摘　　要：从压力扩散出发 ,提出了表面张力对相际传质的影响机理 ,并且探索性地给出了表面张力对相际传质影响的数学描述。最后 ,文章还结合工业上应用的情况 ,指出了表面张力在除氧器雾化加热区和鼓泡区对除氧过程的影响 。Based on the principle of pressure gradient diffusion,the mechanism of the influence of surface tension on interphase mass transfer was brought forward,and a mathematical description of the influence was presented exploringly.Finally,relating to industrial applications,the influence of surface tension on oxygen deaerating in the atomizing section and in the bubble section was introduced,and the influence of surface tension on atomizing absorption was pointed out as well.
