查询词典 migrators

When applied to image the subsalt dipping faults in the SEG/EAGE salt model and fault blocks/zones in real datasets, the seismic migration by degenerate migrators gives well positioned images for faultrelated complex geological structures.

通过SEG/EAGE盐丘模型和实际地震资料的应用表明，退化Fourier偏移算子能很好地对盐下的陡倾角断层和实际地震剖面上的复杂小断块和大断裂地质构造成像。

Behavior of migration is one rich in social motive and is determined by the personal consciousness of the migrators.

而迁移行动是一种富于社会动机的行为，受迁移者个人意识的控制。

These migrators are almost all about men between 15-35 who are thought to mainly come from the Punjaba area in India through Moscow to England.

这些移民大部分是15到35岁的男性，被认为主要来自印度的Punjab区域，经由莫斯科。

By the time next year's winter migration begins, several summer generations will have lived and died and it will be last year's migrators' great grandchildren that make the trip.

从第二年的冬天繁殖期到来，许多夏天的一代将要出生和死去，并且这也会每年持续产生许多旅行的子孙。

Advancing wavefields by the degenerate migrators is actually a linear interpolation between two splitstep terms in the wavenumber domain.

退化的Fourier偏移算子通过在两个分裂步项之间作波数域线性插值来实现波场延拓，每延拓一层需要比常规的SSF地震偏移方法多一次快速Fourier变换。

With degenerate approximations to the oneway LippmannSchwinger integral equation, we study a category of wideangle degenerate migrators that permit the implementation of seismic migration using fast Fourier transforms alone.

通过对LippmannSchwinger单程波动积分方程的退化核逼近，本文研究了一类宽角退化算子的偏移成像。

Wideangle parabolic approximations to wave equation usually lead to nonconstant differential migrators with their coefficients varying with lateral velocity variations, and hence require a finitedifference numerical implementation.

波动方程宽角抛物逼近得到的通常是非常系数的单程波传播算子，其系数是速度横向变化的函数，因此需要利用有限差分进行数值实施。

The computationally efficient degenerate migrators extend the splitstep Fourier method to steeper propagation angles in largecontrast media at the cost of one more Fourier transform for each extrapolation step.

这种退化偏移算子只用快速Fourier变换进行波场延拓，将常规的Fourier分裂步地震偏移方法推广适应强速度横向变化介质和大角度传播波场。
