| 摘 要： | 采用同步辐射形貌术结合化学腐蚀法，系统研究了ＮＹＡＢ和ＮＧＡＢ晶体中的孪晶结构。已经发现：ＮＹＡＢ晶体中的孪晶为反演孪晶，主晶和孪晶结构具有互为中心对称关系；而ＮＧＡＢ晶体中的孪晶为１８０°旋转孪晶，孪晶结构由主晶结构绕结构的三次对称轴旋转１８０°而成。 |
| 关 键 词： | 同步辐射形貌术 孪晶结构 化学腐蚀法 |

| Abstract: | The twins in NYAB and NGAB crystals were investigated by synchrotron radiation topography and chemical etching method. It is found that the twin in NYAB crystal is the inversion twinning in which the structures of two twinned crystal pairs have the central inversion relationship. Whereas the twin in NGAB crystal is the 180 rotation twinning in which the twofold axis is along the threefold axis of the structural symmetry. |
| Keywords: | synchrotron radiation topography twin chemical etching method |
