在二十世纪微观物理学的早期发展中,德国物理学家杰姆斯·弗朗克(James Franck)的实验研究起了举足轻重的作用。他的科学工作延续了六十多年。他和G·赫兹(Gustav Hertz)合作的关于“电离势”的实验,载在后来的几乎一切有关普通物理学和原子物理学的书籍中——尽管多数书上的叙述都有悖于历史实情。他性情和善,志趣高洁,温文尔雅,无疾言厉色,但在大是大非的问题上却绝不含糊,能为他人之所不敢为,从而他的人格和言行也颇有可供后人学习之处。 In the early development of micro-physics in the twentieth century, the experimental study of German physicist James Franck played a decisive role. His scientific work lasted more than sixty years. His experiments with “Ionophobia” in cooperation with Gustav Hertz appeared in almost all subsequent books on common physics and atomic physics - though most of the narratives in the book are contrary to historical facts . He is a man of good character, noble and noble, gentle and gentle, with no rhetoric. However, he is not ambiguous about what is right or wrong except for others. Therefore, his personality and demeanor are quite suitable for future generations to learn.
