We research the strong gravitational lensing for the quantum-modified Schwarzschild black hole which is derived from quantum Raychaudhuri equation. With the increase of quantum Raychaudhuri equation parameter η , we find that the distance between the black hole and the light passing by it becomes smaller; the deflection angle gets larger; the magnification of relativistic images is more similar; all of the relativistic images move towards the black hole while the images are farther to each other. These results, as we expect, will degenerate to the case of Schwarzschild black hole when η → 0 $\eta \rightarrow 0$ .

量子修正史瓦西黑洞的强引力透镜效应

我们研究了由量子 Raychaudhuri 方程导出的量子修正 Schwarzschild 黑洞的强引力透镜效应。随着量子Raychaudhuri方程参数η的增加，我们发现黑洞与通过它的光的距离变小；偏转角变大；相对论图像的放大倍数更相似；所有的相对论图像都向黑洞移动，而图像彼此相距较远。正如我们所料，当 η → 0 $\eta \rightarrow 0$ 时，这些结果将退化为 Schwarzschild 黑洞的情况。
