A method has been devised, based on the Kubelka-Munk theory of diffuse reflectance, for obtaining an estimate of the optical absorption coefficient of a finely powdered material that has been collected on the surface of a membrane filter. The procedure does not require any knowledge of either the real refractive index or particle size distribution of the material. No mechanical or chemical processing is involved, and only one sample is required. Results are presented.
基于库贝尔卡-蒙克漫反射理论，已设计出一种方法，用于估算收集在膜过滤器表面的细粉状材料的光吸收系数。该方法不需要了解材料的实际折射率或粒径分布。不涉及任何机械或化学处理，仅需一个样品。给出了结果。
