【摘要】 本文介绍在液氦温度下对国产铌材（Nb2-1）超导微波表面电阻的实验研究。测量是在X波段TE₀11模式腔上进行的。温度在4.2K时无载品质因数Q₀为4.3×10⁶,相应的剩余表面电阻为1.8×10^-4Ω。更多还原

【Abstract】 The experimental research of the superconducting microwave surface resistance with China’s niobium material (Nb2-l) at the liquid helium temperature is described. The measurement is made on X-band TE011 mode cavity. Unloaded Q0 value of 4.3×106 is achieved at a temperature of 4.2 K. The equivalent residual surface resistance is 1.8*10-4Ω.更多还原
