摘　　要：提出了晶体的新概念,修改了晶体中原子排列周期性的传统提法。按照晶体结构中原子是否有周期性重复排列将晶体分成了单胞晶和双胞晶两大类。New definition of 'Crystal' was expressed. The traditional expression that the atoms in crystal must have periodic arrangement was corrected. A definite physical signification for crystal was given. That is, according to the atoms of solid structure have or haven′t periodic arrangement, crystal can be classified to single unit cell crystal and double unit cell crystal.
