The acids in the food begin to attack and dissolve the metal lining of the can, and one of the by-products of this chemical reaction is hydrogen gas.
食品中的酸性物质开始溶解罐的金属内层，这种化学反应会产生氢气。
In addition, the problem of hydrogen attack in steels is also discussed.
此外还讨论了钢中的氢蚀问题。
Hydrogen can cause hydrogen attack to the steel material while co 2 can lead to the corrosion and spitting corrosion of the process equipment.
氢气可以使金属材料产生氢损伤，二氧化碳水溶液可引起设备产生全面腐蚀和点蚀。
In addition, hydrogen sulfide may infiltrate and attack the crystalline matrix of the steel, creating conditions which can lead to weakening and failure of the steel in certain cases.
此外，硫化氢还能渗透并腐蚀钢的晶格，在某些情况下会导致钢性能的削弱甚至损坏。
The large welding current caused the formation of quenched martensite and the high residual stresses in the welding zone, resulting in the increase of zinc sensitivity of hydrogen attack.
结果表明：由于焊接电流过大，使焊缝产生淬火马氏体组织及较大的焊接残余应力，导致镀锌氢脆敏感性增加，造成吸油盘发生氢脆开裂。
