By the best approximation theory, it is first proved that the SISO (single-input single-output) linear Takagi-Sugeno fuzzy systems can approximate an arbitrary polynomial which, according to Weierstrass approximation theorem, can uniformly approximate any continuous functions on the compact domain.

借助于最优逼近理论，证明了线性SISO TS模糊系统可以逼近任意一个多项式，然后以Weierstrass逼近定理为桥梁，证明了该模糊系统可以以任意精度逼近一个任意的连续函数，从而得到了该模糊系统万能逼近性的一个新的充分条件。

In the first half of the 18th century, Russian jurists fused the thoughts of jurisprudence derived from idealist apriorism and classical natural law theory of the European Continent, especially of Germany, and the Slav culture and the Orthodox Eastern Church tradition into initial jurisprudence of Russia.

十八世纪上半叶，俄罗斯法学家从欧洲大陆，主要是德国，汲取了先验唯心主义和古典自然法的法哲学思想，并把这种思想与俄国的斯拉夫文化和东正教传统结合起来，形成了俄罗斯早期法哲学。

Short-range wireless communication technology has attract many people"s interests now. Bluetooth is an international standard for it, but it now has a lot of problems. This paper first analyzed Bluetooth"s basic theory,architechure,solution. To meet this great market this paper put forward a low-cost and easy solution.

短距离无线通信是当前的一项热点技术，已经制订的国际标准是蓝牙，本文首先分析了蓝牙技术的基本原理、系统结构和实现方案，根据蓝牙目前存在的一些问题，本文提出了一种简单实用的短距离无线通信解决方案。

First the math theory of machining simulation is studied, and the set structure of NC machining simulation system whose components, including time, input, output and so on, are defined. Hereby we set up the hierarchy structure, the logical structure, the static model and the dynamic model of simulation system. The construction method of sweep entity of cutter and rotation parts is researched, and their differential geometry invariants are calculated. NC code is unscrambled, and the recursion division arithmetic of time segment is put forward, which is the driven data of the movement or rotation parts. The CLDATA should be interference-free. To examine if there is interference between cutter flank and the work piece, an arithmetic that discussed the existence of intersecting curve between them is put forward. To examine if there is interference between two turrets, an arithmetic that discussed the existence of intersection set between two polygons is put forward.

首先研究加工过程仿真的数学基础，然后定义数控加工仿真系统的集合结构及时间集、输入集、输出集等概念，建立加工仿真的层次结构和逻辑结构，阐述双刀车削仿真系统的静态模型和动态模型建立方法，分析刀具扫描体和旋转部件扫描体的建立方法及其微分几何性质；研究NC代码解读技术和双刀加工时间段递归子分划技术，为驱动各仿真单元作数据准备；通过讨论后刀面和工件表面交线的存在性判断刀具后刀面与工件间是否干涉，通过求多边形的交集判断刀架与刀架是否干涉。

It discusses Arnheim's theory in two aspects: First, starting from the Gestalt psychology, it puts film into the category of traditional art and, by means of its comparison with other forms of art, such as opera and painting, concludes that film is art only because it fails to perfectly represent the reality.

到了 20世纪二三十年代，电影在创作实践上进入了它的第一个辉煌阶段———默片的全盛时期。由于创作实践的巨大进步，电影当然不能安于卡努杜所谓的"没有理论的艺术"①的现状，在理论上确认电影作为艺术的身分是势所必然。1932年，德国心理学专业的大学毕业生爱因汉姆撰写了《电影》一文。

At the beginning of the reform and opening-up, aiming at the average assignation bringing the huge damage to efficiency, Deng Xiaoping put forward to a basic theory that let a small part of people enrich first.

改革开放初期，邓小平针对平均分配对效率造成的巨大损害，提出了"让一部分人先富起来"的论断。

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。

This article is composed of three parts: The first is the establish grounds of assistor by omission. In my view, firstly, the assistor by omission belongs to its own theory in China. We should not deny its complicity character, just because there are the difficulties in distinction between assistor by omission and criminal omission.

本文共分为三部分：一、不作为帮助犯的成立依据笔者认为，在中国，不作为帮助犯有其应有的理论归属，不能因为在不作为犯罪中存在区别正犯与共犯的困难，就否定其共犯的性质，将其另划为一个独立的犯罪形态。

Myth and art are interknit from their birth. The first, myth and art all are fictions. The second, myth has double structures of conception and sensibility, theory and art. The third, be related to the characters of mythical thought, myth had unified intuitive images and feelings, but feelings of myth is different from that of art. The forth, feelings of art have a character of associability.

神话和艺术从生成始就是有着密切的联系的：首先，神话和艺术一样都是一种虚构；其次，神话具有概念和感性、理论和艺术的双重结构；再次，与神话思维的特征相关，神话具有直感性与情感的统一性，但是神话中的情感不同与艺术中的情感；第四，神话情感有交感性的特点。

In chapter four,at first,we investigate classification theory of the positive homogeneous p-Laplacian equation ,the main method is Prufer's transformation,and then we discuss the nontrivial solution for associated nonhomogeneous equation by making use of Leray-Schauder degree.

接着研究了非齐次方程的可解性。在第四章中，我们首先是建立了正齐次p-Laplacian 方程的分类理论，主要利用Prufer 变换。再应用Leray-Schauder 度理论证明非齐次方程的可解性。

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。
