摘要
本文提出RG线所对应的空间位置是真正的浮动基准面的概念，论述了水平校正基准面两步法静校正的优点，指出当前在某盆地所采用的“浮动基准面”是一种固定基准面，而不是浮动基准面。在这个基准面上叠加成像，使反射时间（t0）、速度受到歪曲，也给偏移带来严重误差。
This paper presents the concept that the correspoding locus of the RG line is the true floating datum. The advantages of the two-step static correction using leve datum are expounded. It is indicated that the so-called floating datum used in a certain basin is actually a fixed datum, not a floating datum.The stack imaging using the datum results in the distortion of t0 and velocity of reflection wave and bring about serious error for the migration.
