The thesis also draw several conclusions as follows:(1) Orthogonal experiment design method can be viewed as a special case of genetic algorithm, i. e. a genetic algorithm with a fixed initial population, an oriented-mutation operator and one evolution epoch.(2) In terms of running steps, genetic algorithm is more complex than orthogonal experiment design method.

论文首次对正交试验设计法和遗传算法这两种独立发展起来的方法进行比较研究，提出(1)正交试验设计法是遗传算法的一种特例，即是一种初始种群固定的、只使用定向变异算子的、只进化一代的遗传算法；(2)遗传算法产生的优化解优于正交试验设计法产生的优化解，且遗传算法处理交互作用项的效率高于正交试验设计法；(3)遗传算法的步骤比正交试验设计法复杂，所需的试验次数也要多。

Based on a component model of application system in which three types of the basic components are discussed, this paper first focuses on the "semantic" interoperability among components, and presents a Primitive-Semantic component constructing method through a semantic model to deal with the semantic interoperability while the communication protocol among components doesn't exist. It then presents a composable Distributed Virtual Reality Component-Based Architecture, including its key mechanism and algorithms.

指出分布式虚拟现实系统中存在的3种基本构件；重点讨论构件的"语义"互操作问题，通过建立构件的语义模型，提出一种原语-语义构件的构件构造方法，该方法可以解决不存在通信协议情况下的构件之间"语义"互操作问题；给出一种支持可组装的分布式虚拟现实应用系统的基于构件的体系结构以及其中的核心机制和算法。

The first is Gramineae, including 37 species and 15 genera. The second is Compositae including 36 species and 18 genera.

排在前三位的分别是：禾本科，15属，37种；菊科，18属，36种；豆科，8属，20种 2。

The main families are Gramineae (10 species), Compositae (7 species), Leguminosae (5 species).

主要包括禾本科(10种)、菊科(7种)、豆科(5种)。

The invention provides compositions and methods, for reducing one or more symptoms of an autoimmune disease, inflammatory disease and/or transplant rejection, by the administration to a subject in need thereof a pharmaceutically effective amount purified compound of any one of Formulae A-E.

本发明是相关于药物组成物及相关方法，确切地说，是相关于通过对病体的不同需要按配方A-E中的一种对病体给药以一定量纯化的组成物，来减弱一种或多种炎性疾病，自体免疫性疾病，和移植排斥引发的一种或多种症状。

Another way of saying this is to state that the only way for a particular compound or function to survive in the long run is for it to be a product of another compound or function.

还有另外一种表述方式，即一种特殊化合物或功能长期存在是因为它是另一种化合物或功能的产物。

A compound is a substance that can be split into two or more elements.

一个化合物是一种物质，它可以分解成两种或两种以上的元素。

Two different Fabry-Perot cavities have been adopted: plane mirror cavity and confocal concave spherical mirror cavity.

采用了两种不同的Fabry-Perot腔体结构：平面腔镜结构和对称共焦球面腔镜结构；首先进行了理论分析，得出两种结构中折射率变化与干涉条纹变化的关系，然后分别对两种腔体结构下的测量系统进行实验研究，都可以探测到10-5量级的折射率变化量，结果基本令人满意。

Marius turned over all this confusion of ideas in his mind, passing from one to the other, and moved by all of them. Hence arose a profound trouble.

所有这些想法在马吕斯脑海中混乱地上下翻腾，从一种想法转到另一种，每一种都使他激动，他因而极端惶惑。

This is not so much a kind of esthetical psychology phenomenon, as a kind of social psychology phenomenon. If considered those non- esthetical factors existing in the process of the esthetical connoisseurship, we can discover that this actually is the phenomenon of aesthetical "pseudo-identity"

这不仅是一种审美心理学现象，而且更是一种社会心理学现象，如果考虑到那些存在于审美过程中的非审美因素，就会发现，这其实可能是一种"虚假审美认同"现象。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
