seismic phase
- 地震记录震相清晰，特别是对记录“影区”地震和极远震有独到之处。
Seismic phases are clear, especially for shadow zone earthquakes and the ultra f distant earthquakes. - 测点上某一震相的振幅和周期决定于震源强度以及震源到测点的整个传播过程中介质对震波的影响。
The amplitude and period of a phase at a receiving point depend on source strength and the effect of medium on seismic wave in the propagating from source to the receiving point. - 首次提出了数字化台网对于近震震相自动识别的“波形变化值增长”算法和“无后续震相”判据。
In order to recognize the seismic phases of a regional earthquake automatically, the algorithm of increasing waveform variation value and the criterion of no subsequent phase are put forward firstly.
