我们的祖先不仅在光学和力学方面,而且在声学方面,有着辉煌的贡献。关于共鸣现象远在一千五百多年以前的著作中就有所记载了。在南北朝时宋人刘敬叔(公元390-470年)所著的“异苑”中就有这样的记述:“魏时,殿前大钟无故大鸣,人皆异之,以问张华,华曰:‘此蜀郡铜山崩,故钟鸣应之耳。’寻蜀郡,上其事,果如华言。”这里提到的张华(232-300)是晋人,博学洽闻,能识异物,著有“博物志”一书。这件事可能是刘敬叔假托张华之言,但至少可以看出,刘敬叔是明白共鸣现象的存在的。关于共鸣现象的形成原因和防止方法,在
Our ancestors have made brilliant contributions not only in optics and mechanics, but also in acoustics. The phenomenon of resonance is well documented in more than 1500 years. During the Northern and Southern Dynasties, the Song Dynasty emperor Liu Jing (AD 390-470) wrote in the “Different Court”: “When the Wei was beaten, Said: ’This Shujun copper landslides, so the bell should be the ear.’ Find Shujun, on the matter, if the Chinese as saying. ’Zhang Hua mentioned here (232-300) is the Jin, erudite, can Identify foreign objects, author of ”Museum of history" a book. This incident may be made by Liu Jingshu on the assumption of Zhang Hua, but at least it can be seen that Liu Jingshu understands the existence of the resonance phenomenon. On the formation of resonance causes and prevention methods
