与传统的InGaN构型量子阱结构相比，使用台阶型InGaN构型的量子阱结构，活性区载流子浓度特别是空穴浓度得到明显的改善，输出功率和内量子效率分别提高了52.5%和52.6%。

By using lysozyme, RNase A and protein disulfide isomerase as model proteins, we present a hypothesis that protein cross-linking can be accomplished in three concerted steps:(1) a change in protein conformation;(2) formation of interchain disulfide bonds; and (3) formation of interchain isopeptide cross-links.

我们以溶菌酶、核糖核酸酶A和蛋白质二硫键异构酶为模型对异肽键进行了体外详细的研究，提出了解释异肽键形成机理的假说：1蛋白质发生构象变化包括二级结构的改变；2蛋白质形成分子间二硫键：3二硫键的形成帮助蛋白质形成了分子间异肽键。

Adduct G is isomerized by F. The isomerization energies are relatively high (in the gas phase: 244.77 kJ/mol; in solvent of water: 234.83 kJ/mol), which is consistent with the experiment that adduct F is the primary alkylation product.

加合物G由F异构形成，且有相对高的异构化能（气相：244.77 kJ/mol；水溶剂中：234.83 kJ/mol），这与实验上得到加合物G是主要癌变物的结果一致。

In catalytic cracking, the enlarged space in which hot oil is contacted and cracked with the catalyst; in isomerization, the vessel containing catalyst in which the hydrocarbon is isomerized; in alkylation plants, the vessel containing emulsified acid in which most of the alkylation occurs.

在催化裂化中是热油与催化剂接触并进行裂化的扩大空间；在异构化中含有催化剂的容器是烃类进行异构化的场所，在烷基化装置中是发生大部分烷基化反应的含有乳化酸的容器。

Cis-C=C configuration on 2 position is easily isomerized to trans-form in environment according to literatures, but cycloproyl do it difficut relatively. So, replacement of 2,3- allyl unit by cyclopropyl group might give a practical method to get over the problem.
