两极的

This paper is based on "Trilemma" which is induced from MF model. In order to overcome MF models inherent defects, this paper constructs a static model headed by government on choice of optimum exchange rate regime. Through the analysis of the model we can see that the choice of exchange rate regime is a dynamic process should be decided in real situation. No single exchange rate regime is right for all countries or at all time. Under certain condition intermediate regime may be the optimum one, but the possibility will decrease with the increase of international capital flow.

本文从蒙代尔——弗莱明模型精炼出的"三元悖论"出发，为了克服其内在的缺陷，构建了一个政府主导的静态最优汇率制度选择模型，模型分析表明：汇率制度选择是一个动态的相机决策过程，没有哪一种汇率制度对所有国家或某一国的所有时期都适合；在一定条件下，中间汇率制度可能是最优汇率制度，但是其可选择的区间随着资本流动程度的加大而缩小，最终最优汇率制度将内生的向两极分化。

According to the distribution of the positive charges inthe surface of the cage, it can be expected that two -OH groups finally adding at two sites which arewithin one hexacyclic ring and in different sides of equator, which is accord with the conclusion resultedfrom thermodynamics

通过寻找并分析过度态的结构，发现酸化阳离子中处于赤道带6-6类碳原子上的羟基和两极区域5-5类碳原子上的羟基都有朝邻近赤道带碳原子上迁移的可能，结合碳笼上正电荷的分布特征，预计亲核水解作用将发生在赤道异侧六员环的对位，说明考虑动力学因素，最终获得1，4-加成富勒醇的可能性最大，该结论与热力学的结果一致。

A series of consequent negative influences are mainly as follows. In terms of the loss of natural ecology, the traditional technical innovation cajoles people into inappropriate consumption, causes the malformed development of techniques, results in the ecological loss of technical rationality and functions as an amplifier to technical dissimilation. In terms of ecological loss of society, due to ecological loss of themselves, traditional activities of technical innovation will produce bad effect on people's value views, on much loss of intellectuals in undeveloped countries,on social economy,on political and economic orders in the world and on polarization between the rich and the poor.

由此而带来一系列的负面影响，这集中表现在：在自然生态缺失方面，传统技术创新诱导了人们的不正当消费、导致了技术的畸形发展、造成了技术理性的生态缺失以及对技术异化起到了放大器的作用；在社会生态缺失方面，由于自身的生态缺失，传统技术创新活动对人类的价值观念、对落后国家的人才流失、对社会经济、对全球政治经济秩序以及对贫富两极分化亦会产生一些不利的影响。

The results showed that: at metaphase I, the homoeologous chromosome pairing among different F1 hybrids ranged from 2.0 to 11.4 bi-valents formed by homoeologous chromosomes per pollen mother cell, and very few multivalents, and even very few bivalents were formed by two chromosomes within one genome rather than homoeologous chromosomes in some PMCs; at anaphase I, all biva-lents were disjoined and most univalents were divided.

结果表明在中期I阶段，这些杂种一代的近缘染色体联会变化很大，每个花粉母细胞中二价体形成的数目从平均2个到11.4个不等，甚至在某些花粉母细胞中，还发现极少的多价体和非部分同源染色体所形成的单基因组内二价体；在后期I时，所有的二价体分离，同时多数单价体也分离，分离的二价体和分离的单价体都移向两极，从而形成两组染色体；因为这时完整花粉母细胞中分离的二价体在两组染色体中总是对应出现，从而根据半二价体上染色体重组的位置可以分析在二价体的四分体时期发生在非姊妹染色体之间的多种染色体交换类型，如单交换、三线双交换、四线双交换、四线三交换和四线多交换。

Migrant workers should be combined with the characteristics of the group, due to lower payment rate and strengthen the social security system in urban and rural areas of convergence, the classification of the establishment of migrant workers the minimum livelihood guarantee system for migrant workers groups and the characteristics of the stratified social security system.

所以，到校伊始，同学们首先就必须端正自己的学习态度，树立远大的理想和抱负。有近15%的同学在860元～1350元之间，这就比较自由了。。有了良好的开端就会有美好的希望。4。消费差距拉大，出现两极分化我们曾经搞过一次关于大学生在消费调查，其结果有近16%的同学在350元以下在比较困难的生活线上坚持学业；。高职新生在肯定自己、相信自己的同时，也必须意识到自己的弱点和不足。

The film is Petchai Wongkamlau directed the gangster movies, read many kung-fu, gunfights quite wonderful stories, and we can see in the film director for severe rich-poor polarization of Thai society: the bodyguards, politicians, millionaire, police, journalists, underworld killer of school teachers and the slums and children, the mental patient, disabled, hobo etc, these different characters in the film are living condition, although cannot reach but also can see the director Petchai heart Wongkamlau in the middle of the skill, caused the attention of many fans at home and abroad, and anyone predicted that he is Asia next Jackie chan.

本片是Petchai Wongkamlau自编自导自演的黑帮电影，影片看点很多，武打、枪战相当精彩，故事情节扣人心弦，在影片中我们可以看出导演对贫富两极分化严重的泰国社会的关注：政客、富翁、保镖、警察、记者、黑社会杀手以及贫民窟里学校中的老师和孩子、精神病人、残疾人、无业游民等等，这些不同身份的人物的生存状态在影片中都有所表现，虽然不能面面俱到但也能看出导演的良苦用心Petchai Wongkamlau在本片中层现的身手相当出色，引起了海内外很多影迷的注意，并有人预言他是亚洲下一个成龙。

Wrights class theory has great significance in practice to our understanding of the new changes in class relations of contemporary capitalism and the development of Marxism according to the new changes: Firstly, Wright'theory of the new changes in contemporary capitalist class relations will enable our understanding of this class structure to be founded on more complete analytical data, and make us have a more accurate knowledge and understanding about the non-applicability of Marx's prediction in his class theory of polarized class relations in capitalism.

赖特的阶级理论对于我们认识关于当代资本主义社会阶级关系新变化并且根据这种新变化来发展马克思主义具有很大的现实意义：首先，赖特的当代资本主义社会阶级关系新变化的理论，使我们对当代资本主义的阶级结构的认识能够建立在比较完整的数据分析基础之上，也使我们对马克思所预言的资本主义阶级关系两极分化的阶级理论在当代的不适用性有了更加准确的认识和了解。

in the long-term of the education teaching process, the head quarter appear a student study effect of two pole divide phenomenon, divide "learn excellent living" and"learn to trap to living" is two greatest categories, particularly learn to trap living of the problem be more and more valued by the large teacher.aim at this phenomenon, my school specialized establish a topic research group, the theories background and material background that is from the topic 2 carry on analysis study, try hard for to make track for a root to trace to origins, find out some more practical viable way, scoop out learn to trap living of intelligence potential, exaltation study interest, contract a student study the margin of effect.
