| Abstract: | Based on the method of phase-parameter inserting and function of software,the modes of single static vibration,which was reconstructed by near-field acoustic holography, were changed to a three-dimension dynamical display. We show the display results of the imitate Chime Stone and the steel disc. It reveals clearly that this method has unique advantage in more meticulous observation and investigation for a complicated vi- bration. |
