摘要
设计了活动双缝干涉装置,精确地测量了金属丝的微小伸长量,从而实现对碳钢杨氏模量的测量.
The key point of measuring the Young modulus of wire by stretching method was how to measure the tiny elongation accurately .Using the self designed movable double slit interference de-vice ,the change in length was accurately measured ,and the Young modulus for carbon steel was cal-culated .
