标准摘要
[中文适用范围]： 本部分IEC 61788描述了通过标准双谐振器法在微波频率下测量超导体表面电阻（Rs）的方法。测量对象是谐振频率下Rs的温度依赖性。 该方法的适用测量范围如下： - 频率：8 GHz < f < 30 GHz - 测量分辨率：在10 GHz时为0.01 mΩ 报告测量频率下的Rs数据，并假设f²规则进行比较，将其缩放到10 GHz。 [外文原描述]： IEC 61788-7:2020 describes measurement of the surface resistance (Rs) of superconductors at microwave frequencies by the standard two-resonator method. The object of measurement is the temperature dependence of Rs at the resonant frequency. The applicable measurement range of Rs for this method is as follows: - Frequency: 8 GHz < f < 30 GHz - Measurement resolution: 0,01 m Ω at 10 GHz The Rs data at the measured frequency, and that scaled to 10 GHz, assuming the f 2 rule for comparison, is reported. This third edition cancels and replaces the second edition, published in 2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) informative Annex B, relative combined standard uncertainty for surface resistance measurement has been added; b) precision and accuracy statements have been converted to uncertainty; c) reproducibility in surface resistant measurement has been added.
