摘　　要：空间计量是保证地外空间测量单位统一、测量准确可靠的技术和管理活动。以研究空间计量为出发点,选用标准电阻器和电压基准器作为研究对象,探索空间应用电学标准器的地面验证试验硬件平台,设计了一套地面验证试验平台,通过对设计平台测量不确定度分析,测量不确定度可以达到10^(−5)量级,为开展空间计量需求奠定基础,但是该系统仅针对一定范围的实物电阻和特定电压量值进行了验证,对于其他电学标准器的地面验证系统还需进一步研究。Space metrology is a technical and management activity that ensures the uniformity,accuracy,and reliability of measurement units in outer space.Focusing on space metrology,this study selected standard resistors and voltage references as research subjects,exploring a ground test hardware platform for space application electrical standards.A ground verification test platform was designed,and through measurement uncertainty analysis,it was determined that the measurement uncertainty could reach the 10^(-5)level,laying a foundation for addressing spatial metrology requirements.However,this system has only been verified for a certain range of physical resistors and specific voltage values.Further research is required to develop ground verification systems for other electrical standards.
