摘　　要：本文概述了多孔介质中粘性指进现象的研究成果，并对Ｈｅｌｅ－Ｓｈａｗ装置的模拟和三维多孔介质实体的实验进行了评价；介绍了分形学的基本概念以及近年来在指进研究中的应用．最后，对研究粘性指进与分形学的关系提出了一些建议．In this paper, first of all, a review is madc on some importantachievements in the studies of viscous fingering phenomena in literature, toge-ther with a iiscussion on the simulation with Hele-Shaw device and in the bedof three-dimensional porous media. Consequently, the basic concepts of fractaland its applications in the studies of viscous fingering phenomena in recentyears are introduced. Finally, some suggestions for the research on viscousfingering and fractal are made.
