| 摘 要： | 本文提出一种测定粉末粒度的新概念,采用颗粒各平表面到其中心按表面积加权平均距离的两倍来描述粉末颗粒大小,和传统的方法相比较,具有不需假设粉末颗粒为某种规则形状的前提条件,从而可较为准确的描述和表征形状复杂的颗粒尺寸,并且具有检测方便的特点。

| Abstract: | A new idea of determination of powder particle size has been found,which can get the powder particle size through double of weighted average from the particle surface to the center of it.And comparing with the traditional method,it isn't on the premise of that suppose powder particle possessed with any regular shape.Thus it is more accurate to describe and express particle size with complicated shape,and has the merits of detecting conveniently. |
