结构的

In the first part, the thesis mainly checks the concept of urban and rural dual structure, manages to give it a philosophic, definition and then lists various conducts of the contradiction. It also analyzes the subjective and objective reasons that cause the Chinese urban and rural contradiction, and dissect the contradiction抯 feature, history, current situation and influence. This part means to explain that China is a prototypic developing country with Chinese characteristic urban and rural dual structure co!~tradiction. The incisive contradiction exists mainly in seriously backward countryside. In the fields of economy, politics, culture etc, it badly affects and restrains our economy and society抯 sustained, rapid and coordinated development manifoldly and omnibearingly.

第一部分从考察城乡二元结构的概念开始，给予城乡二元结构以哲学定义，然后列举了我国城乡矛盾的种种表现，分析了我国城乡矛盾形成的主客观原因，进而剖析了我国城乡矛盾的特征、历史与现状及影响，旨在说明我国是典型的具有中国特色的城乡二元结构矛盾的发展中国家，城乡矛盾极其尖锐，主要表现为农村元严重落后，在经济、政治、文化等方面，多层次全方位地严重影响和制约着我国经济与社会的持续、快速、协调发展。

Quantum chemical CNDO/2 method has been performed to study 20 chloranlines on the electronic structure in order to analyze their toxicities to Photobacterium Phosphoreum. The correlation analysis and the step regression analysis are put in use in this paper.

研究氯苯胺类化合物的电子结构与发光菌毒性的关系，应用CNDO/2量子化学方法计算了20个氯苯胺类化合物的电子结构，探讨了发光菌在5、15、30 min时间内的半抑制浓度的负对数P(5-EC50)、P(15-EC50)、P(30-EC50)与化合物的电子结构的关系。

A careful analysis proves that the main part of former Chao Yu's dramas is a prisonlike world, but, on the verge of the prisonlike world, there is a bright"horizon"which is an ideal world.

细致的文本分析表明曹禺前期戏剧深层结构的主体部分都是闭锁的世界，而在这个闭锁的世界的边缘则存在着充满亮色的&天边外&即理想国，所以，闭锁的世界和理想国分别是曹禺前期戏剧的主体结构和边缘结构。

This thesis holds that all of Chao Yu's dramas should be divided into former period and latter period; the deep structure of former Chao Yu's dramas is the contrast and opposition of an ideal world to a prisonlike world, and the deep structure of latter Chao Yu's dramas is the"clear sky"; the transformation of former Chao Yu's drama to the latter is a transformation of its deep structure.

本文认为曹禺戏剧存在着前期和后期之分；前期曹禺戏剧的深层结构是闭锁的世界与理想国的对照与对立，后期曹禺戏剧的深层结构则是&明朗的天&；从前期戏剧到后期戏剧的转换是深层结构的转换。

The results of research on community structure through the response of microbes in mangrove swamp under PAHs stress revealed that different changes of microbial community structure had occurred in different concentrations of Phe, Pyr, Flu, Bap and M-PAHs.

不同浓度的PAHs对红树林沉积物中的微生物群落结构的影响不同，较高浓度的PAHs对微生物群落结构的影响也较大，同时在高浓度的PAHs胁迫下，微生物群落结构发生改变的响应时间也较短。

ABSTRACT The emerging and development of resultative verb is a traditionnal problem of grammatical research which evoked heated discussions, and now it has not reached unanimity yet In this article, previous reseaches were summed up, and problems about the reseach of resultative verb were analyzied.

&动补结构的产生与发展&是语法研究的传统课题，也是历来讨论最多、争议最激烈而迄今为止尚未有定论的问题，本文全面总结了前贤时哲的研究成果，分析了目前在动补结构的研究中存在的问题，希望通过这个专题研究，对动补结构的产生、发展及相关问题有一个比较切合汉语发展实际的科学结论。

Resumptively, the construction of new structure will change the third stress field to the fifth stress field in surrounding rock, and bring the safety problem of existing structure and the complexity problem of newly-built structure.

概括地讲，新建结构物的施工会使围岩从原来的三次应力场演变到五次应力场，正是这种应力的演变导致了既有结构和新建结构的受力变异，造成既有侧的安全性和新建侧的复杂性问题。

The present research paper looks at the structural changes of different types of social capital in the course of the development of the family enterprises and finds that it is essential for family businesses to grasp the pattern of the evolutionary change of the social capital structure in order to exercise dynamically external and internal management of the social capital, avert retrogressive change of the enterprises and achieve successful landing at different phases of growth.

通过对不同类型的社会资本在家族企业演化中结构变动的研究，发现家族企业欲实现健康发展，成为有前途的大企业就必须把握成长企业的社会资本结构演变规律，通过企业内外的社会资本结构的动态治理，避免企业演化中的退化陷阱，实现在企业成长各个阶段的成功着陆。

In previous studies, only spherulitic structures of PVDF membranes prepared by PVDF/single diluent systems via solid-liquid phase separation were obtained. The PVDF membranes with spherulitic structures always present poor mechanical properties, dense skin layers and wide pore size distribution.

在以往的研究中，PVDF微孔膜大多数选用的是单一稀释剂，通过发生固—液相分离制备的，所得到的膜结构都是球晶状结构，具备这种结构的膜往往存在膜的力学强度差、皮层致密和孔径分布宽等缺点。

To identify cytoskeletal proteins that change conformation or assembly within stressed cells, in situ labeling of sterically shielded cysteines with fluorophores was analyzed by fluorescence imaging, quantitative mass spectrometry, and sequential two-dye labeling.

从蛋白质的氨基酸序列来预测它的三维结构是计算生物学和计算化学长期面临的挑战。研究人员40多年前就知道蛋白质的结构完全是由其氨基酸序列决定的，但是用序列信息来做结构的预测极为困难。

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。
