国际天文联合会(IAU)在1991年和2000年分别通过了关于相对论天文参考系的重要决议。特别是2000年的决议，以两个互相等价的相对论N 体多参考系理论：Brumberg-Kopeikin体系和Damour-Soffel-Xu体系为基础，构造了严格且自洽的一阶后牛顿(1PN)的局部参考系和全局参考系，并给出了相应的坐标变换规则。IAU2000决议发表后的10多年里，已经开始应用在一些高精度的天体测量数据处理模型中，但是其工程化应用还没有得到广泛实现，特别是目前为止我国没有将其应用到具体的天文观测或者空间探测计划中。因此有必要对IAU 的相对论天文参考系理论做一个系统的解读。首先介绍了IAU在1991年给出的一个简单的相对论参考系决议；随后在第3章和第4章详细讨论了Brumberg-Kopeikin理论和Damour-Soffel-Xu体系；接着，详细给出了IAU2000年大会关于相对论参考系的决议内容；最后，讨论了IAU2000决议的工程化应用、近10多年来的理论发展以及对未来的展望。

The International Astronomical Union (IAU) released two important resolutions about the relativistic astronomical reference systems at the year 1991 and 2000 respectively. Especially the resolutions in the year 2000, based on two equivalent theories of multi-reference systems of relativistic N-body system: Brumberg-Kopeikin formalism and Damour-Soffel-Xu formalism, the resolutions constructed theoretically rigorous and consistent local reference system and global reference system with first order post-Newtonian (1PN) level, and gave out the coordinate-transformation rules between the two reference systems. During the more than ten years after the publication of the IAU2000 resolutions, it has begun to be used in some data-processing models of the highly accurate astrometry. But the engineerization of the IAU2000 resolutions is still not widely implemented, especially, there is almost no application of the resolutions to astronomical observations and space explorations in China. Therefore, it is necessary to introduce the IAU’s relativistic theory of astronomical references in details. Firstly we introduce the simple resolutions on relativistic reference systems given by IAU in 1991;And the Brumberg-Kopeikin and Damour-Soffel-Xu formalisms are discussed in detail in the chapter 3 and 4; Then, we give out the details of the IAU2000 resolutions about the relativistic reference-system theory. Finally, we try to give some discussions of the engineerization of the IAU2000 resolutions, theoretical progress of the relativistic reference systems in the recent ten years, and prospects for the future.
