摘要：

Samples of commercial instant coffee and instant skim milk were exposed to attrition in a tap density tester. Digital images of the projected outlines of individual particles were obtained and the Fractal dimension of their profiles was computed with three different algorithms. Results show that the mean apparent Fractal value of the agglomerates varied with the number of tappings.
