摘要：

用全息干涉法对苏州乐器厂制造的扁钟的振动方式进行了研究。发现钟的非圆形状产生了许多成对的方式,其中一对的一个方式的节线在钟的隆起上,另一个方式在那里则是腹线。两个最低方式的频率比值为1.188,接近于小三度(1.189),这部分是由于钟上铸有六条调音槽的结果。

Abstract: The vibrational modes of an almond-shape bell from the Suzhou Musical Instrument Factory were studied using holographic interferometry. The non-circular shape results in mode pairs, one pair member having a mode at the xian or spine of the bell, the other an antinode. The two lowest modes have a frequency ratio of 1188, close to that of a minor third (1.189), due in part to six tuning grooves cast into the bell.
