摘　　要：利用q变形玻色产生算符和湮没算符及其逆算符的性质,引入了q变形的两种对相干态,研究了q变形对相干态的反聚束效应和两模间的关联特性.结果表明,q变形对相干态呈现反聚束效应,两模的光子相互关联,并且q参数对这些非经典特性的调节比较明显,随着q偏离1越大,这些特性越明显.Using the properties of the q-deformed boson creation and annihilation operators and their inversed operators, two kind of q-deformed pair coherent states are introduced. Antibunching effects and correlation properties between two modes in the states are investigated. It is shown that q-deformed pair coherent states exhibit antibunching effects and the photons of the two modes are correlated. These nonclassical effects are influenced by the parameter q. These effects increase when |1nq| increases.
