摘 要：<正> The microstructures of the YBCO composited superconducting tapes with different Jc were analysed byTEM.The relationship between microstructure and Jc of the tapes is discussed in detail.It is demonstrated thatJc value of the tapes increases significantly with the decrease in the width of grain boundary,increase of the twindensity and the reducing of the amount of precipitates at grain boundary.At grain boundary of the tapes,howev-er,small amount of non-superconducting phases can-not be avoided.For the fabrication of high Jc YBCO com-posited tapes,it is very important to improve the microstructure of the superconductor perfectly.
