| 摘 要： | 介绍了小波变换的基本原理；利用二阶Ｂ样条函数为小波基，构造了尺度函数和小波函数。通过实际资料证明，小波变换综合考虑了地震信号的时域和频域特征，可获得不同频带的地震剖面，提高地震资料的分辨率。

| Abstract: | In this paper the concept of wavelet transform is introduced and both the scale function and the wavelet function are obtained with the second order B spline function as the wavelet basis.It is tested on actual data that wavelet transform can obtain the seismic profiles of different band and improve the resolution of data after considering the characters of seismic signal in both time domain and frequency domain. |
