摘　　要：广义相对论关于天体轨道的预言依赖于所选取的坐标系。对不同坐标系下围绕银心运动的星体轨道的差异进行了研究,并讨论这些差异对于确定银河系中心黑洞参数的影响。The theoretical predictions of general relativity on the celestial orbits are coordinate dependent.This paper studies the differences of the orbits of the stars rotating around the massive black hole at the galactic center,and discusses their effects on determining the parameters of the black hole.
