qac的翻译

Modifying Bentonite and Attapulgite with on short chain quaternary ammonium compound ( QAC) tetramethylammonium ( TMA) has been done. The sorption of benzene homologues in simulated groundwater by TMA modified clays has been studied.

用短链季铵盐阳离子表面活性剂四甲基铵离子（TMA）改性膨润土和凹凸棒土，研究它们对模拟地下水中苯系物的吸附作用。

Quadrilateral Area Coordinate ( QAC) method is a new tool for developing 2D quadrilateral finite element models which are insensitive to mesh distortion. But this new system can not handle curved-side cases directly.

四边形面积坐标方法是一种构造二维四边形有限元模型的新工具，为解决单元网格畸变敏感问题提供了新途径，但是这种方法还不能直接模拟曲边网格的情况。

The effects of modifiers on the extraction of Co(ⅱ), Fe(ⅱ) and Mn(ⅱ) with quaternary ammonium chloride ( QAC) were investigated.

研究了改性剂对季铵盐萃取分离钴（Ⅱ）、铁（Ⅱ）、锰（Ⅱ）的影响。
