利用背散射电子衍射取向成像技术，定量分析了具有初始织构的AZ31镁合金平面应变压缩时的孪生过程。
2·Countries with taller women have higher rates of twinning compared to countries with shorter women.
与女性平均身高较低的国家相比，在女性平均身高较高的国家孪生的发生率也较高。
3·This paper investigated the law of KPB crystal twinning using microcrystallography, chemical etching and optical method.
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。
4·Tensile ductility of lamellar microstructure is higher than that of equiaxed one at 20 K. Its deformation process consists of twinning and slipping.
低温下粗大的片状组织比等轴组织具有更高的拉伸延性，且合金的变形是由孪生变形和滑移变形共同作用的结果。
5·Identical twinning can begin only inside the Fallopian tube.
同卵孪生可能只在输卵管内开始发育。
