基于迈克尔孙干涉原理的杨氏模量-线胀系数测定综合实验仪
Integrative Experiment Apparatus to Measure Yang′s Modulus and Linear Expansion Coefficient Based on the Principle of Michelson Interference
【摘要】 在迈克耳孙干涉原理的两条干涉光路中,分别设置可以精确测量金属丝的拉伸长度和金属棒热膨胀伸长量的装置,从而设计出一种可以分别测量金属杨氏模量和线胀系数的新型综合实验仪器.实验结果表明,测试精度超过现有的测量方法。
【Abstract】 Based on the principle of Michelson interference a new integrative experiment apparatus to measure linear expansion coefficient and Yang′s modulus of metals is designed and manufactured primarily.The results of experiment indicate that it has better precise than that of traditional method with optical lever.
