| 摘 要： | 薛定谔相干态被定义为其坐标与动量平均值的演化与经典解相同的量子态。证明谐振子的任何状态都是薛定谔相干态。并计算了它们的不确定度，指出最小不确定度的态正是Ｇｌａｕｂｅｒ相干态，同时证明了对非谐振子一般不存在薛定谔相干态。

| Abstract: | Schrdinger coherent states(SCS) is defined as those states of quantum system in which the expectation values of coordinates and momentum are same as the results of the solutions of the classical counterpart. It is shown any states of harmonic oscillator are SCS. The uncertainty of such states is evaluated. It is proved the minimum uncertainty state is just the Glauber coherent state. In general, SCS do not exist in anharmonic oscillator systems. |
