摘　　要：本文讨论了在"用平板稳态法测量不良导体的导热系数"实验中,对实验过程中数字毫伏表显示电动势测量值与相应的时间的关系,利用Excel程序求渐近线,再求其导数以求散热速率的方法。This article discussed the voltage observed value which is showed by the digital milli - voltage table with the corresponding time relations in the ＂flat stable state method measuring the thermal conductivity coefficient of bad conductor＂ experiment,using the Excel program to find asymptotic lines, in order to resolve heat radiation rate with the derivative method.
