氧气

Tonglu: composite or pure copper radiator heating system in the use of one-pipe is dangerous, because one-pipe system, high-speed hot water would have a copper corrosion, should carefully chosen.

然而由于钢制散热器怕水中的氧气，它对供热系统要求很严格，在不安全的系统中会出现腐蚀（腐蚀点大部分在管壁上，而不在焊接部位）；而另外一个事实是，目前我们国内的许多采暖系统还不是很完善，虽然国家对采暖水质早有规定，但仍有许多物业不能按标准执行。

The ratio of oxygen to electric steel and the recycling rate of scrap differ in a wide range.

氧气电炉炼钢所占的比例以及垃圾回收率在很大程度也有不同。
