Level set method introduced by Osher and Sethian is a numerical method, which translates the problem of evolution of 2-D (3-D) close curve into the evolution of level set function in the space with higher dimension. Level set is an accurate and steady algorithm; it can treat with the change of topology naturally.

水平集方法是由Osher和Sethian提出的一种数值计算方法，它将二维的闭合曲线的演化问题转化为高维空间中水平集函数曲面演化的隐含方式来求解，具有拓扑结构可自然变化、计算精度高、算法稳定的特点。

通过对神经元群体而不是神经网络群体进行进化设计，显著地减轻了计算量，同时利用生物免疫原理中的浓度机制和个体多样性保持策略进行免疫调节，有效地克服了未成熟收敛现象，提高了群体的多样性，从而加快优化设计速度。

From the evolution, Id o the research based on the feature of the evolution of the twifold govern structure in the grass-route society in modern-time China. Discuss power network and land relation and calamity and population press. I tried to reveal the specific of modern-time China and the logical relationship with the formation of the party of the early-stage in China.

从基层社会的双重统治结构发展演变入手，并对基层社会的权力网络、土地关系、自然灾害、人口压力等问题进行了探讨，目的在于通过明晰中国的基层社会的自身特点，揭示中国基层社会的特殊性与中国早期政党产生之间隐含着的逻辑联系。

Different from the sole-population evolution, the multi-population evolution partitioned the initial population into umpty sub-populations. Each sub-population evolved independently according to certain schema. In proper situation, the sub-populations would exchange information among themselves, to maintain the population diversity.

与单一种群进化不同的是，多种群进化将初始种群划分为若干子种群，各个子种群按照一定的模式独立进化，适当的时候在子种群之间交换信息，从而维持种群的多样性。

It is divided into three parts: In Part 1, based on mumerical simulations with the pseudo-spectral method, we introduced some new concepts such as the response speed of soliton interaction, the symbol correlation range, etc., and simplified the evolution problem of general soliton sequencies into the evolution problem of finite equivalent classes of words on a unoriented circle, and then gave out the count formula of the equivalent classes by Pó1ya theorem.

全文分三个部分：第一部分以利用拟谱方法所做的大量数值模拟为基础，分析光纤孤子通信系统中一般编码孤子序列的演化性质，提出孤子相互作用传递速度概念，通过考察通信系统的实际情况，引入码元关联长度K，把一般编码孤子序列的演化问题归结为无定向圆环上有限个不等价码字的演化问题，最后利用Pólya定理解决了不等价码字的计数问题。

The sodium sulfate was used as the electrolyte instead of sodium chlorid. The results elucidated the low pH of EOW was mainly caused by oxygen evolution and the high ORP was mainly generated by both chlorine and oxygen evolution.

用NazSO_4代替NaCl作电解质进行电解，结果表明酸性氧化电位水的低pH主要是由析氧反应造成的，而高ORP值主要是由析氯反应和析氧反应共同造成。

The overvoltage difference between oxygen evolution and chlorine evolution of optimized Ti/SnO_2-Sb_2O_3-CeO_2 electrode was the biggest,that is to say, it is more proper to be used for electrochemical oxidation of ammonia wastewater when there exist chlorin ion.

其中，经过优化的Ti/SnO_2-Sb_2O_3-CeO_2电极析氧析氯电位相差最大，反应出其性能优于其他电极，更适合用于含有氯离子情况下电氧化含氨氮废水的处理。
