摘要
对西宁地温井数字化资料进行了分析,认为数据稳定可靠,无外界干扰因素存在,其变化形态呈现缓慢上升的年变趋势,在汶川8.0级地震前出现明显的下降型异常变化,值得进一步关注。
It is analyzed the digital data of subsurface temperature in Xining seismic station, and thought that the data are stable and reliable, and no interference factors around the station. The curve of the data appears slow rising in yearly trend. But it appears decline curve before Wenchuan Ms8.0 earthquake, which is an important change.
