摘　　要：为提高地震资料的信噪比(SignalNoiseRatio,SNR),通过对地震模型纹理进行中值滤波实验分析,研究最优中值滤波跨度与波长、道间时差或频率、视速度之间的关系,推导最优跨度的计算公式,并以理论模型和实际数据进行验证,得到较为满意的中值滤波结果.To improve the signal noise ratio （SNR） of seismic data, the relationship between optimum median filter length and wavelength, the time shift between traces or frequency, and the apparent velocity are studied through the median filter experimental analysis on seismic model lamination. The formulation of optimum median filter length, which is deducted and proved by the theoretic model and real data, can achieve satisfied results.
