摘要
本文报道我们设计热膨胀系数测量实验原理、实验方法及其实验结果。热膨胀系数测量采用直流惠斯登电桥方法，可使用的温度范围为4．2-700K。该实验设计解决了磁性对热膨胀的贡献。
The design of an experiment on the thermal expansion coefficient, including experiment principle and experiment methods and experiment results are reported in the paper. The thermal expansion is measured by the direct current Wheatstone bridge in the temperature ranging from 4. 2-700K. The magnetic contribution to the thermal expansion coefficient is settled.
