摘　　要：构造了激发k玻色子q相干态a+mq z,k ,j〉q(k≥ 3) ,并用数值计算的方法研究了参数m对反聚束效应的影响 .结果表明 :反聚束效应明显受到m的调节 .对于大x(x =z 2 ) ,激发 (即增加光子 )改变了反聚束效应出现的区间 .对于小x ,当j=0时 ,激发使原来强烈的聚束效应变为强烈的反聚束效应 ;当j≠ 0时 。The excited k-boson q-coherent state a +m qz,k,j〉 q is constructed. The m dependence of the antibunching effect is numerically studied. It is shown that the antibunching effect evidently depends on m: For big x(x=z 2), the excitation can change the region where the antibunching effect appears; For small x, when j=0, the excited states exhibit strong antibunching effect but the unexcited states exhibit strong bunching effect; For small x, when j≠0, both the excited states and the unexcited states exhibit strong antibunching effect.
