【Abstract】 (1) The new classifications of Soviet and Chinese coal proposed by Chwang Chien-ting (Acta Geologica Sinica, Vol. 36, No. 1, 1956) are criticized as the erroneous results of ignoring the well-known facts in coal chemistry and of the illogicality of method of investigation.(2) Qualitatively speaking, most of the general relationships between the proximate and ultimate composition of coal and the degree of coalification mentioned by Chwang are already well-known to coal chemists, but some are in contradiction to the well-known facts. Quantitatively, most of the relationships are not exact enough to serve as general relationships.更多还原
