【摘要】：國際天文聯(lián)合會(IAU)在1991年和2000年分別通過了關(guān)于相對論天文參考系的重要決議。特別是2000年的決議,以兩個互相等價的相對論N體多參考系理論:Brumberg-Kopeikin體系和Damour-Soffel-Xu體系為基礎(chǔ),構(gòu)造了嚴(yán)格且自洽的一階后牛頓(1PN)的局部參考系和全局參考系,并給出了相應(yīng)的坐標(biāo)變換規(guī)則。IAU2000決議發(fā)表后的10多年里,已經(jīng)開始應(yīng)用在一些高精度的天體測量數(shù)據(jù)處理模型中,但是其工程化應(yīng)用還沒有得到廣泛實現(xiàn),特別是目前為止我國沒有將其應(yīng)用到具體的天文觀測或者空間探測計劃中。因此有必要對IAU的相對論天文參考系理論做一個系統(tǒng)的解讀。首先介紹了IAU在1991年給出的一個簡單的相對論參考系決議;隨后在第3章和第4章詳細(xì)討論了Brumberg-Kopeikin理論和Damour-Soffel-Xu體系;接著,詳細(xì)給出了IAU2000年大會關(guān)于相對論參考系的決議內(nèi)容;最后,討論了IAU2000決議的工程化應(yīng)用、近10多年來的理論發(fā)展以及對未來的展望。
[Abstract]:The International Astronomical Union (IAU) adopted important resolutions on relativistic astronomical reference systems in 1991 and 2000 respectively, especially in 2000, based on two equivalent relativistic N-body multireference systems: Brumberg-Kopeikin system and Damour-Soffel-Xu system. The local and global reference systems of strict and self-consistent first-order post-Newton 's 1PN) are constructed, and the corresponding coordinate transformation rules .IAU2000 are given for more than 10 years after the publication of the corresponding coordinate transformation rules. It has been applied to some high precision astrometric data processing models, but its engineering application has not been widely realized. In particular, China has not applied it to specific astronomical observation or space exploration plans so far. Therefore, it is necessary to make a systematic interpretation of IAU's theory of relativistic astronomical reference system. First of all, it is introduced that IAU gave. A simple relativistic reference system resolution; Then in chapter 3 and chapter 4, the theory of Brumberg-Kopeikin and the system of Damour-Soffel-Xu are discussed in detail. Then, the content of the resolution on relativistic reference system of IAU2000 annual conference is given in detail. Finally, the engineering application of IAU2000 resolution is discussed. The last 10 years of theoretical development and prospects for the future.
