摘　　要：本文研究了高温超导３×３并联ＤＣＳＱＵＩＤ串联阵列台阶约瑟夫森结。其性能指标：７７Ｋ下，磁通白噪声为８．９×１０－５Φ０／Ｈｚ，磁场灵敏度在白噪声段为２×１０－１１Ｔ／Ｈｚ．研究表明。Abstract HTS 3×3 parallel DC SQUID series step edge Josephson junction arrays are studied. The performance of one device is that the magnetic flux white noise is 8.9×10 -5  0/Hz 1/2 and the magnetic sensitivity in white noise regime is 2×10 -11 T/Hz 1/2 at 77K. It indicates taht the parallel of Josephson junctions might give a good compensation to substrate step edge Josephson junctions which have dispersive parameters.
