| 摘 要： | 我们利用Junge谱对多道光电粒子计数器的测量谱进行了模拟,根据光散射的米氏理论,考察了气溶胶小粒子对其消光、后向散射及消光后向散射比的影响情况,对估计由实测谱及折射指数计算以上三个参量所带来的误差具有一定参考价值.

| Abstract: | Using Junge spectrum approximation we simulated the measured particle size distribution with a multiple-channel-optoelectronic counter. On the basis of Mie theory of light scattering, we studied the effects of size-interval on aerosol extinction, backscatter and the ratio of extinction to backscatter. The results are useful to estimate the errors caused by the calculations by using measured particle size distribution and refractive index . |
