At the same microwave excitation,double-piece-window has bigger critical dissipation power capacity than the single-piece-window.TE11 model electromagnetic
In this paper,the beam-wave interaction of a 170 GHz megawatt-level corrugated coaxial-gyrotron operating at TE31,12 mode was studied numerically.Based on t
碳膜分离技术作为分离过程的一种重要方法,在气体分离上的研究取得了突破性进展。分子筛碳膜的气体分离能力远大于聚合物膜,在耐高温、耐有机溶剂及蒸汽、耐酸碱等性能上均优于聚合物膜,因此与之相关的研究具有广阔的应用前景。本文以聚酰亚胺为原料,在600℃下利用高温裂解方法制备碳膜。通过对一系列小分子气体(如:H2,CH4,CO2,N2)的渗透率测试,并计算碳膜对各气体的理想分离系数。同时考察了碳膜制备过程中
