介绍了利用激光诱导荧光技术(LIF)测量规整填料内的液体分布的实验方法，实现了液体分布的可视化，得到了液膜厚度和持液量等定量信息。利用LIF技术分别测量了3种物系在750Y型规整填料的实验装置内的液体分布。结果表明，表面张力和黏度都对填料表面上的液体分布有影响，但表面张力对液膜厚度和持液量的影响较大，是主要影响因素。

Laser induced fluorescence (LIF) technique was used to perform experiments of liquid distribution in corrugated structured Perspex packing. The technique was based on continuous detection of intensity of fluorescence change. In order to validate the feasibility of this method, liquid distributions of three systems in 750Y corrugated structured packing were investigated. The LIF technique was very useful not only for the identification of liquid distribution, but also for quantification of liquid film thickness and liquid hold up on the structured packing surface. Both interfacial tension and viscosity of experimental systems could affect liquid distribution but interfacial tension’s influence was more remarkable.
