为此，本文仅就西南红壤和黄壤中氧化物及游离氧化物进行了初步探讨。

The relationship between free oxide and soil development in south western district of China is also discussed in this paper.

假定如果没有探测到游离铁，则金属表面就是足够清洁以形成均一的氧化物膜的。

The assumption is made that if there is no detectable free iron, the metal surface is clean enough for a uniform oxide film to develop.

结论烯烃臭氧化物的形成及其臭氧链异构的反应历程，属游离基型的可能性更大。

Conclusion the form of the alkene ozone oxide and its reaction course of ozone chain isomerization are likely to be the free radical ones.
