摘　　要：疏散星团是研究恒星形成和演化理论的理想实验室,然而星团的形成模式仍是一个基本但未解决的问题。为了深入探讨星团的形成与演化模式,首先需要从观测上证认出具有物理联系的双星团或星团群系统。开展双星团及星团群性质的研究可以为深入理解恒星等级成团形成的模式提供重要线索;此外,双星团与星团群为研究同一片分子云中星团的形成与演化模式提供了绝佳的机会,并有助于理解星团和母分子云在形态及运动学特性之间的联系。从双星团及星团群的样本甄选和形成机制等出发,简单介绍银河系双星团及星团群的研究历史,着重讨论了Gaia时代该领域的研究近况。Open clusters are ideal laboratories for studying star formation and evolution.However the pattern of the formation of star clusters remains a fundamental and unresolved question.To explore the formation of star clusters,it is essential to search physically con-nected pairs or multiple systems of open clusters that could constrain the theories of star cluster formation.Revealing the properties of binary clusters and cluster groups can also yield important insights into the hierarchical formation of stars.Additionally,binary star clusters and cluster groups provide exceptional opportunities to investigate the formation and evolution patterns of star clusters,which are born in the same molecular cloud and to reveal the connection between the cloud and star clusters in morphological and kinematic properties.This article begins by discussing the selection of samples and the patterns of formation for binary star clusters and cluster groups,providing a concise review of research conducted within the Milky Way,and focusing on recent advancements in thisfield during the Gaia era.
