negative dispersion meaning in English

负色散

Second , negative dispersion without absorption , which leads to superluminal light propagation , is achievable in the central resonance structure of the dispersion spectrum . the negative dispersion is slightly weakened as the spacings between dressed states increase
其次，在色散光谱的中心区域，呈现出无吸收负色散，这种效应能够导致超光速传播，但它随着修饰态间距增加而减弱。
The equation is also a unified approach to the design of common trible - clad optical fibers . by genetic algorithm , the optimized refractive index profile ( rip ) of dcf is calculated to obtain maximal value of negative dispersion . this rip ensures the propagation of basic mode in dcfs
然后根据色散方程(特征方程) ，用基因法优化色散补偿光纤的负色散，得到了求得最大负色散时的色散补偿光纤的光纤结构，同时保证基模在光纤中的传输。
