通过分析圆阵阵列流形,提出一种新的圆阵二维谱估计模型,可以直接应用MUSIC算法进行二维DOA估计,从而避免了对圆阵输出信号进行模式激励.应用此模型仿真分析了均匀圆阵和均匀
In this paper we prove that if G is a planar graph with △ = 5 and without 4-cycles or 6-cycles, then G is edge-6-choosable. This consequence together with know
在热阴极微波电子枪的研制中,为设计微波腔链与波导的耦合孔,应用Derun Li等提出的“能量方法”进行模拟计算。使用MAFIA计算微波电子枪第3腔与外回路馈电波导之间的耦合度,
