【Abstract】 In this paper,the authors discuss the planar central configuration of thirteen-body problem by using algebra method.The celestial bodys are located at three concentric circles and the centre of the circles, and take a polygon set shape with regular triangles and regular hexagon as well,then they prove that the thirteen-body forms a central configuration if and only if the celestial bodys in the same circle have equal masses.更多还原
