Abstract：A quantum Carnot heat engine cycle model based on extreme relativistic particles in one-dimensional infinite deep potential well is established.The expressions of performance parameters such as power,efficiency,and effective power of the cycle are derived,and the influence of heat leakage coefficient and other parameters on the cycle performance is studied.The results show that the heat leakage coefficient has a great influence on efficiency,the working substance temperature ratio has a great influence on dimensionless power and effective power,and the probability of particles at the first excited state energy level has a significant impact on power and efficiency.The effective power is the best compromise between power and efficiency.
