杨氏模量微小伸长测量方法的研究

A Method of Measuring Micro-extension on Yang's Modulus

文章介绍了杨氏模量的传统测量方法,提出了运用微小伸长测量即百分表(千分表)的新方法,阐明了此方法的工作原理及测试手段,测量实践表明,百分表法测金属丝的杨氏模量方法简化,实验结果可靠。

In this paper, a trad method of measuring Yang's modulus was introduced. A new method of measuring microextension(centimeter) on Yang's modulus was put forward. The principle and testing means were elucidated. This measuring process was predigestion. The result of Yang's modulus of wire was trusty.
