查询词典 chloric ether

The article explained the study on oil extraction with petroleum ether (60~90℃) from Xanthoceras sorbifolia Bunge. through single factor test and orthogonal test. It confirmed the optimum extraction condition were as follow: particle size 2 mm,extraction temperature 90℃,extraction time 10 h,ratio of solvent to seed 5:1.

摘要以石油醚（60~90℃）为溶剂，通过单因素和正交实验优化了提取文冠果种子油工艺，得到的最佳工艺参数为：种仁粒径为2 mm，提取温度为90℃，提取时间为10 h，料液比为1：5。

To examine the effect of surfactant adsorption on physical stability of flowable concentrates used for coating seeds with pesticides, high performance liquid chromatography was used to analyze the adsorption of a surfactant (the nonylphenol ether, Witconol NP-100) on thiram and carbofuran particles.

采用高效液相色谱仪研究了水悬浮液中烷基酚聚氧乙烯醚(Witconol NP-100)在福美双和克百威两种农药颗粒表面的吸附性能，并探讨了表面活性剂在农药颗粒表面的吸附对悬浮种衣剂的物理稳定性的影响。

The petroleum ether fraction was analyzed by GC/MS resulting in the identification of 15 acyclic compounds, 6 other chemical constituents including terpenoid and sterol.

运用GC/MS分析技术从石油醚相中鉴定了15个脂肪酸类化合物，6个倍半萜及甾体类等化合物。

For the research on chiral discrimination of soluble polymer-supported tartrates as stationary phases of CGC, one of the ligands, di (polyethylene glycol monomethyl ether) tartrate was used as stationary phase and a column was prepared.

为研究可溶性聚合物支载的酒石酸酯作为气相色谱固定相的手性识别能力，配体之一酒石酸二酯被用作固定相制备成色谱柱。

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。

The results showed that there were significant differences between two different periods of pigs (P.05) in apparent digestibility value of crude protein, crude fiber, nitrogen-free extract, ether extract.

结果表明，在20~50㎏阶段，除虫菊花渣的粗蛋白、粗纤维、无氮浸出物和粗脂肪的表观消化率分别为45.78%、24.27%、79.49%和53.55%，表观消化能为8.53MJ/㎏；在60~90㎏阶段，其CP、CF、NFE和EE的表观消化率分别为56.29%、40.52%、79.66%和64.62%，DE为9.16MJ/㎏。

I believe these magical devices called Ether Traps should protect me if only I can trick the spectres into them.

我相信称以太的陷井的这些不可思议的设备应该保护我，但愿我可以欺骗幽灵入他们。

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.

事实上，我们已经从一种Lewis酸催化下的低电位聚合体系—噻吩/三氟化硼乙醚溶液中得到了高质量的聚噻吩薄膜，在降低了的聚合电位下得到的聚合物具有优异的力学及电学性能：拉伸强度达140MPa(比金属铝高40%)，电导率则可达100Scm-1。
