The offset panel allows correlation of a highamplitudereflection on a near trace with delayed refraction breaks on distant traces thus identifying the hazards.
由 炮检距汇集 图可将近道上的反射高振幅和远道上的折射延迟联系起来，从而确定危险区。

A seismic reflection from that zone will have a highamplitude.
此区的地震反射有高振幅。
3
Reflection signals and high velocity noise change in amplitude and waveform with increasing offset between source and receiver.
