Otherwise, the volume of the crystal unit cell increase slightly with no regularity after doping.

另外，掺质后，晶体的单胞体积一般略有增大，但未呈现出规律性。

This paper has presented the results of TEM studies about the unit cell para-meters, micro-twinning structure, crystal defect and lattice fringe image of grandidierite discovered in China recently.

本文报道了我国最近发现的硅硼镁铝矿晶胞参数、微双晶结构的电子衍射分析，晶体缺陷和矿物高分辨点阵象的透射电镜观测结果。

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.

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。
