颗粒群粒度分布宽度表示方法的研究

Research on Representations of Particles Size Distributional Width

总结了传统的粒度分布宽度的表示方法,分析了它们的适用场合。通过理论推导,提出了一种表示粒度分布宽度的新方法--颗粒群的分形维数。颗粒群的分形维数D可定量描述粒度分布宽度。分形维数D越大,颗粒群的粒度分布越宽。

Traditional representations of particle size distributional width were summarized and their applicable cases were analyzed. Through theoretical deduction, a new method for describing particle size distributional width, named fractal dimension of particles, was put forward. It could describe particle size distributional width quantificationally. The larger the fractal dimension was, the wider the particles size distribution was.
