摘要 星际弥散带(diffuse interstellar bands;DIBs)是源自星际空间的数百条吸收谱线的总称.自20世纪20年代首次发现两条DIBs以来,对DIBs的观测和证认已有80多年的历史.迄今为止,共观测到了300多条DIBs,但没有一条DIB的载体(carrier)被完全证认.DIBs的证认被认为是困扰着天文学家80多年的天体物理学的经典难题之一.我们简要回顾了星际弥散带的观测历史,介绍了银河系和河外星系星际弥散带的一些观测特征、星际紫外消光2175驼峰强度和星际弥散带的相关性、星际弥散带之间的相关性和星际弥散带的分类方法;对星周环境中是否存在弥散吸收带的观测结果也给予了简要的评述;讨论了星际弥散带的载体和起源.
