Introduces the research results Successfully applied examples. The analysis shows that: (1) the introduction of wavelet can improve the resolution of seismic records; (2) τ-p transform can effectively separate, extract and recognize the refracted waves, reflected waves and surface waves in seismic records; (3) Good effect, has a broad application prospects
