推导了晶体粉末的漫反射系数与颗粒大小、折射率和绝对光吸收系数之间的关系式。用该方程计算的KCl：Tl、KBrTl和Dy玻璃的漫反射吸收光谱与同一材料透明晶体的绝对吸收测量结果令人满意地符合。
An equation relating the diffuse reflectance of crystalline powders to particle size, index of refraction, and absolute optical absorption coefficient is derived. Absorption spectra calculated by means of this equation from diffuse reflectance of KCl:Tl, KBr:Tl, and didymium glass are shown to be in satisfactory agreement with absolute absorption measurements on clear crystals of the same materials.
