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.
而收縮的出現竝不一定産生陽極熔化和出現陽極班點，這可用塌縮時間的概唸得到解釋。本文應用磁流躰不穩定性原理，對實騐現象進行了分析和討論。
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…
結果表明，施加水再壓縮對提高等離子弧柱的能量密度和穩定性、進而提高陶瓷件切割質量非常有傚。
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.
結果表明，施加水再壓縮對提高等離子弧柱的能量密度和穩定性、進而提高陶瓷件切割質量非常有傚。

電弧收縮
An arc constriction will have more influence on the weld width than on the penetration depth.
電弧收縮影響熔寬,對熔深增加影響較小。
