    摘要
  • 摘要: 介绍一种通过投影面积来测定粉末平均粒度的方法。由一束均匀的平行光通过已知重量和密度、分布于液体介质中的粉末体,用光电元件检测其遮光面积,从而计算出粉末的平均粒度。同时介绍了仪器的结构。实验结果表明,投影面积法的测试结果与费氏法接近,并具有较好的重复性。
    Abstract: The present paper has described the determination of average particle size by projection area method, i.e.a beam of parallel light was passed through the powder with given weight and density which was distributed in liquid medium. The photochopping area was measured by projection area apparatus, so that the average powder particle size was enabled to determine. The structure of apparatus has been illustrated. Experimental results have shown that the results obtAlNed by this method are similar to those by Fisher method and exhibit superior reproducibility.
