摘要
根据非平行矩形板电容器测量弹性模量的实验原理,提出了用非平行矩形板电容器测量金属线胀系数,并对实验装置进行了改进,提高了实验的灵敏度,降低了相对非线性误差.
According to the experiment principle of measuring elastic modulus using non-parallel rectangle plank capacitor, the linear expansion coefficient of metal is measured by non-parallel rectangle plank capacitor. The improved instrument reduced the relative nonlinear error and raised the sensitivity of the apparatus.
