The selection of geological prospecting in different stages(initial-prospecting, detailed-prospecting)(2)the selection of geological prospecting in the deep-laid and shallow-laid of tunnel project (3)the selection of geological prospecting of tunnel projecting in different geological conditions Finally, the author summed up main problems needing to be solved in tunnel engineering geological prospecting as follow:(1)differentiate stratum and find out the depth and thickness of different stratums in the tunnel section (2)find out geological structure and existence situation of fault, broken zone and weak plane (3)find out weathering level of bed rock to classify surrounding rock combining speed materials (4)differentiate stratum structure of the entrance of tunnel to judge the stability of it (5)find out existence situation and performance of ground water (6)situations of other harmful geological phenomenon In view of above problems and classification of surrounding rock, the author showed principles of rational choosing of methods in geological prospecting and counted disperse range of physical character parameter value in different petrosal character, getting achievements as follow:(1)summarization of effect, merits and demerits of different geological prospecting methods in the tunnel geological investigation (2)method selection and arrangement principle of tunnel engineering geological prospecting in different geological conditions and prospecting stages (3)According to previous experience and cases, the author concluded the物性parameters most in use ,and showed the basis of selecting geological prospecting methods in different geological conditions.

论文中用几个应用实例来说明：(1)不同勘察阶段物探工作的选用；(2)深埋、浅埋隧道工程物探工作的选用；(3)不同地质条件隧道工程物探工作的选用。最后总结归纳出隧道工程物探所需要解决的问题主要有：(1)划分地层，查明隧道通过剖面的各地层深度与厚度。(2)查明地质构造，隧道轴线段有无断层、破碎带、软弱层面等。(3)查明基岩风化程度，从而结合速度资料进行围岩分级。(4)划分洞口地层结构，判断洞口稳定性。(5)查明地下水赋存情况及其活动动态。(6)其他不良地质现象存在情况。针对上述需要查明的地质问题与计算围岩分级情况，论文提出合理选用物探方法的原则，并统计了物性参数值在不同岩性中的分布范围。得出以下研究成果：(1)总结出各物探方法在隧道地质调查中的作用和优缺点。(2)得出不同地质条件下和不同勘察阶段，隧道工程物探方法选择和布置的原则。(3)根据以往工作经验和事例，对常用的物性参数进行了归纳总结，同时介绍了不同地质条件下物探方法选择的依据。

The secondary structure was investigated by Circular Dichroism .

利用圆二色性技术研究了嵌段共聚物在溶液中的二级结构。

The traditional standpoint thinks the Caste System must be abolished completely a period of time in future because it is the draff of traditional culture.In the conclusion part, this viewpoint is rejected. Because the Caste System is a kind of social construction and values system, it is impossible to abolish the Caste System.

传统观点认为，种姓制度因其落后性在未来一段时间内会被作为传统文化中的糟粕而全面废除，在结论部分，文章批驳了这种论断，认为种姓制度是一种社会组织结构和价值体系，从价值观角度讲，种姓制度是不可能被消灭的。

In this lesson, the problem of the shoring form and the support parameters of shallow underground cavity belonging to strong effloresce band, is studied by force method calculation and numerical value analyzing, and so on.

在本课题中，通过力法计算、数值模拟等方面对浅埋强风化段地下洞室支护问题展开研究，并对煤矿井巷工程中的U型钢可缩性支架、型钢混凝土组合结构的设计计算方法进行一定的探讨，为现场工程设计和施工提供科学依据和技术参考。

The fused insecticidal protein may delay the process of insects?developing resistance. After investigation of the secondary structure and action mode of Bt insecticidal protein and Cowpea trypsin proteinase inhibitor, as well as the action mechanism of insect enterokinase, we devised the fusion gene on the base of maintaining their functions respectively. The method follows: CpTI gene is linked to 3?-end of GFM crylA gene by a nucleotide sequence encoding cleavage site of insect enterokinase.

根据Bt杀虫蛋白Cry1A和豇豆胰蛋白酶抑制剂的高级结构、杀虫机理及昆虫体内肠激酶的作用机理，本着尽量不影响二者功能的原则，设计出了构建Cry1A和CpTI融合杀虫基因CryCI的方案，即将CpTI基因的编码序列连接到GFM Cry1A基因编码区3'端，并在其间用一段编码肠激酶切割位点的序列相连。

The micellization is explained by the change in structure and microenvironment of the EO and PO units.

胶团形成的分子机理解释为EO和PO链段在温度影响下的结构和微环境变化。

RESULTS We successfully obtained human caspase-3 gene, the genes and expression vectors of reversed caspase-3 and its fusion protein with part of the translocation domain of Pseudomonas exotoxin A. Compared with the control group, the expression of both genes caused in a similar degree the decrease of living cell numbers and massive occurrence of apoptosis.

结果成功获得了caspase-3基因，构建了重构型caspase-3基因和重构型caspase-3与绿脓杆菌外毒素转膜结构域部分肽段的融合蛋白基因及其表达载体，与对照组相比，在转染后1～4 d内，两种基因的表达均导致HeLa细胞存活数减少，大量细胞发生凋亡，且二者活性相当。
