乙醚

Ether molecules combine with the various components of a Grignard reagent to form complex etherates.

乙醚分子同格里雅试剂分子相连接形成一个复杂的醚和物。

0 G of cyclopentyl bromide and 19.4 g of magnesium are reacted in ether or THF to give a cyclopentyl Grignard reagent.

一百十九点零克的环戊基溴化镁和克一十九点四顷反应乙醚或四氢呋喃给予一个环戊格氏试剂。

The reaction result showed that the reactivity of Grignard reagent was different in THF and diethyl ether when subjected to substitution reaction, which gave three products with different substitution degree.

研究表明，生成的Grignard试剂在THF和乙醚中的反应性不同，与甲基三硅烷或四乙氧基硅烷发生取代反应时生成不同取代度的产物，控制反应条件可得到以单取代、双取代或三取代硅烷为主的产物。

A reaction modle was established,in which the surface reaction being the rate determining step and Langmuir–Hinshelwood type mechanism model being the most ideal model for the ethanol dehydration reaction.

动力学研究结果表明，在实验条件范围内，乙醇脱水生成乙烯和乙醚的反应属于平行反应，符合Langmuir-Hinshelwood机理模型，表面反应为速率控制步骤。

Mascagni were held into a solution containing calcium, ethylene glycol bis-amino tetmacetate and water, respectively. The effects of calcium were studied by measuring the ornamental quality of cut flowers and the physiological characteristics such as calmodulin, abscisic acid, gibberellins, zeatin, endogenous calcium, malondialdehyde and soluble sugar in florets.

以唐菖蒲红色品种'马加烈'切花为材料，瓶插在含有乙酸钙或钙离子专一性螯合剂乙二醇二乙醚二胺四乙酸的溶液中，分析乙酸钙对切花观赏品质的影响以及第1和第3朵小花内钙调素、脱落酸、赤霉素、玉米素、Ca(上标 2+)、丙二醛和可溶性糖含量的变化。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
