Methods①The animal model of braincontusion caused by free drop hammer was established.②The injuredtissue of rat brain were stained by TUNEL for apoptosis,immunohistochemistry for Caspase-3 and Feulgen"s for DNA. Image analysistechnique and the statistical method were employed to explorate thetemporal changes of injury time.③The DNA was extracted from ratcontusive tissue of brain and assayed by gel electrophoresis toinvestigate the relationship between the DNA fragmentation and injurytime.④One handred and seventeen cases of death from traumatic braininjury were retrospective researched to investigate the characteristicof TBI in forensic medicine.⑤The contusive tissue of human brain werestained by TUNEL, Caspase-3 immunohistochemistry and Feulgen"s methodsin the same way to analyze and disclose the linear relationship betweentemporal changes with injury time.

方法①建立大鼠自由落体打击脑损伤模型；②对不同损伤时间组的大鼠脑挫伤组织进行TUNEL、Caspase-3免疫组化、Feulgen's DNA染色，结合图像分析技术和统计学分析，探讨脑挫伤后神经细胞凋亡、DNA片段化和含量的时序性变化；③提取大鼠脑挫伤组织DNA进行琼脂糖凝胶电泳分析，观察DNA片段化随损伤时间的变化特点；④对117例颅脑损伤致死案例进行回顾性分析，探讨其法医学特点；⑤选择不同损伤时间的人脑挫伤组织同样进行TUNEL、Caspase-3免疫组化、Feulgen's DNA染色和分析，观察上述指标与损伤时间的关系。

A novel planar chiral diferrocenylimine-diols 6 was synthesized by the condensation of R, S(subscript p-1-(2-diphenyl hydroxyl methyl) ferrocenylethylamine [R, S(subscript p-4] with phthaldehyde in anhydrous ethanol, and was crystallographically characterized.

通过R，S(下标 p-1-（2-二苯基羟甲基）二茂铁乙胺[R，S(下标 p-4]和对苯二甲醛在无水乙醇中的缩合反应合成了一种新型平面手性双二茂铁亚胺二醇化合物6，并经X-射线衍射分析它的晶体结构。

On decadal timescale, the highest and second highest values of Ca〓 and Mg〓 occurred in 550's and 380's respectively, which are related to cold and arid climatic conditions.

在十年尺度上，Ca和Mg离子的最高值和次高值分别出现于550's和380's，它们均与冷干气候相联系。

S —008 deflocculant and S —009 paint remover, are just to aim to treat the un-useful / wasting paint inside the painting-room, it can decompose the paint and let it loss glutinosity to float up with all shaped flocculation, and can make water clear but without the wasted paint deposition, without to adhibit to the equipment surface.

S —008悬浮剂与 S —009去漆剂是针对喷房内废油漆之处理，使油漆分解，失去粘性，全部成团上浮使水质变清，废漆不沉淀，不粘于设备表面，废水可达国家三级排放标准，大大延长喷涂设备使用寿命。

In chapter four, the preperation of ytterbium diiodide was examined. The reductive cleavage of Se-Se bond and S-S bond induced by ytterbium diiodide was investigated. The reaction of diselenides and disulfides with allylic bromide promoted by ytterbium diiodide was also examined. The intermolecular Barbier-type reaction induced by ytterbium diiodide was studied. In the last section of this chapter, the intermolecular reductive coupling of nitriles with azides induced by samarium diiodide was investigated.

第四章，研究了二碘化镱的制备方法，以及二碘化镱作为一种优良的单电子转移试剂在有机合成中的应用：二硒醚的Se--Se键和二硫醚S-S键的还原断裂，及其在合成烯丙基硒醚，硒代酯和烯丙基硫醚，硫代酯中的应用，实验结果表明二碘化镱也能促进分子间的Barbier反应，而文献认为二碘化镱不能促进分子间的Barbier反应；最后研究了二碘化钐促进的叠氮化合物与腈的交叉还原偶联反应，一步高收率地制备脒的方法。

With stress calculation analysis and experimental verification, it could be concluded that when b/s is small (.2), the disalignment could be restored by polishing. When grater, by repair welding with width no more than 100mm Meanwhile, when controlling stress level is .5, allowable value of disalignment and angle deformation could be .7s.

通过应力计算分析和实验验证可以得出：当b/s较小(b/s.2)时，错边可以用磨削方法进行修复；当b/s较大时，可用堆焊方法进行修复，且堆焊宽度H不超过100mm同时，在控制应力水平不超过1.5时，错边量和角变形量的和可以允许在不超过0.7s的范围内。
