当量浓度

为了确保各组小鼠对当量浓度的EBD都能吸收进血液循环，及腹腔注射的泄漏程度，我们检测了血浆中EBD的浓度。

In order to ensure that each group of mice can absorb the equivalent concentration of EBD into the blood circulation , and intraperitoneal injection technology , we examined plasma EBD concentration .

河水中HCO3-与Ca2+占主导地位，占总离子当量浓度的55%以上，主要受到碳酸盐类溶解的控制。

According to the principal composition analysis of river water , water chemistry is mainly controlled by the dissolution of calcite , which is responsible for mostly HCO 3 - and Ca 2 + accounting for55 % of total ion equivalent concentration .

对辽宁省7个市区的办公室和居室内空气氡浓度水平进行了调查研究，结果表明，办公室室内空气中氡的平衡当量浓度为39.3/Bq·m-3。

Radon density indoor is investigated in 7 urban district of Liaoning . The result indicates : Radon balanced equivalent density in office is 39.9/Bq .

当量浓度的废除与滴定分析的计算

Abandoning normality and the calculation of titrimetric analysis

讨论了废除当量浓度，采用物质的量浓度的优越性。对所谓等物质的量反应规则及其计算公式进行了剖析，说明其不宜作为滴定分析计算的依据。

An Introduction to Equimolecular Reaction Mechanism and the Method of Volumetric Analysis The necessity of abandoning normality and the advantage of using amount of substance concentration have been discussed .

在分析我国天然本底辐射水平数据的基础上，推荐了室内外γ辐射剂量率、氡和子体平衡当量浓度的典型值。

分析生物测试的结果，发现灌溉土壤中芳烃受体效应物质的毒性当量浓度最高达97.4ng/kg，明显高于地下水灌溉背景土壤（56.0ng/kg）。

By bioassay , it was found that the concentration level of Ah-receptor agonists in soil irrigated using reclaimed water could be as high as 97.4 ng / kg , which was obviously higher than that in background soil using ground water irrigation regime ( 56.0 ng / kg ) .

比对结果总的毒性当量（浓度）值（TEQ）第一年不满意，第二年为满意。

Z-scores in first round for total TEQs were unsatisfied , but in second round they were satisfied .

土壤中二恶英浓度和毒性当量与EC浓度没有相关性，进一步表明了焚烧过程并非是珠江三角洲地区二恶英污染的主要污染源。

The bad correlation between the concentration of dioxins and EC in the soil / sediment was detected , which furthermore showed that the combustion process was not the main source of dioxins in the Pearl River Delta .
