摘要
基于用拉伸法测量金属丝的弹性模量,通过对千分表对传统测微装置进行替换,对实验过程进行了改进,简化了实验装置,节约了实验室空间,同时克服了原实验方法间接测量量多、实验时间长等缺点,使实验操作简单易行。
Based on the measurement of Elastic Modulus by using stretching methods, the experiment was modified by using the dial indicator properly. By introducing dial indicator in the experiment of the measurement of Elastic Modulus, the experimental setup is simplified, the lab space is saved, and the shortcomings, such as too much indirect measurements, too long experiment time are avoided effectively.
