摘　　要：用空气－热水系统在φ１０５ｍｍ塔内进行热质传递试验，结果表明，聚丙烯填料经液相化学法处理后，体积传质系数ｋ＿Ｈ·ａ可增大２５％左右。The experimental study of simultaneous heat and mass transfer perform-ance of hydrophilised polyprophlene packings has been made in a column of 105 mmdiameter with the air-hot water system.After the polypropylene packings was hydro-philised by chemical treatment in liquid phase,the results show that the mass trans-fer coefficients k_H·a of that packings can be increased about 25%.
