摘　　要：研究了有织构的高T_c块状样品和烧结高T_c块状样品,在磁化曲线、交流磁化率、电阻R(T)转变曲线方面的差别。结果表明,熔融织构法是增强钉扎、克服弱连接的有效方法。The hysteresis loops, a.c.susceptibility and R(T) curves have been measured and compared for the textured bulk YBCO samples and sintered samples. It was shown that the melt-textured method was effective on eliminating weak link and intersifying flux pinning.
