摘　　要：探讨用紫外可见光分光光度法研究采样在滤膜上的粗颗粒(PM10-2.5)和细颗粒(PM2.5)的光学吸收特性.结果表明:细颗粒质量虽小,但对光的吸收比粗颗粒贡献大,而粗颗粒对某些波长的光吸收特征非常明显.Using UV-spectrophotometer, the absorption characteristics of coarse particles （PM10-2.5） and fine particles （PM2.5） sampled on PTFE filters were measured. Results show that the mass of fine particles is less than that of coarse particles, while its absorption is much than that of coarse particles, and light absorption characteristics by coarse particles for several wavelengths are very clear.
