本文利用LabVIEW软件对飞行时间质谱仪进行模拟，实现了利用计算机模拟开展飞行时间质谱相关的虚拟实验.利用LabVIEW开展虚拟实验，有助于学生快速学习和掌握仪器的工作原理，激发学生的学习兴趣，培养学生的创新意识.

 In this work, LabVIEW is utilized to simulate a reflectron time-of-flight (TOF) mass spectrometer, and to conduct virtual experiments to investigate the main factors that affect the resolving power of the spectrometer. Such virtual experiments should be helpful for students to understand the working principles of a TOF mass spectrometer quickly. In addition, it also stimulates students’ interest in learning and cultivates their sense of creativity.
