摘要
研究了两种粒子计数器,其中以光散射为原理的粒子计数器测量的是光学等效直径,测量结果受折射率的影响很大;以粒子飞行时间为原理的粒子计数器测量的是空气动力学直径,测量结果不受折射率的影响.利用两种仪器的同时测量结果来计算大气的折射率,并给出计算结果.
Two types of particle counters are described in this paper.The one measuring optical sizing of aerosol particles is greatly influenced by refractive imaginary part.The other one measuring aerodynamic sizing of aerosol particles is not influenced by refractive imaginary part.Based on the measurements with two types of particle counters,calculation of inverse refractive imaginary part is given.
