Abstract：By use of curve fitting and discretigation analyzing the data of two digital thermometer placed in the same depth at Shahe seismostation,we can conclude that the data are reliable, their change trends keep consistent, the temperature difference from each other is only 0.007 5℃,almost constant and really reflect the downhole temperature variation. The article summarizes the concrete operation method for installing two sets of digital thermometers for comparative observation and solving the difficulty of excluding the instrument trouble when appear abnormal data.
