查询词典 entrainment

Elutriation refers to the selective removal of fines by entrainment from a bed consisting of a mixture of particles sizes.

扬析是指从由各种颗粒直径的混合物形成的床层中选择地夹带出细粉颗粒的过程。

The self-excited oscillation imposes a profound influence on turbulent mixing process: i.e., it not only enhances large-scale engulfment or entrainment but also simultaneously decreases the molecular mixing rate.

射流振荡对近场和远场的湍流混合过程都具有重要影响。自激振荡射流能增强宏观上的大尺度搅动，但同时却减弱了微观上的小尺度混合。
