| 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 conservation
and Ohm's law, a new Physical-Mathematical model describing the character-
istics of the nozzle arc is built, which is called as Differential-Integral arc
model. This model has the advantages of differential arc model and that of
intergrated 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 caculated
results are compared with some experimental results. |
