杨氏弹性模量测量仪的改进

摘要

Aiming at the accuracy measuring problem during the experiment of elastic modulus in lab, the elastic modulus measuring apparatus was redesigned. Laser light was used in the measuring process creatively, which bring accuracy and practicability to the measuring result, take qualitative change to the experiment.%针对实验室测量杨氏弹性模量时碰到的测量困难和测量结果不精确的问题，对该仪器进行了改进。将激光应用到实验数据的测量中，激光在测量过程中体现出的精确性和实用性使该实验的测量体验有了质的改变。
