A novel non - metallocene supported catalyst, CpTiCl2/MgCl2 - SiO2/ MAO ,was prepared, and the catalysis involved in ethylene homo - polymerization, ethylene - 1 - hexylene and ethylene - styrene copolymerization was investigated.

研究开发了一种新型非茂负载聚烯烃催化剂——CpTiCl2/MgCl2-SiO2/MAO，并考察了该催化剂的乙烯均聚、乙烯和1-己烯共聚及乙烯和苯乙烯共聚性能。

The DES is a small molecule and is not immunogenetic,so it must be synthesized firstly.

国内外研究表明，己烯雌酚可以破坏机体遗传物质，导致基因突变而引发机体肿瘤[1]。

The results showed that at the concentration of 10-8 mol/L,diethylstilbestrol facilitated fetal rat mesencephalic NSCs proliferation and differentiation, and increased neuronal differentiation.

结果显示：己烯雌酚浓度在10-8mol/L时中脑NSCs增殖、分化明显，并能提高神经元的分化率。

Catalysts 1 and 2 were supported on silica particles and the effects of different supporting strategies on trimerization selectivity, 1-hexene incorporation efficiency and copolymerization activity were studied and compared to the homogeneous system.

使用均相或负载化HNC_2H_4SC_(12H_(25)_2·CrCl_3与均相或负载化Et_2ZrCl_2组合成的不同的串联催化体系进行乙烯的化学反应，研究发现，共聚催化剂Et_2ZrCl_2负载化对其活性和1-己烯的插入都有影响。

Then identified and passaged cells and induced to differentiation 5 days later.

SEM showed that the trabecular bone widened, its broken points lessened and its Howship's lacunae shallowed in the groups after treatment.

扫描电镜显示，ALN组及己烯雌酚组治疗后骨小梁宽度增加，断点减少，Howship陷窝变浅。

This paper mainly studies the synthesis of 2-Isopropyl-5-Methyl-2-Hexenal from the optimum reaction conditions of from self aldol condensation of Isovaleraldehy,with NaOH solution as the catalyst of the condensation.

本文以NaOH水溶液为催化剂，探讨了异戊醛Aldol缩合制备可可醛(2异丙基5甲基2己烯醛)的最佳反应条件：反应温度50℃、反应时间9h、催化剂NaOH水溶液的浓度2mol.L1、OH-/异戊醛为1/1，主产物可可醛的产率为92.2%。

Thus, cyclohexene species can desorb quickly from the active sites, avoiding its deep oxidation dehydrogenation.

催化剂的表面上，使催化剂表面形成孤立的活性中心，避免了产物环己烯的深度氧化。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
