补充资料：角动量守恒定律
| 角动量守恒定律 conservation of angular momentum,law of 反映不受外力作用或所受诸外力对某定点（或定轴）的合力矩始终等于零的质点和质点系围绕该点（或轴）运动的普遍规律。物理学的普遍定律之一。例如一个在有心力场中运动的质点，始终受到一个通过力心的有心力作用，因有心力对力心的力矩为零，所以根据角动量定理，该质点对力心的角动量守恒。因此，质点轨迹是平面曲线，且质点对力心的矢径在相等的时间内扫过相等的面积。如果把太阳看成力心，行星看成质点，则上述结论就是开普勒行星运动三定律之一。一个不受外力或外界场作用的质点系，其质点之间相互作用的内力服从牛顿第三定律，因而质点系的内力对任一点的主矩为零，从而导出质点系的角动量守恒。如质点系受到的外力系对某一固定轴之矩的代数和为零，则质点系对该轴的角动量守恒。角动量守恒也是微观物理学中的重要基本规律。在基本粒子衰变、碰撞和转变过程中都遵守反映自然界普遍规律的守恒定律，也包括角动量守恒定律。W.泡利于1931 年根据守恒定律推测自由中子衰变时有反中微子产生，1956年后为实验所证实。 |
