摘要: 将半导体激光器做成激光杠杆,用于拉伸法测定杨氏弹性模量的实验,可以简化实验装置,并提高微小伸长量的放大倍数.

关键词: 激光, 激光杠杆, 杨氏模量

Abstract: If the semiconductor laser is made as laser lever, it can be applied to the experiment of measuring Young's modulus by the pulling method. This can simplify the installation of experiment, and raise the amplification index of the stretched mini-amount

Key words: laser, laser lever, Young's modulus
