| 摘 要： | 弦线存在与张力和弹性模量有关的两种固有频率，在一定条件下可使纵振．动达到最强，因而使横振动达到最大，即产生两重共振，非共振谐波也可出现振峰。提出了纵振动应力与应变的关系，介绍了实验测量方法。

| Abstract: | The string has two kinds of natural frequency relating to the tension and Young's modulus.In certain condition,original resonant standing waves may produce resonance again.A relative formula of the vibration stresses and the vibration strains is presented. |
