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。

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。

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。

Taking the sediment discharge of the Lijin Hydrometric Station as input, increment of area and migration of shoreline of the present subdelta as output, by using the model of linear control system which is individual input and individual output, the author built the dynamic prediction model on the development and evolution of the present subdelta, and then predicted its development and evolution, and analyzed the influences of sediment discharge of the river on its development and evolution.

首先，以黄河利津站的来沙量为输入、现行黄河亚三角洲的面积和岸线增长为输出，采用单输入、单输出的线性控制系统模型建立了现行黄河亚三角洲发育演变的动态预测模型；然后，利用该模型对现行黄河亚三角洲的发育演变进行了预测，并据此分析了黄河来沙量对黄河亚三角洲的发育演变影响。

The results show that, dividing the evolution of RIN into three stages enables us to neaten the research results of the theoretical circle on RIN evolution reasonably, accords with the real situation of RIN development and provides results for the further study of the evolution of RIN.

结果表明，将RIN的演化分为三个阶段，能够比较合理地整合理论界在RIN演化上的研究成果，也比较符合RIN发展的实际情况。

Salt is good, but if the salt becomes flat and tasteless, with what do you season it?

14：33 盐本是好的，盐若失了味，可用什么叫它再咸呢？

He reiterated that the PLA is an army of the people under the leadership of the Communist Party of China.
