This calibration is usually carried out by employing a double exposure technique in which the diffraction pattern and electron image of a crystal of molybdenum trioxide are successively exposed 这个标准通常利用使得衍射模型和一个三氧化钼的结晶体的电子成像成功展现的双投照技术来执行。
2.
This inversion will lead to an additional 1800 relative rotation between the diffraction pattern and micrograph that would not be detectable in the double exposure technique illustrated in fig . l . 3 图表1 . 3所示的双曝光技术中对于衍射模型和显微图并没有表示出来，这个倒置，就在衍射模型和显微图之间形成了一个额外的1800相关旋转。
