研究了通过小角 X 射线散射 (SAXS) 和透射电子显微镜 (TEM) 测定的相互作用硬球样品的粒度分布。通过将 Porod 区域拟合到由球体直径的高斯分布涂抹的均匀电子密度球体的形状因子，根据 SAXS 数据确定样品中的多分散性。我们发现 SAXS 测定的粒度分布与 TEM 图像分析计算的粒度分布非常吻合。
Particle size distributions determined by small-angle X-ray scattering (SAXS) and transmission electron microscopy (TEM) are investigated for samples of interacting hard spheres. Polydispersity in the samples is determined from the SAXS data by fitting the Porod region to the form factor of a sphere of uniform electron density smeared by a Gaussian distribution of sphere diameters. We find good agreement between SAXS-determined particle size distributions and those calculated from TEM image analysis.
