To assess the thermal contribution from oxidation reaction, the standard formation enthalpes of all reactants and products were used to calculate the oxidation enthalpies. It could be found that all oxidation reactions were exothermic. And oxidation played a more important role during the toluene trinitration at high temperature, because the reaction temperature of toluene trinitration is the higher than mononitration and dinitration, and the temperature coefficient of oxidation is higher than that of trinitration too.

Denitrification：反硝化作用

主要來源於硝化作用(Nitrification)與反硝化作用(Denitrification), 由硝化菌通過氧化將NH3轉(zhuǎn)化為NO2, 或少量由沒有氣氧能生活的細(xì)菌經(jīng)過反硝化作用將NO3轉(zhuǎn)化為NO2.
