| Abstract: | According to the analysi s of the measurement error of particle s ize analyzer,we found that the main reas on of mistake judgement was multi peak s cattering spectrum.Several factors could produce the multi peak scattering spect rum,such as optical unsymmetry of partic les,shape of the particles,beam profile un uniformity.This paper proposed a inte grating judgement method to avoid the mi stake judgement. |
