摘　　要：利用计算机对20种林业机械常用钢的回火温度与化学成分,回火硬度关系进行研究,通过曲线拟合、定积分计算等方法,设用并计算出它们的化学成分当量,用回归分析方法得出了钢的回火温度方程:T=621.4—13.6H+331.6M。The relations of tempering temperature, chemical compositions and tempering hardness of twenty kinds of steel used in forestry machines were studied in this paper. Firstly, the chemical compositions equivalent were calculated. Secondly, based on regression analysis method, the equationof tempering temperature was set up: T = 621.4-13. 6H +331.6M

关 键 词：化学成分当量 回火温度方程 林业机械
