共中心点 meaning in Chinese

cmp
common midpoint

When stacking is performed , such amplitude values should be added at various points on the ellipsoid instead of being merely added at the cmp
因此，在叠加时，该振幅值就不是只在共中心点( cmp )上相加，而应该在椭圆面上各个点相加（当然，在不同点上振幅值是变化的）。
Actual seismic data procession shows the efficiency of this method to increase the signal - to - noise ratio of horizontal stacked profile , especially for inaverage signal - to - noise ratio in pre - stack trace assemblage data
实际地震资料处理表明，这种方法能够有效地提高水平叠加剖面的信噪比，尤其对于叠前的共中心点道集资料中信噪比不均衡的情况，效果更好。
A generalized high order screen extrapolator of double square root ( dsr ) equation is derived from the non - stationary phase shift formula of wavefield continuation , thus a new prestack depth migration method in the cmp - offset domain is proposed
在波场延拓方面，从非稳态相移公式出发，推导出广义高阶屏双平方根波场延拓公式，从而得出了一种新的共中心点-炮检距域叠前深度偏移方法。
