摘　　要：实验通过稳态法使用TC-3型固体热导率测定仪[1,9]的测量方法改变来测量海洋大气热导率,结构简单,误差更小,一机多用。通过改变加热铜盘A与散热铜盘B之间的距离,探究距离对大气热导率的影响,并与教材中介绍的气体热导率测定仪测量的大气热导率进行比较。Experiments that steady-state method use the TC-type 3 solid thermal conductivity meter which change the usual method to measure ocean atmospheric thermal conductivity, with simple structure, smaller error,and multi-usage. We can know the effects of distance on the atmospheric thermal conductivity and compare with the introduction of gas in the material thermal conductivity meter measuring by changing the distance between heating copper plate and copper cooling plate B.
