| 中文摘要: |
| 本文简要介绍基于相位参量插值法并利用计算机软件功能,将近场声全息重建出的单帧、静态的振动模式转变为动态三维显示的原理与技术,并给出对模拟编磬及圆盘振模的显示结果,表明其具有对复杂振动进行更细致观察研究的独特优点。 |
| 英文摘要: |
| 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 vibration. |
