Abstract: In the inversiontithe seismic，solving the problem on a blind deconvohfionis pretty dificult．There are various methods to discuss this problem．such as the method ofthe cumulant moments etc．In this pflper，the problem on a blind deeonvolufion in the seismicis discussed by using the functionai method，by which Likas etal studiedthe problem onthe restoration of an image．A statisticalfunction(i．e．the varianction)，the maximum point of which includes the wavelet and the coeficient sequence of the reflections，is obtained by using the Kullback-Liebler information measure，and the algorithm is devised for computing the the maximum value ofthe variational function.

摘要： 利用Likas等处理图像恢复的变分法来讨论地震记录反演中的盲目反褶积问题．利用Kullback-leibler信息测 度获得一个非常有用的统计函数(即变分函数)，此函数的极值点就含有所要求的子波及反射系数序列，并且拟订 出求此泛数极值点的一套算法．
