A trigonal bipyramid has three equatorial and two axial positions. 一个三角双锥体有三个赤道位和两个轴向位。
Diamond crystats are intermediate between dihydrate and monohydrate calcium oxalate,two crystal forms:pyramide and bipyramid,therefore,it is not dihydrate calcium oxalate. 本研究发现菱形晶属于一水和二水草酸钙的中问晶体,菱形晶有两种晶体形式,单锥和双锥的结晶形式,菱形晶不是二水草酸钙。
