摘要
应用顺磁共振技术研究了不同变质煤的自由基浓度随温度变化的基本规律,得出了2个结论:自由基浓度增加的速率低变质煤大于高变质煤;氧化作用的难易程度不取决于原煤中的自由基浓度,而是在开始氧化后,自由基浓度增加的速率。
The basic law governing the density changing of free radical in different metamorphic coal was investigated with the assistance of the Electron paramagnetic resonance （EPR） and two conclusions were gained. The growing rate of the density in lowly metamorphic coal is higher than that in highly metamorphic coal. The proneness of oxidation depends not on the free radical density in the raw coal, but on the growth rate after being oxidation.
