| Abstract: | 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. |
