用氧弹热量计对甲醇、汽油以及甲醇汽油的热值进行了测定，误差控制在国家标准GB／T384—81要求的范围内。通过实验，得出甲醇汽油的热值随着甲醇比例的增加而降低。采用理论分析公式计算的热值与实验值的误差范围为4．8％～37．8％，采用传统拟合公式的误差范围为0．6％-28．2％，采用本实验新推论的拟合公式误差范围为0．2％～2．9％。

In this paper, the heat value of methanol, gasoline and methanol-gasoline were researched with oxygen bomb calorimeter, by GB/T384-81 national standard, and the results are in the range of national standard. Through experiments, the heat value of methanol gasoline increased with the ratio of methanol. The error range of theoretical analysis and experimental values is 4.8%-37.8%, using the traditional formula, the error range is 0.6%-28.2%, using a new deduction of the experimental, error range of the fitting formula from 0.2% to 2.9%. This new corollary to illustrate the quadratic approximation formula can be used as the general estimate formula fuel heating value.
