| 摘 要： | 目的研究准晶中的位错弹性理论. 方法通过将位错分解为刃型和螺型分量,该位错引起的整个弹性场可由两个分量所引起的弹性场叠加得到. 结果与结论获得了平行于准周期轴的直位错的弹性场及两个平行的直螺型位错之间的广义Peach-Koehler力.

| Abstract: | Aim To study dislocation elasticity theory in quasicrystals. Methods A dislocation was separated into pure edge part and pure screw part and their superposition was used to find the elastic field. Results and Conclusion The elastic solution of a straight dislocation parallel to the quasiperiodic axis in 1D hexagonal quasicrystals was obtained and the generalized Peach Koehler force on a dislocation in quasicrystals was given. |

| Keywords: | hexagonal quasicrystal dislocation elastic field Peach-Koehler force |
