摘要
通过对钡钨阴极流体钡的动量、热量、质量等供应机制理论分析,研究了流体钡在钡钨阴极中的供应机制.结果表明阴极多孔介质内流体钡的供应(动量、热量、质量)等机制主要取决于多孔钨材料的结构、物理性质和流体钡的特性,从而进一步加深对阴极发射机理与寿命的研究.
According to the theoretical analysis in Momentum, Thermal and Mass, the problem of supply mechanism（Momentum;Thermal;Mass） of Barium in the barium-tungsten cathode was dealt with. Results show that the supply mechanism mainly depends on the structure, physical performances of the porous medium and the characteristics of Barium. The research helps us to deeply realize the emitted mechanism of cathode.
