应用超声水箱模型考察了简单3D界面构造绕射地震能量所产生的一些复杂现象。我们用室内水箱完成了超声实验室模拟。以铝块模拟了极简单海底地形。地形为平行凹陷,它可模拟与洋中脊平行的峡谷。研究结果表明,海底一次反射的振幅和相位随传播方 The ultrasonic tank model was used to investigate some complex phenomena caused by the seismic energy of diffraction in the simple 3D interface. We performed an ultrasound lab simulation using an indoor tank. Aluminum blocks simulate a very simple submarine topography. The terrain is a parallel depression, which simulates a canyon parallel to the mid-ocean ridge. The results show that the amplitude and phase of a reflection of the seabed with the propagation side
