TWO-PAKAMETER DEFORMED QUANTRM ALGEBRA SU(1,1)q,s COHERENT STATES AND THEIR PROPERTIES
两参数变形量子代数SU（1,1）q,s的相干态及其性质

The normalized SU(1,1)q,s coherent states are constructed by making use of the q,s-deformed oscillators realization of the SU(1,1)q,s quantum algebra.It is shown that the basis functionof the SU(1,1)q,s quantum algebra is orthogonal.The completeness and normalizing properties of theSU(1,1)q,s coherent states are studied.It is pointed out that the coherent property of the SU(1,1)q,s coherent states are affected by q,s parameters.
