【摘要】 本文从空间假频出发，详细阐述了空间假频的定义、对地震资料质量的影响以及避免方法；并从中推导出了测线部署方向和空间假频之间的关系，得出了三维地震勘探野外采集设计中在确定测线部署方向时应遵循的原则。更多还原

【Abstract】 This paper gives detailed description about the definition of spatial aliening, its effects to seismic data and the way to avoid,from which the relations between line orientation and spatial aliening derived. The results of this paper gives the principle for determining ling orientation which should obeyed in 3D planning.更多还原
