摘　　要：大学物理实验中,金属杨氏弹性模量的测定方法主要为光杠杆法,但该法存在调节比较困难、读数过程存在视差、成本高等不足.本文设计了一种利用激光管测定金属杨氏模量的简易装置,成本低廉且操作简单,准确度较高.At present, in college physics experiment, the principal method of measuring Young＇ s elastic mod- ulus is on the basis of optical lever. However, the instrument costs a lot, and difficult to adjust, furthermore paral- lax exists in readings. In this paper, using laser, a kind of simple device of measuring Young＇ s elastic modulus is designed. The experiment can be done easily with high measurement accuracy and at low cost.
