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。
Deep well water temperature gradient accurately reflects the size of surface heat flux. In this paper, the relationship between surface heat flux and earthquake prediction is briefly introduced. Then the current status of surface heat flow measurement technology is introduced. Finally, the accuracy of 10 ~ (-5) to 10 ~ (-6) ℃ is reported in detail. ~ (-5) heat flow of optical fiber deep well water temperature gradient sensor theory and experimental research results.
