摘要

弦振动实验中，在固定端施加张力不变的前提下，改变弦长度。利用振动频率与驻波波长的关系，得到弦的线密度。通过比较不同弦长下得到的弦的线密度与弦质量长度比结果的比较，讨论了弦长对弦线密度测量结果的影响，分析了弦振动实验中合理选择弦长的必要性。

Abstract:

In the string vibration experiment, the string length is changed on the premise that the tensionapplied at the fixed end is unchanged.Using the relationship between vibration frequency and standing wavewavelength ,the linear density of string is obtained.By comparing the results of string linear density and stringmass length ratio under different chord lengths, the influence of chord length on the measurement results ofstring linear density is discussed ,and the necessity of reasonable selection of chord length in string vibrationexperiment is analyzed.

Key words: string vibration standing wave linear density chord length
