从汽轮机能量平衡的角度出发，对汽轮机相对内效率两种定义方法进行了分析。
Firstly, two defining methods of relative internal efficiency for steam turbine are analyzed from energy equilibrium.
采用指示性相对内效率的定义，提出当量汽态线的概念，并据此推导出相应的汽轮机热耗计算模型。
Adopting the definition of indicated relative internal efficiency, the concept of equivalent condition curve was proposed and corresponding turbine heat rate model was derived.
目前采用的汽轮机理想循环热效率受到相对内效率影响而不能准确反映汽轮机热力系统运行经济状态。
The ideal cycle heat efficiency used nowadays is affected by the relative internal efficiency so it can't reflect the operation economic state of thermal system of steam turbine.
