荷电动态球体外部引力场中的引力效应

Gravitational Effect in the Outside Field of the Charged Sphere Dependent of Time

在动态Ｖａｉｄｙａ－Ｂｏｎｎｅｒ时空背景下讨论了中性试验粒子的引力效应．通过引入局域洛伦兹空间截面，导出了在该场中中性试验粒子的加速度．最后，还讨论了粒子的加速度和ｄｍ／ｄν的关系．

We discuss the gravitational effect in the Vaidya Bonner space time depentent of time.By introducing local lorentz spacial section,we derive the acceleration of a test particle in this field.Finally,the relation between the acceteration of particle and dm/dν is also discussed.
