从单个热浴中提取功
Extracting Work From A Single Heat Bath
摘要:
我们在这里提出一个机器,是能够提取的工作,从一个单一的热浴。虽然在机器的操作中不涉及显著的温度梯度,但是可以实现高达1的卡诺效率。这台机器的工作原理是根据麦克斯韦提出的一个恶魔来解释的。利用溶液中分子的动能谱,恶魔可以将“更热”的分子以牺牲其自身能量为代价发送到更高的引力势。由于浓度梯度和半透膜的使用而产生的化学势差确保了连续的循环过程。
英文摘要:
We present here a machine that is capable of extracting work from a single heat bath. Although no significant temperature gradient is involved in the operation of the machine, yet the Carnot efficiency as high as one is achievable. Working of the machine is explained on the basis of a demon suggested by Maxwell. Utilizing the kinetic energy spectrum of the molecules in solution, the demon can send "hotter" molecules to a higher gravitational potential at the expense of their own energies. Difference in chemical potentials due to concentration gradients and use of semi-permeable membranes ensure the continuing cyclic process.
