The author first traces the evolution of the practice and theory of multiculturalism, delineating its course from an assimilationist approach that aimed at the perpetuation, transmission, and promotion of the cultural beliefs of the dominant community to an integrationist approach that aimed for equal opportunity within a culturally diverse and mutually tolerant society to cultural pluralism, which accepts and actively promotes diversity.

多元文化科学教育是在多元文化教育理论的框架里发展起来的一个新的分支研究领域，因而它是科学教育理论和实践的重要组成部分。目前，多元文化科学教育的知识体系还不够完善。从已有的知识体系来看，多元文化科学教育包括人们对少数民族群体特征的认识和对其文化与科学的理解。

Not only will I be acquiring practical knowledge in my specific field, I will also be gaining expertise that is in great demand by industrial sectors in China.

不仅我会获得实用的知识，在我国特定领域，我还会获得知识即是需求大的工业行业中。

The knowledge based engineering system is the specific concretion of knowledge engineering in many respects.

基于知识的工程系统是知识工程在各个领域的应用。

After a brief summary on data mining and rough set theory, the research works in the thesis can be descript as follows: 1. To the problem that finding rules in enormous data is very timeconsumable and the expansibility of existed algorithms is not very good, the thesis proposes a new method to discompose large data table based on the concepts of positive region and the importance of attribute in rough set theory.

Rough集理论是一种新型的处理不确定性知识的数学工具，围绕着数据挖掘领域存在的问题，本文利用Rough集理论与Rough分析工具，提出若干解决方案，同时在具体处理问题过程中引入了信息理论、因子分析等方法，与Rough分析结合使用，讨论了Rough集技术在知识发现、关联规则挖掘、模式分类以及数据清洗等问题中的应用。

Based on the heterogeneous knowledge units, the system can be used for real time meteorological data quality controlling. by use of the ontological analyzing technique, the entities and their relationship are analyzed to position the knowledge point for data checking and to improve the efficiency of knowledge acquiring from expert's experience.

该系统应用领域本体分析技术，集成多方面专家的经验知识，确定气象观测数据质量控制的知识点，通过异构知识体之间的协作，实时推断气象观测数据的正确性，实现对地面气象观测数据的实时自动错误检测、警示并给出更改建议。

Comparatively, the concepts of KM and web2.0 are new. The study of knowledge management in education field is a hot sport and very meaningful, it is useful to study it both from the theory and implication.

知识管理和web2.0都是较新的研究领域，对知识管理在教育中应用的研究，属于学科前沿，从理论价值和实际应用上讲，具有很大的现实意义。

IAFL-SCS consists of four main parts: Input vector distributor and three sub-FLC named Equivalent roll FLC , Equivalent yaw FLC , Equivalent pitch FLC respectively. It has very simple and uniform topology structure and physical meaning of parameters in IAFL-SCS is unprecedentedly clear. Simulation results prove IAFL-SCS has good control performances and can be used in most of BTT missiles directly without great changes.

更进一步，针对现有BTT导弹稳定控制系统设计技术的局限性，以近年来兴起的模拟进化最优化技术为主要手段，结合专家知识导向，创造性地进行了BTT导弹稳定控制系统自动设计的研究，完成了专家知识导向BTT导弹稳定控制系统自动设计方法的工程应用，开辟了这一国内空白的研究领域，国际上也没有看到类似的文献资料。

This paper aims to analyzing the reasons of the difficulties in knowledge representation of the complex medical knowledge and the Iow efficiency of inference, to seek a new method of building practical MDES.

本论文旨在深入剖析传统专家系统对于知识复杂的医疗领域知识表示困难和推理低效的原因，探讨建造实用MDES的新方法。

This method alleviates the highly dependent on domain knowledge experts. The quality and efficiency of the KBS were improved.

使用这种设计方法减小了对领域知识专家的严重依赖，提高了知识系统开发的质量和效率。

Concept lattice theory and rough set theory,two different methods for knowledge representation and knowl- edge discovery,are successfully applied to many fields.

概念格理论和粗糙集理论是两种不同的知识表示与知识发现的工具，都已被成功应用于许多领域。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
