在实验物理学学科中(例如,粒子物理学、光学),详细了解用于研究和探查目标的信号是至关重要的。对地震实验而言,精确确定输入信号在某种程度上还未受到重视。我认为对此问题缺乏兴趣的原因主要有两个: (1)输入信号在穿过地层向下到达目的层的过程中,振幅和频率有很大变化;因此,在输入信号进入地下的沉积岩层之前,了解输入信号是否有用是很值得怀疑的。 (2)人们还不能充分地证明,是否有必要在逐炮的基础上确定定向震源的波形特征。确定性的观点中,我们能够通过下述途径来认识地震数据。首先,在震源信号进入地表下的沉积层之前确定它;然后,加入在波场穿过地层的传播过程中,由于介质参数的变化而引起
In the experimental physics discipline (eg, particle physics, optics), it is crucial to understand the signals used to study and probe the target in detail. For seismic experiments, accurate determination of the input signal has to some degree not been taken seriously. I think there are two main reasons for this lack of interest: (1) The amplitude and frequency of the input signal vary greatly as it passes through the formation down to the target formation; therefore, as the input signal enters the subterranean sedimentary formation Before, knowing if the input signal is useful is questionable. (2) It is still not yet fully demonstrated whether it is necessary to determine the waveform characteristics of a directional source on a gun-by-gun basis. In the case of certainty, we can recognize seismic data in the following ways. First, the source signal is determined before it enters the sedimentary layer below the surface; then, it is added during the propagation of the wave field through the formation as a result of changes in the media parameters
