Abstract：
In this paper, the superposition of the qs-coherent states is constructed, and its nonclassical properties such as squeezing property, antibunching effect are studied. The effects of the superposition coefficient and deformed parameter q and s variables on these nonclassical properties are discussed by making use of numerical calculation. The relevant results of the even and odd qs-coherent states, as special cases, are contained in more general conclusion of this paper.
