一个合理的效率定义模式，应该从绝对量（损）和相对量（效率）两个角度准确地体现设备的热力学完善度—设备实际状况接近理想可逆状况的程度。从这一点出发，通过对蒸汽透平、燃气轮机等动力设备现行目的效率表达式的探讨，对该类设备的效率定义模式提出了不同的看法，给出了一种能够准确反映其热力学完善度的效率表达式 A reasonable model of efficiency definition should accurately reflect the thermodynamic integrity of a device from two perspectives: absolute (loss) and relative (efficiency) - the degree to which the actual state of the device approaches the ideal reversible condition. From this point of view, the current efficiency of steam turbine, gas turbine and other power equipment, the purpose of the efficiency of the expression of discussion, on the efficiency of this type of equipment defines the definition of different views, gives a can accurately reflect the thermodynamic perfection Degree of efficiency 表 expression
