几种弦线的弦振动实验对比研究

Comparative Study on String Vibration of Several Strings

选用五种弦线进行了弦线振动实验研究,通过对大量实验数据的拟合,讨论了不同弦线在弦线张力与波长关系、振动频率与波长关系中的影响,得出每种弦线均存在各自的最佳振动频率和最佳张力.考虑到实验中不换弦线情况下,球拍线是最佳选择,也能更简单、更准确指导学生实验研究.

In this paper,five kinds of strings are used to study the string vibration experiment.By fitting the experimental data, the paper discussed various strings about the influence of the relationship between string tension and wavelength and between wavelength and vibration frequency,and obtained the result that each string has the best vibration frequency and the best tension.The racket string is the best choice when the string is not changed in the experiment,and it can be simpler and more accurate to guide students′ experimental research.
