查询词典 ethynyl

To meet the multilayer operation of electro-optical devices, the self-crosslinkable fluorinated 6F-PEEK-PEP, 3F-PEEK-PEP and 11F-PAE-PEP terminated with phenyl ethynyl moieties were prepared successfully.

3F-PEEK和6F-PEEK薄膜在光通讯波段具有两个有较低吸收的"窗口"，也就是说在光通讯波段有较小吸收。

In the first part, one of the side-arms of hexakisbenzene was replaced with a 4-pyridinylethynyl group. Comparing with analogous compounds incorporating a 2- or 3-pyridinylethynyl moiety, the compound with a 4-pyridinyl -ethynyl unit shows lowest melting and clearing points.

中文摘要系列一部分为在六炔苯基苯盘形分子上引入一对位吡啶炔侧臂，在与引入邻位、间位的分子相比较后，发现含对位吡啶炔侧臂的化合物其澄清点温度最低且无热分解问题。

Three series of liquid crystals were synthesized in this study. In the first part of this study, a rectangular liquid crystal, compound 8, with two ethynyl groups and two oxymethylene groups used to link to phenyl groups and biphenyl groups with the central phenyl core respectively exhibits smetic phases.

本研究成功合成出三系列化合物：第一系列为合成以二炔基二亚甲氧基为中心之盘状液晶，并在二亚甲氧基尾端引入可进行光聚合反应之二丙烯酸酯基，得到层列型液晶化合物8，其液晶相温度范围在46.1~74.8℃，且单体8对光与热之稳定性较差，高温下容易自行聚合。

They have close relationship as the former may provide new ideas and approaches for the later, while the later may be the simulation for the former and gives it helps in degradation products identification and mechanism explanation. It is necessary to choose a suitable system, which has high potential of treating EDs and close relationship to the natural environment, to combine the researches in the two aspects. Our group has been engaged in researches on the photochemical properties and application to water pollution control of different ferric species including Fe -OH complexes, Fe -polycarboxylate complexes, Ferric oxides and Fe -humic acid complexes. Fe -oxalate complexes system has higher efficiency than the other ferric species systems in photooxidation and degradation of organic compounds. This thesis is focused on the photodegradation of nine EDs estradiol (E2), estrone (E1), 17α-ethynyl estradiol (EE2), diethylstilbestrol , bisphenol-A , 4-Nonylphenol , 4-Octylphenol , di-n-butyl phthalate , and di (2-ethylhexyl) phthalate .

因此从处理效率和环境化学意义两方面考虑，结合本课题组在不同铁形态（包括Fe-OH配合物、Fe-多羧酸配合物、Fe氧化物、Fe-腐殖酸配合物等）的光化学特性及其在水污染控制中的应用方面较系统的研究工作基础，本论文选择了四类共9种典型的内分泌干扰物（雌二醇（E2）、雌酮（E1）、17α-乙炔基雌二醇（EE2）己雌酚、双酚A、壬基酚、辛基酚、酞酸二丁酯和酞酸二乙基己基酯），研究了它们在Fe-草酸盐配合物体系中的光降解效果，推测其降解机理，探索环境内分泌干扰物光氧化处理的新体系，同时为预测其在环境中的光降解行为提供了依据。

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。
