[求助] 有序转变中antiphase domain(APD)和antiphase boundary(APB)的区别?

如题,请问各位,有序转变中antiphase domain(APD)和antiphase boundary(APB)的区别?
    本人在一篇介绍L12和DO22有序转变的文章中看到说:FCC基体向立方L12转变存在四种translational variants (antiphase domains, or APD's),在这些畴界中存在三种界面 (antiphase boundaries, or APB's),错配矢量 1/2<110>;FCC基体向正方DO22转变有四种translational variants,三种antiphase boundaries,错配矢量也是1/2<110>,英文原文如下:
    For the cubic to cubic, fee — Ll2 transition, four translational variants (antiphase domains, or APD's) of the Ll2 are possible. Three types of interfaces can occur between these domains (antiphase boundaries, or APB's) having 1/2(110)-type displacement vectors. For the cubic to tetragonal, fee — DO22 transition, within each rotational domain of the tetragonal DO22 four translational APD's (with three types of APB's) are possible. Displacement vectors of the APD's are the same as for the Ll2 APD's (in fee coordinates). In the tetragonal coordinates of the DO22 the vectors are l/2[110], 1/2[10 j]t, and l/2[01 {],. While each of the Ll2 APB's can be identified by dark-field imaging with different superlattice reflections, the 1/2(10j^-type interfaces of the DO22 cannot be distinguished from each other (the reflection conditions for the IA/mmm spacegroup of the DO22 forbid hkl with h + k + I = odd).
    文中提到的APD、ADB、displacement vector是属于什么概念?请各位指教!
    本人金币有限,请见谅O(∩_∩)O~

你可以看看一本《晶体学中的对称群》中的第十章,相变中的群与子群关系
