1·Electric arcs in combustible gas mixtures, as a high temperature source in combustion and plasma technology, have a great deal of advantages in comparison with those in noble gases.
以燃料和空气混合物为工质的燃烧反应性电弧等离子体在燃烧技术和等离子体技术中都有广泛的应用前景。
2·In the furnace the heat is generated by the arcs formed between the carbon electrodes and the metal charge, and by the resistance of the charge to the electric current.
炉子的热是利用石墨电极和金属炉料之问产生的电弧以及炉料对电流的电阻来取得的。
