| Abstract: | In this paper,the longitudinal wave effect in the ESPS was investigated. The periodical changing law of oscillation frequency of ESPS varied with the distance between separated electrode and quartz crystal was observed. The influence of the surface conditions of the separated electrode on the longitudinal wave effect was discussed. |
