本文讨论了旋转系统周围共线平衡点的稳定性，该旋转系统由两个通过无质量杆刚性连接的质量组成，在向心力超过重力的情况下。发现当重力加速度与向心加速度之比小于0.125时，L1处出现稳定区，而L2和L3处始终不存在稳定区；结果应用于快速旋转的小行星 2000EB14。
This note discusses the stability of collinear equilibrium points around a rotating system composed of two masses rigidly connected by a massless rod in the case, where the centripetal force outweighs the gravitational force. It is found that a stable region appears at L1when the ratio of gravitational to centripetal acceleration is less than 0.125, and that there is always no stable area at L2and L3; the result is applied to the fast rotating Asteroid 2000EB14.
