| 摘 要： | 依据P3121(D34)空间群的对称性,认为α石英晶体的元胞包含6个SiO2分子,某元胞常数应为c=1.0788nm,α=0.4904nm。同时,用实验证实了这个观点。关键词：

| Abstract: | Based on the symmetry of the space group P3121(D34), we consider that there are six molecules per primitive cell in a-quartz, and the constants of the primitive cell should be c = 1. 0788 nm and a = 0. 4904nm This point of view has been confirmed by our experiment. |
