| 摘 要： | 地震勘探中，表层中的虚反射界面对地震波的激发有较大影响，但也是确定炸药震源激发深度的重要依据。本文讨论了虚反射对激发地震波频率和能量的影响，指出了测定虚反射界面的最佳手段，论述了定量确定炸药震源距虚反射界面距离的方法。全理地利用虚反射界面可以达到较好的激发效果。

| Abstract: | The ghosting interface on surface has a serious influence on explosion of seismic wave in seismic prospecting,and is an important basis for determining explosive depth of power source.The paper discussed the influence of ghost on explosive frequency and energy of seismic wave,pointed out the optimal method for determining ghosting interface and proposed the method that can quantitatively determine the distance between power source and ghosting interface,which reasonably uses ghosting interface to obtain a good explosive results. |
