乙醚

After the completion of reaction, ether is added to the resulting mixture to precipitate the tartrate and filter to recover the ligand. The recovered ligands keep good enantioselectivity only in first recycle, but compared with solution-phase of tartrate counterpart, using of soluble polymer-supported tartrates largely simplifies the workup of sharpless epoxidation.

反应完成后，向反应体系中加入乙醚使配体沉淀，过滤即可回收配体，虽然回收的配体只在第一次循环中保持了较好的对映选择性，但与使用小分子酒石酸酯配体相比，使用可溶性聚合物支载的酒石酸酯极大地简化了Sharpless环氧化反应的后处理。

In fact, we had obtained polythiophene films with high quality in BF3 ethyl ether, a kind of solvated Lewis acid. The electric conductivity of the polythiophene film is a bout 100 Scm-1. and the tensile strength is as high as 140 MPa, which is forty percent higher than that of aluminum.

To give Celine designer Ivana Omazic her due, she accurately registered all these movements in the fashion ether, while giving them a kind of sports spin—a cashmere hoodie and fur-smothered parka here, a crocodile motorcycle jacket there, and a couple of luxury rucksacks inserted into the back view of raincoats.

为了让席琳设计师伊万娜格Omazic尽责，她准确地登记时尚乙醚中的所有运动，同时给他们一种体育附带一——开士米羊绒和毛皮被窒息的附头巾皮外衣，摩托车鳄鱼夹克，一些豪华背囊插入背面的雨衣。

In this study we sought to determine whether exposure to theanesthetics diethyl ether and isoflurane influences the activityof hepatic cytochrome P450 2E1 and P450 reductases in the rat.

通过这项研究，我们试图去确定用乙醚或异氟醚麻醉是否影响肝脏细胞色素酶 P450 2E1和 P450还原酶的活性。

If the lens is composed of plastic lenses, it is best not to use the lens of water, do not use alcohol to clean the mixture of ether plus lens.

如果镜头是由塑料镜片组成的，那最好还是不要用镜头水，也不要用酒精加乙醚的混合液来清洁镜头。
