摘　　要：液相扩散系数是研究气 -液、液 -液和液 -固传质的重要物性参数 ,由于理论预测和各种估算方法还不成熟和完善 ,因此其实验测定方法尤其受到人们的关注和重视。激光全息干涉法是一种新型的现代光学测量方法 。Liquid diffusivities are the important paramenters in the study of mass transfer in gas-liquid,liquid-liquid and solid-liquid systems.Due to the imperfection of the theoretical prediction and empirical evaluation,the experimental methods have been paid considerable attention by the researchers in this field.Laser holographic interferometry is a new method in the modern optical measurement.This article introduces the application and progresses of holographic interferometry to the measurement of liquid diffusivities.
