本文以循环一次所需时间为自变量,导出当循环以不同速率进行时,二热源机的输出功率和热效率的表达式,并以特例作出曲线,展示二者随循环一次所需时间的变化规律;同时导出输出功率的最大值及与之对应的热效率。
In this paper, the time required to cycle once is taken as an independent variable to deduce the expressions of output power and thermal efficiency of two heat source machines when the cycle is performed at different rates. The curves of the two heat source machines are plotted to show the variation rules of the two with time ; At the same time export the maximum output power and its corresponding thermal efficiency.
