摘要
介绍了用声速测量仪来测定固体的杨氏模量,并与教材中介绍的动态悬挂法测定固体的杨氏模量进行实验比较,结果更加简单、误差更小,并能一机多用。
This article describes the use of solid velocity measurement instrument to determine the Young's modulus,which compares to the materials described in the determination of dynamic suspend method,the result is easier,the error is smaller,and it can more than one machine.
