"certainly not," uncle chunfa said evenly . “当然不带,”春发叔淡然地答道。
They were also asking sly questions at australia's . 对澳叔的情况他们也拐弯抹角打听。
Isomeric alcohols, tertiary amines are less water soluble than their isomeric primary and secondary amines . 异构的醇,叔胺的水溶性比其异构的伯胺和仲胺小。

Isomeric alcohols, tertiary amines are less water soluble than their isomeric primary and secondary amines . 异构的醇、叔胺的水溶性也比其异构的伯胺和伸胺小。
Thus varying the nature of r from primary to secondary to tertiary alkyl results in increasing yields of the hydroxy ethers . 当R按伯、仲、叔烷的顺序递变,则所得羟基醚的产率就随之而增高。
Many drugs and pesticides contain tertiary amino groups and could, therefore, be expected to undergo nitrosation in the body . 有很多的药物和农药含有叔胺基团,因此有可能在体内发生亚硝基化。
Tertiary amines, although basic, fail to yield amides, presumably because they cannot lose a proton, (to stabilize the product)after attaching themselves to carbon or to sulfur . 叔胺虽然呈碱性,但不能产生酰胺,这大概是因为当它们连在碳或硫上之后,无法失去一个质子(以稳定产物)的缘故。
You don ' t save your uncle ? i ' ll let you eat epsom salt 阿叔都不帮,给你点泻药
