摘要
运用刘复刚和王建(2013a)创建的行星会合指数K指代太阳绕太阳系质心运动时,一般情况,行星系质心是和木星位于太阳一侧.当其它3颗大质量行星(或其它7颗行星)和木星分居在太阳两侧,并且这4颗大质量行星(或8颗行星)与太阳近似排成直列的状态时,行星系质心则处在木星相反一侧,这时造成了太阳绕太阳系质心顺时针旋转的假象.本文对这一认识进行了澄清,并通过图示的方法定性地解释了太阳在一个行星系统平均轨道会合周期内角速度的变化特征.相当太阳系质心(C)从太阳本体旋出直到C再次旋进太阳本体这一时段,太阳轨道运动是处在减速期;而当C旋进直到旋出太阳本体这一时段,太阳轨道运动处在加速期.并将其运动特征与太阳轨道角动量的变率进行了对比,这将为揭示太阳活动规律的动力学机制提供了一种可能途径和新的思想方法.
When the planetary synodic index constructed Liu Fugang and Wang Jian（2013a） before is used to describe the orbital motion of the Sun around the mass center of solar system, the planetary system mass center and the Jupiter are generally located at the same side of the Sun. However, when the other three large planets （Saturn, Uranus, and Neptune） or the other seven planets are located at the reverse side relative to the Jupiter, and when the four large planets or the other eight planets are highly coplanar to the Sun, the planetary system mass center and the Jupiter are located at the different sides of the Sun. This easily leads to a false appearance of the Sun＇s clockwise rotation around the solar system mass center. This paper clarified this problem to improve the understanding of the characterization of orbital motion of the Sun. We qualitatively explained the variation characteristics of the angular velocity for the Sun during an average orbital rendezvous period by means of graphic display. In the duration from the solar system mass center （C） leaving the Sun through re-entering the Sun＇s body, the orbital motion of the Sun is in the deceleration phase; in the duration from C entering the Sun＇s body through leaving the Sun, the orbital motion of the Sun is in the acceleration phase. This characterization is comparable to the variation of the solar orbital angular momentum. As a result, this study may provide a feasible alternative and a new methodology to reveal the dynamic mechanics of the orbital motion of the Sun.
