本文介绍的在小范围内的定向偏移法,是针对克服大范围对称偏移产生的严重的弧线干扰而提出来的。定向偏移的特点是沿测线采用变化的偏移距,这对陡倾构造的偏移处理有着较好的效果。
This paper introduces a small range of the direction of the offset method is to overcome a wide range of symmetrical offset produced by the serious arc interference made. Directional offset is characterized by varying offsets along the line, which has a good effect on the offset processing of steep structures.
