Abstract
Based on the quantitative stereology theory，the quantitative characteristics of particle group such as particle size distribution，roundness are determined by using image analysis．T he experiment parameters of quantitative stereology theory such as minimum samples，grey threshold are also studied．T he experiment results show that the characteristics of 3-Dmicrostructure can be precisely obtained by using the theory of quantitative stereology and the method of image analysis，and the results have higher reliability．
Keywords：characteristics of particle group；quantitative stereology；image analysis
