摘要
本文用回归方法探讨建立用尾波持续时间τ确定震级的经验公式,以安徽省无线遥测台网的资料为例用lg^aτ和震中距Δ作为自变量,选择较佳形式。本文比较了使用τ的平均值(?)和各台各自持续时间的方法,也考虑了台站的校正值问题,最后提出了适合安徽台网的公式。M_D=0. 573lg^2τ+0. 00025Δ+0.
A magnitude formula of coda duration is proposed using the regression analysis of bivari-
ate τ,Δ,based on data of radio telemetry seismic network of Anhui province.The formula is
written as follows,M_D=0. 573lg^2τ+0. 00025Δ+0. 581+δ_i.Comparing it with the formula
derived from the methods for average duration value (?) and duration of different station,and
considering calibration value of station,it is shown that author's formula appropreciate for the
seismic network of Anhui province.
