一价酸

A compound derived from ammonia and containing the bivalent NH group combined with a bivalent nonacid group.

亚胺源自氨的一种化合物，含有与一个二价非酸基结合的氨基

By first esterification reaction, the acid value of deodorizer distillates can be reduced to 30-40mgKOH/g from 145mgKOH/g.

在上述条件下，经一次酯化，脱臭馏出物酸价可从约145mgKOH／g降到30-40mgKOH／g。

Sodium dichromate dihydrate is an inorganic compound containing hexaalent chromium that was used in the NTP studies.

重铬酸钠是NTP在研究中使用的一种含有六价铬的无机化合物。

Any of several esters, other than the ethyl ester, of carbamic acid .

亚胺源自氨的一种化合物，含有与一个二价非酸基结合的氨基

In order to mimic this repair process of apoenzyme, we synthesized two model compounds, in which tryptophan and/or tyrosine was covalently linked to cyclobutane thymine dimer, and measured the splitting quantum yield of dimer under 295 nm light. By investigating the photosensitized splitting properties of the dimer, some new insights into the intramolecular electron-transfer process were gained.

为了模拟酶蛋白的这一修复过程，合成了色氨酸和/或酪氨酸与胸腺嘧啶二聚体共价连接的化合物，作为酶-底物复合物的模型，研究了它们在295 nm光照射下氨基酸残基光敏化二聚体裂解的性质，测定了二聚体裂解量子产率，获得一些新的结果并对其进行了分析。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
