摘要：

We studied the effects of microlensing on X-ray radiation from a relativistic accretion disk around central Black Hole of Active Galactic Nuclei. To analyze the disk emission we used the ray-tracing method considering both Schwarzschild and Kerr metrics. Two types of microlenses were considered: straight fold caustic and microlensing magnification map. We concentrated our attention on studying the correlation between the X-ray continuum and Fe K alpha spectral line due to microlensing. Our results show that enhancements of the Fe K alpha line in three recently observed gravitationally lensed QSOs (MG J0414+0534 QSO 2237+0305, H1413+117) could be interpreted in terms of microlensing, even if an equivalent X-ray continuum amplification is not observed.
