        物理学在20世纪取得了巨大的进展,对物质微观结构的认识实现了3次重大的跨越,粒子物理的成就为其顶峰。世纪之交的中国粒子物理学,应当面向世界科学前沿,结合中国的国情,认真制订中国粒子物理的发展战略。在国内充分利用BEPCII进行粲物理精确测量前沿的研究,同时选择有特色的非加速器物理实验,如粒子天体物理实验、宇宙线观测、中微子物理实验等。我们应大力加强国际合作,重点搞好LHC实验,并积极部署大型直线对撞机的国际合作。高能物理研究基地还应当积极为其它学科提供先进手段和大型平台。

        Physics has made great progress in the 20th century as demonstrated in three important leaps regarding the understanding of microscopic structure of matter with the achievement of particle physics reaching its climax. Chinese particle physics at the cross of centuries is to face science frontiers in the world and its development strategy be carefully worked out according to the plan of the development of science and technology of our country and taking into account China’s actual conditions. We shall make the best use of BEPCII for the frontier study on precision measurement of charm physics, while selecting non-accelerator physics with characteristics, such as particle astrophysics experiment, cosmic ray observation, neutrino physics experiment, etc. We should vigorously strengthen international collaboration by doing a better job of the LHC experiment and actively arranging for the international collaboration on the large linear collider. The research center for high energy physics should also provide other disciplines with advanced means and large platforms.
