摘　　要：运用克尔度规近似地分析了不带电的球对称弱引力源的自转对外部时空所产生的影响.如:质量产生的时空弯曲效应如何受自转的影响;经、纬向测地线长度如何受自转的影响;时空的对称性如何受自转的影响等.In this paper,the effect of the rotation of the unbalanced spherically symmetric weak gravitational source on the external space-time is analyzed by the Kerr metric. Such as how the spatiotemporal bending effect of the gravitational mass is affected by the rotation; how the length of the geodesic is affected by the rotation; how the symmetry of time and space is affected by the rotation.
