摘    要：本文根据我国主要煤矿和油田的200多个煤样和油样的热化学性质,利用一元线性回归分析推导出既适合煤又适合油完全燃烧时理论干空气量的计算公式L。=1.08(Q_低^用/1000)+0.11;利用二元线性回归分析分别推导出重油和煤完全燃烧时燃烧产物量的计算公大V_n=1.37(Q_低^用/1000)+11n-13和V_n=1.37(Q_低^用/1000)+6.26n-7.47。这些回归公式的回归值与理论计算值相比,误差很小;与现有经验公式相比,提高了计算精度,扩大了公式的使用范围,减少了计算层次。对工程计算具有实际意义。

Abstract: According to the thermochemical qualities of more than 200 coal-samplesand oil-samples of the main coal-fields and oil-fields of China, using themonadical linear regression analytics, an empirical formula of theoretical dry-air （L₀= 1.08（Q_L/（1000）） + 0.11） was derived which fits both coal and oil duringcomplete combustion. Based on the binary linear regression analytics, theempirical formulae （V_u= 1.37（Q_L/（1000）） + 11n - 13 and V_n = 1.37（Q_L/（1000）） + 6.26n - 7.47）of the combustion products of fuel oil and coal during complete combustionwere also perived respectively. Compared with theoretical calculation values, the regression values ofthese regression formulae have very small errors only when compared with thepresent empirical formulae, the regression formulae have improved the ac-curacy and decreased the steps of calculation and have expanded their appli-cation scope. Besides, they are of practical significance to technical calcula-tion.
