摘要
本文通过简洁的误差分析导出了计算德布罗意波长时应否考虑相对论效应的误差公式,进而提出了一组实用判据。把这一组判据引入物理教学将会带来不少方便。
By the use of the simple error analysis, we derive severa, error formulae, and propose the practical criteria depending on relativistic effect for the calculations of de Broglie wave length. If these criteria are introduced into physics course, it is beneficial to the teacher and students
