地震剖面的长度和记录时间可以作为偏移的输入,从而建立起将偏移剖面上可观测到的倾角与反射界面的空间位置联系起来的简单方程式。这种关系对于寻找临界地震倾角的勘探地球物理学家和研究大陆地壳性质的深部地壳地球物理学家都是重要的。人们观测到,在不少的情况下倾角随着深度减小并向着偏移剖面的边缘倾斜,实际资料的例子表明,这种现象可能与输入的规模有关。倾角随深度的进一步减小,那就可能具有地质意义了,通常我们假设射线是直线,以及在垂直入射的情况下反射射线是在炮检对的中点记录到的,第一个假设对能够记录的倾角估计小了,第二个假设则估计大了。上面叙述的问题都是为了在时间域和空间域计算可
The length and recording time of the seismic section can be used as an input to the offset to establish a simple equation that correlates the observable dip in the offset section with the spatial position of the reflective interface. This relationship is important for both prospecting geophysicists looking for critical seismic dip and deep crust geophysicists studying continental crustal properties. It has been observed that in many cases the dip decreases with depth and slopes towards the edge of the offset profile. Examples of actual data suggest that this phenomenon may be related to the size of the input. It may be of geological significance that the dip angle be further reduced with depth, usually assuming that the ray is a straight line and that the reflected ray is recorded at the midpoint of the collation in the case of normal incidence, the first one being able to The recorded dip is estimated to be small, and the second one is estimated to be large. The problems described above are all calculated in the time domain and the spatial domain
