明弧
... apparent anomaly ==> 视近点角 apparent arc ==> 明弧 apparent area ==> 名义面积,表观面积 ...
采用应力法计算不同半径处的表观应力强度因子,插值到裂尖圆弧而得。
In arc ignition process, it has apparent effect and improves the stability of arc, so that power factor is advanced and current drain is reduced.在引弧过程中,有明显的效果,提高了电弧的稳定性,从而使功率因数是先进的,漏电流减少。
