采用晶面的极射赤面投影方法,从理论上绘制了一套不同立方晶体的理论电子通道图。为了迅速注释从实验所得的立方晶体的电子通道花样,利用上述理想电子通道图的数据制成图表,可以大大节约注释时间。误差分析表明,本注释方法不但适用于晶带轴平行于扫描电镜光轴的情况,而且适用于晶带轴倾斜于光轴的情况。 Using the polar plane red-plane projection method of crystal plane, a set of theoretical electronic channel diagrams of different cubic crystals are theoretically drawn. In order to quickly annotate the electron channel patterns of the cubic crystals obtained from the experiments, it is possible to significantly reduce the annotation time by using the data of the ideal electron channel map as described above. Error analysis shows that the method of this note applies not only to the case where the belt axis is parallel to the optical axis of the SEM, but also to the case where the belt axis is inclined to the optical axis.
