| 摘 要： | To calculate the deviations between single station magnitudes and average ones by the magnitude residual statistical method, the paper selects 13086 seismic events recorded by the Gansu broadband digital seismic network from January 2009 to December 2012. The frequency distribution and quantitative statistics of the deviations of earthquake magnitude are analyzed. The M L calibration function is modified and a uniform local magnitude system characteristic of the Gansu region, is obtained.
