| 摘 要： | 运用微粒散射形体微扰理论对任意形体微粒的研究结果,根据光敏区光强的Gauss分布特征和微粒穿越位置的随机性,建立了相关模型和数学方程并求得了任意位置的微粒形体影响因子分布函数的数值解,讨论了大变化区的非线性影响.其次,根据微粒数分布离散性的特征,建立了微粒粒度分布函数的反演矩阵及其实验方法.最后进行了实验验证.

| Abstract: | A new inversion equation is built upon the particles' scattering theory and its shape influence. The probability distribution function of particles' size,the shape factor function and the distribution function of particle shape are further studied.Firstly,a model and an equation are built upon the characteristics of the Gaussian scattering cavity and the location pobability,a result is obtained from it and the nonlinear influence in a wide range is studied.Secondly,the inversion matrix equation of the particle size distribution is obtained from the discrete characteristics of the particle distribution in both mathematical theories and experiments.At last, a numerical experiment is made to test the method. |
