The penetration of a particle into the lung is influenced by air velocities breathing patterns. 颗粒物对肺的穿透作用受气流速度和呼吸形式的影响。
It is found that the entraining water flux decreases at first, reaches a minimum, and then increases with the increase of the liquid film velocity. 在两管间隙和气流速度一定的条件下，液膜流速对气流的带液量也存在影响，随着液膜流速的增大带液量先减少后增加。
