| Abstract: | Powders' particle size distribution fractal dimension could denote size distribution well. Through established the mathematics model to calculate the size distribution fractal dimension which appropriate to the digital microtechnique, discussed the relationship of the powders' fluidity denotation parameters and powders' size distribution fractal value, affirmed that the size distribution fractal dimension could denote the fluidity of the powder, and formed a new method which could measure powders' fluidity compact and reliable. |
