光谱密度 meaning in Chinese
spectral concentration
spectral decomposition
spectral density
Examples
- As a result of that , the exciton wave function , bound - state energies , and optical spectra are obtained as a function of spatial dimensionality by solving the simple hydrogenic schrodinger equation in the fractional - dimensional space . moreover , this model enables one to study excitations continuously from 1 ~ 3 dimension and provide a quantitative measure of the anisotropy of interactions , as viewed from the excitation dynamics
不仅可以通过解类氢原子问题的薛定谔方程求得到激子波函数、束缚能、光谱密度关于维度变量的解析解，而且可以描述1 3维之间任意维度的激子，因为维度量化了各向异性作用力，反映了系统各向异性的程度。 - Chapter 4 : the paraxial propagation of partially coherent beams with the hermite - gaussian mode is investigated . the more generalized and simple expressions of the mean squared width and the beam quality factor of the beam with different mode order are obtained in terms of the cross - spectral density . our re - sults show that the higher order strengthens the variations of the mean beam width and the beam quality factor for partially coherent beams , and the relation between the two parameters of partially coherent beams is independent of the coherence length
第四章：初步探索了部分相干厄米高斯光的傍轴传输，根据交叉光谱密度得到了其不同模阶数的平均光束束宽和光束质量因子更一般的解析表达式，较高的模阶数使得光束展宽得越快，光束质量变差，且这两个光束参量的关系与部分相干厄米高斯光的相干长度无关。
