【摘要】 用弦音计做两端固定弦振动实验中出现了和音叉计不同的共振现象,如长春五光的仪器出现了 f0 ∶fk=1n∶1的共振现象,PASCO公司的产品出现了f0∶fk=12n∶1的共振现象,本文分析和解释了这些现象产生的原因,并提出了实验改进方案.更多还原

【Abstract】 The paper shows different resonant phenomena in the experiment of vibration of the string with two fixed ends by using sonometer and turning fork, such as the resonance of f 0∶f k= 1n∶1 for the instrument produced by Changchun No.5 Optical Instrument Co. Ltd., and f 0∶f k= 12n∶1 for PASCO. The reason is analysed for the abnormal resonance, and the improvement scheme is put forward.更多还原
