本文基于傅里叶热传导的实验原理，自主设计并开发了一种开放式动态法金属热导率实验测量设备. 通过对实验测量结果与误差进行系统分析，给出了进一步提高实验测量精度的理论改进模型和对应的实验测量方法. 相关实验设备、内容与原理对于大学物理实验教学具有一定借鉴意义，设备不仅可用于物理实验教学与科研实验，还可用于开放条件下的工业测量实践等．

Based on the experimental principle of Fourier thermal conductivity, in this paper an open dynamic metal thermal conductivity experimental measuring device is independently designed and developed. Through systematic analysis of the experimental measurement results and errors, the theoretical improvement model and corresponding experimental measurement methods for further improving the experimental measurement accuracy are given. The relevant experimental equipment, contents and principles have certain reference significance for college physics experiment teaching. The equipment can be used not only for physical experiment teaching and scientific research practice, but also for industrial measurement practice under open conditions.
