In a separate use or for the thick-walled tube welding, heat-resistant steel should use low hydrogen electrodes.

在单独使用或用于厚壁管焊接时，应选用低氢耐热钢焊条。

This practice is much more common with low hydrogen electrodes, since the core wire melts up inside the flux coating.

这种做法较为普遍，低氢焊条，因为融化的核心线内的通量涂层。

Porosity is often found when using low-hydrogen electrodes such as E-7018, and it may be difficult to establish why this occurs.

孔隙度是经常发现在使用低氢焊条例如e - 7018，它可能会难以确定为什么发生这种情况。

He had a tube with electrodes potted in it filled with atomic hydrogen. And by applying a voltage, he was able to get the gas to glow.

那是个装满了氢原子并含有电极的管子,通过增加一个电压，他让气体燃烧起来了。

When we increase the potential between the 2 electrodes that we have in the tube -- we actually split the h 2 into the individual hydrogen atoms, and not only do that, but also excite the atoms.

当我们增大两个电极之间电压,我们有-我们可以把氢气2,分解成单个的氢原子，不仅这样，还能激发原子。

This is the diagram taken right from your text, there are the two electrodes coming in and this is atomic hydrogen in the gas tube.

这是从教科书上复制下来的图表，这里有两个电极进来,这是气体管中的氢原子。

The process reverses electrolysis, which many may recall from a high school experiment that involved placing two electrodes in water, passing an electric current through them and collecting the hydrogen and oxygen that bubbled off.
