waveguides [17, 18]. LU et al [19] theoretically confirmed that PIT could be realized by studying a waveguide system consisting of MDM bus waveguides coupled with a series of side-coupled cavities and stub... waveguides. HE et al [20] studied the PIT effect and slow light effect of H-shaped MDM waveguide side-coupled with typical bright-dark mode. They proposed a combination of a radiation field model......
]. MCELHINNEY et al [27] divided point clouds into a set of cross-sections. The points in each cross-section were fitted by a 2D cubic spline. Then, the slope of the spline was computed. From the calculated... of the minimal road width. IBRAHIM et al [29] extracted the road curb based on 3D density-based segmentation. A drawback of their method is the difficulty in detecting the curb at the road......

减和电压窗口受限.为了克服这个问题,使用Ni,Mn或Co离子部分取代NaxFeO2中的铁离子形成具有更宽的充放电电压窗口的Nax[FeyM1-y]O2.在众多O3型材料中,Nax[Fe1/2Co1/2]O2显示出更稳定的电位平台和更优异的倍率性能[100].其优异的电化学性能归因于在脱钠过程中发生了O3到P3的相变,形成具有快速离子电导率的P3相.金属离子微量掺杂也可以有效稳定二元/三元金属氧化物...池的放电比容量为120 mA·h/g. 其他同类化合物NaxMFe(CN)6 (M=Co, Ni, Ti, Cu等),如Na2Co3(Fe(CN)6]2和Na2Cu3[Fe(CN)6]2与FeFe-PB结构类似,他们同样拥有两个氧化还原位点(M, Fe),所以作为钠离子电池正极材料具有2个Na+的存储容量,可提升循环寿命和工作电压.从图16(b)可以看出,PBA结构中的铁被钴和镍取代后对其电化学性......
