摘　　要：通过研究松辽盆地第四系对地震反射波的吸收过程，得出了影响高频信号采集的主要障碍是第四系表层吸收。因此，高分辨率地震采集必须躲过这个层位，采集频率才能大幅度提高。By means of study the absonbent procession of reflective seismic wave in the Quatennary System in Songliao Basion. We find out the main suspection that influnces the collection of high-frequency signs is the surface absorption of the Quaternary System. As a result, we recomment that to surpass this layer while collecting high-resolution earthquake is necessary. So the limits of sanpling frequeney can be improved at a high level.
