Geodetic effect
- 测地线效应（测地线效应是广义相对论预言下引力场对具有自转角动量的测试质量的影响，导致其自转角动量沿测地线进动。该效应已被美国国家航空航天局的“引力探测器B”卫星观测实验验证）
网络释义英英释义
...航局发射升空的“重力探测器B”（GP-B）卫星，其使命是验证爱因斯坦广义相对论中的两个重要预言：短程线效应（Geodetic effect）即引力体周围时空的扭曲，另一个称为坐标系拖曳效应（Frame-draging effect）即旋转的物体旋转时拖动的时空量。

Geodetic effect
- abstract: The geodetic effect (also known as geodetic precession, de Sitter precession or de Sitter effect) represents the effect of the curvature of spacetime, predicted by general relativity, on a vector carried along with an orbiting body. For example, the vector could be the angular momentum of a gyroscope orbiting the Earth, as carried out by the Gravity Probe B experiment.
