我们研究了中性测试粒子在两个带电黑洞引力场中的运动，黑洞的质量和电荷被选择为使得引力吸引力被静电排斥力补偿，这两个黑洞由极端Reissner-Nordstr{o}m双洞度规描述.我们调查的圆形轨道在赤道平面之间的两个黑洞具有相同的质量，以及圆形轨道的情况下，这个对称平面外。我们表明，第一种情况下减少到一个有效的两体问题的行为类似的系统所描述的Reissner-Nordstr{o}m时空。主要的焦点是针对第二种情况下，与赤道平面外的圆形轨道。
We study the motion of neutral test particles in the gravitational field of two charged black holes described by the extreme Reissner-Nordstr{o}m dihole metric where the masses and charges of the black holes are chosen such that the gravitational attraction is compensated by the electrostatic repulsion. We investigate circular orbits in the equatorial plane between the two black holes with equal masses as well as the case of circular orbits outside this symmetry plane. We show that the first case reduces to an effective two-body problem with a behavior similar to a system described by the Reissner-Nordstr{o}m spacetime. The main focus is directed to the second case with circular orbits outside the equatorial plane.
