实验研究了常用载体Ga_2O_3,Na_2CO_3在石墨、氧化锆、八氧化三铀、氧化钍、氧化铍及五氧化二钽等六种基体中的作用规律。实验结果指出,在上述六种基体中,载体对谱线强度的影响(logI/I_0)与该元素的电离电位(V)之间有一定的比例关系。根据实验测到的电弧温度和电离度的数据,分析了载体影响的各种因素;最后我们认为,在分馏法的条件下,需要考虑电场的影响,这时,载体的作用主要是通过弧柱中的温度和电离度的变化,使光谱的激发条件更为有利,这类载体对杂质的蒸发过程影响不大。

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. In this paper the influence of the mixing ratio, mass flow rates and arc current on the voltage of longitudinally blown arcs in LPG-air mixtures with fixed arc lenth has been studied.

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. In this paper the influence of the mixing ratio, mass flow rates and arc current on the voltage of longitudinally blown arcs in LPG-air mixtures with fixed arc lenth has been studied. In experiments it was observed, that the arc voltage in combustible mixtures is almost 3/2 time of that of pure N2 or air under the same conditions, and that for constant current and mass flow rate as equivalence ratio a increased from 0 to 3, the arc voltage rapidly decreased at first, then almost kept unchanged or slightly increased, and finally fall down to a value corresponding to that of pure air. It was also observed, that on the cathod tip may deposit a stable graphite layer, protecting the cathode from further erosion. In theoretical analysis have been proposed the basic equations of a reacting multicomponent two-demensional axisymmetric MHD flow with arc heating, its three-zone simplified model solution and four-zone model solution. Based on the theoretical analysis, it can be concluded, that the S-shaped relationship of U with a is probably the combined effect of transport properties of gas mixtures and endothermic reactions, which raise the - enthalpy of the gas mixtures to a higher value than that of pure air.

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.本文通过实验研究了流量、混气比和电流对这一类固定弧长纵吹弧电压的影响.实验表明:其弧电压约比纯空气高1/3;弧电压随混气成份变化近于s形规律;一定条件下可形成电极的石墨保护层,使阴极长寿.理论分析中给出了二维轴对称反应性电弧的磁流体力学基本方程及分区简化模型的解.由混合气电弧的计算及对反应效果的定性分析可以认为,燃烧产物分解吸热是造成高焓值的原因,而混合气输运性质及反应因素二者的综合作用,可能是形成s形曲线的基本原因.
