作者于1980年访美期间,通过样品的成组对比测试,将我国自行试制的地热-Ⅰ型岩石热导仪与美国地质调查所西部总部地热实验室的改型分棒仪,进行实验室间的互检,历时近三个月。对比结果,既肯定了地热-Ⅰ型热导仪的总体适用性,同时也揭示了几项误差因子,为我实验室尽快筹建地热-Ⅱ型热导仪提出了改进方向和设计依据。本文简要报道互检结果及对各项误差因子的分析。
During the visit to the United States in 1980, through the group comparative test of samples, the self-trial geothermal-Ⅰ rock thermal conductivity meter in our country and the modified geodetic laboratory of the US Geological Survey Mutual examination, which lasted nearly three months. The results of the comparisons not only affirm the overall applicability of geothermal-Ⅰ thermal conductivity meter, but also reveal several error factors, which put forward the improvement direction and design basis for geothermal-Ⅱ thermal conductivity meter in our laboratory as soon as possible. This article briefly reports the results of mutual tests and analyzes of various error factors.
