1988年建成的北京正负电子对撞机将中国带入国际粒子物理研究领域，在t-charm物理学中处于领先地位。面对国际上这一研究领域的激烈竞争，中国物理学家提出了北京正负电子对撞机的重大升级项目，即BEPCII。BEPCII项目于2004年初开工，2008年顺利竣工，质量优良，并于2009年7月通过国家验收。从那时起，对撞机一直用于高能物理实验和同步辐射应用，在t-charm物理学中保持领先地位。本文简要回顾了北京正负电子对撞机，重点介绍了北京正负电子对撞机II的科学目标、加速器、BESIII探测器和物理结果，以及研究计划和展望。
The Beijing Electron-Positron Collider (BEPC) completed in 1988 has brought China into the field of international particle physics research, taking the leading position in the t-charm physics. Facing to the international keen competition in this research field, Chinese physicists proposed the project of major upgrade for the Beijing Electron-Positron Collider, i.e. BEPCII. Started in early 2004, the BEPCII project was successfully completed in 2008 with excellent quality, and checked and accepted by the state in July 2009. Since then, the collider has operated for high energy physics experiments as well as for synchrotron radiation application, keeping a leading position in the t-charm physics. Briefly reviewing BEPC, this paper emphasizes the scientific goal of BEPCII, its accelerators, the BESIII detector and physics results as well as research plans and prospects.
