摘　　要：核电池中换能材料的粒子输运对核电池的输出性能有重要的影响。利用MCNP软件,分析了辐射伏特效应核电池的性能。结果表明:电子在GaN中的最大射程为87μm;随着电子的入射角度增大,能量反射率越大,入射角度选取0°~25°;能量沉积的灵敏区不超过35μm;外电路的电学参数对应GaN中不同的掺杂浓度和内部电势。The transport of particles in energy-exchange materials of nuclear batteries has an important effect on the output performance of nuclear batteries.This paper uses MCNP software to analyze the performance of radioactive voltaic effect nuclear battery.The results show that the maximum range of electrons in GaN is 87μm;as the incidence angle of the electrons increases,the energy reflectivity increases,with the incidence angle to be from 0°to 25°;the sensitive area of energy deposition does not exceed 35μm;the electrical parameters of the external circuit correspond to different doping concentrations and internal potential in GaN.
