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。
通過對多種振源情形下的方形薄闆二維駐波圖形(剋拉尼圖形)的觀測與研究,得到不同頻率下駐波圖形的波節數 n+1,m+1及波矢 k ,從而導齣波速(相速)u 。實驗結果與理論解析解(嚴格解)相比較符閤得很好。

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 .
