arc constriction

基本解釋

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(xiàn)并不一定產(chǎn)生陽極熔化和出現(xiàn)陽極班點，這可用塌縮時間的概念得到解釋。本文應用磁流體不穩(wěn)定性原理，對實驗現(xiàn)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(wěn)定性、進而提高陶瓷件切割質(zhì)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.

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。
