运用双流体理论,在同时考虑了碳纳米管中低温氢等离子体的电子碰撞吸收和氢离子碰撞吸收的基础上,理论导出了铁催化高压歧化生成的碳纳米管中低温氢等离子体的微波吸收系数公式,数值计算了不同条件下的微波吸收系数.模拟结果表明,铁催化高压歧化生成的碳纳米管中低温氢等离子体对2.45GHz的微波产生强烈吸收.理论结果与实验数据相吻合. Based on the dual-fluid theory, taking into account the electron impact absorption and hydrogen ion collision absorption of low-temperature hydrogen plasma in carbon nanotubes, the microwave absorption of low-temperature hydrogen plasma generated by iron-catalyzed high pressure disproportionation was theoretically derived Coefficient formula and numerical calculation of the microwave absorption coefficient under different conditions.The simulation results show that the low-temperature hydrogen plasma generated by the iron-catalyzed high pressure disproportionation of carbon nanotubes strongly absorbs the 2.45GHz microwave.The theoretical results are in good agreement with the experimental data.
