摘　　要："非良导体热导率测量"实验是大学物理实验中很重要的一个实验。实验数据的处理比较繁琐且精确度不高。利用Origin软件处理数据中的非线性拟合和切线功能可以既精确又迅速的得出实验结果,并且结果可视化、数据可及时更新。从而提高了该实验在物理教学中的效果。＂Thermal conductivity of Non-good conductor measurement＂ is an important experiment of the university physics experiment. Data processing in this experiment is very important. Dealing with non-linear curve fit, the slope of tangent seeking by using ＂Origin＂ not only a rapid and accurate method free from complex work, but also a simple way with visual results, which can be changed along with the input data. The solutions cultivate the student＇s ability to analyze and solve problems. The teaching level has been greatly improved.
