摘要
本文通过导出试样振动的偏微分方程,说明了动态法为什么能够测量杨氏模量。简要地对试样表层的氧化作用对实验结论的影响进行了阐述。
By deducing the oscillating partial differential equation of the sample, this paper illuminates the reason why the dynamic method can measure Young＇s modulus. And it simply sets forth the impact of the surface oxygenation on the conclusion of the experiment.
