The quantum reduced entropy evolution of a V-type three-level atom interacting with the two - mode odd-even entangled coherent field is investigated.

运用量子约化熵研究了V型三能级原子与双模奇偶纠缠相干光场相互作用系统中场熵的演化特性。

It is always to be used to analyze the maximal entangled states as one writes the explicit form of the entropy.

研究一个体系时分析它的纠缠度，讨论最大纠缠态出现的条件也是很有必要的。
