把奇偶相干态推广到了非简谐振子的势场中，发现随着平均能量的增加，奇偶广义相干态交替出现压缩现象．在随时间的演化过程中，自然坐标与自然动量的量子起伏产生周期为π／２的压缩In this paper,the conception of even and odd coherent states is generalized to the nonharmonic oscillator potential. It is found that squeezing exists alternatively in the even and odd coherent states with the increase of the mean energy, and the squeezing of the quantum fluctuation of the natural coordinate in the time evolution has a period of π／２.
