Abstract：
In this paper, the quantum statistic properties of the eigenstates of the higher power a_qs^k(k≥3)of the annihilation operator of two-parameter deformed harmonic oscillator are investigated. The results show that the k states have Nth-power squeezing [N=(m+1/2)k,m=0,1,2,…] when k is even,and all of them show the antibunching effect
