摘　　要：以光子消灭算符α的三次幂α~3的三个正交归一本征态为基矢,通过SU_3变换,构造了α~3的各正交归一本征态组,并着重研究了其中两组的非经典效应,发现有些本征态不但具有反聚束效应,而且也具有压缩效应,它们可以从两个不同的侧面来反映光场的非经典性。In this paper, we took three orthonormalized eigenstates of a^3 third power of photon annihiation operator as basic vectors and constracted every orthonormalized eigenstates group of a^3 through SU_3 trasformation. The emphasis is put on study of nonclssicai effects of two groups of them. It is found that some orthonormalized eigenstates have not only antibunehing, but aqueezing effects. They can reflected nonclassical characteristic of light field from two different sides.
