【摘要】 传统的测量杨氏模量的静态拉伸法,操作不方便,误差较大。采用劈尖的等厚干涉法测量金属丝的微小伸长量,能够简化实验过程,并提高实验精度。

【Abstract】 There exists inconvenience and big error when Yong’s Modulus is measured with traditional static tensile method.In this paper,the small elongates is measured by equal thickness interference in wedge-shaped film,and the Yong’s Modulus is calculated.The whole experimental course is simplified.The precision is validated,which shows that the precision is improved by using the method of interference.
