dharmas－karmic seeds) is formed; and that, by the perfuming energy of false thinking, an image of a pseudo-Atman arises in the consciousness, and it is this pseudo-Atman which the ignorant take for a real Atman.

因此可以确定的说：一定毫无实实在在的我；只有诸识在自己无始开始存在以来，於分段生死中相续不断，自己的存在无始以来前灭后生，在因因果果、果果因因中相续不断，因著业力的虚妄熏习，出现假我的种种现象，就误以为有我，故无知的愚者自以为有ㄧ个实我。（韦达在此将《成唯识论》的「诸识」翻成「几种不同的识」，指的是种子识、末那识、眼、耳、鼻、舌、身、意等八个识，在不同时空分段生死中，所起的外延与内涵、作用不同，所以才用「不同的」various一词。其次，他把「无始时来」翻成「since before the beginning of time」，就尚德对佛法的了解而言，佛法所指的「无始」不是指「时间的本身」，而是指众生生命开始的那个时刻，叫做「无始」。----------译者

The results also reveal that there are no subsequent memory effects in pseudo-character. It seems that processing of pseudo-character did not activate preexisted mental representation in memory.

实验结果还显示，在假字中没有发现显著的相继记忆效应，可能在假字加工过程中没有明确通达记忆中预存的心理表征，而这种心理表征的通达是相继记忆效应产生的前提。

The compound solution performs as pseudo-fictile fluid, and its visual viscosity is reduced when the shearing velocity increases. The higher the cationic degree of CPAM, the more apparent the rarefying behavior of the polymer-surfactant complex, but it still is pseudo-fictile fluid. In addition, such factors as the molecular weight of CPAM, temperature and PH value etc, have different effect on the properties of the mixed solution, including its visual viscosity, conductivity, rheological behavior and so on.

CPAM／SDS复合体系的表观粘度随剪切速率的增大而下降，即具有剪切变稀行为的特性，表现为拟塑性流体：CPAM的阳离子度越高，它与SDS形成复合体系剪切变稀的行为越明显，但体系的流动类型不发生变化，仍为拟塑性；随着CPAM分子量的提高，复合体系的非牛顿性增强；温度的升高将导致复合体系的粘度显著降低，非牛顿性减弱；对于SDS用量低于等电荷当量的复合体系，pH值的变化对其流变性的影响不显著。

In order to overcome those limitations, and on the premise that the receiver can measure the pseudo-range between the user and satellite and with the help of barometer, this paper put forward the pseudo-range integration model of RDSS and the strap-down inertial navigation system with high precision clock, rubidium clock being the internal clock of the RDSS receiver.
