In all kinds of energetic materials, Nitrogen heterocyclic nitramine has been the focus of research, and its representation are HMX and RDX, both of them are the most important.

在其发展过程中，最重要的就是作为氮杂环硝胺代表的HMX和RDX。

Molecular rearrangement reaction occurs during the foaming and post-treatment forming hexahydric imide ring. The prepared PMI foams have closed cell structure with the cell size ranging from 0.5mm to 0.7mm and have a good thermostability with the characteristic degradation temperature at about 221.5℃.

Objective To investigate the effects of the Chinese drug Zilongjin and hexamethylene bisacetamid on expression of oncogenes(c-ras,c-myc),and tumorsuppressor genes(Rb,p53,p21)of MGc803 cell in cell cycle.

目的 探讨中药紫龙金与环六亚甲基二己酰胺对人胃癌MGc80 3不同周期细胞癌基因c ras、c myc、抑癌基因Rb、p5 3、p2 1以及蛋白激酶PKC a基因表达的影响。方法采用Northernblot印迹法检测基因表达情况。

The 1,3-dipolar cycloaddition reactions of various substituted ynamines with hydrazoic acid were theoretically investigated with the high-accuracy CBS-QB3 method.

采用高精度CBS-QB3方法对一系列取代炔胺与叠氮酸之间的1，3环加成反应进行了理论研究。

Tetrachloroterephthalic acid was prepared by chlorinating terephthalic acid, oleumsolvent and iodine catalyst. Tetrachloroterephthalic acid was acylated by sulphurous oxychloride in the presence of DMF to form tetrachloroterephthaloyl chloride. The acyl chloride product was fluorinated by potassium fluoride and esterified by methanol to synthesize dimethyl tetrafluoroterephthalate. The ester was reduced with potassium borohydride and lithium chloride to give tetrafluoroterephthalyl alcohol. The above product was bromated in the hydrobromic acid to obtain 4-bromomethyl-2,3,5,6-tetrafluoro-benzene methanol. 4-Methyl-2,3,5,-6-tetrafluorobenzene ethanol was obtained by reducing the bromide with magnesium. In the exist of DCC and DMAP, tefluthrin was got by the condensation reaction between 4-methyl-2,3,5,6-tetrafluoro-benzene methanol and-(1RS,3RS)- 3-(2- chloro-3,3,3-trifluoro-1-propenyl)-2,2-dimethyl cycolpropanecar-boxylate acid.

对苯二甲酸与氯气在碘存在下以发烟硫酸为溶剂进行氯化制备四氯对苯二甲酸；再以DMF为催化剂与二氯亚砜反应生成四氯对苯二甲酰氯；以氟化钾为氟化剂，环丁砜为溶剂置换氟化，再与甲醇酯化得到四氟对苯二甲酸甲酯；以KBH4-LiCl为还原剂二甲醚为溶剂反应制得四氟对苯二甲基苄醇；以氯苯为溶剂在溴化氢溶液中溴化得到溴化产物；在乙醇溶液中经镁粉还原得到4-甲基-2，3，5，6-四氟苄醇；甲基苄醇与功夫酸在催化剂二环己基碳二亚胺和4-二甲氨基吡啶作用下缩合得到七氟菊酯，总收率达43.6%。

Female CB6F1 mice (F1 mice in short) which had been hypodermically inoculated with hepatoma cells (H22) were as recipients, and the C57BL/6 mice were as the donors. CB6F1 mice received intraperitoneal chemotherapy with cyclophosphamide. Fresh bone marrow and spleen cells from C57BL/6 mice were as donor cells, which were divided into with or without radiation of 60Co.

实验方法：以皮下接种肝癌细胞（H22）的CB6F1（BABL/C×C57BL/6杂交鼠，简称F1）雌性小鼠为受体鼠，经环磷酰胺腹腔化疗后，取C57BL/6小鼠的新鲜骨髓及脾脏细胞作为供体细胞，供体细胞分为经60Co照射和未经60Co照射。

Objective: To investigate Jiaohao aetherolea influence the immune hypofunction of mouse, which is induce by cyclophosphamide.
