摘要

以等离子体基本方程为依据

推导出了在真空电弧弧柱外的电子密度沿径向呈指数规律减、弧柱内呈二次曲线率减的结果。提出将弧拉内、外分界点到电弧中心的距离作为电弧半径及其确定方法的建议。实验结果与理论分析基本吻合。

Abstract

On the basis of plasma basic equations the calculation result which is in great confomity with the experimental one shows that electron density in vacuum arc distributes according to conical section just inside the arc columnar

while out of arc columnar according to exponent principle which is tangent with conical section just at the edge of arc columnar

thus the arc radius is determined.
