Thereafter, the method comprises completely reducing the metal oxides and melting the metal in a smelt reduction stage.
其后，该工艺还包括在熔炼还原阶段使金属氧化物全部还原以及使金属熔融。

Reduction extraction, the electrochemical. the activation and the surface analysis methods used in determination of gas in these low melting and volatile metals are particularly outlined.
认为采用石墨盒或金属包套的惰气熔化法是目前分析易挥发金属中氢、氧的普遍方法。
