中文摘要：

推广了量子力学中关于对称性的分析，与对称性相关的守恒量相应地推广为含时守恒量；证明了单粒子（包括相对论情况）在静态均匀磁场和含时线性势中运动具有空间平移不变性；求出了波函数的变换关系和相应的含时守恒量．

英文摘要：

A generalized analysis for symmetry in quantum mechanics is presented. The associated conserved quantities are extended to time-dependent ones. It is shown that a single particle （including the relativistic case） moving in a static uniform magnetic field and a time-dependent linear potential possesses space translation invariance. The translated wave function and the time-dependent conserved quantities are obtained.
