山西地震台网震级偏差与震中距关系的讨论

统计分析了山西省地震台网观测报告测震震级的现状。发现单台震级偏离台网平均震级较大，讨论了这些值偏大的原因，指出这是原始量规函数的地区差异及系统偏差所致，提出求算适合山西地区高精度量规函数的建议

Relationship between Magnitude Deviation and Epicentral Distance of Seismological Network in Shanxi

Statistical analysis was made on the present situation of the magnitude determination of the observation report of Shanxi seismological network,it was discovered that the deviation between the single station magnitude and the average magnitude was bigger.The paper discussed the reason of the bigger deviation,and suggested that it resulted from the region difference of the original calibration function and the systematic deviation.The proposal of solving for high precision calibration function suitable to Shanxi was put forward.
