摘　　要：利用 f振子的湮没算符和产生算符的逆算符的性质 ,得到了SU(1,1)李代数的两个双模非厄密实现 ,在此基础上引入了两种非线性孪相干态 。Using the properties of the inverses of annihilation and creation operators of f oscillator, two two mode non Hermitian realization of SU(1,1) Lie algebra is obtained, and on this basis, two nonlinear pair coherent states are introduced, their statistical properties of photon and phase characteristics are discussed.
