- Doppler Ground Velocity System 多普勒地速系统
- The outcomes indicate that under the effect of velocity pulse the increment of PGD (peak ground displacement) is greater than that of PGV (peak ground velocity), which has less influence on PGA (peak ground acceleration). 结果表明：在速度脉冲效应下，地震动峰值位移增大值大于峰值速度增大值，而峰值加速度所受影响最小。
