研究了磁阻尼扭摆实验中悬浮纤维的热弹性效应。通过对环境温度的监测和热弹性修正，使振荡周期的不一致性减小了一个数量级。我们还发现，由于噪声的周期增加后的振幅衰减热弹性校正。PACS：04。80.抄送，06。20. Jr
The thermoelastic effect of the suspension fibre in the torsion pendulum experiment with magnetic damping was studied. The disagreement in the oscillation periods was reduced by one order of magnitude through monitoring the ambient temperature and thermoelastic correction. We also found that the period due to noise increases with the amplitude attenuation after thermoelastic correction. PACS: 04. 80. Cc, 06. 20. Jr
