pseudogap赝隙
1.The results show that there arepseudogaps in the excitation spectrums.研究结果表明，在激发谱中存在赝隙。
2.Many anomalous phenomena have been found in thepseudogap state of high-TC superconductors, and a close relationship betweenpseudogap state and superconducting state has been proposed, which makes it a focus of interests.高温超导体赝隙态具有许多反常的现象,与高温超导机理之间有密切联系,一直是研究的焦点。
3.The relationship betweenpseudogap and superconducting states of high-T_C superconductors has been a focus of interest for a long time.高温超导体赝隙态与超导态之间的关系一直是研究的焦点。
3)pseudo-gap赝带隙
1.There will be not only one gap in the photonic band structure in the case of incidence along the direction,it is shown that the middle frequency v ofpseudo-gaps including the first gap and the third gap will increase when the filling fraction of the background dielectric medium inside the opal voids ff decreases, and that v will increase when the sintering factor.应用平面波展开法分析了三维反蛋白石结构光子晶体的带隙性质;计算了沿[111]方向入射时其赝带隙(第一、第三赝带)中心频率分别与填隙材料在模板中填充率ff、模板煅烧因子sf的关系曲线:随ff的减小,v增大;随sf的增大,v随之增大,非理想状态下,ff<100%、sf>1,因此较理想态发生蓝移;由此提出了求解平均填充率ffev与平均煅烧因子sfev的计算框图。
