摘要
利用ＳＵ（１，１）_（ｑ，ｓ）量子代数的两参数变形振子构造出归一化的ＳＵ（１，１）_（ｑ，ｓ）相干态，证明了ＳＵ（１，１）_（ｑ，ｓ）量子代数的表示基是正交的，并讨论了它的相干态的归一性和完备性。指出（ＳＵ（１，１）_（ｑ，ｓ）相干态的相干性受参数ｑ、ｓ的影响。
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.
