東南大學物理學院上傳的報告在這，有興趣的可以看看，我還未看完，不知道他們用何者方法驗零電阻
Zero resistance, which is important evidence for superconductivity, was observed above 100∘ K under ambient pressure in our experiment. Our finding indicates that Pb10−xCux(PO4)6O is a possible candidate for searching high-temperature superconductors.

應該是這個, 看 影片 比較快.
通過 1mA 的電流, 測量樣品兩端電壓, 獲得電壓值在 10^-8 ~ 10^-9 V 已達儀器極限, 以 R = V / I 計算此時電阻值在 10^-5 ohm 或以下, 認為測得零電阻. |
