摘要
利用二滩地震遥测台网１９９７年５～１２月的地震记录资料，对“二滩水电站地震遥测台网持续时间震级的研制”一文中得到的平均持续时间震级公式进行了实际检验。检验结果表明，用平均持续时间确定的震级ＭＤ与用水平地动位移确定的震级ＭＬ相差绝大多数在０１０级以内，这说明了该经验公式符合二滩地震台网的实际。并且该经验公式还为速报限幅地震的震级提供了可靠的依据和方便，在地震速报中具有突出的实用价值。
By using data taken by seismic telemetry network of Ertan from May to December 1997,we made an examine on the suitability of the magnitude formula which come from the paper “Study on estimate of magnitude of local earthquake from signal duration for Ertan Seismic Telemetry Network” Our result shows that the magnitude difference between the formula of continuous mean time and formula of horizontal ground displacement is less than 0 1 So the formula of continuous time magnitude of earthquake is suitable for the seismic telemetry network of Ertan Hydroelectric Station and is also convenient for fast determination of earthquake magnitude.
