| 摘 要： | 利用有限维的Ｐ－Ｂ相位算符，定义相位的湮灭和产生算符ψ，ψ＾＋。将此算符与粒子数的湮灭和产生算符ａ，ａ＾＋相比较，由其相似性可引进相应的相位平移算符。将此算符作用在零相位态上得相位相干态，最后讨论此相干态的性质。

| Abstract: | Utilized P-B phase operators of a finite basis set,the creation ( ) and annihilation( +) operators of the phase quanta are defined resl'ectively. Then these operators are comprared with the photou creation (a+) and annihilation (a) operators.From their similar properties,the phase displacement operators are introdnced. Then the phase coherent states are defined.Finally the operator squeezing properties are discussed. |
