摘　　要：该文计算了碱金属热电转换器在不同的工作温度和不同BASE面电阻下当输出最大电极功率密度时的电极效率 ,推导出了在给定工作温度和BASE面电阻时取得最大电极效率的条件 ,并计算了最大电极效率点和最大电极效率 ,对在给定工作温度下BASE面电阻和单位面积电极表面的热辐射量对最大电极效率及其工作点位置的影响从理论上进行了推导。The electrode efficiency of AMTEC is calculated at different working temperatures and for different BASE surface resistance values when the electrode power density output is maximum. The condition in which the electrode efficiency is maximum at given working temperature and for given BASE surface resistance is deduced, the maximum electrode efficiency and its working point are computed. The influence of BASE surface resistance and the radiation heat transfer from unit electrode surface to condenser surface on the maximum electrode efficiency and its working point is discussed.
