查询词典 downgoing

An upgoing and downgoing arrangement of transducers in a logging tool, largely to offset spurious changes in reading caused by variations in borehole size or sonde tilt.

指换能器在测井仪器中的上、下配置方式，主要用来补偿由于井眼尺寸变化或探头倾斜所引起的测井读数的不合理变化。

Each component of the tensors representing the reflection and refraction at the interfaces were expressed in the form of upgoing and downgoing wave.

给出了利用上行波和下行波方式表达的界面反射和折射张量函数及其各分量。

The system is coupled by downgoing and upgoing waves, and the commonly used equation of wavefield continuation is only a special case of the coupled system.

通常所用的波场延拓方程就是该耦合方程组的特例。

Because of the ray asymmetry of the downgoing and upgoing waves, the velocity analysis based on the CMP gather cannot be adapted to that of the converted wave.

转换波上、下行波的不对称性，使得常规基于共中心点道集的速度分析不能适用于转换波。

Results of synthetic and field data examples show that, compared with conventional method, separated wavefields using local slopes are clean and amplitudes are maintained. The interference between upgoing and downgoing wavefields can be eliminated better.

模拟和实际资料处理结果表明，该方法与传统方法相比，分离出的上、下行波噪声假象少，振幅保持好，更好地消除了上、下行波的相互影响。

The wavefield is resolved into upgoing and downgoing components.

波场分解成向上行进和向下行进的分量。

The downgoing component represents reflections from the sea surface while the upgoing component represents reflections and refractions from subterranean strata.

向下行进分量代表从海表面的反射，而向上行进分量代表从地下的地层中的反射和折射。

Based on difference between upgoing and downgoing wavefields in vertical seismic profiling data, a new method to separate upgoing and downgoing wavefields using local event slopes attribute is developed.

基于垂直地震剖面资料中上、下行波视速度的差异，利用地震剖面同相轴局部斜率属性参数，提出了一种分离上、下行波场的新方法。

An algorithm for decomposition of multi wave and multi component data into upgoing and downgoing P wave and S wave was derived in frequency wave number domain in this paper. The reflection coefficient versus incident angle was calculated, which can provide foundational data for the AVO inversion of elastic parameters and prediction of fluid factor.

在频率波数域中采用解析法，解出多层条件下海底实测的多分量地震数据分解成上行和下行P波和S波的算法，导出海底各层地震反射系数随入射角变化的递推计算公式，为海底多波多分量AVO弹性参数的反演及流体因子预测提供基础数据。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
