查询词典 surfactant

The unexpected oxygen surfactant in previous STM experiment[3] possibly come from longer experimental time, STM sample holder outgasing, and smaller Co coverage.

这个在STM实验[3]中未预期的曝氧效果其可能的发生原因为较长的实验时间、STM样品架於升温时吐气和较少的Co覆盖量。

With the development of science and production,people manufacture better "soap"-synthetic detergent,its species are increasing,and the scope of application is beyond the field of "washing".Such substances should not have been easy to "soap" and "detergent",but to "surfactant".

随着科学和生产的发展，制造出更好的&肥皂&——合成洗涤剂，其品种和产量不断增加，应用范围远远超出了&洗涤&领域，这类物质已不能简单地以&肥皂&和&洗涤剂&来称呼，而以&表面活性剂&这一名词来统称。

In the current study, anoxic dechlorinations of p, p'-DDT,γ-HCH, HCB in the Liao River sediment were studied under the following conditions: without any additional short chain carbon substrates or vitamin B〓; with the addition of short chain carbon sources (including sodium lactate, sodium propionate or sodium acetate); with the addition of vitamin B〓; with the addition of both short chain carbon substrates and vitamin B〓, with the addition of sodium dodecyl sulfate , a kind of surfactant; the coexistence of the three chlorinated compounds.

氯代有机物一般都是典型的持久性环境污染物，其中部分氯代有机物还是环境激素类物质，例如，滴滴涕、林丹和六氯苯等，这些氯代有机物在环境中的迁移转化一直是国际环境化学领域的热点、重点课题。氯代有机物进入环境水体后，成为沉积物吸附态有机污染物的重要成分，天然水沉积物经常处于缺氧状态。因此，研究氯代有机物在天然水体沉积物中的缺氧脱氯行为是非常必要的。

In the current study, anoxic dechlorinations of p, p'-DDT,γ-HCH, HCB in the Liao River sediment were studied under the following conditions: without any additional short chain carbon substrates or vitamin B〓; with the addition of short chain carbon sources (including sodium lactate, sodium propionate or sodium acetate); with the addition of vitamin B〓; with the addition of both short chain carbon substrates and vitamin B〓, with the addition of sodium dodecyl sulfate , a kind of surfactant; the coexistence of the three chlorinated compounds.

本文分别采用不外加碳源和维生素B〓外加碳源（包括乳酸钠、丙酸钠或乙酸钠）、外加维生素B〓以及同时外加碳源和维生素B〓的方法，考察了p，p'-DDT、γ-HCH和HCB三种氯代有机污染物单独或混合存在下，在辽河沉积物中缺氧脱氯降解的情况，主要得到以下结论
