THE CHARACTERISTICS OF NUCLEAR MAGNETIC RESONANCE AND PARAMAGNETIC RESONANCE SPECTRA IN METAMORPHIC SERIES OF SAPROPELIC COAL
-
摘要: 利用核磁共振和顺磁共振谱对等变质系列的腐泥煤和腐殖煤进行了对比研究,两种谱图清楚地表现出两个变质系列各煤阶的峰形和峰值都有明显的区别。Abstract: The sapropelic coal and humic coal are studied using the nuclear magnetic resonance and paramagnetic resonance spectra.The NMR and ESR spectra show clearly that the peak shapes and peak values are differentiated obviously in the coals with same metamorphic series and different ranks.
