摘　　要：利用复变函数的保角映射及罗纶级数展开法对在无穷远处受非均匀反平面剪应力场及非均匀平面电位移场作用下的内含螺旋位错和椭圆夹杂的压电材料作了理论分析 。The main objective of this research is to find a suitable solution about a screw dislocation interacting with an elliptical p eiezoelectric inhomogeneity in piezoelectric material under remote non-uniform antiplane shear & inplane electric field.The analysis is based on the use of conformal mapping and laurent series expansion of the complex potentials.The expressions for the field are provided in the transformed plane.
