Abstract：Based on the fractal dimension （FD），a generalized fractal model which is suitable for quantitatively analyzing the shape of powder particle is proposed．Its features and the real－ time estimating method are studied．With the help of S600 image processing system，the SEM image of powder particle is investigated．By using intellective FD analyzing technology proposed，the shape of particle，the effects of particle shape on powder property are investigated．The result shows that，by means of the intellective FD method，the shape of powder particle，the statistical distribution features can be quantitatively described． 

Key words：fractal dimension；fractal model；particle shape
