摘　　要：采用了激光干涉法测量弹性模量,应用光电传感器检测条纹的明暗交替变化,增加了温度传感器监测环境的温度变化,用注水的方法改变碳钢丝上的拉力,并用压力传感器进行测量,获得了精度较高的测量结果.Elastic modulus was measured by laser interference. In the experiment, the alternate change of light stripe and shade stripe was detected by photoelectric sensor; the change of environ- mental temperature was monitored by temperature sensor. The tension in the carbon steel wire, which changed with the weight of water, was measured by sensor. The measurement results were accurately obtained.

关 键 词：激光干涉 环境温度 弹性模量
