We have get some interested results: such as, extended the auxiliary equation method, and which is also used to find the exact solitary wave solution of some nonlinear evolution equations.

如对辅助方程法进行了扩展，并利用两类新的辅助方程的解给出了一些非线性发展方程的新的精确孤立波解。

By using the solutions of a new auxiliary elliptic equation,a direct algebraic method is proposed to construct the exact solutions of some nonlinear evolution equations.The main difference between this method and previous auxiliary elliptic equation methods is that the balance order becomes smaller after using the new auxiliary elliptic equation.Therefore,the derived algebraic equations are greatly simplified.

利用一个新的辅助椭圆方程将求解非线性发展方程精确解的问题转化为一个代数方程组进行求解，与已有的辅助椭圆方程法的主要不同是，应用这一新的辅助椭圆方程后降低了平衡次数，减少了所得的代数方程组的个数和方程的项数，从而大大地简化了代数方程组的求解。

The results of numerical simulation reveal that the resistance to liquefaction of sands increases as the angularity of particles increased, and the micro_mechanism is related to the average coordination number of sample. It also found that the numerical sand sample made from randomly mixing multiple shapes of sand can quantitatively reflect the regularity of fabric evolution of sands during liquefaction.

结果表明，颗粒棱角度越大，试样抗液化能力越强，其在细观机理上与初始平均接触数大小有关；随机混合仿真试样可以从定性角度反映实际砂土振动液化过程中的细观组构演化规律，为今后进一步的定量研究奠定了基础。

There was no notable difference in avifaunal zoogeographical pattern of China before and after 30 years by cluster analysis. The accordance of present analysis and zoogeographical region division in Cheng(1976), Zhang(1991), and Cheng(1997)'s reflected long term stability in evolution of avifauna.

鸟类区系的动物地理分布格局聚类分析结果，在30年前后没有明显差异，和郑作新（1976），张荣祖（1991）以及郑作新等（1997）的动物地理区划结果一致，反映了鸟类区系演化的长期稳定性。

It accounts for more than 64% of species recorded in China. The study was the most comlplete , systematic work about birds in Yunnan and recorded the most species of birds in Yunnan at present. The recources status and geographical distribution of birds in Yunnan were deeply studied, and the characters and evolution tendency of avifauna in Yunan, geographical division of birds in Yunnan were discussed.

本项目通过系统的分类和区系研究工作，共描记云南鸟类848种(1074种和亚种)，占中国记录鸟类种数的64％以上，是目前记录云南鸟类物种最多、最全面和最系统的工作；并在深入研究云南鸟类资源状况和地理分布的基础上，探讨了云南鸟类的区系特征及其演化趋势、三级地理区划。

With the support of the project, the study completed the classification to passerine birds in Yunnan, summarized their habitat environment, geographical distribution; and analyzed the characters and evolution tendency of avifauna in Yunnan, geographical division of birds in Yunnan. The project was successfully completed. As production of the study, the book of "The avifauna of Yunnan China, Vol.2: passeriformes", three articles in periodical journal, two articles in national meeting proceeding and three articles in international meeting proceeding were published.

在该项目的支持下，通过对云南省雀形目鸟类的分类整理工作，以及栖息地生境、地理分布、区系组成和演化、地理区划等总结分析，完成和出版了《云南鸟类志下卷雀形目》，发表期刊论文3篇，国内学术会议论文2篇，国际学术会议论文3篇。

Therefore, this chapter, in the first place, discusses the axiomatization of theory ofevolution and introduce in detail Williams' axiomatic system about evolution. Insecond place, it discusses the dissipative theory and the hypercycle theory. Thisdiscussion is actually about a kind of semantic which is the molecular model.

因此，在这一章，首先，对进化理论的公理化形式进行讨论，详细介绍了Williams进化论的公理系统；其次，讨论耗散结构理论和超循环论，实际上是讨论了关于进化论的演绎公理系统的一种语义或分子层次的模型。

Hence, the dissipativetheory and the hypercycle theory attempt to construct a substantialistic model ofundermost hierarchy which can satisfy axiomatic system of evolution, that is it isa molecular system which can proceed self-replication or autoreplication.

因而，耗散结构和超循环论，给出的是满足进化公理系统的最低层次实体模型（能够进行自我复制的分子系统）的分子演化过程的动力学描述。

These members had become people of a flock of leading sheep series in SEO industry at present, average person can optimize a website with them for the standard, feel the word of these people is more authoritative, blind follows suit the order that brought about SEO industry to compare a disorder now and Baalism, affected the normal evolution of SEO badly.

这些成员现在已经成为SEO行业里的一群领头羊系列人物，一般的人都会以他们为标准来优化网站，觉得这些人的话都是比较有权威的，盲目的跟风导致了SEO行业现在比较混乱的秩序和偶像崇拜，严重的影响了SEO的正常发展。
