Title: 极端天空 - INTEGRAL的七年

Abstract: Seven years of successful observations of the sky have been completed within the INTEGRAL mission, in the transition regime between X-rays and gamma-rays from ~10-8000 keV. Initially-agreed mission goals have been pursued, and both high-resolution images of point sources and high-resolution spectra of nuclear lines have been obtained. New discoveries have been made, such as X-ray emission from embedded binaries, hard emission tails from AXPs and 60Fe radioactivity lines; these stimulated both theoretical and observational studies, and now make INTEGRAL a valuable asset for the astronomical survey of high-energy sources across the sky. This contribution summarizes the situation after seven years of the mission, and concludes the 7-year anniversary workshop "The extreme sky" held in Otranto, Italy, in Oct 2009.

Abstract: 在INTEGRAL任务中，已成功完成了从约10-8000 keV的X射线和伽马射线之间的过渡区域的七年天空观测。 最初商定的任务目标已被追求，并获得了点源的高分辨率图像和核线的高分辨率光谱。 已经做出了新的发现，例如嵌入双星的X射线发射、AXPs的硬发射尾部和60Fe放射性线；这些激发了理论和观测研究，并现在使INTEGRAL成为全天高能源天文学调查的宝贵资产。 本篇贡献总结了任务七年后的情况，并结束了2009年10月在意大利奥特朗托举行的七周年纪念研讨会“The extreme sky”。
