In this paper, the author is attempting to solve the thermalengineering problems by the exergetic method as follows:1. First of all, four more definite and clearer definitions of exergetic efficiency are presented. Then, separate definitions of reasonable exergetic efficiency are also given for the different kinds of thermalengineering equipments for different uses.2. Emphasis is placed on the analysis of exergy of steady flow process with perfect gas as the working substance. From such an analysis, it is shown that the exergy of a steady flow process of perfect gas can be divided into two different kinds of capabilities of work exclusive of the constant - zero exergy e0, which characterizes difference of mass transported between the steady flow and the surrounding medium. Now that the steady flow process in a fluid machine with perfect gas as the working substance can be described by stagnation enthalpy exergy ei* and stagnation pressure exergy ep* instead of stagnation enthalpy i* and stagnation pressure p*. And that two different kinds of capability of work can be distinguished and eventually a further development of exergetic analysis can be brought about.3. The objective function of the malengineering equipment is so depicted by the exergetic efficiency as to examine whether more reasonable result can be made otherwise with the traditional approach of analysis through its objective function-thermal efficiency. According to the author, that will depend on the coherence of variation of exergetic efficiency against the parameter analysed with that of thermal efficiency. As the coherence does not appear, the more reasonable result can be obtained. Otherwise, that will never be obtained.4. Referring to the exergetic analysis of weak part where improvement must best be made, it carried out by use of an example, it is shown that the weak part can only be determined correctly in virtue of the following approaches:(1) By comparing the magnitudes of exergy losses for various parts in a given equipment.(2) By comparing the magnitudes of exergy losses at the same part of different kinds, of thermalengineering equipments.(3) By rigorously distinguishing two different kinds of exergy losses i.e. stagnation enthalpy exergy losses and stagnation pressure exergy losses.

本文在热工问题的(火用)分析方面作了下列各项工作: 1.提出了四种工程意义明确而又严密的(火用)效率定义,并分别对各种具体情况提出了各类热工设备的合理的(火用)效率定义。 2.对高速稳定流动的理想气体工质的作功能力(总(火用)e~*),进行了分析,分析指出除常数零(火用)e_0外,总(火用)e~*系由两类不同质的作功能力所组成,由此引入了两个新概念:总焓(火用)e_i*和总压(火用)e_p*。由于新概念的引入,就区分了两类不同质的作功能力,这是热工问题(火用)分析的一个新发展。 3.指出了用(火用)分析法进行热工设备的最优分析,能否得到比热效率法更为合理的结果,这需视两种分析法的目标函数随分析对象的变化是否一致而定。 4.关于薄弱环节(火用)分析,本文指出了薄弱环节的确定,不仅需要进行纵的比较,而且还需要进行横的比较,也要注意区分两类不同质的作功能力((火用))的损失。
