星体自转动力的推导

摘要

This paper uses the classical mechanics to analyze the force of the revolving component star, plainly declaring the root of the star' rotation power. To begin with, analyze the force of the little stars without liquid core, then draw the conclusion that under the action of rotation torque the rotation of little solid stars takes the same time with that of revolution. The conclusion that the lighter side of the moon trends to the earth and the moon has no liquid core is also explored. The application of the characteristics will greatly simplify the control device which synchronous communication satellites point to. Correct the erroneous view that tidal force makes the moon far away. Secondly with analysis of the big star that has liquid core similar to sphere,a presumption is given that the component star's gravity difference and orbital motion make it produce rotation torque. Moreover,it accelerates the rotation of the component star in return. And the rotation acceleration equation is deduced, which showed the reason why nearly all the stars in the universe rotate in the same direction. As the rotation torque increases slightly with increasing radius,a brief on the formation mechanism of eddying motion of the big stars within liquid core is given.%利用经典力学,对做公转运动的子星进行受力分析,揭示了星体自转动力的产生。首先对无液核固态小星体进行受力分析,得出这种固态小星体在自转力矩作用下,最终将使小星体的自转周期与公转周期达到同步运行。并得出月球轻的一面朝向地球的结论。应用该特性,将大大简化同步通信卫星姿态指向的控制装置。纠正了潮汐力将使月球远离的错误观点。其次是对有液核的类似球体的大星体进行分析,得出作用在子星上的引力差和子星的公转运动使子星产生自转力矩,且其力矩使子星加速自转。并推导出自转加速方程。揭示了宇宙诸天体几乎都沿同一方向转动的原因。考虑自转力矩随星体半径增大而略有增加,对有液核大星体内部的涡旋运动的形成机理进行了简要阐述。
