摘　　要：空间微波部件的微放电效应是影响航天器微波传输系统独特的瓶颈问题之一。以星载微波部件微放电阈值仿真中广泛使用的Furman模型为研究对象,以平行平板传输线为例,研究并获得了Furman模型中本征二次电子、弹性散射电子和非弹性散射电子共3类电子的二次电子能谱参量对微放电阈值的影响规律,并通过对二次电子发射系数的影响合理解释了微放电阈值的变化规律,为星载微波部件微放电阈值的精确仿真提供了规律指导。The multipactor effect of space microwave components is one of the unique bottleneck problems affecting the microwave transmission system of spacecraft.Based on parallel flat transmission lines and the Fur-man model which is widely used in multipactor threshold simulation,the influence of secondary electron energy spectrum parameters of intrinsic secondary electrons,elastic scattering electrons,and inelastic scattering electrons in the Furman model on the multipactor threshold is studied,and the change rule of multipactor threshold with parameters are explained reasonably.The research provides guidance for the accurate simulation of multipactor threshold of satellite-borne microwave components.
