It has been shown that : the little indentation which represents the quantum noise of the system appears in the evolution curves ; the quantum noise which is caused by virtual photon field gradually becomes weak when w increases, the quantum noise increases when n increases ; the virtual photon process make the antibunching effect strengthen, make the squeezing degree deepen obviously, and lead to the additional vibration of entropy, the oscillation extent of the additional vibration of entropy increases when n increases and decreases when co or g increase. besides, the quantum dynamics of two coupling atoms interacting with a single mode ligh t field in a kerr medium is studied in this paper ; the influences of the kerr effect on the mean photon number, the degree of second order coherence of field, the evolution of the field entropy and the squeezing effect are also discussed
）的增大，量子噪聲分別減小和增大；虛光子過程使光場的反聚束效應增強，使光場的壓縮程度明顯加深，並引起了附加的「熵振蕩」 ，這種附加「熵振蕩」的幅度將隨著光場初始平均光子數（ ? ）的增加而增大，隨著光場頻率和原子間耦合系數g的增大而減小。本文還研究了充滿kerr介質腔中「耦合雙原子-單模光場」相互作用系統的量子動力學性質，研究了克爾效應對場的平均光子數、二階相干度、場熵演化特性及光場壓縮效應的影響。 -

摘要本文從光折變晶體中能得出暗孤子所滿足的演化方程出發，用粒子分析力法得出了兩暗孤子相互作用時，其質心間的距離所滿足的演化方程，並得出了兩暗孤子相互作用勢函數的表達式，得到其數值解，並得出如下結論：當兩暗孤子間距離= 0時，其相互作用勢函數有最小值，表示在光折變晶體中有穩定的暗孤子對，並且相互作用達到最大；當兩暗孤子距離5時，其相互作用勢函數幾乎為零，表示兩暗孤子間相互作用很弱，幾乎為零。 -
