摘要：

Carbon aromaticities for a further 15 bituminous coal samples, including vitrinite and semi-fusinite maceral concentrates, have been obtained by solid state C-13 NMR using the quantitative single-pulse excitation (SPE) technique, to add to the results for samples reported previously (Fuel, 1994, 73, 1926). A virtually identical linear correlation between the aromaticity (values in the range 0.73-0.91) and atomic WC ratio holds for the new samples investigated, confirming that it is independent of both inertinite content and geological provincialism.
