中文摘要：

自由基生物学与物理学关系密切，没有物理学关于电子的理论和检测技术，就没有自由基生物学今天的辉煌，没有自由基生物学与物理学的结合，也许至今大部分人都还不知道什么是自由基。文章从自由基生物学的发展讨论物理与生物学的关系。

英文摘要：

There is a close relationship between free-radical biology and physics. The great advances in modem free-radical biology would not have occurred if physics had not provided the theory and detection technology for electrons. Without the combination of free-radical biology with physics, many people today might not even know what a free radical is. The relationship between biology and physics is discussed from the viewpoint of the development of free-radical biology.
