【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 ,本文着重介绍全息干涉法用于液相扩散系数的测定和研究进展更多还原

【Abstract】 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.更多还原
