中文摘要：

利用相干态表象下的Wigner算符及有序算符内的积分技术,计算了非简谐振子Klauder-Perelomov相干态Wigner函数的边缘分布及Tomogram函数.借助于数值计算,讨论了此量子态所具有的量子特性和Wigner函数边缘分布的物理意义.

英文摘要：

In our report, Wigner operators under the coherent state and the integration technique within an ordered product of operators were used to calculate the marginal distributions of Wigner functions and Tomogram functions of the Klauder-Perelomov coherent states of the pseudoharmonic oscillator. Based on numerical compu- tation, the quantum properties and the means of their marginal distribution of Wigner functions were discussed.
