In order to study the regular pattern of Mie scatter，a high-accuracy algorithm of the continued fraction forward recursive is presented.The single particle and particle swarm are discussed by virtue of programming calculation of the matlab.It focuses on the influence of the absorbency of spherical particle and the particle size distribution on the light scattering regular pattern，when the incident light is the plane polarized light.And it shows the regular pattern of Mie scatter intuitively，which is helpful to research and utilization of the Mie scattering theory.
