摘　　要：探索QCD物质相结构和寻找QCD临界点是高能核物理研究的热点之一。三维Ising-QCD理论认为,临界间歇是QCD临界点的特征信号之一,而相对论重离子碰撞实验中间歇的测量是研究QCD相结构的重要实验探针。本工作简要介绍近年来相对论重离子碰撞中间歇的研究进展。在实验方面,主要介绍RHICSTAR实验中金+金的带电强子的间歇测量结果,以及SPS-NA61/SHINE实验中氩+钪的质子的结果;在模型方面,简要介绍混合UrQMD+CMC模型的结果。最后展望了关于间歇的下一阶段研究。One of the frontier research in high-energy nuclear physics is to study the Quantum Chromodynamics(QCD)phase diagram and locate the critical point.According to 3D Ising-QCD theory,critical intermittency is a distinctive feature of the QCD critical point,and thereby the measurement of intermittency can be served as a crucial probe for studying the QCD phase structure.This paper briefly review recent progress of intermittency analysis in relativistic heavy-ion collisions.In experiment,we present the results of charged hadrons in Au+Au collisions from the RHIC-STAR experiment,and proton results in Ar+Sc collisions from the SPS-NA61 experiment.Additionally,the results from the hybird UrQMD+CMC model are also introduced.Finally,we give a outlook for next stage of research.
