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。With the data recorded by computer, the author studies the experiment progress in detail, which includes the development of pore press, strain, strength of the sand, etc. connecting the development of these phenomena with the development of stress path, the author finds new mechanism which can explain the phenomena in the experiment. what is more, according to the dynamic test of the sand, there appears a steady state at the last phase of the development of strain and stress path, in which the strength of the sand is studied because it is an important parameter in evaluating the stability of sand against liquefaction. secondly, the dynamic constitutive relation was studied through the dynamic tri - axial test
