我国宋代的伟大科学家沈括,在他所著的“梦溪笔谈”中,详细地记录了当时的工农业生产情况及政治制度,并且发表了他的广博的科学论点。在“梦溪笔谈”中不仅有着丰富的光学、磁学知识,而且也有着丰富的声学知识。沈括对乐律很有研究,这方面在笔谈中占有很多篇幅。卷四第五条说:“予友人家有一琵琶,置之虚室,以管色奏双调,琵琶弦辄有声应之,奏他调则不应,宝之以为异物。殊不知此乃常理。二十八调但有声同者即应,若徧二十八调而不应,则是逸调声也。……偶在二十八调中人见其应,则以为怪,此常理耳。此声学之至要妙处也”。沈括在这一条里说明了共振现象的普遍存 Shen Kuo, the great scientist of Song Dynasty in our country, recorded in detail his industrial and agricultural production and political system in his “Meng Xi Bi Tan Tan” and published his extensive scientific contention. In “Meng Xi Bi Tan Tan” not only has a wealth of optical, magnetic knowledge, but also has a wealth of acoustic knowledge. Shen Kuo on the music is very much studied, which occupies a lot of space in writing. Volume IV, Article 5, said: “To the family, there is a pipa, set the virtual room to tube color double tone, pipa music at any sound, playing his tune should not, the treasure that foreign body.
