概念上的

With the new concept,the problem of variable structure control of 2D discrete system is transferred to the problem of seeking a sliding model with good sporting character and attractability. The concrete design schemes of the imitative sliding model and variable structure controller are also put forward. And the concrete expression of the time T in ε-neighborhood of reaching switch manifold is obtained. The difficulty of applying the existing methods to MIMO systems is overcome.

在新概念之下，将2D离散系统的变结构控制问题转化为寻找一个既具有良好的运动品质又具有吸引性的滑动模问题，给出了滑动模及变结构控制器的设计方案，并且获得了达到切换流形的ε领域的时间T的具体表达式，克服了已有方法难以应用到多输入—多输出系统上的困难。

So, the main tasks of bill broker" s system construction in our country are: sound and perfect relevant law, regulation, management organization and function about bill broker system, make the concept of the bill broker clear, confirm its status legally is especially important at present, and pay attention to integrating with the world; Strengthen entering system management and independent management of the security broker, perfect the structure and function of self-organized system by oneself; To the future transform trend of our broker mode of securities market mode from traditional type to "network manager","bill broker manager" and "fund manager", We should pay attention to setting up perfect management mechanism of risk and inside management system of bill broker"s system even more, enforce the financial rule, expand the scope of business, setting up systematic, perfect risk preventive and controlling system; To be strict in registration system of bill broker representative and qualification, guarantee professional quality and good quality of our bill broker representative team, pay attention to studying and using the rational incentive mechanism, strengthen the cultivation and development of bill broker representative team.

因此，我国证券经纪人制度建设的主要任务是：健全并完善有关证券经纪人制度的法律、法规、管理机构及其职能，明确我国证券经纪人的概念，确定其在西安理工大学硕士学位论文法律上的地位，并注重和国际接轨；加强证券经纪商的准入制度管理和行业自律制度建设，完善自律组织的结构和功能：针对未来我国证券市场经纪模式由传统型向"网络经纪"、"证券经纪人经纪"和"基金经纪"转化的趋势，我们更应该注重建立完善、科学的证券经纪人制度的风险管理机制和内部管理制度，严格财务制度，扩大业务范围，建立系统、完善的风险预防和控制体系；严格证券经纪代表的注册制度和资格审查，保证我国证券经纪代表队伍的专业素质和良好品质，重视研究和应用合理的激励机制，加强证券经纪代表队伍的培育和发展。

The macro-contextual analysis of this genre of discourse indicates that the macro cultural context of Chinese GPC results from the composition forces of traditional Confucianism, i.e.,"ren" and"li" theory, as well as the modern civilization and the culture by political system in socialist China.

研究表明，宏观的文化语境(指以"仁"、"礼"要义为主的中国儒家传统文化和社会主义制度下的现代文明与政治文化形成的"合力")形成我国政府新闻发布会话语建构与理解的"国家认同"，并从意识形态得以体现，其中表现在言语层面上的最典型的是"国"即"家"的概念隐喻。

Connectivism and Connective Knowledge is a twelve week course that will explore the concepts of connectivism and connective knowledge and explore their application as a framework for theories of teaching and learning. It will outline a connectivist understanding of educational systems of the future. George Siemens and Stephen Downes – the two leading figures on connectivism and connective knowledge - will co-facilitate this innovative and timely course.

"连接主义和连接的知识"，是一个12周的课程我们开始探讨连接主义的概念和知识之间的连接，继而探究其在教和学上的应用，也同时勾画出了一幅连接主义者视角下的未来教育图景， George Siemens and Stephen Downes 两位连接主义知识下的领军人物将会一起引导这个极具创新意识同时也很及时的课程。

Defective economic manis defined as fuzzy-headed rational man and he pursuefor benefit not only economic benefit but also non-economic benefit.Then he purchases not onlygoods in physical form but also goods in non-physical form such as national defence through taxpayment.

为了将许多传统意义上的非经济因素纳入经济学的研究范畴，本文提出了非物化商品的概念，从而扩大了商品的范围，使得我们对"有缺陷的经济人"追求的经济利益和非经济利益能够综合起来一起考虑，完成了作为"有缺陷的经济人"的消费者的行为模式分析。

We generalize the concept of the set of variability defined in the unit diskby K.Strebel to general Riemann surfaces and prove that the set of variablity withrespect to the modulo homotopic class of a quasiconformal mapping between twoRiemann surfaces is a compact and connected subset.Consequently the num-ber of the extremal mappings in the modulo homotopic class of a quasiconformalmapping between two general Riemann surfaces is either one or infinity.

Strebel的定义在单位圆上的可变性集合的概念推广到一般Riemann曲面上去，并且证明了Riemann曲面之间的拟共形映射的模边同伦类所确定的可变性集合是一个连通的紧子集，从而得出一般Riemann曲面之间拟共形映射的模边同伦类中的极值映射要么唯一，要么有无穷多个。

Nevertheless,due to the respect of the traditions of the West for the lin guistic norms and logical determinativeness,the word"being"has been raised to the height of the th ing -in -itself of the world and real substance and thereupon,it has got the dual meanings of"be"as a link verb and"exist"as a transitive verb,thus embodying the unity of the logos spirit and the nous spirit in the w.

西方哲学自古希腊以来的一个核心概念Being的原始含义固然是一个逻辑系词"是"，但由西方传统对语言规范及其逻辑确定性的尊重使这个词上升到了世界本体和真正实体的崇高地位，从而使它带上了系词"是"和动词"存在"的双重含义，体现了西方文化中逻各斯精神和努斯精神的统一，这是中国古代以农业为本的文化传统所难以理解的文化现象和语言现象。

No special modes of coordination set the activities of hunting or gathering,or the procedures of distribution, apart from the rest of the social life ,so that there is noting in Kalahari life for which there is needed a special vocabulary or conceptual apparatus called "economics."

除非在社会生活的其他方面，没有什么专门的协调办法来安排打猎或者采集活动，及其物品的分配办法。因此，在科拉哈里人的生活之中，没有任何事情需要使用一个概念上称为&经济&的专用词汇。

This method has improved the reusability of the code in GA on the concept level.

这种方法改变了在传统的遗传算法中各个函数之间只有参数的传递，而没有代码的继承性的状况，从概念上提高了软件的可重用性。
