The longitudinal ultrasonic wave was irradiated on a specimen surface in water at an angle of 30 deg to generate the surface acoustic wave (SAW) on the surface. The intensity of SAW was measured under different conditions, and it was found that the intensity of SAW decreased during propagating on the specimen surface greatly compared to the ultrasonic wave traveling in the waver. Then two SAWs were propagated on the plate surface in the opposite direction and were overlapped to generate the standing interference wave. Small alumina particles were scattered in a region where the standing interference wave was generated to distribute the particles following the standing wave. However, there was no formation of the sinusoidal distribution of the particles.
