论文摘要
在本文中，我们考虑了两级量子热发动机的模型，以研究有限的时间操作下不同条件下的热力学数量的明确分析表达。在该发动机中，工作物质由浸入磁场中的旋转半颗粒组成。有限的热力学过程由两个量子绝热和两个量子等温过程组成。这是在两个具有反向温度$β_{1} $和$β_{2} $（$ <β__{1} $）的热储层之间工作的。在此过程中，我们在模型的最大功率输出下获得了工作，热，功率和效率。我们的最大功率效率的结果与Carnot效率一阶的通用价值一致。
In this paper, we consider a model of two-level quantum heat engine to investigate the explicit analytic expression for the thermodynamics quantities in different condition under the finite-time operation. In this engine, the working substance is composed of a spin-half particles immersed in a magnetic field. The finite-time thermodynamic processes consisting of two quantum adiabatic and two quantum isothermal processes. This processes working between two heat reservoirs with an inverse temperatures $β_{1}$ and $β_{2}$ ($<β_{1}$). In this processes, we obtain the work, heat, power and efficiency at maximum power output of the model. Our result of the efficiency at maximum power agree with the universal value in the first order of Carnot efficiency.
