A quasidislocation (a dislocationlike entity described here for the first time) moves at the speed of a Stoneley surface wave that travels at the interface between two different elastic solids. An Eshelby glide edge dislocation moves at the speed of a Scholte surface wave that travels at the interface between a solid and an ideal liquid. The quasidislocation and the glide edge dislocation (that moves at the Eshelby velocity) are the Green's functions of their waves. Scholte waves are planar distributions of transonic moving glide edge dislocations. They are not Stoneley waves, although often called by that name, because Stoneley waves are planar distributions of subsonic moving quasidislocations.
一种准位错(此处首次描述的类似位错的实体)以斯通利表面波的速度移动,该表面波在两种不同弹性固体的界面处传播。埃舍尔比滑移刃型位错以肖尔特表面波的速度移动,该表面波在固体与理想液体的界面处传播。准位错和(以埃舍尔比速度移动的)滑移刃型位错是其波的格林函数。肖尔特波是跨音速移动的滑移刃型位错的平面分布。它们不是斯通利波,尽管常被这样称呼,因为斯通利波是亚音速移动的准位错的平面分布。
