在目前常用的激光粒度仪反演算方法的优点和缺点基础上，为了实现各种方法的稳定性

与准确性的统一，提出一种基于退火演化算法和遗传算法组合的随机反演方法，该方法具有更

强的全局收敛性，也具有对粒径分布形状不敏感、抗噪声能力强等优点。该算法能对具有单峰

及双峰分布形式的颗粒尺寸进行精确求解，并获得合理的颗粒粒径分布结果。-, In order to achieve the unity of the stability and accuracy of the various methods used laser particle size analyzer anti-calculus methods advantages and disadvantages based on the the random inversion method based on the annealing evolution algorithm and genetic algorithm combination, the method stronger global convergence, but also has the shape of the particle size distribution is not sensitive to the ability of anti-noise. The algorithm can accurately solved with a single peak and bimodal distribution in the form of particle size and particle size distribution results reasonable.
