| 摘 要： | 假设具有十次旋转对称电子衍射图的Ａｌ－Ｆｅ合金相是由周期性结构产生,利用所谓的Ｃ多面体构造了１个三维周期结构,该结构能作为原子模型来描述Ａｌ－Ｆｅ合金相,该模型的Ｆｏｕｒｉｅｒ变换图较好地符合于相应的电子衍射图。对若干具有十次旋转对称Ｆｏｕｒｉｅｒ变换图的周期性模型也作了简述。

| Abstract: | Electron-diffraction pattern with "tenfold rotational symmetry" of Al-Fe alloyphase is assumed to be produced by periodic structure. One 3D periodic structure is presentedbased on so-called C polyhedra. The structure can be used as atomic model to describethe Al-Fe alloy phase. The Fourier transform patterns of the model are in good agreementwith the corresponding electron-diffraction patterns. Several other models with' tenfold symmetry" Fourier transform patterns have briefly been mentioned. |
