一、历史回顾为了发展高能物理,我国现在正在建造一台高能加速器,这就是北京正负电子对撞机,简称BEPC。回顾历史,三十一年前,1956年制定的我国科学发展十二年远景规划中规定,建造一台2GeV电子同步加速器作为我国发展高能物理的第一步。1957年在王淦昌领导下, First, historical review In order to develop high-energy physics, China is now building a high-energy accelerator, which is the Beijing positive and negative electron collider, referred to as BEPC. Reviewing history, thirty-one years ago, China’s 12-year long-term plan for scientific development formulated in 1956 stipulated that a 2GeV electron synchrotron should be built as the first step toward developing high-energy physics in our country. Under the leadership of Wang Ganchang in 1957,
