We proposed a class of the superposition state α|β+beiφ|βeiδ based on the q-deformed generalized coherent states.The higher power squeezing properties of these superposition states are studied.The results show that the power of the squeezing can be expressed as k≠2πn/δ,with n an integer and δ the phase difference between the two generalized coherent states.When δ=π,the power of squeezing can only be odd,when δ takes other values,the squeezing power can be even.These results show that the parameter phase difference δ plays an important role in determining the possible squeezing power,the role of a(b) and β can not be neglected.
