【摘要】：百年前,宇宙线的发现曾极大地开阔了人们对宇观和微观世界的眼界,促成了粒子物理学的诞生.新中国成立之初,早年在国外在此领域业已成果卓著的几位前辈,组织起了中国本土第一支宇宙线研究队伍,在云南乌蒙山中建成了中国第一个宇宙线实验室,十年中收获了一系列高水平的实验成果.不幸,此后近20年的磋跎岁月扩大了中国与日新月异的国际新技术之间的差距,中国的宇宙线研究落到了自我边缘化的境地.幸好国家的改革开放政策为奋起直追提供了机会,中国第二代的宇宙线研究者经过种种摸索,选择了高海拔广延大气簇射观测的路线去实现我国宇宙线研究的复兴.20多年的埋头苦干,在海拔4300m的西藏念青唐古拉山脚下建成了一个现代化、国际化的宇宙线实验基地,完成了中国的宇宙线研究从云雾室、手工化向规模化、信息化的历史性转型,并以其特有的低阈能、高事例率、全天候、宽视场优势和国际合作,开展着多项前沿性的科研项目,迎来了丰收的季节.随着国家的日益富强,中国宇宙线研究的年青一代,必将从更高的起点出发,创造出中国宇宙线研究的更大的辉煌.
[Abstract]:A hundred years ago, the discovery of cosmic rays greatly broadened people's vision of the world of space and microcosm, and led to the birth of particle physics. At the beginning of the founding of New China, several forebears who had already made remarkable achievements in this field abroad in the early years of the founding of New China. Organized the first local cosmic ray research team in China, built China's first cosmic ray laboratory in Wumeng Mountain, Yunnan Province, and gained a series of high-level experimental results in the past ten years. Unfortunately, Since then, the past 20 years have widened the gap between China and the rapidly changing international new technologies, and China's cosmic ray research has fallen into the situation of self-marginalization. Fortunately, the country's reform and opening up policy has provided an opportunity to catch up with each other. The second-generation cosmic ray researchers in China, through various groping, have chosen the high-altitude wide-range atmospheric shower observation route to realize the revival of cosmic ray research in China for more than 20 years. A modernized and internationalized cosmic ray experimental base was built at the foot of Mount Nianqingtang Gula, Tibet, at an altitude of 4300m above sea level, and the historical transformation of China's cosmic ray research from a cloud and fog chamber to a large-scale and information-based cosmic ray research has been completed. With its unique low threshold energy, high case rate, all-weather, wide field of view advantage and international cooperation, many advanced scientific research projects have been carried out, and the harvest season has been ushered in. With the increasing prosperity of the country, the young generation of Chinese cosmic ray research, From a higher starting point, will create a greater brilliance in the study of cosmic rays in China.
