论文摘要
此评论的目的是介绍Maiz J. Math提出的扰动方法。物理。 60，012103（2019）以更清晰的方式。我们直接的程序的结果与该作者获得的结果一致，除了我们在获得大约一个案件时获得确切结果的一种情况。除此之外，我们还表明，对于足够深的双孔电势，扰动方法会大大恶化。
The purpose of this comment is to present the perturbation approach proposed by Maiz J. Math. Phys. 60, 012103 (2019) in a clearer way. The results of our straightforward procedure agree with those obtained by that author except for one case in which we obtain the exact result while he obtained an approximate one. In addition to it, we show that for sufficiently deep double-well potentials the perturbation approach deteriorates considerably.
