| 摘 要： | 本文提出了一个新的热力性质——δ函数。 δ=θ2-θ1式中θ1与θ2为任意选定的两种基准燃料的θ函数。 对于CnHm-空气系统,δ函数只与温度有关,而与燃料氢碳比以及燃气当量比无关。借助于δ函数,编制了适用于任意燃料氢碳比（包括碳与氢）的通用燃气热力性质表。利用此表可以方便而准确地计算CnHm-空气系统在任意当量比下的燃气热力性质。文中给出了该表的样表。

| Abstract: | A new kind of thermodynamic properties is proposed which is designated by the name of b functionwhere θ1 and θ2 are θ functions of two reference fuels which, can be selected arbitrarily.The &; function is dependent only on temperature and independent of hydrogen-carbon ratio of the fuel and fuel-air ratio for CnHm-air system. With the aid of the &; function a set of generalized tables of thermodynamic properties has been worked out, which can be applied to obtaining the thermodynamic properties of CnHm-air system combustion products at any fuel-air ratio easily and exactly. A specimen of the generalized tables is given in this paper. |
