We investigate the validity of using the low-dissipation model (LD model) to describe the maximum power regime of the endoreversible model under Newton's law of cooling. We find it valid only when the temperature difference of heat reservoirs ($T_h-T_c, T_h>T_c$) is small. Thus the efficiency at maximum power derived from the LD model is valid to the first order of Carnot efficiency when describing endoreversible heat engines. We conclude that the LD model produces the Curzon-Ahlborn efficiency (${\eta }_{\text{CA}}=1-\sqrt{T_h/T_c}$) in the maximum power regime with no dependence on dissipation ratios.

低耗散模型的适用性：牛顿冷却定律下的卡诺式热机。

我们研究使用低耗散模型（LD模型）描述牛顿冷却定律下可逆模型的最大功率范围的有效性。我们发现只有当蓄热器的温差（${Ť}_H-{Ť}_C， {Ť}_H>{Ť}_C$） 是小。因此，当描述内可逆热机时，从LD模型得出的最大功率效率对卡诺效率的一阶有效。我们得出结论，LD模型产生了Curzon-Ahlborn效率（${\eta }_{\text{认证机构}}=\mathrm{1个}-\sqrt{{Ť}_H/{Ť}_C}$）在最大功率范围内，不依赖于损耗比。
