对北威尔士土壤数据的检验表明，用廷斯利的方法测定的燃失量和有机碳值之间存在着良好的相关性。在850[度]C的温度下点火半小时，在375[±]5[度]C的温度下点火16小时。后一种程序比前一种程序有优点。根据所得数据，给出了烧失量有机碳的回归线和预测限。虽然这些回归不一定是普遍适用的，但对一些已发表的数据的检查表明，非常相似的表达可能是适用的。该方法，由于其简单，可以有效地应用于广泛的调查，分析和生态研究，尽管已知的错误来源。
Ex-amination of data on North Wales soils shows that a good correlation exists between loss-on-ignition and organic-C values, determined by Tinsley''s method. Ignition for half an hour at 850[degree]C, and for 16 hours at 375 [plus or minus] 5[degree]C have both been employed. The latter has advantages over the former procedure. Regression lines and prediction limits for organic-C from loss-on-ignition are given from the data obtained. Although these regressions are not necessarily expected to be generally applicable, examination of some published data suggests that closely similar expressions may be. The method, because of its simplicity, can be usefully applied in a wide range of survey, analytical and ecological studies, in spite of the known sources of error.
