However the residual effects are damaging, as they result in skiers and instructors stuck with a wedge and a wedge movement pattern.
但残余影响的损害，因为他们在滑雪和一个楔子，并打进了一个运动模式，坚持教师的结果。

The formation of the bottom hole rock-disintegrating track of the mono-cone bit with wedge teeth was studied, and simulation software for the track pattern was developed.
In this Paper, a summary of Geometrical Theory of Diffraction (GTD) by a curved surface and a straight wedge, and its application to calculation of antenna pattern is given.
