摘　　要：考虑横观各向同性压电材料中螺位错的亚音速运动问题。应用复变函数方法，得到了运动螺位错产生的电弹场的解析解。当螺位错的运动速度为零时，其解便退化成由Pak给出的静止螺位错产生的电弹场。The moving problem of a screw dislocation at subsonic velocity in a transversely isotropic piezoelectric medium is considered.The analytical solution for the electroelastic fields produced by the moving screw dislocation is obtained by using complex variable method.When the velocity of the moving screw dislocation vanishes,the present result reduces to the solution given by Pak［1］ for the static screw dislocation.
