研究了在弱场极限条件下Reissner-Nordstrom （RN）黑洞的引力透镜效应。得到了偏转角和延时的基本方程，得到了主副像位置和放大倍数的解析表达式。由于净正电荷，图像之间的分离增加，但总放大倍率没有变化。
We study gravitational lensing by a Reissner-Nordstrom (RN) black hole in the weak field limit. We obtain the basic equations for the deflection angle and time delay and find analytical expressions for the positions and amplifications of the primary and secondary images. Due to a net positive charge, the separation between images increases, but no change in the total magnification occurs.
