The former is reflection information which has gradually weakened with propagation time caused byattenuationbyabsorption;
前者引起反射波信息随传播时间逐步减弱;
2
The attenuationbyabsorption of seismic waves is closely relative to amplitude information and has higher sensibility if in comparison with other seismic information.
地震波的吸收衰减信息和振幅信息密切相关,与其他地震信息相比具有更高的灵敏度。

But whether it can reach the prospecting aim by study for inversion of attenuationby earth absorption and by decreasing high frequency noise?
