摘　　要：定义q变形相干态的Mandel Q参数,导出q变形Mandel Q参数和q变形二阶相关函数的关系,证明在q变形的情况下,单模光场的亚泊松特性与反聚束效应不是等价的,并对增光子k玻色子q相干态的亚泊松特性进行数值研究,结果表明亚泊松特性明显依赖于光子增加数目m.This paper defines the Mandel Q-parameter of the q-deformed coherent state, and deduces the relation between the q-deformed Mandel Q-parameter and the q-deformed second-order correlation function. It proves that both the sub-Poissonian character and the antibunching effect in the q-deformed coherent state are not equivalent. The suh-Poissonian character of the photon-added k-boson q-coherent state is numerically studied. The result indicates that the sub-Poissonian character is evidently dependent on increased number m of photons.
