电子偶的产生

Two kinds of electron transition processes which lead transition metal complexes to show their colours were discussed.

讨论了导致过渡金属配合物显色的二种电子跃迁过程，只有当电偶极跃迁矩积分的被积函数的对称性允许时，才有可能产生颜色；分裂能的差别，导致跃迁能的不同，因而呈现出不同的视色。

The experimental results from cyclic voltammetry and constant-potential electrolysis show that the mechanism of the reaction was two molecules and three steps electrochemical process with eight-electrons transferred: anion radical arose in the first step; two-electrons were transferred in the second step and accompanied with coupling reaction of radicals and protonation and dehydrate, the main product was azoxybenzene; two-electrons were transferred in the third step, and azobenzene was achieved.

研究结果表明，硝基苯在铂电极上的电还原反应为双分子八电子三步骤电化学过程：第一步反应为准可逆单电子转移步骤，产生阴离子自由基；第二步为二电子转移步骤，并伴有随后的双分子不可逆自由基偶合反应和快速质子化及脱水反应，主要产物为氧化偶氮苯；第三步是二电子转移产生偶氮苯的过程。

An improved OUR equipment was put forward in this paper, and was used in rest measurement. The effects of different environment conditions (temperature、substrate、heavy metal and uncoupled metabolism) to Yobs, YH and Kd were investigated systemically.

本文先提出一种改进的耗氧速率测量装置，以便用于后面实验数据的测量，然后系统研究了不同的环境条件(电子受体、温度、基质、重金属离子和化学解偶联剂等)对表观产率Yobs、真实产率YH以及衰减系数Kd产生的影响。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
