摘　　要：针对不同热电子库组成的电子热机和制冷机系统,本文运用费米—狄拉克统计分布计算了在球坐标下两不同热电子库的净电子流密度随能量的分布函数,进而得到相应的热流.接着,计算了电子热机和制冷机各性能参数,数值模拟出该机的优化性能特征曲线.从而得到提高电子机工作性能的方法.To the electron heat engine and refrigerator system which consist of two different electron reservoir, the density of net electron flow was calculated as the distribution function of energy in different electron reservoirs in spherical polar coordinates based on Fermi-Dirac statistical distribution in this paper. Moreover, the corresponding heat flow was obtained. Next, the several performance parameters of electron heat engine and refrigerator were derived. The performance characteristic curves were plotted by numerically analysis. Then the methods for improving performance of the system are obtained.
