But for benzene, when treated with SDM-A there was a turning point in its adsorption isotherm, which corresponding to the dividing point between monomolecular and multimolecular layer adsorption.

在用SDM-A处理苯时，出现折线形等温线，折线转折点正是单分子层与多分子层分界点。

It is favorable for the increase of the adsorption film thickness by increasing the lyophobic chain.The determination of adsorption film thickness verifies the validity of the modification result.

木性木在疏水性和亲水性固体表面层厚度不同，其分子疏水链段增加有利于增大其在疏水性（煤）表面厚度。
