摘要：

2008-2009年，INTEGRAL天文台在硬X射线波段对小麦哲伦云和区域进行了深度观测。该仪器的视场允许同时覆盖整个SMC和麦哲伦桥的东端。INTEGRAL总共在SMC中探测到7个源，在麦哲伦桥中探测到5个源;大多数源是以前未知的系统。几个新的源被探测到正在经历明亮的X射线爆发，除了超巨星系统SMC X-1外，所有的源都表现出瞬态行为。它们都被认为是高质量X射线双星（HMXB）系统，其中致密的物体是一颗中子星。

英文摘要：

Deep observations of the Small Magellanic Cloud (SMC) and region were carried out in the hard X-ray band by the INTEGRAL observatory in 2008-2009. The field of view of the instrument permitted simultaneous coverage of the entire SMC and the eastern end of the Magellanic Bridge. In total, INTEGRAL detected seven sources in the SMC and five in the Magellanic Bridge; the majority of the sources were previously unknown systems. Several of the new sources were detected undergoing bright X- ray outbursts and all the sources exhibited transient behaviour except the supergiant system SMC X-1. They are all thought to be High Mass X-ray Binary (HMXB) systems in which the compact object is a neutron star.
