摘要
本文对现行教材中一维无限深势阱内粒子动量概率分布的两种不同结论进行了较深入的讨论，认为ｖｏｎＮｅｕｍａｎｎ公理系统在处理无限深势阱问题时确有困难。最后采用一种新的态空间概念，使上述困难得以解决。
Two results concerning the probability distribution of momentum for a particlein one-dimensional infinite square well appeared in available textbooks are discussed。And itis shown that the axiom system of van Neumann meets difficullies in dealing this problem。Anew concept of state spaee in introduced in order to avoid this difficulties。
