The Magellanic system is one of the nearest galaxies to us and this proximity enables us to observe Interstellar Medium, young stellar objects and so on with highest resolution. It is indeed one of the most crucial targets since molecular clouds are resolved to molecular cloud cores - this is not possible for the other external galaxies yet - with the ground base radio telescopes. In this program, we conducted mm and submm high sensitivity observations to survey the molecular clouds and cloud cores, and derived their structure and physical properties. We also obtained the structure and properties of the interstellar dust from the most recent infrared satellite observations. These new infrared datasets are of important to obtain a new database of the young stellar objects. Careful comparisons of these datasets lead us to obtaine deeper knowledge of the interstellar medium, such as influence of active star formation and/or supergiant shells to the surrounding materials, as well as some existence of CO dark molecular gas.

麦哲伦星系是距离我们最近的星系之一，这种接近使我们能够以最高分辨率观察星际介质、年轻恒星物体等。它确实是最重要的目标之一，因为通过地面射电望远镜将分子云解析为分子云核心——这对于其他外部星系来说是不可能的。在这个项目中，我们进行了毫米和亚毫米高灵敏度观测来调查分子云和云核，并得出它们的结构和物理性质。我们还从最近的红外卫星观测中获得了星际尘埃的结构和性质。这些新的红外数据集对于获得年轻恒星天体的新数据库具有重要意义。对这些数据集的仔细比较使我们能够更深入地了解星际介质，例如活跃恒星形成和/或超巨星壳层对周围材料的影响，以及二氧化碳暗分子气体的存在。
