Abstract: This paper is to deal with the measurement condition for the QTM meter used in the experiment and its reliability.With the comparison of the experimental data the meter in question,has proved to be the same in its performance as the stable plate thermal conductivity meter,an error within 10% for the isotropic samples and within 5% for the rock sample.

摘要： 本文报道用QTM导热仪测量岩石导热系数的测试条件,并论证测量结果的可靠性。作者将样品用其它QTM导热仪及稳定平板导热仪进行检测,证明对各向同性样品之间的误差<5%,对岩石样品用同类型仪器的测量结果比较测量误差一般在10%以内。
