摘要
该文对不同平均粒径ＹＢａ２Ｃｕ３Ｏ７－δ超导块材的双孔ＲＦ—ＳＱＵＩＤ的噪声水平的研究表明，ＹＢａ２Ｃｕ３Ｏ７－δ块材的晶粒平均粒径与其制备的双孔ＲＦ—ＳＱＵＩＤ的噪声水平呈Ｕ形关系。在１５～２５μｍ时，噪声水平很低，小于２．０×１０－３反之，噪声水平偏高。
This paper deals with the connect between the two holes RF-SQUID'snoise level and the YBa2Cu3O7-δsuperconductor bulk' s average diameter. The result is characterized by the U curve. The noise level is less than 2.0 ×10-3 / when the average diameter of the bulk is 15￣25μm, otherwise it increases.
