| 摘 要： | 采用正则化平滑因子方法,对重力台站连续观测资料进行处理和讨论,尝试分离同震信号。结果表明,该方法可以有效地分离并获取同震重力效应和地震波信号,且估算的同震重力效应与理论模拟有较好的一致性,可为快速反演地震参数及地震预警提供更多的约束条件。

| Abstract: | The regularized smoothing factor method is adopted to process and analyze continuous gravity data and to attempt separate coseismic signals. The results show that this method can effectively separate and obtain the coseismic gravity change and seismic wave and that the estimated co-seismic gravity change has good consistency with the theoretical simulation results, providing more constraint conditions for fast inversion of seismic parameters and early warning. |
