Abstract：
It is shown that the possible higher squeezing order of the superposition state β>+eiφ βeiδ> of the generalized coherent states of the q deformed non-harmonic oscillator can be expressed as k≠2π n/δ,with n an integer and δ the phase difference between the two generalized coherent states. When δ=π,the order of squeezing can only be odd,which is just the result of the generalized even and odd coherent states of the q deformed non-harmonic oscillator;when δ takes other values,the squeezing order can be even. These results show that the parameter phase difference δ plays the key role in determining the possible squeezing order.
