Acoording to the crystal symmetry, diffraction geometry and the diffraction laws, the complicated divergent beam X-ray diffraction has been studied.

根据晶体的对称性、衍射几何和衍射规律，研究了复杂的发散X射线晶体衍射。

Instead, a single wavelength can be selected to produce the X-ray equivalent of a pure-colour beam of light.

事实上单独某一个波长的射线就可以产生好象一束单色光一样的纯净的伦琴射线。

The researchers then narrowed down the X-ray beam so that it was just a tenth of a millimetre across and found that the fractal-like regions occurred only where the beam struck the sample.

研究人员随后将X射线的光束收窄，使其只有十分之一毫米宽，这时他们发现，碎片形的区域只出现在射线照射的地方。

The specimen is then rotated on a mechanised platform as it is exposed to the X-ray beam, in order to build up a three-dimensional picture.
