| 摘 要： | 通过经典极限分析，得知均匀磁场中带电粒子波函数不描述单粒子而描述系综。系综的性质由所取的力学量完全集决定。描述同一系综，矢势采用不同规范的波函数之间仅相差一些规范相因子，规范不变原理成立。

| Abstract: | It was proved that a wavefunction of the charged particle in uniform magnetic fields does not describe a single particle but an ensemble by the method for classical limit. The character of the ensemble depend on the complete set of physical quantity to take. Describing the same ensemble and using the different gauge, the wavefunctions only differ some gauge phase factors, and gauge invariant principle hold. |
