掺钦后，电极材料的离子分布形式发生变化，引起材料结构中的化学键产生变化，电极材料充放电过程中的结构相变得到有效抑制，结构变化相应减小，电极材料在高电位下的界面反应活性也减弱，从而减小了由结构变化和界面反应引起的容量损失，改善了电极材料的充放电循环性能。 - the purpose of studying the structure-activity relationship ( sar ) of vitamin e is to study the difference of the molecular geometry, which has different effect on the reaction activity of the molecule and produce different biological activity . semi-empirical ami and pm3 method and ab initio 3-21g methods are applied to optimize the four different geometries of tocopherol in the present work . using the two methods we have obtained some parameters about the biological activity
计算步骤是，先使用hyperchem6构造出各种化合物，用hyperchem自带的分子力学mm+和polak-ribiere优化方法在目标分子的构象空间中寻找能量相对较低的构象，然后用am1半经验方法进一步优化其构型，得到一系列能量值，然后利用hyperchem6.0其中集成的qsar模块，计算化合物的qsar参数，其中包括：疏水性参数(logp)、分子表面积、总体积、折射率、极化率等参数。 - the initial activity of pt / tio2 was higher than that of tio2 because it restrained the recombination of electron and hole with supported pt, however the regenerated ability of the pt / tio2 was lower than that of tio2 . after the regeneration, the activity could come back to some 60 % of the original activity and the reaction activity declined rapidly . the reason might be that after regeneration on the surface of pt / tio2 the incomplete oxidation of h2s to produce s was enhanced
pttio_2催化剂的初活性比单一的tio_2催化剂的初活性高，这是因为担载的贵金属抑制了电子与空穴的复合，但其再生性能比tio_2差，再生后活性只能恢复到初活性的约60，且反应活性迅速降低，这可能由于在再生后的pttio_2表面上，h_2s通过不完全氧化生成s~0的反应增强所致。 - in combination with the characteristics of the molecular structure of carbazole, a possible genetic mechanism of dmcs is proposed : l, x-dmcs may be derived from 1-methylcarbazole by methylation . the methylation at the cyclocarbon positions 3 and 6, with equal chemical reaction activity, would result in equal products; at the same time, competitive methylations would occur between cyclocarbon positions 3, 6 vs 4, 5; different conditions of reactions will result in different preferences of 1, 3-+ 1, 6-dmc or 1, 4-+ 1, 5-dmc
