arc constriction

基本解释

However, the constriction of arc-column can not affirm arising anode melting and anode spot, which can be explained by an idea of collapse time.
而收缩的出现并不一定产生阳极熔化和出现阳极班点，这可用塌缩时间的概念得到解释。本文应用磁流体不稳定性原理，对实验现象进行了分析和讨论。
It is shown that the water constriction is effective on improving the energy density and stability of the arc, so the cutting quality can be improve…
结果表明，施加水再压缩对提高等离子弧柱的能量密度和稳定性、进而提高陶瓷件切割质量非常有效。
It is shown that the water constriction is effective on improving the energy density and stability of the arc, so the cutting quality can be improved also.
结果表明，施加水再压缩对提高等离子弧柱的能量密度和稳定性、进而提高陶瓷件切割质量非常有效。

电弧收缩
An arc constriction will have more influence on the weld width than on the penetration depth.
电弧收缩影响熔宽,对熔深增加影响较小。
