  • Online:2016-04-20 Published:2016-04-20

摘要: 设计了一种夹角能变化的劈尖干涉装置,精确的测量了金属丝的微小伸长量,从而计算出该金属丝的杨氏模量.

关键词: 杨氏模量, 劈尖干涉, 干涉条纹宽度, 金属丝

Abstract: A wedge interference device is designed and its wedge- angle can be changed freely. The mini- elongation of the metal wire can be measured precisely by the device,so that the Young's modulus for steel can be obtained.

Key words: Young's modulus, wedge interference, width of interference fringe, metal wire
