The fundamentals of a quasi-relativistic wave equation, whose solutions match the Schrdinger results for slow-moving particles but are also valid when the particle moves at relativistic speeds, are discussed. This quasi-relativistic wave equation is then used for examining some interesting quantum problems where the introduction of relativistic considerations may produce remarkable consequences. We argue in favor of the academic use of this equation, for introducing students to the implications of the special theory of relativity in introductory quantum mechanics courses.

让相对论量子力学变得简单

讨论了准相对论波动方程的基本原理，该方程的解与缓慢移动粒子的薛定谔结果相匹配，但在粒子以相对论速度移动时也有效。然后，这个准相对论波动方程用于检查一些有趣的量子问题，在这些问题中，引入相对论考虑可能会产生显着的后果。我们赞成在学术上使用这个方程，以便在介绍性量子力学课程中向学生介绍狭义相对论的含义。
