【摘要】 使用三分向数字地震仪记录的地震资料,进行了SH和P波最大振幅比的反演,求得了震源参数的最小二乘解。本文确定的1981年河北省滦县震群的震源机制解为:走向98°,倾角54°,滑动角—114°;1982年7月云南省剑川地震的震源机制解为:走向199°,倾角40°,滑动角—110°;1982年10月河北省卢龙地震的震源机制解为:第一条断裂,走向270°,倾角65°,滑动角—135°;第二条断裂,走向195°,倾角80°,滑动角—165°。更多还原

【Abstract】 Least squares method is used to invert source parameters from data recorded by a three-component digital seismograph. It is found that the focal mechanism parameters of the September 1981 Luanxian,Hebei,earthquake swarms are: strike 98°,dip 54°,rake-114°; that of the July 1982 Jianchuan,Yunnan,earthquake are: strike 199°,dip 40°,rake -110°; that of the October 1982 Lulong,Hebei,earthquake are: first group,strike 270°,dip 65°,rake -135°; second group,strike 195°,dip 80°,rake -165°更多还原
