METHODS ：Combined with the results by transmission electron microscopy and contrasted with the sample without dispersant ，the influence of polysorbate 80 as dispersant and other factors of dispersed system on the determination of particle size of ABZ liposome by laser scattering method were investigated. RESULTS ：The average particle size of samples with- out dispersant by laser scattering method was （663.5±93.0）nm ；that of samples was （240.6±2.8）nm under optimum dispersing condition ：i.e. the volume ratio 10％polysorbate 80 to ABZ liposome was 4∶1，and was diluted by 0.9％sodium chloride for 20 times ；that of samples was 226.5 nm by transmission electron microscop
