给出了几种用于初至拾取的地震时窗属性特征的算法。经过试算、比较和分析， 指出地震分形特征初至拾取的不足； 提出地震道时窗内能量比属性特征检测地震初至时间的新方法。该方法能快速和准确拾取初至的起跳时间， 抗噪声能力强。合成地震记录试验表明， 当随机噪声达７５％ 时， 仍能准确拾取初至时间。实际地震资料试算显示， 其正确率达９０％ 左右。
Several algorithms for characterizing seismic time windows for first arrival pick-up are given. After tentative calculation, comparison and analysis, the lack of first arrival of seismic fractal features is pointed out. A new method to detect the first arrival time of seismic earthquakes is proposed. The method can quickly and accurately pick up the take-off time of first arrival, and has strong anti-noise ability. Synthetic seismograms show that when the random noise reaches 75%, the first arrival time can still be accurately picked up. The actual seismic data show that the correct rate of about 90%.
