摘要
利用玻色产生、湮灭算符实现了ＳＵ_ｑ（１，１）代数，并找到了ＳＵ_ｑ（１，１）代数的生成元的本征态，进一步证明了这些本征态是相干态。
in this paper, the quatum algebra SU_q(1, 1 ) is generated by means of the creation and annihilation operators, and the eigenstates of the SU_q (1, 1 ) are worked out. It is proved that the eigenstates of the SU_q(l, 1 ) are q- coherent states.
