| 摘 要： | 分析了弦音计实验在精确度及操作性上存在的不足,对实验做了以下改进:将水平仪的水准器直接安装在弦音计的杠杆中,将接收线圈放在适当位置,利用单片机直接读取共振频率.通过改进实验精确度更高,操作更快捷.

| Abstract: | Through the analysis of the deficiency in the experiment of string vibration,the experiment was improved.For example,the water level gauge was set up on the lever of the sonometer,the receiving coil was properly placed and the resonance frequency was recorded by single chip processor.The accuracy and operability of the improved experiment were increased. |
