简单介绍了乙炔法合成氯乙烯的反应原理、工艺流程、操作条件和主要技术指标，以及氯化汞催化剂的规格和制备方法，讨论了氯化汞催化剂的缺陷，总结了在减少汞流失方面对氯化汞催化剂进行改良的进展情况。

The suitable range of gas flow ratio is dependent on substrate temperature.

不同衬底温度下氧气与乙炔流量比的范围是不同的。

Prevent the fusible metal plugs on the adjacent cylinders from becoming heated, melting, and

近钢瓶的易熔金属塞受热、熔化和排放出额外的乙炔，这是非常重要的。

The structure and properties of soluble polyacetylene obtained with rare-earth catalyst are thoroughly investigated by UV, IR, Raman spectroscopes, ESR and X-ray diffraction.

本文利用UV、IR、Ramaan、ESR和X射线衍射等方法研究了可溶性聚乙炔的某些结构特征。

Group A = atmospheres containing acetylene; Group B = atmospheres containing hydrogen; Group C = atmosphere containing ethyl-ether vapors, ethylene, or cyclopropane; Group D = atmospheres containing gasoline, hexane, naphtha, benzene, butane, propane, alcohol, acetone, benzol, lacquer, solvent vapors or natural gas.

组A =大气中含有乙炔；组B =大气中含有氢；组C =大气中含有乙醚蒸汽，乙烯，或环丙烷；组D =大气中含有汽油，乙烷，石脑油，苯，丁烷，丙烷，酒精，丙酮，不纯苯，漆，溶剂蒸汽，或天然气。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
