  4. It has been shown that whether resonant or non - resonant interaction system, the kerr effect weakens the coupling of the field - atom, shortens the cycle of quantum collapses and revivals of the atomic level occupation and makes the nonclassical correlation properties steady. kerr effects on the properties of the correlation, on the correlation intensity between the two - mode, on the photon - number distribution and on the bunching or antibunching effect of the two - mode su ( 1, 1 ) coherent states produce obviously different characters when it is changed the initial intensity of the light field. that is to say, kerr effect on the two interaction systems is accorded

    數值計算結果表明：無論是共振還是非共振相互作用， kerr效應均使原子與光場的耦合減弱，原子布居的崩塌與復甦的周期縮短，光場的非經典相關的穩定性增強；在初始光場較弱和較強兩種情況下，類kerr介質對雙模su （ 1 ， 1 ）相干態場兩模間的相關性、相關程度以及光子的聚束與反聚束效應產生的作用均有明顯的區別，即kerr效應對系統在共振及非共振作用時的影響是一致的。

  11. The results show that the light field is squeezed regularly, and that the collapse - and - revival of the atomic rabi oscillation appears under the detuning. when the initial squeezed light - field factor r is weak, photon bunching alternates with photon antibunching, and the detuning leads to the reduction of photon antibunching ; to the contrary, the factor r is strong, photon statistical properties are steady bunching, and the detuning makes two - mode correlation properties steady
