The activation by monovalent ions is at least partially due to removal of the inhibition by an excess of Mg〓.

一价阳离子的激活作用至少部分是源于对高浓度镁离子抑制作用的拮抗效应。

Halogen atoms contain seven electrons in their valence shell, and, consequently, are monovalent

卤原子在它们的价电子层含有七个电子，因此是一价的。

In this connection, Ar3 and Ar4 independently represent an optionally substituted monovalent aromatic ring.

在这一点上，Ar3和Ar4各自独立地表示任选被取代的一价芳族环。

In the consideration of dual economy, this paper applies one price law theory to general consumer price index and general retail price index, and separately inspects the city department and the countryside department's marketization degree.

在考虑二元经济特征的情况下，应用一价定律理论，以居民消费价格指数和商品销售价格指数作为衡量指标，分别考察了城市部门和农村部门的市场化程度。

Toxicity characterisation procedures indicated that the primary toxicants in the effluent were volatile,and could be reduced by sodium thiosulfate. Toxicity based fractionation techniques were conducted,and the oxidation organic chloridates were found not to be the major toxicants.

结果表明，废水对大型蚤具有急性毒性，曝气可去除废水的部分毒性，硫代硫酸钠的投加可去除废水毒性，同时用DPD试剂盒比色法可测出游离态氯气和一价氧化态氯化物。
