摘　　要：基于Stroh理论，研究了含N个共线刚性线夹杂压电介质的广义二维问题，给出了介质内的复势函数、夹杂内的电场和夹杂尖端附近场奇异性系数的解析表达式。结果表明场奇异性系数取决于无限远处的应变。The generalized two-dimensional problem of piezoelectric media with collinear r i gid line inclusions is studied based on Stroh formalism. The explicit expression s for complex potentials in the media, electric field inside inclusions and sing ular coefficients near the inclusion tips are given, respectively. It is shown t hat all the singularities of field depend on the strain at infinity.
