本文介绍了用自制的简易装置代替专用设备——烧氢炉制做高质量直热式钡钨阴极的方法。
In this paper, a method of making high-quality direct-heated barium tungsten cathode using a home-made simple device instead of a costly special device hydrogen oven is introduced.
当你在烧氢类燃料(如石油)时，燃料中的氢原子和碳原子与空气中的氧结合反应，生成了二氧化碳和水。
When you burn a hydrocarbon fuel such as oil, its hydrogen and carbon atoms combine with oxygen from the atmosphere to create water and carbon dioxide.
相比之下(这里应该是指相比于制造氢燃料电池)，将传统内燃机由烧油改为烧氢气要容易一些。即使是这种尝试也没有结果。
By comparison, getting a conventional internal-combustion engine to burn hydrogen instead of petrol is relatively easy.Even so, such efforts have also come to naught.
在避免烧穿的前提下增大焊接电流能够减小硬度、减少上贝氏体，从而降低氢致开裂敏感性。
The increase of weld current can reduce the hardness and the content of upper bainite, and lower the sensibility of hydrogen cracking of the joints.
