摘要
本文利用推广的Ｊ－Ｃ模型研究了双光子跃迁过程中原子的质心运动和Ｓｔａｒｋ效应对非均匀场场熵演化的影响。研究结果表明：原子的质心运动通过多普勒效应将破坏场熵演化的周期性，此时场熵演化具有准周期性。Ｓｔａｒｋ效应使场熵演化的准周期缩短。
Effect of moving mass-center and Stark shift on evolution of field entropy is studiedthrough the generalization of J-C model. Our study shows that the moving mass-centercan make the period of evolution of field entropy change.The period of the entropy isshorter than that in which the Stark shift is absent.
