相干度 meaning in English
degree of coherence
Examples
- The basic concepts of second - order coherence theory in describing wavefields are introduced . these concepts are the cross - spectral density function and spectral degree of coherence in the space - frequency domain , and the mutual coherence function and the complex degree of coherence in the space - time domain
介绍了二阶相关理论中描述光场相干性质的基本概念，包括空间-时间域中的互相关函数、复相干度和空间-频率域中的交叉谱密度函数、光谱相干度。 - The initial atomic state affects obviously on the nonclassical coherence degree between the two mode cavities , while the influence on the atomic population is not evident . and the initial atomic state affects on the second - order coherence degree for each mode , but the effect on the cavity 1 is stronger than that on the cavity 2
原子初态对两模间的非经典相关程度影响明显，对原子布居概率的影响不明显，对光场两模的二阶相干度均有影响，但其对模场2的影响较其对模场1的影响更强。 - 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，量子噪声分别减小和增大；虚光子过程使光场的反聚束效应增强，使光场的压缩程度明显加深，并引起了附加的“熵振荡” ，这种附加“熵振荡”的幅度将随着光场初始平均光子数( ? )的增加而增大，随着光场频率和原子间耦合系数g的增大而减小。本文还研究了充满kerr介质腔中“耦合双原子-单模光场”相互作用系统的量子动力学性质，研究了克尔效应对场的平均光子数、二阶相干度、场熵演化特性及光场压缩效应的影响。 - In this paper , the nonclassical properties of two two - level atoms interacting with a single mode light field is studied by means of the quantum theory without rotating wave approximation ; the influences of the yirtual photon process 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
