摘要：As the kinetically sluggish oxygen evolution reaction(OER)is considered to be a bottleneck in overall water splitting,it is necessary to develop a highly active and stable electrocatalyst to overcome this ***,we successfully fabricated a three-dimensional iron-dysprosium oxide co-regulated in-situ formed MOF-Ni arrays on carbon cloth(FeDy@MOF-Ni/CC)through a facile two-step hydrothermal *** studies demonstrate that the designed FeDy@MOF-Ni/CC catalyst requires an overpotential of only 251 mV to reach 10 mA cm-2 with a small Tafel slope of 52.1 mV ***,the stability declined by only 5.5%after 80 h of continuous testing in 1.0 M ***,a cell voltage of only 1.57 V in the overall water splitting system is sufficient to achieve 10 mA cm-2;this value is far better than that of most previously reported *** excellent catalytic performance originates from the unique 3D rhombus-like structure,as well as coupling synergies of Fe-Dy-Ni *** combination of lanthanide and transition metal species in the synthesis strategy may open entirely new possibilities with promising potential in the design of highly active OER electrocatalysts.

摘要：为解决弹性光网络中多链路故障保护的高保护资源冗余度问题,该文提出一种面向可靠性的多链路故障概率保护与保护资源重配置(ROPP-BR)策略。在ROPP-BR策略中,该文综合考虑频谱资源消耗和链路故障概率,分别设计了工作与保护路径的链路代价函数,以较小代价分别选择业务可靠性高且频谱资源消耗少的备选工作与保护光路。为满足业务差异化的可靠性需求,ROPP-BR策略设计了一种面向可靠性的概率保护机制,建立了业务可靠性评估模型,在满足业务的可靠性需求的限制下灵活地配置概率保护路径。当业务将要被阻塞时,该文提出一种基于极大团的保护光路重配置方法,对网络中的业务保护资源进行重配置,提高保护频隙的共享度。仿真表明,所提策略兼顾了带宽阻塞率与可靠性性能,有效地降低了保护资源冗余度。
