The results suggest that the tertiary amine reactivators are complementary to the whole active gorge and some AChE inhibitors, such as Hup A and THA, are only complementary to part of the active gorge.

AChE活性中心空腔与叔胺型重活化剂在空间上有很好的互补关系，石杉碱甲和塔克林则只与空腔的一部分互补。

Chemical mimic of the Fe-only hydrogenase active site is mainly discussed in this thesis.

The recent growing up of chemistry of hydrogenases, especially the Fe-only hydrogenase have renewed interest in classical organometallic diiron dithiolate complexes.

近几年发展起来的氢化酶化学，尤其是唯铁氢化酶活性中心的化学模拟研究，把铁硫簇化学的研究推向了又一高潮。

Since the first crystal structure of the Fe-only hydrogenase was published in 1998, intensive efforts have been spent on the structural and functional models of Fe-only hydrogenase due to its great capability of catalyzing the reduction of protons to molecular hydrogen at extraordinarily high rates.

自从1998年唯铁氢化酶的第一个晶体结构发表以来，由于它可高效地催化质子还原成氢气，其活性中心的结构和功能模拟受到了广泛关注。

In nature, imidazole participates in many important biochemical reactions, acting as the functional group in enzymes active centers.

在自然界中，咪唑作为酶的活性中心功能基团，参与了不少重要的生物化学反应，对生命活动起着十分重要的作用。

The higher selectivity to isopentenes, however, was regarded as a consequence of both insufficient active sites for further hydrogenation of isopentenes to isopentane and lower electronic interaction between Pd and the alumina surface.

而较高的选择性则可归因於没有足够的钯活性中心可供异戊烯进一步氢化生成异戊烷以及钯金属和氧化铝间较低的电子效应所致。

In the polymerization system,there are two kinds of active centers having higher catalytic activity for isoprene polymerization.

事实表明，该聚合体系中存在着两种过渡金属活性中心，它们按各自的机理进行异戊二烯的聚合。

Simulation of Loop domain near active site was carried out with the PROLOOP programm. The initial model was energy-minimized by the 500 steps of steepest descents method and 500 steps of conjugate gradients . The Vanderwal contacts were eliminated, and the energy of the static electric interation and hydrogen binding were adjusted

优化工作用PROLOOP程序，将活性中心附近LOOP前后的有关残基构象进行最佳拟合，并采用GROMOS软件包中的能量优化程序，作500步最陡速降法及500步共扼梯度法进行优化，彻底消除范德华半径重叠，并进行原子间静电和氢键作用的优化调整，最终得到UK-B链最优结构。

By calculating the sub-cluster parameters and the total antioxidant capability parameter of some kinds of fresh vegetable with diet therapy function, we found that there is clear linear correlation between distribution parameters of biopolymer active center elements (1-x)1/3ln(r1r2/k)、(1-x)1/3ln(k2r1/r2) and antioxidant capability parameter ln[F(1-x)3], and which show monotone decreasing and monotone increasing respectively.

同时对更大范围内的9大类蔬菜和5大类水果的生物高分子活性中心元素分布及其维生素C及维生素E含量进行了考察，结果发现群子统计参数(1-x)1/3ln(r1r2/k)、(1-x)1/3ln(k2r1/r2)与维生素C、E含量参数lnVc(1-x)3、lnVe(1-x)3均分别呈单减和单增的线性关系。

Conjugated enzyme :An enzyme that contains nonprotein component in addition to the amino acids.

Lugalbanda was a god and shepherd king of Uruk where he was worshipped for over a thousand years.

Lugalbanda 是神和被崇拜了一千年多 Uruk古埃及喜克索王朝国王。

I am coming just now,' and went on perfuming himself with Hunut, then he came and sat.

我来只是现在，'歼灭战perfuming自己与胡努特，那麼，他来到和SAT 。
