摘要
给出一种新的综合极限方法。在这种极限下证明出二维谐振子量子力学不描述单粒子而描述系综。此系综是由Ａ值相同（Ａ为对应力学量完全集的物理量）。
A new comprehensive limit method is given. It is shown that the quantum mechanics for two dimensional harmonic oscillator does not describe a single particle but an ensemble in the limit. The ensemble is formed of the particles which have the same A value (A is a physical quantity corresponding to the complete set of physical quantity) but a different B value (B is a physical quantity conjugate to A).
