摘要
通过对多种振源情形下的方形薄板二维驻波图形(克拉尼图形)的观测与研究,得到不同频率下驻波图形的波节数n+1,m+1及波矢k,从而导出波速(相速)u.实验结果与理论解析解(严格解)相比较符合得很好.
2-dimensional standing waves in square plates （Chladni figures） in several cases was studied both experimentally and theoretically .Wave nodes and wave vector of the standing wave fig-ures were gotten at different frequency ,and the wave velocity was deduced .The results of the experi-ment agreed well to the analytic solutions of theory .
