An approach based on the graph theory is used to study the relationship between bo- iling points of normal alkyl benzene s and its molecular structure,and a quantitative relation is devel- oped which can be used to characterize the structure-property relationship and to prediet the boitingpoints of normal alkyl benzene s.

本文用图论方法探讨了烷基苯的沸点与其分子结构之间的关系，提出一个既能合理表征烷基苯沸点与分子结构关系，又能准确预测沸点的定量关系式。

Second, in this paper we recite and analyse how the painting masters of the different history stage used light and colors from "Prehistorical art" to "Rome art" imitating light and colors,"Middle ages art" creating "Sanctitude light","Revival of learning" representing nature light and colors and then light was used to create the drama light, Impressionistic using the light of science and impairing light instead emphasizing sensibility colors in modern times. Painting lives by the light and colors all along in the painting history.

从史前艺术、希腊罗马艺术的模仿光与色，到中世纪艺术创造神圣之光，再到文艺复兴的再现自然光线与色彩，然后到17世纪的主观处理光线形成&戏剧之光&、印象派的科学用光、现代绘画淡化光线并强调情感色彩，光线和色彩一直贯穿在历史的绘画长河里。

In this paper, finite element software ANSYS is used to simulate the thermal conductivity and pressureless infiltration technique is used to produce aluminum infiltrated silicon carbide composite with high volume fraction of SiC. The influence of interfacial thickness and temperature on thermal conductivity and CTE have been investigated and analysed.

本文采用有限元软件ANSYS对铝渗碳化硅复合材料的有效热导率进行了数值模拟，用无压浸渗法制备了高体积分数的铝渗碳化硅复合材料，研究了界面层厚度和温度等对铝渗碳化硅复合材料的热导率和热膨胀系数的影响，并进行了分析。

Methods Purified 5-LO fragment was injected into male pronucli and the firtilized eggs were transplanted into pseudopregnant mice. PCR and Southern blot were used to detect the genotype of DNA separated from the newborn mouse tail tissues. RT-PCR and Western blot analysis were used to detect the gene transcription and expression. Results PCR and Southern blot results showed that 7 of 25 mice were transgenic mice.

通过显微注射的方法，将5-脂氧化酶基因片段(6.8 kb)导入BDF1受精卵雄原核并移植到同期受孕的假孕母鼠输卵管中，对产出仔鼠的鼠尾组织DNA进行PCR、Southern blot检测，对9、20、24号转基因小鼠分别提取腹腔细胞、骨髓细胞及脾、肾组织总RNA和蛋白，并采用RT-PCR、Western blot方法进行转录水平检测和蛋白表达检测。

Methods: A brain concussion was produced in rats using a simple pendulum device model. One control (n=12) and six experimental groups were used(n=12 in each group). The cerebral concussion groups were assigned to sacrifice times ranging from 1 day to 24days after injury.A Morris Water Maze memory paradigm was used to assess learning and memory function. Pycnosis degeneration or necrosis neurons in the locus cerebral cortex, dorsal hippocampus, dentate fornix and brainstem reticular formation were observed and counted after brain concussion. Cholinergic neurons in the basal forebrain and brainstem reticular formation were identified and quantitated using choline acetyltransferase.
