通过国际比对反馈改进一级功率标准
Improvement of primary power standard through international comparison feedback
摘要：
高频主功率标准是唯一实现的同轴微量热计，至少高达40 GHz的装置。同轴式微量热计是一种宽带测量系统，适用于测量热辐射型和热电型功率传感器的有效效率。实现功率标准的关键是确定微量热计的校准常数g，g是一个与频率有关的参数，它对标准的准确度评估有很大影响。本文提出了一种利用微量热仪参与的国际比对所提供的参考值来提高其准确度的简单而有力的方法。
英文摘要：
The high frequency primary power standard is univocally realized by means of a coaxial microcalorimeter, at least up to 40 GHz. The coaxial microcalorimeter is a broadband measurement system adjusted for effec-tive efficiency measurement of power sensors both of bolometric and thermoelectric type. The critical point in the power standard realization is in the determination of the calibration constant g of the microcalorimeter, a frequency dependent parameter that has huge impact on the accuracy as-sessment of the standard. The paper proposes a simple but powerful way for improving this accuracy by using the reference values provided by in-ternational key-comparisons which the microcalorimeter was involved in.
