本文简要介绍了时空度规、后牛顿近似、坐标选择、局部惯性系以及原时与坐标时等有关相对论参考系的基本概念，给出了常用时空坐标之间的变换关系。

Conceptions of Relativistic Reference System and Transformations of Spacetime Coordinates

Several basic conceptions, such as the metric of spacetime, the post-Newtonian approximation, and the choice of coordinates, the local inertial System, the proper time and the coordinate time, are introduced of relativistic reference system. The transformations of spacetime coordinates are given for the reference systems which are often used in astronomy and geodesy.
