一、晶胞中质点的占有率在一个晶胞结构中出现的多个原子,并不是只为这一个晶胞所独立占有,而是为多个晶胞共用,所以每一个晶胞只能按比例分摊。分摊的根本原则是:晶胞任意位置上的原子如果是被n个晶胞所共有,则每个晶胞只能分得这个原子的1/n。具体地,对立方晶胞而言,根据晶胞(晶体中最 First, the unit cell in the occupancy rate In a unit cell structure in the emergence of multiple atoms, not only for a unit cell occupied, but for a number of unit cell sharing, so each cell can only press Proportional The basic principle of apportionment is that if an atom at any position of a unit cell is shared by n unit cells, each unit cell can only share 1 / n of this atom. In particular, for cubic cells, according to the unit cell (crystal most
