gas diffusion velocity

基本解释

The diffusion deposition of aerosol particle went against the increasing of gas velocity.
气体流速的增加不利于粒子的扩散沉积；
The analysis indicated that the superficial gas velocity and catalyst recycle intensity were two main factors, which influenced the diffusion behavior of gas in the bed.
分析表明，表观操作气速和催化剂循环强度是影响床层内气体扩散的主要因素。
Recently, the research of the dependence of ion movement on ion diffusion and carrier gas velocity distribution in high strength electric field has achieved preliminary results.
目前国内外对高电场中离子扩散、载气流速分布对离子运动行为的影响进行了大量的研究，取得了一定的研究成果。
