相对论大地测量中偏差方程的业务意义
Operational significance of the deviation equation in relativistic geodesy
摘要：
偏差方程：4向量的二阶微分方程，它测量时空流形中相邻世界线上参考点之间的距离。相对论大地测量：在爱因斯坦引力理论（广义相对论）的框架内，利用微分几何方法在四维弯曲时空中描述地球（或任何行星）的科学，包括对地球引力场的测量。
英文摘要：
Deviation equation: Second order differential equation for the 4-vector which measures the distance between reference points on neighboring world lines in spacetime manifolds. Relativistic geodesy: Science representing the Earth (or any planet), including the measurement of its gravitational field, in a four-dimensional curved spacetime using differential-geometric methods in the framework of Einstein's theory of gravitation (General Relativity).
