摘要介绍了多种构型的高稳定度标准电阻,并应用新型量子霍尔电阻测量系统跟踪测量多种无需使用油槽的高稳定度标准电阻。实验表明新型设计的无源无控温高稳定度标准电阻在室温环境中温度系数和24h噪声分布均优于传统商用型标准电阻,年相对漂移率<5×10^-7。跟踪测量实验还发现某些种类的高稳定度标准电阻具有温度弛豫效应,对于10-8量级准确度的测量,应提前3d进行控温并跟踪测量,以保证测量准确度。

Abstract：Several kinds of ultra-stable standard resistor were introduced. A new type quantum Hall resistance (NQHR) sample was developed. On the basis of the new type NQHR sample application, several kinds of ultra-stable standard resistor were measured without oil bath. Measurement data shows a new type passive ultra-stable resistor without temperature control having better performance than the tradition commercial resistor both in 24h noise distribution and temperature coefficient behaviors. Long term tracking measurement of the ultra-stable resistor indicated ultra-stable resistor has temperature delay effect. For better measurement, temperature control should be applied at least 3 days before measurement.

Key words： metrology ultra-stable standard resistor quantum Hall resistance uncertainty
