摘要
通过分析SN388地震仪所得的地震记录,发现炮点的能量越强,炮点附近的地震道感应越大。通过实验得出结论,炮点附近的感应是由道间串音引起的,采取适当措施就可解决这种问题。
It is discovered by analysis of seismic records from SN 388 seismograph that the more strong energy is at shot point, the more strong induction is among seismic traces near shot point. The conclusion has been got by experiments that the induction near shot point is caused by crosstalk, which can be overcome by suitable measures.
