用热平衡低温等离子体合成氨法和连续实时取样进样质谱技术来探测放电过程中瞬态成分N2 H6 衰变为氨的反应途径和步骤。实验表明 ,在氮氢混合气体放电合成氨的反应过程中 ,N2 H6 中间体是必经的瞬态成分 The thermal equilibrium low-temperature plasma synthesis of ammonia and continuous real-time sampling of sample mass spectrometry were used to detect the reaction pathway and steps of decay of N2H6 to ammonia during discharge. Experiments show that in the reaction of ammonia and hydrogen mixed gas discharge ammonia synthesis, N2H6 intermediate is a necessary transient component
