摘要 利用广义洛伦兹米氏理论 ,研究了多层球折射率按指数规律变化时 ,其一阶彩虹角分布随折射率变化的情况。研究结果表明 ,无论折射率为指数增大还是指数衰减 ,多层球彩虹角位置均与折射率分布密切相关 ,为探测非均匀球的折射率及梯度分布以及燃烧室的温度分布提供了有效的信息。 The first rainbow of multilayer spheres is studied, whose profiles of the refractive index are exponential decrease or increase by using generalized Lorentz-Mie theory of multilayer sphere. The results obtained demonstrate that the angle positions of the rainbow of the multilayer sphere is sensitive to the refractive index profile, whether the refractive index exponential decrease or exponential increase. The results are very useful to probe the refractive index, its gradients and temperature of the combustible particle.
