摘要

摘要本文认为，最近提出的盒中粒子正则配分函数的近似解析表达式是其他作者早先以一种更直接和有效的方式推导出来的。我们还证明了由同一作者推导的有限框内粒子的正则配分函数是不正确的，因为他们忽略了连续谱的贡献。

Comment on "Thermodynamics of a particle in square well potential"

Abstract We argue that the approximate analytical expression for the canonical partition function for a particle in a box proposed recently was derived earlier by other authors in a more straightforward and efficient way. We also show that the canonical partition function for the particle in a finite box derived by the same authors is incorrect because they overlooked the contribution of the continuum spectrum.

期刊介绍： European Journal of Physics is a journal of the European Physical Society and its primary mission is to assist in maintaining and improving the standard of taught physics in universities and other institutes of higher education. Authors submitting articles must indicate the usefulness of their material to physics education and make clear the level of readership (undergraduate or graduate) for which the article is intended. Submissions that omit this information or which, in the publisher''s opinion, do not contribute to the above mission will not be considered for publication. To this end, we welcome articles that provide original insights and aim to enhance learning in one or more areas of physics. They should normally include at least one of the following: Explanations of how contemporary research can inform the understanding of physics at university level: for example, a survey of a research field at a level accessible to students, explaining how it illustrates some general principles. Original insights into the derivation of results. These should be of some general interest, consisting of more than corrections to textbooks. Descriptions of novel laboratory exercises illustrating new techniques of general interest. Those based on relatively inexpensive equipment are especially welcome. Articles of a scholarly or reflective nature that are aimed to be of interest to, and at a level appropriate for, physics students or recent graduates. Descriptions of successful and original student projects, experimental, theoretical or computational. Discussions of the history, philosophy and epistemology of physics, at a level accessible to physics students and teachers. Reports of new developments in physics curricula and the techniques for teaching physics. Physics Education Research reports: articles that provide original experimental and/or theoretical research contributions that directly relate to the teaching and learning of university-level physics.
