摘要
简要介绍了用百分表测钢丝杨氏弹性模量的原理及方法 ,同时阐明了此方法的主要优点 ,并将此法的测量结果与传统测量光杠杆法的结果作了进一步比较 .
A methed of determining Young modulus of elasticity to a metallic cable by a dial gauge is introduced. The advantage of this methed is avoiding the expectation of the unmeasured variable. The precision of the measurement is higher than traditional optical level method.
