摘　　要：本文研究了叠加相干态的Ｗｅｈｒｌ熵和Ｓｈａｎｎｏｎ熵，并讨论了Ｓｈａｎｎｏｎ熵与广义坐标压缩性的关系．结果表明Ｗｅｈｒｌ熵和Ｓｈａｎｎｏｎ熵与叠加参数有关系，且叠加参数对Ｓｈａｎｎｏｎ熵的影响较大．We studied the Wehrl's entropy and Shannon's entropy for superposition coherent states and discussed the relations. It is shown that the entropies are dependent on the superposition coefficient. We point out that the superposition coefficient has great effects on the Shannon's entropy.
