1·And I thought molecular weight sounded much less nerdy than molar mass.

我认为分子量听起来不像莫耳质量那么乏味。

2·The term molecular weight is often still used instead of molar mass, but this is not preferred because it can be somewhat misleading.

“分子质量”也常使用来代替摩尔质量，但不倾向使用因为它可能会引起某些误解。

3·With the hexamethylene as solvent and naphthalene as solute, the relative error of molar mass of naphthalene measured is not much as 1%.

以环己烷作溶剂、萘为溶质测得萘摩尔质量的相对误差均在1%以内。

4·Clay stabilizer KS-1, developed for water sensitive oil reservoirs, is organic oligomeric polyammonium salts of medium molar mass in range 3000—5000.

针对低渗水敏性油藏研发的黏土稳定剂KS-1，为齐聚物型有机聚季铵盐，相对分子质量适中，为3000~5000。

5·The resulting polymer's molar mass was still very high and polymer yield and monomer conversion increased a little when prolonging irradiation time to a degree at low power.

在较低的微波功率下适当延长辐照时间，聚合物分子量仍然维持在较高的水平，同时可使聚合物产率和单体转化率有所提高。

6·A device for determining molar mass with freezing point depression was improved, which consists of the Dewar bottle, sample container, Beckmann thermometer, and motor stirrer.

介绍一个改进的凝固点下降法测定摩尔质量实验装置，它由保温瓶、凝固点杯、贝克曼温度计、电动搅拌器等几部分构成。

7·The molar mass proportion of PVK and diazo salt is 1:4. Diazo salt was divided into several parts and added into solution in batches at room temperature to react for 96 hours.

聚乙烯咔唑和重氮盐摩尔质量比1：4，重氮盐按分批加入方式加入到反应液中，反应时间96小时，反应温度室温。

8·The effect of temperature, vacuum, catalyst on the yield of DL la, the relationship between the temperature, time, catalyst content and average molar mass of PDLLA were discussed.

探讨了反应温度、真空度、催化剂对DL LA收率的影响，聚合温度、时间、催化剂用量与PDLLA平均摩尔质量的关系，对它们的结构进行了红外光谱测试。

9·The most detrimental impurities in the feed water are anionic high molar mass substances. They can greatly reduce the efficiency of the retention AIDS or even make them completely ineffective.

为减少水耗可以用循环水，供水中最有害的杂质是阴离子高分子量物质，会大大减少助留剂的效率，甚至使它们完全失效。

10·We invoke Dalton's Law of molar proportions, we write it subject to conservation of mass.

我们援引了摩尔分数的道尔顿定律，要服从质量守恒定律。
