Therefore, it is regarded that the formation of atomic lead is mainly dependent on the thermal dissociation of lead oxide and the reduction of lead oxide by carbon is slower.

从而认为铅原子的形成主要靠气态氧化铅的热解，而碳还原反应则是缓慢的。

This would lessen the need to burn coal and oil, and lead to reduced emissions of carbon dioxide and nitrous oxide.

BBC: Impact of global warming may be severe and wide-ranging

That would change the way the magnetic field of the iron oxide interacts with the semiconducting behaviour of the lead selenide.
