showed a trendno p-value reported

Under 25mL/min and 50mL/min air volume conditions, the average activation energy of pre-oxidized coal samples in the high temperature oxidation stage showed a trend of first decreasing and then increasing with the increase of preset temperature conditions in the range of 40°C-110°C and 110°C-170°C.
