有变化的

Precise knowledge of the temporal and spatial structure of the tropopause is necessary in order to evaluate the exchange of mass, water, and chemical constitutes between the troposphere and the stratosphere.

为了评估对流层和平流层之间的质量、水汽和化学成份的交换在全球气候和环境变化中的重要作用，研究对流层顶的时空分布结构及这种变化对于该区域臭氧和其它微量成份变化的作用，以及对大气臭氧总量的影响是一个有重要意义的问题。

Dewey finds in rational technologies the element that has contributed most to the altered circumstances associated with the possibility of a shift from the presupposition of scarcity to that of abundance and from that of individulaity to corporateness.

杜威发现，在理性科技中，大部分分配到已变环境中的元素与变化的可能性相关，这些变化有从假设的不足到充裕，从个体到集合。很多专业词语可能翻译的不准确，但是我觉得句子结构就是这样的，红色的是中心句杜威发现元素和变化的可能性相关。

Possible reasons for this failure may be that obesity is so physiologically complex that no single gene or even handful of genes is likely to have a dispositive role, that examining gene gene interactions is difficult without large numbers of subjects, and that variations among current candidate genes are not the most important contributors to human adiposity.

其他有明显量的变化的基因很难证明，可能的原因就是肥胖是一个复杂的生理变化过程，单个基因或一部分基因会能起到真正的作用，没有大规模人群实验检测基因相互作用还很困难，而且当前的候选基因变化并不是人类肥胖的主要原因。

The results showed that rice straw growth and fascicular alteration interacted when water was deficient. It not only affected the transportation of nutritious substance from rhizine and leaf to kernel, but also led to the decrease of agronomic characters and yield. 4 ecotypes of rice vascular bund...

结果表明：水分不足对稻秆及秆中维管束的影响是相互的：稻秆的发育情况影响了维管束变化，同时维管束的变化影响了稻秆的发育，最终影响营养物质从根部、叶部向籽粒运输，从而使结粒数、稔实率、千粒重、产量下降。4种生态型水稻维管束系统与一次及高次枝梗数目、结粒数、千粒重等有类似的相关性，而且水分不足时反应出相同的结果，说明土壤水分对维管束系统的分化有很大的影响，水分不足将使维管束面积变小，维管束比增大，从而使产量变小。

Results showed that contents of IAA and ABA in peduncle, bourse and the tissues around abscission zone among several cultivars were very different, but their trend of change was similar, IAA content decreased and ABA content increased toward harvest time for all the cultivars. Ethylene evolution in fruit of the cultivars with higher preharvest drop was evidently higher than the cultivars with less preharvest drop. Cellulase activity in the tissues around abscission zone of the cultixars with higher prehanest drop rapidly increased toward harvest time.

结果表明：不同品种果柄、果台和离层部位组织中IAA和ABA含量变化有差异，但它们变化的总趋势相似，都是随着果实成熟IAA含量下降，而ABA含量上升；不同品种的成熟果实中乙烯发生量有很大差异，以落果多的品种显著大于落果少的品种；采前落果重的品种离层部位组织中细胞壁分解酶的活性在果实成熟期急剧增加。

Thunderstorms mainly occur in summer with obvious diurnal variation. Analyses indicate that the general trend of Shandong thunderstorms has wavily reduced during the last 40 years .The interannual and decadal variabilities of thunderstorms are obvious in Shandong Province.

结果表明：山东省年雷暴日数的空间分布呈现出泰沂山区多、半岛沿海和山东西部平原较少的特点；雷暴主要发生在夏季，有明显的日变化；在过去40 a中，山东雷暴日数具有较强的年际、年代际变化，呈明显的波动下降的特点，并有一定的阶段性。

Thethesis compares the characters of ecosystem service in different district, main drainage basinand different segment in it, confirms the rules that the ecosystem service value is higher insouthern area than northern area and different characters along river and ridge. The ecosystemservice value is decreased regularly with the increasing of population density and elevationby compared analysis. The results of the ecosystem service values in 1981 and 2001 shows arule that ecosystem service value is steady for whole researched region and fluctuate in localarea in LRGR.

本文对比了各行政区、主要流域以及流域内部不同区段的生态系统服务功能特点，确定纵向岭谷区生态系统服务功能价值存在着南高北低的空间分布规律，且在河流、山脊处有着不同的变化特点；通过分析不同人口密度和海拔梯度下生态系统服务功能的价值，得出生态系统服务功能价值有随人口密度和海拔升高而下降的规律；通过对比81年与2001年生态系统服务功能价值的变化，阐述了纵向岭谷区生态系统服务功能价值总体稳定、局部变化的规律。

The first chapter describes the phonetic system, and arranges the words in the same syllable, at the same time introduces some characteristic vocabularies(mostly the single-syllable vocabularies)as far as possible, then analizes the phonetic changes in initials, finials and tones; the second chapter divides the often-used words into three parts by investigations, then analizes the cause of the change; the third chapter makes a complement to the grammar which other researchers haven"t spoken of; in the end, the paper talks about the author" elementary idea on the relationship between dialect"s research and Putonghua"s use. With the development of our society, this question will be put on more eyes.

论文首先介绍徐州市区方言的语音部分，描写了音系及其特点，在同音字汇部分整理并排列了徐州方言的同音字，同时也尽量搜罗有特色的方言词列入相应的音节内，然后从声母、韵母、声调三个方面分析徐州市区方言的语音变化；其次是词汇部分，通过调查对徐州市区方言常用词的变化情况作了区分，并分析其变化原因；接着在语法部分对前人尚未涉及的语法现象作了补充；最后结合方言研究与普通话使用的关系谈了自己初步的认识，随着社会的不断发展，这个问题将日益引起人们的重视。

Wheares under buffer pH5.2, there is no strong static electricity and instead being a longer wavelength movement; SDS\'s participation just restricts the relative movement of heme\'s ethylene; a new fluorescent peak forms and the reduction of enzymatic activity is due to the packing of micella\'s formation.

强变性的阴离子表活剂SDS与带净正电荷和弱负电荷的SBP(处于pH2.6和4.2缓冲液中)有强烈的静电力作用，酶活力丧失，二级结构变化，荧光强度增加，特征Soret发生蓝移，卟啉环的π-π*共轭的分裂能增大；而当SBP带净负电荷(pH5.2)时，没有静电吸引力，Soret带发生红移；SDS的引入只是限制了血红素上乙烯取代基的运动，使其与卟啉环共轭：极性环境的变化导致产生新的荧光峰；酶活力因胶团包裹作用而有下降。

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。
