解釋
鈧酸鹽-
Since non - uniform electronic emission, poor recovery after ion bombardment and too expensive of sc2o3, scandate cathode has not been vastly used
但含鈧擴散陰極存在發射均勻性不好、抗離子轟擊性差以及價格昂貴等因素的制約而沒有獲得廣泛的應用。 -
Scandate cathode has outstanding properties of high emission at low work temperature. it ’ s the only thermionic cathode which can suffice to the development of new electronic device ’ s requirement
含鈧擴散陰極具有極其優異的低溫高電流密度的電子發射的能力，是目前唯一能滿足新型電子器件發展要求的熱陰極材料。
