摘要：

An experimental study of the removal of micron particles from flat surfaces by focused ultrasonic waves has been carried out. The response of particles to acoustic forcing at gigahertz frequencies was studied by observation of manipulation and removal of individual particles, and by analytical and computational modeling of the mean acoustic removal forces. Consistencies between experiment and theory imply that secondary acoustic forces of importance in contributing to a mechanism for removal, which is of the correct order to overcome surface-attractive forces on micron particles. © 1994 Academic Press Limited.
