本文采用显微结晶、化学浸蚀和光学方法研究了KPB晶体的孪生规律。我们绘制了该晶体的结构投影图和孪晶结构示意图。讨论了晶体孪生的结构成因、形成机制及挛晶结构的稳定性,提出了抑制孪生的关键和途径。
In this paper, the twinning of KPB crystals was studied by means of micro-crystallization, chemical etching and optical methods. We plotted the structure of the crystal projection and twin structure diagram. The formation mechanism of crystal twin, the formation mechanism and the stability of twin structure are discussed. The key and ways to suppress twin are proposed.
