查询词典 sampling fraction

Firstly, to the particulate filled Polyurethane composites, we have detected the contact angle between test solvent and filler or polymer matrix by the surface analysis. The surface tension, polar force parameter of the surface tension, apolar force parameter of the surface tension and polar fraction had been calculated.

通过表面分析的方法，测出参比液在基体与填料表面的接触角θ，计算出其表面张力γ_s、表面张力的极性分量γ_s~p、非极性分量γ_s~d、极性分数P；并由此估算出了基体与填料所形成的界面的界面张力γ_、粘附功W_a、裂纹能γ_G。
