摘要
深井水温梯度精确地反映了地表热流量的大小。本文先简述了地表热流量与地震预报的关系,然后介绍了地表热流测量技术的现状,最后详细报告了精度达10^(-5)到10^(-6)℃、一次可测得10^(-5)个热流值的光纤深井水温梯度传感器的理论和实验研究结果。
Groundwater temperature gradient in a deep well precisely reflects heat flow value at that point. The relationship between heat flow measurement and earthquake prediction and the state-of-the-art of the heat flow measurement technology are described briefly. Theoretical and experimental results of an optical fibre sensor for deep well groundwater temper erature gradient measurement, which can measure temperature at the accuracyof of 10^5 to 10^- 6 ℃ and can get 10^5 heat flow values at one measurement, are given in detail.
