摘要
本文对传统的音叉和弦线装置驻波实验进行理论分析．得到音叉和弦线的连接点应为波腹的结论．纠正了一些大学物理教科书视为波节的说法．同时，对驻波演示实验装置提出了新的设计．
The author analyse theoretically the standing wave experiment with traditional instrument consisting of tuning fork and thin string.It is found that the point connecting tuning fork and thin string is a belly instead of a node shown in some textbooks.Relevantly,a new instrument of standing wave experiment is designed.
