| 摘 要： | 活动星系核有两类常见外流，相对论性的射电喷流和非相对论性的物质外流，前者主要在射电强的适动星系核中，以非热辐射为特征，非相对论性外流主要通过紫外吸收线观测到，总结了类星体非对论性外流的一些性质及其X射线观测给出了的问题，指出现有的观测表明非相对论性外流引起的质量损失很重要。

| Abstract: | Two type outflows are seen in Active Galactic Nuclei (AGN). Characterizing by their nonthermal radiation, relstivistic radio jets are detected mainly in radio loud AGN, while nonrelativistic outflow is observed through blue-shifted absorption lines in both radio loud and radio quiet AGN. Some new results on the mass outflow in the quasars and Seyfert galaxies from UV and X-ray observations are summarized. These results highlight the importance of mass loss process in broad absorption line quasars. |
