About this episode

EP.48 能運作300萬年!歷久不衰的「超電流」! 粉絲專頁:https://www.facebook.com/scientists543/ 高溫超導體新技術,研究出連兩年幾乎沒有衰減的「超電流」,不需持續供電,可持續產生磁場三百萬年! 超導磁鐵本身沒電阻,產生不會發熱的「超電流」,電流也不會衰減,但要做出一個高溫超導體很不容易,除了讓磁場穩定,因為高溫超導體本身是陶瓷結構,做線圈跟接頭是很困難… 日本理化學研究所(RIKEN)的柳澤吉紀所主導的團隊,以RE-BCO高溫超導體做出了線圈與接頭,剛開始衰減率是每小時10億分之一,到了第二年時,每小時的變化率僅有300億分之一(不供電情況下,可運行三百萬年)! 本集以高溫超導體新技術,來聊聊歷久不衰的「超電流」! #高溫超導體 #超電流 #RIKEN -- Hosting provided by SoundOn
