摘　　要：孪晶的表征方法有透射电子衍射以及电子背散衍射(Electron Backscattered Diffraction,EBSD),目前极少有一个衍射花样标准供参照.本文建立了面心立方(Face-Centered Cubic,FCC)和体心立方(Body-Centered Cubic,BCC)孪晶与TEM衍射花样以及EBSD花样之间的数理关系,给出了它们的计算衍射花样,为孪晶结构表征提供了依据.Characterization methods of twin crystal include transmission electron diffraction and electron backscattered diffraction(EBSD).Currently,there is a lack of a standard diffraction pattern for reference.It is established the mathematical relationship between face-centered cubic(FCC)and body-centered cubic(BCC)twins and the diffraction patterns of transmission electron diffraction and EBSD.The calculated diffraction patterns are provided,whitch offers a basis for the characterization of twin structures.
