摘　　要：本文论述 YBa_2Cu_3O_(7-X)粉末在镍带上成型的工艺,YBa_2Cu_3O_(7-X)—Ni 在820℃保温约3分钟后进行轧制,通过轧制形成的 YBa_2Cu_3O_(7-X)—Ni 复合带没有超导电性,经过热处理后(820℃～950℃),复合带具有超导电性,Tc>77K.Jc 值为0.1～390A/cm^2.This paper deals with the forming technique of YBa_2Cu_3O_7-x powderon Ni strip. After YBa_2Cu_3O_7-x—Ni has been heated for about 3 minutes at 820℃,YBa_2Cu_3O_7-x complex strip is formed by rolling.There is no superconductivity in this complex str -ip The Superconductivity appears in this complex Strip through heat treatment (820℃ -950℃) Its Tc is over 77k and Jc is 0.1-390A/cm^2.
