| 摘 要： | 从Cohen定义的量子相空间中的分布函数的一般表达式出发,导出了一个依赖于参数γ的满足边缘条件的实分布函数.求出了谐振子基态和第一激发态的分布函数的表达式,并把γ=1时函数的图象和Wigner函数图象作了比较.

| Abstract: | Based on the general expression of distribution function in the quantum phase space defined by Cohen,a real Cohen distribution function is educed,which depends on the parameter and satisfies the marginal conditions.In addition,the expressions of the derived function for ground state and the first excited state of the harmonic oscillator are gained and their pictures with of the distribution function are compared with that of Wigner function. |
