中文摘要	The tests in de-ionized water with micro/nano CeO/sub 2/ particles are carried out to study the effect of the micro/nano particles in inception of cavitation erosion. The existence of micro/nano particles is found to be the requisite factor and the degree of cavitation erosion is related to the sizes of the particles. Particles in the micro/nano scale may act as the transporters of micro bubbles to keep or get close to the solid surface together and the pressure fluctuation induced by the surface roughness causes the collapse of bubbles and erosion of the surface. Discrete phase models are employed to simulation the moving tracks of the particles. The sizes of the particles affect their capabilities of keeping and getting close to the surface. The effect of the particles of a certain size in cavitation erosion is determined by the combinational action of the two.
