查询词典 evolution

In the calculation,mutation factor and crossover probability are the random numbers subject to uniform distribution in some space,with the development of evolution,the length of space will adaptively regulate according to former evolution experience.

在该算法中，变异因子和交叉概率是在某区间上服从均匀分布的随机数，随着演化的进行，该区间的长度将会根据前些代的演化经验自动调整。

Owing to Wei-Norman decomposition＇s application being confined in a little time area, in order to obtain the Unitary evolution matrix at any time, a small division of time is proposed in this paper, and Wei-Norman decomposition is used in every small division to obtain the unitary evolution.

由于Wei-Norman分解适用的范围是小时间变化的邻域，为了求出量子系统在任意时刻的幺正演化矩阵，根据量子系统的特性，提出了对量子系统的控制时间进行分段，利用Wei—Norman分解来获得每段小时间的幺正演化矩阵。

E volution works pursuant to the length of time and differences are divided into micro evolution and macro - evolution.

演化方式可依据时间长短以及差异程度，分为「微观演化」与「宏观演化」。

Aiming at the foundation of Liu Shipei's literary viewpoints of evolution, namely, vulgarism and parallel prose, this article reviews it by two angles to language and vicissitudes of style, discovering that his literary viewpoints of evolution was only a sort of reasoning strategy, so his two standpoint of enlightening country and preserving Guoxue match respectively for vulgarism and establishing legitimacy for parallel prose.

文学进化观在近代文学观念中很值得研究，从梁启超和刘师培都可见这种文学观念的影响。而刘师培的进化文学观尤其复杂。本文从他立论的基础即俗语和骈文，从语言文字和文体变迁两个角度来讨论这个问题，认为他的进化文学观只是一种论证的策略，承认俗语和为骈文立正统分别合于他的启瀹齐民和保存国学两个立场。

Carl Zimmer: Whether it's the evolution of new kinds of influenza viruses, or the evolution of our own species.

卡尔·齐默：无论是新型流感病毒的发展演变，还是人类本身的进化历程，这些都深深吸引着我。

One kind of externality gets in touch with market division closely, produced by deepening of market division. In the frame of dynamic evolution of market division, which was put forward by Smith – Alin · Younger and developed by theory of endogenous economic growth, people draw the following conclusion. Externality exists all along, associating with institutions of market division. Evolution of institutions reduces the degree of externality partly, but furthers division of labor simultaneously, which initiates new externality. It moves in cycles like that.

杨提出的，新增长理论加以发展运用的市场分工制度动态演进的框架下，人们会发现外部经济现象伴随着市场分工制度始终存在，制度演进在一定程度上降低外部性的程度，但由此同时促进分工，而又产生新的外部经济性，如此循环往复。

The current teaching situation of organic evolution in America high school tells us: be on your guard against antievolution thought and persist the theory of evolution.

从我国新一轮基础教育课程改革确定的课程目标入手，从三方面探讨了生物进化在高中生物学课程中的重要价值，并以此为切入点，分析生物进化课程内容的设计。

One of the points that is repeatedly stressed in the book on evolution by Ardea Skybreak is that the process of evolution can only bring about changes on the basis of what already exists….

Ardea Skybreak在其关于进化论的书中反复强调的一点是，在进化过程中，进化只能给那些已经存在变化基础的东西带来变化…自然界中的进化通过现实和现有限制（或者换句话说，现有必要性）中已经出现的相关变化得以实现，而且也只能如此。

The paper is organized as follows. In chapter 2, we introduce some concepts about SEA, the abstract SEA model and the convergence definition of algorithm. In chapter 3, we describe firstly the evolution of PMA as an abstract stochastic process, and by characterizing axiomatically the properties of the fundamental selection and evolution operators, we conclude that PMA is essentially a kind of SEA.

本文结构安排如下：第二章介绍了模拟进化算法的一些基本概念、形式化随机过程描述以及收敛性定义；第三章对改进后的 PMA 各操作作了抽象定义，得到了 PMA 的形式化随机过程描述，并公理化地证明了各操作算子为选择或繁殖算子，从而得出 PMA本质上也是一种模拟进化算法；第四章先对选择算子特征数定义作了适当改进，并通过各进化算子的具体特征数指出，如果 PMA 不采取任何执行策略时，算法本身并不收敛。

In this area, the evolution history of the main faults including Zhen①fault, Zhen②fault and Zhen②′fault is burring. Through the analysis of structural evolution and quantitative research of fault activity, the development history of the three main faults is verified. It also could be supported by structural physical simulation.

南部断阶带是高邮凹陷南部的一个二级构造单元，长期以来真①、真②及真②′等主干断层的发育历史模糊不清，本论文通过对构造演化的分析及对断层活动的定量研究重新厘定了三条主干断层的发育历史，并利用构造物理模拟实验对其进行了验证。
