摘要
分析了提取滤膜上粉尘浓度信息的几种方法,以β射线法作参考对比,用光度法测量了滤膜粉尘样品对六种不同波长的光度吸收特性及其衰减系数,从而获得粉尘质量浓度的信息。
Several methods to acquire the information of dust concentration on the filter film are analyzed. The absorption property and the attenuation coefficient for the dust samples on the filter film are measured by photometric method in six colors, with reference to β-ray method. Dust concentration on filter film is acquired.
