杨氏弹性模量测量仪的改进

Improvement of the instrument of measuring Young's modulus

测定杨氏弹性模量的实验是大学物理实验课的重要实验之一,通过反复多次的实验探索,对杨氏弹性模量测量仪的关键性组件——光杠杆进行了有效改进从而彻底消除了光杠杆易翻落摔坏的隐患,使更换镜片方便,反射像十分易于寻找,实验效果非常明显.

The Experiment of measuring Young＇s modulus is one of the most important experiments in the course of experiments of university physics. With the guidance of teachers and longtime experimenting, the optical lever-a key component of the instrument of the experiment of measuring young＇s modulus-is improved, which thoroughly eliminates the hidden trouble that the optical lever is easy to drop and break.
