摘　　要：笔者从提高能量利用率的观点出发,论述了影响热机热效率提高的因素,通过将定量的工质变成变量的工质,增加机械功,提高热机效率,并给出了提高热机热效率的措施.In terms of utilization ratio of energy, this article discusses the influencing factors of improving thermal efficiency of heat engine. The measures of improving thermal efficiency of heat engine are provided through transforming the quantitative working fluid into the variable working fluid in order to increase the mechannical work, thus impove the thermal efficiency of heat engine.

关 键 词：热效率 工质 燃烧势能 相变势能 机械功
