摘　　要：针对采用综合平面图法设计的三维束状观测系统成果中满覆盖次数边界与绿山(MESA)软件设计结果存在差别的问题,从面元及覆盖次数的概念出发,将面元细分为纵向面元尺寸和横向面元尺寸,通过对纵向观测系统和横向观测系统具体分析,指出上述两种设计手段存在差别的原因,找出了对综合平面图法设计成果中满覆盖次数边界进行修正的方法。In order to explain the disparity in the results of full coverage boundary between 3-D seismic fasciculate survey system designed by comprehensive plan act and professional design software of MESA Expert, the paper discusses the specific steps as follow: Firstly, the bin is carefully separated into longitudinal bin size and transverse bin size in accordance with the concepts of bin and coverage number; Secondly, the reasons of the disparity be-tween two kinds of designing methods are worked out through the specific analysis of longitudinal survey system and transverse survey system; Finally, full coverage boundary results designed by comprehensive plan act are adopted. What’s more, the paper revises and makes the results as exact full coverage boundary.
