diffraction figure造句

Let us consider the diffraction figure obtained with a single crystal, on a plane that is perpendicular to the beam, e . g.
If the parameters of the optics are known ( especially the distance between the crystal and the photographic film ), it is possible to build the stereographic diagram from the diffraction diagram, i . e . to transform the diffraction figure into a pole figure.
It's difficult to find diffraction figure in a sentence. 用diffraction figure造句挺难的
