Bipyramid - Wikipedia
网页A bipyramid is a polyhedron constructed by fusing two pyramids which share the same polygonal base; [1] a pyramid is in turn constructed by connecting each vertex of its base to a single new vertex (the apex) not lying in the plane of the base, for an - gonal base forming triangular faces in addition to the base face.

Triangular bipyramid - Wikipedia
网页In geometry, the triangular bipyramid is the hexahedron with six triangular faces, constructed by attaching two tetrahedra face-to-face. The same shape is also called the triangular dipyramid [1] [2] or trigonal bipyramid. [3] If these tetrahedra are regular, all faces of triangular bipyramid are equilateral.

Dipyramid -- from Wolfram MathWorld
网页2024年8月22日 — A dipyramid, also called a bipyramid, consists of two pyramids symmetrically placed base-to-base. The dipyramids are duals of the regular prisms. Their skeletons are the dipyramidal graphs. The volume of a dipyramid of half-height and base area is equal to twice the volume of the corresponding pyramid, namely. (1)
AuPt Bipyramid Nanoframes as Multifunctional Platforms for In …
网页2019年3月21日 — This is the first report of bipyramid-like nanoframes and a template-free method under mild conditions. This configuration merges the plasmonic features of Au and highly active catalytic sites of Pt in a single nanostructure, making it an ideal multifunctional platform for catalyzing and monitoring the catalytic reaction in real time.
