It is very direct and powerful and can be used to construct more new exact solutions of nonlinear evolutionary equations in mathematical physics.

该方法直接而有效，通过适当的变换将非线性发展方程转化为易於求解的微分方程组，从而可用来构造非线性发展方程更多新的精确解。

The principle of maximal profit is the main factor as to whether to obey credit or not. The analysis of using a game theory model once and using it repeatedly arid the analysis of a game theory model with outside intervene and evolutionary game theory analysis lead to a conclusion that strengthening cooperation and the government's power of supervision and punishment, the truthfulness of information , and a sound credit mechanism are the basic solution to the credit problem in electronic commerce.

本文运用博弈的方法，对电子商务中失信产生的原因进行了分析，认为收益的最大化原则是决定是否守信的主要因素，并通过对一次博弈、重复博弈和有外部干预情况下以及进化论博弈模型的分析，得出进一步加强交易合作的持久性、政府监管和惩罚的力度、信息的真实性以及完善的信用制度，是解决电子商务信用问题的根本方法。

Currently, a rich variety of evolutionary tree reconstruction methods have been developed, which fall into three categories, distance based methods, maximum parsimony methods and approaches applying the maximum likelihood principle.

一个可靠的进化树推断不仅有助于了解生物的进化历史和进化机制，而且对生物医药学、计算分子生物学其他分支的研究具有重要意义。

However, for hill-climbing strategies to be guaranteed to find the global optimum the optimality landscape must be unimodal. Moreover, research has demonstrated that multiple maxima exist under the maximum likelihood principle. Therefore, hill climbing based evolutionary tree reconstruction methods often return local optima.

但是由于进化树的似然函数通常含有多个局部极优解，而爬山算法没有逃离局部极优的能力，因此基于爬山算法的进化树构建算法很容易陷入局部极优。

Others reject this dichotomy completely and anticipate a more evolutionary path, sometimes called "the new medievalism", in which the relentless advance of information technology results in the demise of the state as we know it.

另一些人根本反对这种两分法，他们预见世界会走上一条更具有进化性的道路，这条道路有时被称为"新中世纪主义"，根据这一理论，信息技术的节节进步将导致我们现有概念中的国家最终灭亡。

In the 1930s, Darwinian natural selection was combined with Mendelian inheritance to form the modern evolutionary synthesis, in which the connection between the units of evolution and the mechanism of evolution was made.

在上世纪30年代，达尔文的自然选择是孟德尔遗传结合，形成现代的进化合成，其中之间的联系单位的演变的机制和演变了。

Schematic diagram of the evolutionary stages involved in the differentiation of the linker histone into the H1 subtypes of metazoan species.

进化阶段的概要图表进入后生动物种的 h1 次类型之内在连接器 histone 的区别中牵涉了。

Macroevolutionary studies focus on change that occurs at or above the level of species, in contrast with microevolution, which refers to smaller evolutionary changes (typically described as changes in allele frequencies) within a species or population.

宏进化研究重点关注发生在物种水平或物种以上水平的变化；相反，微观进化指的是物种内的或群体内的、较小的进化改变（通常用等位基因频率的变化来描述）。

You can snipe the second and third union leaders from this position.

您可以鹬第二和第三工会领袖从这一立场出发。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
