摘要
利用快速Ｆｏｕｒｉｅｒ变换算法计算Ｌｏｖｅ型槽波理论地震图，对设定的数学模型进行理论合成。研究表明，快速Ｆｏｕｒｉｅｒ变换算法能很好地解决较大炮检距的槽波理论合成，合成记录不仅能全面反映槽波的频散特性，而且能清晰地反映波组能量的不同分布。
In this paper,the method and the principle of calculating the theoretical seisograms of Love channel waves are discussed by using Fast Fourier Transform algorithm,and the theoretical synthesis is made for the mathematical models.The study demomstrates that the Fast Fourier Transform algorithm can well solve the theoretical synthesis of channel waves with longer shot geophone distance,that the synthetic recond not only can show the dispersion properties of channel waves,but also can clearly reflect the different distrbutions of waves energy.
