double wedge

英 /ˈdʌbl wedʒ/美 /ˈdʌbl wedʒ/
  • 双楔形：在几何学中，双楔形是两个边界不平行的半空间的对称差（闭包）。例如，在笛卡尔平面中，正象限和负象限的并集形成一个双楔形，在二维空间中，双楔形由一对由两条线定义的垂直角度内的点集组成。在射影几何中，双楔形是线段的射影对偶。

英英释义

  • In geometry, a double wedge is the (closure of) the symmetric difference of two half-spaces whose boundaries are not parallel to each other. For instance, in the Cartesian plane, the union of the positive and negative quadrants forms a double wedge, and more generally in two dimensions a double wedge consists of the set of points within two vertical angles defined by a pair of lines..
