| 摘 要： | 本文介绍了国内外光学全散射法测粒技术的发展过程、存在的主要问题,提出一改进后的新方法:用多波长全散射法测量颗粒粒径分布。该方法不仅可消除全散射法测量结果有多值性的缺陷,而且可以直接获得颗粒的粒径分布,测试粒径范围也有所扩充(0.03～8μm)。文章还给出了用独立及非独立模式的两种算法,求解粒径分布的数值模拟结果以及对聚苯乙烯标准颗粒的实测结果。计算和实测的结果令人满意。

| Abstract: | This paper focuses on the development, process and existing problems of the particle size measuring techniques with the optical means of total scattering. An improved total scattering method has been developed which not only eliminates the ambiguity of the measurements but also offers the size distribution of the particles to be measured. Two calculating methods, i. e. the dependent model and the independent model, are presented. Numerical calculations and computer simulations are also given. The measurements of polystyrene spheres as standard reference material are given at the end of this paper. |
