The results show that the general chemical potential not only expands the chemical potential definition of the classical thermodynamics and field of application , but also indicates the connotation of external physical fields ' contribution to the chemical potential and effect on the chemical potential 結果表明:把化學勢推廣,不僅擴展了經(jīng)典熱力學化學勢的定義形式及應用范圍,而且表明了外場對化學勢的貢獻及影響內(nèi)涵。
Firstly , based on the utilization of the first and second law of thermodynamics , the ideal combined camot cycle model is set up . secondly , aimed at the insufficient of the classical thermodynamics analysis method , the popular method - - finite time thermodynamics analysis is applied to set up the model of endo - reversible combined carnot cycle . finally , the optimization relationships between the specific heating load ( shl ) and operating parameters and between shl and cop are conducted according to the characteristics of the function and investment of aht 在首先利用熱力學第一、二定律分析方法的基礎上,建立了吸收式熱變換器的理想聯(lián)合卡諾循環(huán)模型,然后針對經(jīng)典熱力學分析方法的不足,利用了當前很流行的有限時間熱力學分析手段,建立了aht系統(tǒng)內(nèi)可逆聯(lián)合卡諾模型,根據(jù)熱變換器的功能、投資等方面的特點,導出了吸收式熱變換器比供熱率與操作參數(shù)、比供熱率與熱力學性能系數(shù)的優(yōu)化體系。
