This paper presents the Cosine algorithm that can best restrain DC component for amplitudeattenuation.
提出一种能很好抑制幅值衰减的直流分量的余弦算法。

Theoretical and practical results indicate that the method can compensate quite desirably the amplitudeattenuation due to spherical divergence and earth absorption.
经过理论试算和实际处理表明，本方法能较好地消除球面发散和大地吸收对振幅的影响。

A discussion is made on the coupling intensity between the compressional and shear waves and the amplitudeattenuation resulting from the inhomogeneity of the medium.
