摘　　要：为了实现对物质内部微观粒子运动过程的直接可视化,研究人员不断探索具有更高时间与空间分辨率的新实验方法与技术.阿秒电子显微技术结合超短光脉冲与电子脉冲,基于泵浦-探测方案,旨在同时提供阿秒时间分辨率与原子级空间分辨率,从而为深入理解物质微观机理和动力学规律提供关键实验参数和技术手段,进而实现物质宏观属性与微观底层运动的有效融合.阿秒电子显微技术自诞生之日起便成为国际上的研究热点,本文将简要介绍超快电子显微镜、阿秒电子脉冲的产生及阿秒电子显微技术的前沿研究进展.To achieve direct visualization of the dynamic motion of microscopic particles inside matter,researchers are constantly exploring new experimental methods and technologies with higher temporal and spatial resolution.Attosecond electron microscopy combines ultrafast laser pulses and electron pulses,based on a pump-probe scheme,to provide both attosecond temporal resolution and atomic-level spatial resolution simultaneously,thereby providing key experimental parameters and technical methods for in-depth understanding of the microscopic mechanism and dynamics of matter,and achieving a fundamental understanding,manipulation and application of macroscopic physical properties.Attosecond electron microscopy has become an international research hotspot since its inception.In this study,the cutting-edge research progress of ultrafast electron microscopy,the generation of attosecond electron pulses and the attosecond electron microscopy will be briefly introduced.
