本文研究了常压下微间隙介质阻挡放电氮氢等离子体合成氨。采用介质层新技术，在狭窄的放电间隙中获得高能电子，同时N-2和H-2分子电离解离，非弹性碰撞后在非平衡等离子体中形成大量自由原子、离子和自由基。最终产物主要为氨，氨的产率达到12500 ppm（1.25%）。实现了常压等离子体合成氨，为无机合成提供了一种新的方法。
The plasma synthesis of ammonia has been studied in nitrogen-hydrogen plasma using a microgap dielectric barrier-discharge at ambient pressure. With the new technology of dielectric layers, the high-energy electrons are obtained in a narrow discharge gap; meanwhile, N-2 and H-2 molecules are ionized and dissociated and a large number of free atoms, ions, and radicals are formed in a nonequilibrium plasma after inelastic collisions. The final product was mainly ammonia, and the yield of ammonia reaches 12500 ppm (1.25%). In this way, plasma synthesis of ammonia at ambient pressure is realized and a new method is provided for inorganic synthesis.
