摘　　要：欧洲核子研究中心在2012年发现了希格斯玻色子,成为物理学史上一个新里程碑.目前,全球高能物理界正在积极推动下一代高能正负电子对撞机的预研工作,以便对新发现的希格斯玻色子进行精确测量并探索标准模型之外的新物理.本文简要回顾了历史上能量前沿正负电子对撞机的发展历程及其作用,包括历史上第一台正负电子对撞机Ad A的诞生,在Ad A基础上诞生的ACO,VEPP-II,ADONE,以及后来的SPEAR,DORIS,CESR,TRISTAN,再到至今为止最大的环形正负电子对撞机LEP等能量前沿正负电子对撞机;并进一步介绍了目前国际高能物理界正在预研的未来正负电子对撞机的几种设计方案,如ILC,CLIC,TLEP等,其中包括我国自主提出的下一代环型正负电子对撞机CEPC.In 2012, the discovery of a particle matching the Higgs boson at CERN＇s Large Hadron Collider became a very important milestone in high energy physics history. Research and development towards future high-energy electron-positron colliders is actively explored around the world with the purpose of measuring precisely the properties of this unconfirmed Higgs boson and to discover new physics beyond the Standard Model of particle physics. In this paper, we briefly review the history from the past half century of electron-positron colliders at the high-energy frontier, including the first electron-positron collider AdA, as well as the colliders based AdA, such as ACO, VEPP-II, ADONE, and the later colliders SPEAR, DORIS, CESR, TRISTAN etc., and the last and largest electron-positron collider in the world up to now, LEP. Then, the paper reports several proposals for future electron-positron colliders from around the world such as ILC, CLIC TLEP and so on, in particular China＇s entry, the Circular Electron-Positron Collider.
