【摘要】 通过燃烧微粒单色透射率光谱的测定，考虑实验时粒子中实际存在的影响，通过透射率、消光因子等参变量与Ｋｒａｍｅｒｓ－Ｋｒｏｎｉｇ（简称Ｋ－Ｋ）关系式的联立求解，得到燃烧微粒的复折射指数，因为此种方法考虑了散射对实验粒子的作用，因此以此复折射指数计算出的燃烧微粒的辐射特性参数具有更高的可信度．更多还原

【Abstract】 The approximate Mie theory and Kramers Kroning relation (K K relation) were combined to derive the complex refractive index of particles from the transmitting spectrum measurement. As the scattering of particles was taken into account, the radiative properties parameters of combustible particles calculated with the complex refractive index possesses higher confidence.更多还原
