In quantum mechanics,the evolution of a quantum state is a unitary evolution ,the evolution process can be described by an action of a unitary operator on the quantum state and the process is time reversible.

在量子力学中，态的演化是一个幺正演化过程，态的演化过程可以用演化算子对态的作用来表示，幺正演化过程是时间可逆的。

Therefore, the indicatrixes of the liquid segregation mainly with immiscibility are the saltatory variation type of REE model evolution and the sep arative feature of main-evolution trend line either with sub-evolution trend line or with composition point of Li-F granites in the diagrams of REE-n and La/Sm-La.

因此，不混溶为主的液态分离标志是稀土模式演化突变类型和Li-F花岗岩在REE -n、La/Sm-La图解中主演化方向线与次演化方向线或与成分点呈分离特点。

The first stage of evolution was thus the evolution of a matrix of self-generating complexity, which gave evolution a population of persistent things to work on.

因此，进化的第一阶段是自生复杂性的基体进化，它为进化提供了源源不断的进化任务。

There is a new scientific theory of evolution-the theory of cellular automata : A simple procedure could be evolving into complex patterns can be accurately and easily simulate a variety of complex phenomena, from the growth of snowflakes to the universe, such as the evolution of the theory of evolution -- but often overlooked all their background-environment system stability and the supporting role of the smart set!

有一种新科学进化论－元胞自动机理论证明：一种简单但可演变出复杂样式的程序能精确、轻易地模拟出各种复杂现象，诸如从雪花的增长到宇宙的演化－－－然而所有的进化论往往忽略了其背景－环境系统的稳定而智能的支撑作用！

Lizards is a major group of reptiles, which plays an important role in the evolution of the vertebrates. Studies on their evolution, especially the molecular and cytogenetical evolution, is of great significance to reveal the evolutionary history of reptiles and futherly that of all the vertebrates.

蜥蜴类是爬行动物的一个主要类群，在整个脊椎动物的进化中有承前启后的重要作用，对其进化的研究，尤其是分子和细胞遗传学进化的研究，对了解爬行类乃至于整个脊椎动物的进化史具有重要的理论意义。

There is no doubt that the pathways described by Behe are dauntingly complex, and their evolution will be hard to unravel. Unlike anatomical structures, the evolution of which can be traced with fossils, biochemical evolution must be reconstructed from highly evolved living organisms, and we may forever be unable to envisage the first proto-pathways. It is not valid, however, to assume that, because one man cannot imagine such pathways, they could not have existed.

Behe 描述的路径无疑是复杂得惊人，而且我们很难弄清楚其进化过，从化石中可以推测解剖学结构的进化过程，但生化进化却不同，必须从高度进化的生物入手，我们可能永远也找不到进化过程中最早的原始路径（proto-pathways ），然而也不可因为某人想像不出这样的路径，而假设他们不曾存在。

On the basis of Theory of Endowment and Ricardian Comparative Advantage Paradigm, this paper carry out dynamic empirical analysis on the forenamed phenomena on the aspect of evolution of factor endowment and technological progress. The result of our research shows that there exists prominent positive correlation between upgrading of Chinas exporting commodity structure and evolution of factor endowment and technological progress respectively, moreover, the upgrading attribute more to evolution of factor endowment than technological change.

基于要素禀赋论和李嘉图比较优势理论，本文从要素禀赋演进和技术进步两个方面对此进行了动态的经验实证，结果显示要素禀赋演进和技术进步均分别与我国出口商品结构升级存在显著的正相关的关系，并且，要素禀赋的演进构成了出口商品结构升级的主要原因，而技术进步的贡献相对较小。

SWOT analysis of constructing Three Gorges Area Sport Tourism Circle;2. In order to reveal the evolution process of Three Gorges area,a geomorphy evolution modeling is set up on the basis of DEM by using GIS technology,and a visual method of geomorphy evolution simulation is presented.

为揭示三峡地区地貌演化过程，利用GIS技术，基于DEM，建立起了地貌演化模型，提出了一种可形象直观地进行地貌演化模拟的方法，形象再现了50×104a前三峡地区的地貌形态，并对50×104a以来三峡地区地貌演化进行了过程模拟，结果表明50×104a以来，中部抬升幅度最大。
