The effects of welding force and welding electriccurrent on the tensile strength of mash seam welded joints in the interstitial-free (IF) steel have been studied.
研究了焊轮压力和焊接电流对无间隙原子钢(if钢)压平缝焊接头抗拉强度的影响。

They had proven that different tones would vary the strength of an electriccurrent in a wire.
他们已经证明,不同的声调,不同强度的电流在一个丝。

In the accelerating field, every unit adjusts its current by electric field strength, the total current remaining constant.
