摘　　要：本文论述了高温预先热处理对YBa_2Cu_3O_(7-x)的组织和J_c的影响,通过此工艺可明显减少YBa_2Cu_3O_(7-x)的空洞和消除BaCO_3,经过高温预先热处理后的YBa_2Cu_3O_(7-x),它的J_c达到1140A/cm^2。This paper deals with high-temperature preheat trement to affect the structure and Jc YBa_2Cu_3O_(7-x) The hole of YBa_2Cu_3O_(7-x) is reduced obviously and BaCO_3 is removed by this process. Jc of YBa_2Cu_3 O_(7-x) reaches 1140/cm^2 through high-temperature preheat treatment.
