本文利用信号的横向相关性和信号振幅随炮检距变化的特征，提出一种既能提取有效反射信号同相轴，又能提取零炮检距道信号的方法。

A method for extracting both effective reflection events and zero-offset trace signals is developed using the lateral coherence and the property that signal amplitude changes with offset.

根据子波振幅谱估算最小相位子波已有多种方法，本文对用希尔伯特变换法、同态法、零相位子波法、松弛迭代法等估算的最小相位子波，进行了详细的分析。

Among the methods for estimating the minimum phase wavelet from its amplitude spectrum, methods of Hilbert-transform, of homomorphy, of zero-phase wavelet and of relaxation-iteration are analysed.

在波峰与波谷重合之处，总振幅实际上为零。

Where a trough and crest coincide we get the total amplitude zero.

So again, if we think of a graph of the wave function, we had the wave function is at its highest amplitude when it's lined up with the nucleus, and then as we got further away from the nucleus, the amplitude of the wave function ends up tapering off until it never hits zero exactly, but it goes down very low.

同样，如果我们想象一幅波函数的图，波函数在原子核的位置上,有着最高的振幅，随着与原子核距离变远，波函数振幅逐渐变小直到,它永远不会到零，但它会变得很小。
