摘要
利用态迭加原理移去相干态中某一光子数态，研究了这种残缺相干态的各种性质，结果显示出真空态和单光子数态对光场相干度、振幅起伏和光子数分布有十分明显而又完全不同的影响，残缺其他光子数态的相干态，在光场性质上的表现非常相似，均随平均光子数的变化作衰减振荡．
A certain photon hate is removed from a coherent state by the state superstition Principle. The various Properties of this kind of incomplete coherent State are studied. The resultS show that the vaccum State and the single-Photon State have great and quite different influences uPOn coherence degree and amplitude flutuation as well as photon diStribution in coherent hate. For other cases, the incomplete coherent anes exhibit very similar light Properties which oscillate attenuately and Synchronously with the variation of average PhOton number.
