【摘要】 根据嘉峪关地震台测震数字化记录近3年的资料,对此期间所发生的206例中强地震的震级进行统计,与《中国地震台网观测报告》提供的标准震级进行对比,对其偏差形成的几种因素进行分析,初步得出校正值,有利于提高嘉峪关地震台地震分析及速报质量。更多还原

【Abstract】 The analysis of seismic magnitude is one of the most basic parameters,the magnitude deviation of the size of the direct impact of the usage of data and data reporting quality.According to the digital record data of nearly 3 years at Jiayuguan Seismic Station,206 cases of moderately strong earthquakes are statisticaly analyzed.Comparing with the standard magnitude provided by"China Seismic Network Report",the several factors that cause the deviation are analyzed and the correction value is ppreliminarily obtained.This result is beneficial to improving the seismic analysis and the quality of report at Jiayuguan station.更多还原
