摘　　要：分析了电磁场真空态性质,指出在量子电场中讨论真空电磁场的位相是无意义的.对任一量子态｜Ψ＞,我们引入投影算符∧＝｜0＞＜0｜后,电磁场算符是么正的.In tbis paper, the proper'es of vacuum state in quantum electromagnetic field is discussed. It is pointed out that discussing the phase in electromagnetic field that corresponds to the vacuum state has no meanings. For any quantum state ｜Ψ＞ We prove that phase operator in elecmptic field is unitarly by quoting projection operator.

关 键 词：投影算符 位相算行 么正性 电磁场
