构造了一种由q变形相干态与q变形真空态叠加而成的态,研究了它的振幅平方压缩性质,借助数值计算方法讨论了叠加系数、变形参数对振幅平方压缩特性的影响.

The superposition states, which are composed of q-vacuum state and q-coherent state,are presented, and their amplitude-squared squeezing properties are disscused. The effects of the superposition coefficient and deformed parameter on their amplitude-squared squeezing properties are studied with the aid of numerical calculation.
