DLS 动态激光光散射 When a broad distribution of spheres is present in the sample eq. 5-1 must be modified before data analysis of the measured ACF can proceed. Each size contributes its own exponential, and the mathematical problem becomes Lognormal Multimodal Size Distribution(MSD) School of Chemistry, SYSU
