These nanometer particle effects have been interrelated by author in terms of adsorption concentration effect, adsorption orientation effect and quantum size effect.
作者用纳米颗粒的吸附浓集效应、吸附定向效应、和量子尺寸效应来解释这些效应。
Although the thermophoresis force could affect the 50-micron particle, the concentration did not change as large as 2-micron particle because of the large mass and the wall effect.
热泳力对粒径为50微米的颗粒也有影响，但是由于颗粒的质量较大，再加上壁面效应，其作用效果远没有2微米颗粒明显，仅在近壁区颗粒的浓度略有升高，而其它部分基本不变。
Under non-stationary filtration condition, firstly the study about the effect of particle concentration, filtration velocity and filtration time on pressure drop was taken.
