摘　　要：油品的热值是其最主要的参数之一,测量其燃烧热对于认识其性质具有重要的意义。通过氧弹量热计测定汽油的燃烧热值,计算汽油的高、低位热值,拓展了理工科物理化学实验课程的教学内容。采用胶囊法装取油品,进行汽油燃烧热的测定,该方法重现性好、准确度高、操作简便。实验教学实践表明,该实验的教学效果优于传统的萘燃烧热测定实验。The value of combustion heat is one of the main parameters of fuel. Therefore, determining the combustion heat of fuel is important to know the properties of fuel. Determining the combustion heat of gasoline in oxygen bomb calorimeter and calculating the whole and neat heat of gasoline expanded the content of physical chemistry experiment for science and engineering students. The combustion heat of gasoline was determined via the combustion of medical capsule containing gasoline sample. The method was reproducible, accurate and simple. The experimental teaching research proved that the present experiment was better than the conventional determination of combustion heat experiment using naphthalene as reactant.
