【摘要】 本文对沈阳台1984～1985年地磁短周期扰动事件进行谱分析,认为:1,帕金森矢量转换函数A、B值随周期增大而平稳缓慢地增大,在周期T=120min时有最大值;2,在T=9～350min中T=150min的各参量出现异常1～3个月后,发生了岫岩哨子河M_L=4.0级地震,周期T=75min的各参量出现异常4～9个月后发生了大连老铁山M_L 4.5级地震。更多还原

【Abstract】 By spectrum analysis of geomagnetic short period disturbance recorded at Shenyang station during 1984—1985, We Consider that 1. A and B Value of transfer function of Parkinson vector raise slowly and steadily with increasing period. There is a maximum at T=120min. 2. XiuYan earthquake of M_L=4.0 occured after various parameters display anomaly of 1—3 months at T=150min when T=9—350min, and Dalian Shock of M_L=4.5 Occured after parameters of T=75min show anomaly of 4—9 months.更多还原
