normal moveout meaning in Chinese

正常时差

Facing the problem that we always ask ourselves whether the technique and parmeters we use are suitable , we have to consider it in five main processing step , deconvolution , static correction , normal moveout , noise attenuation and migration
根据噪音在处理过程中的不同阶段表现属性不同，处理中采用不同的处理手段或不同的处理参数分阶段对噪音进行衰减。以便做到最大限度压制噪音，而尽可能不损伤有效信号，提高原始资料的信噪比。
In viewing of the characteristics of propagation of 3d converted wave , studies are performed on the processing methods of 3d converted waves , such as horizontal component rotation , calculation of 3d transition point , hyperbolic velocity analysis and nmo ( normal moveout ) correction of 3d converted wave , and non - hyperbolic velocity ratio analysis and nmo correction of 3d converted wave
基于三维转换波传播特点，对三维转换波资料处理方法进行了研究，包括水平分量旋转，三维转换点计算、三维转换波双曲速度分析与动校正、三维转换波非双曲速度比分析与动校正等。
