| 摘 要： | 本文在能量守恒、质量守恒、动量守恒、欧姆定律的基础上,提出了一种描述气流中喷口电弧特性的新的物理数学模型—微分-积分模型。由于这一模型既具有积分模型的优点,又具有微分模型的优点,因而较为实用和精确。本文应用这一新型微分-积分电弧模型对SF_6喷口电弧的特性进行了计算,并与一些试验进行了对比。

| Abstract: | Based on energy conservation, mass conservation, momentum conservationand Ohm's law, a new Physical-Mathematical model describing the character-istics of the nozzle arc is built, which is called as Differential-Integral arcmodel. This model has the advantages of differential arc model and that ofintergrated are model, the model is precise and suitable to use. Using the model,the characteristics of SF_6 nozzle arc are caculated in the paper, and the caculatedresults are compared with some experimental results. |
