| 摘 要： | 利用激光直射法和反射法对传统的杨氏模量测量方法进行实验改进，实验表明：应用这两种方法测量碳钢丝的杨氏模量，所得测量结果与标准值吻合较好．相对于杨氏模量传统测量方法来说，利用激光测量金属丝杨氏模量不仅调节方便，而且直观性强，准确度高．是对现有光杠杆法测量杨氏模量实验的一种补充和完善．

| Abstract: | The laser is used in this paper to improve the conventional measuring method of young's modulus.According to the data of the experiment,the two methods are visualer,more convenience and have higher accuracy compared with conventional measuring method of youngs modulus,and the measuring result accord with the standard value.In conclusion,Simultaneously the experimental design of this article proposed will be of great benefit to the experiment teaching and the design and manufacture of experimental apparatus. |
