Based on the expended coupled phase(ECP) theoretical model, through the numerical analysis of ultrasonic attention in high concentration TiO_2-Water and Micro-bead-Water suspensions, the influence of frequency, particle size and volume concentration on ultrasonic attenuation is analyzed so as to offer theoretical support for the measurement of the particle size distribution and concentration of superfine particles with high density in high concentration suspensions by use of ultrasonic wave.
