中国第一批大地热流数据

本文叙述了观测大地热流的方法和仪器, 其中包括在钻孔中测定温度的半导体热敏电阻井温仪和在室内测定岩芯标本热导率的装置.给出了最近几年在华北地区11个地点的16个钻孔中取得的温度和热导率数据以及计算热流值的结果.初步讨论了热流值分布与本区复杂地质条件之间的关系, 如中国北部及东部地区热流值与世界同类型地质单元相比较具有较高值和较大分散性的可能解释. 

THE FIRST PORTION OF DATA OF TERRESTRIAL HEAT FLOW MEASUREMENTS IN CHINA

It is presented here the method and instruments of heat flow measurements in drill holes used in this work, consisting of a sensor of semiconductive thermistor for measuring temperature in drill holes, a laboratory set for determining the thermal conductivity of core samples. Then, the actual data of temperature and thermal conduetivity measurements with the calculated values of heat flow for 16 drill holes at 11 localities obtained during the last few years in North China are given. Some preliminary discussions on the relation of the distribution of heat flow and the complex geological situation in North China are made, for example, on the possible explanation of the higher heat flow values and their more scattering character in northern and eastern China than those of the tectonic regions of similar type in other parts of the world.
