The invention provides an inversion method for spherical particle fractal aggregation characteristic parameters based on continuous laser multi-angle scattering measurement and aims at obtaining a method for measuring suspension spherical particle fractal aggregation characteristic parameters. During an experiment, continuous laser is adopted for irradiating the surface of one side of a particle system, a detector is used for measuring a multi-angle scattering measurement signal of the other side of the particle system, spherical particle size distribution is measured and obtained by utilizing a particle size analyzer, a spherical particle optical constant is obtained by utilizing a Fourier spectrum analyzer, a Mie scattering theory, a Kramers-Kranigs relation and an artificial bee colony optimization algorithm, and finally the spherical particle fractal aggregation characteristic parameters are indirectly obtained based on the multi-angle scattering measurement signal and combining an inverse problem solving technique. By building forward and inverse problem models used for measuring the spherical particle fractal aggregation characteristic parameters, under the premise that other physical property parameters of particles are known, the invention provides a method for obtaining the spherical particle fractal aggregation characteristic parameters through inversion by combing a multi-body T matrix theoretical model with the artificial bee colony optimization algorithm.
