Abstract：
By using the transforming operators, the Q-deformation of the nonharmonic oscillator algebra is obtained. Based on the algebra, the Q-deformation of generalized coherent states are introduced. It is found that these states have the overcompleteness and they are the minimal uncehainty states for the Q-deformed natural operators, and the relative rate of squeezing of the Q-deformation of generalized even coherent state increases with the degree of deformation in the principal squeezing region.
