According to the mechanical and electrical continuity conditions, the transfer matrix between two consecutive unit cells is obtained. 根据界面上力电连续条件,推导了结构中相邻单胞间的传递矩阵。
The regularity in these microstructures offers useful means of characterising these materials through the use of unit cells. 通过建立胞元,这些微观结构里的规律提供了有效的途径来表征这些材料。
Deriving the smallest primitive unit cells, necessary to describe the translational periodicity of a crystal structure, is the first step toward choosing the correct space group. 导出反映晶体结构周期的最小素单胞是正确判断空间群的第一步,其中以还原单胞的选择最为理想。
The defined unit cells have the brick shape which height is equal to the braiding pitch, and oriented in the same reference coordinate as the composites. 该单胞模型为一六面体形状,其取向平行于预制件的表面,且高为编织花节长。
For different unit cells, the truncation criterion of infinite series is discussed. 针对不同形状的阵单元,本文还讨论了三维谱域法中无穷级数的截断准则。
