【Abstract】 The composition and crystal structure have been investigated by trans- mission electron microscopy and EDAX.The results show that there is tetra- gonal structure superconducting phase(a=b=5.41,c=24,21)in the Bi system superconductors.This provided theoretical basis for designing the composition of material and improving heat treatment process.更多还原
