选取格尔木地震台2000年7月到2013年5月的680个地震，与中国地震台网中心提供的《国家台网大震速报目录》进行面波震级的对比，得出格尔木地震台的台基校正值、标准误差；通过计算分析，总结出不同方位、震中距、震级大小的地震震级差异性之间的关系。

Select Golmud Earthquake in July 2000 to May 2013 of 745 Earthquakes, with the China Earthquake Networks Center “National Network earthquake quick report Directory” for the surface wave magnitude comparison drawn Golmud Earthquake the pedestal correction value, standard deviation; through computational analysis , summed up in different directions、epicentraldistance、magnitude differences in the size of the earthquake magnitude between.
