摘要
在弯曲法测量玻璃板的杨氏模量实验中,利用自制单缝装置将玻璃板的微小形变转化为狭峰的缝宽变化,通过测量衍射条纹的变化得到负载不同时的玻璃板的微小形变,进而得出样品的杨氏模量.
In the experiment of measuring Young modulus of glass plate by bending method,the single-slit device was made,and by using it the micro deformation was transformed into the change of the slit width.The change of the diffraction fringe of the single slit was measured and the Young modulus of glass plate was calculated.
