| 摘 要： | 一、引言近来,在地震勘探中应用弹性波动力学特点的可能性愈来愈明显了。所謂动力学特点主要是指波的相位和振幅而言,正問題的解决归結为解决弹性波动力学問題。这方面在过去几年来已經得到了很大的发展,例如苏联学者Γ.И.彼德拉欣及其領导的小組的.

| Abstract: | In view of the difficulty of obtaining exact solutions of the reflected spherical elastic waves at a free plane boundary; this paper derives the zero and first order approximate solutions of this problem by the method of rays. The results obtained are in good accord with thase obtained by the method of steepest descent. |
