摘要
给出了双参数形变量子代数ＳＵ＿（ｑｓ）（２）的相干态的明显形式及其完备性的证明，并据此构造了ＳＵ＿（ｑｓ）（２）的ｑｓ－Ｄｙｓｏｎ实现和ｑｓ－Ｈｏｌｓｔｅｉｎ－Ｐｒｉｍａｋｏｆｆ实现。
The explicit form of the coherent states for a two-paranieter deformed quantum al-gebra SU_(qs)(2) is presented,and their completeness s demonstrated from which the qs-Dyson realiza-tion and qs-Holstein-Primakoff realization for SU_(qs)(2)are constructed.
