| 摘 要： | 运用弹塑怀理论对眯爆炸震源邻域进行理论分析，导出了水更符合实际的奶缩球腔激发瞬时震源的应力边界条件。在此边界条件下求解波动方程的定解问题，获得了地震子波的解析解，这一理论地震子波罗好地解释了地震勘探中实际观测到的地震子波特性，从而改善了对雷顾子波形成机制的认识。该成本不仅对地震勘探有实用价值，而且对处理其它形成的瞬时震源问题一定的理论意义。

| Abstract: | The theoretical analysis of neighbouring area of point explosive source isachieved by using elasticity-plasticity theory. The analysis brings the reasonablestress boundary condition of the transient source which explodes in ball chamber.The analytic solution of seismic wavelet is known by analysing the determination ofwave equation solution under such boundary condition. The theoretical seismicwavelet clearly indicates the characteristics of real seismic wavelets in seismic ex-ploration to thus improve geophysicists' knowledge of the generation mechanism of Ricker wavelet. The research result is useful to seismic exploration, and has some theoretical significance in coping with other transient source problems, |
