中日两国对撞机建设与运行对比:基于历史和科学计量视角

Comparison of construction and operation of colliders between China and Japan:Based on historical and scientometrics perspectives

从历史发展和运行表现2个角度,对比了中日两国的对撞机工程建设与运行情况。分析表明,建设相对更早的中国对撞机的参数受限于资金、技术等条件,其研究方向为能区较低的粲物理领域;有工程技术基础的日本在确立对撞机建设方向时更具针对性,瞄准了物理前景更为丰富的B物理领域。中日两国对撞机皆取得了重要的科学成果,日本在科研成果产出方面更为突出,国际合作程度更高;中国近年来的成果产出量提升明显,且在粲物理领域的研究方面保持了领先水平。

To compare the colliders between China and Japan from the perspectives of historical development and running performance and to learn the development experience of Japan and provide references for future technological layout,especially for large research infrastructure planning,this study discovers that the parameters of Chinese collider,which was constructed earlier,are limited by funding,technology,and other factors.Its research field is charm physics,whose energy range is lower than that of B physics.Whereas Japan,which has a foundation in engineering technology,targets at the B physics with richer physics prospects.Both colliders have obtained significant scientific achievements.Japan is more prominent in the research output and the degree of international cooperation is higher.The output of Chinese collider has increased significantly in recent years,and China keeps leading in the research of charm physics.
