摘　　要：求解了在材料的特征方程有重根时，三维压电弹性体的单位集中不连续位移和不连续电势基本解。讨论了重根对断裂力学问题解的影响。The displacement discontinuity and potential discontinuity fundamental solutions (DDFS), which are of great importance in the analyses of crack problems with Boundary Integral Equation Method (BIEM), are obtained for the case that the material characteristic equation of piezoelectric medium has identical roots. This is the complementary part of the pevious studies .
