摘要
利用热力学的普遍理论推导了范德瓦尔斯气体热力学函数的表达式,再求出绝热过程和3种等值过程中功和热量的表达式.在此基础上,研究了斯特林循环、奥拓循环和狄塞尔循环的功和效率,并计算和分析了3种循环效率随各种参量变化的关系.
Using the general theory of thermodynamics,we deduced the expressions of thermodynamic functions of Van der Waals gas,and calculated the expressions of work and heat in the adiabatic process and three kinds of equivalent process.Based on that,we studied the work and efficiencies of Stirling cycle,Otto cycle,and Diesel cycle.Relationships between the three kinds of cycle efficiency and the change of various parameters were calculated and analyzed.
