标题： Recent highlights in the X-ray study of blazars

摘要： 耀变体在最高频率上表现出幅度最大的通量和光谱变化。因此，监测它们在X射线和伽马射线波段的变化是最有效的手段，可以深入了解这些源的强大能量来源。使用最新一代卫星对最亮耀变体的高能观测，已经使得对其行为进行详细研究成为可能，并且极大地提升了我们对耀变体喷流物理的理解。我将回顾一些关于耀变体多波段监测的最新成果，重点介绍使用BeppoSAX完成的X射线观测活动，并描述一些未来从空间探测耀变体的计划，特别是利用INTEGRAL的任务。 显示英文摘要

摘要： Blazars exhibit flux and spectral variations of largest amplitude at the highest frequencies. Therefore, monitoring their variability at X- and gamma-rays is the most effective tool to peer into the mighty powerhouse of these sources. High energy observations of the brightest blazars with the latest generation of satellites have allowed a detailed study of their behavior and have critically improved our understanding of the physics of blazar jets. I will review some of the recent results of blazar multiwavelength monitoring with emphasis on the X-ray campaigns accomplished with BeppoSAX and I will describe some of the future programs for blazar investigation from space, particularly with INTEGRAL.
