摘　　要：选用太原基准地震台2008年至2009年的数字化地震仪面波震级资料,以中国地震台网中心正式报告给出的震级为标准震级,进行了震级偏差统计分析。结果表明,该台的绝大部分震级偏差ΔM≤0.2级,部分地区地震震级偏差较大(超过0.3级)需进行校正。Based on the surface wave magnitude data of digital seismograph of Taiyuan reference Seismological Station from 2008 to 2009 and taken the magnitudes presented by the formal report of earthquake network center of China as standard magnitudes, statistic and analysis of magnitude error is carried out. The result indicates that most magnitude errors △M of the station are less than and equal 0. 2, and earthquake magnitude errors only for partial area are rather great （ greater than 0. 3） and need to be corrected.
