摘　　要：气溶胶辐射强迫效应的正负在很大程度上取决于其复折射指数虚部的大小。运用干涉光谱和Mie散射理论,分别在相同粒径粒子和不同粒径粒子两种情况下,推导出了干涉光谱和气溶胶复折射指数之间的关系式,初步建立了干涉光谱方法测量气溶胶复折射指数的理论模型,并对探测限进行了讨论。研究表明:干涉光谱方法测量气溶胶的复折射指数在理论上是可行的。Aerosols radiation forcing mostly depended on the imagery of complex refractive index. With interferometric spectrometer and Mie theoretics, the theoretical model of interferometric spectrometer method for aerosols complex refractive index was built up in two conditions： similar radius particles and different radius particles, and the detections limit of complex refractive index is discussed at first glance. It shows that the complex refractive index of aerosols particle measured by interferometric interferometer is feasible and promising.
