摘要翻译：
在有限时间热力学框架下研究了一类循环布朗热机。对于无限长的循环时间，发动机工作在卡诺效率极限，但产生零功率。对于最大功率下的效率，我们得到了一个与内可逆Curzon-Ahlborn效率不同的通用表达式。我们的结果用一个工作在与时间相关的调和势中的简单一维引擎来说明。

英文摘要：
We study a class of cyclic Brownian heat engines in the framework of finite-time thermodynamics. For infinitely long cycle times, the engine works at the Carnot efficiency limit producing, however, zero power. For the efficiency at maximum power, we find a universal expression, different from the endoreversible Curzon-Ahlborn efficiency. Our results are illustrated with a simple one-dimensional engine working in and with a time-dependent harmonic potential.
