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。

Then they brought the sample back to room temperature and exposed it to an X-ray beam from the facility while using a CCD detector to record the X-rays reflected from the surface of the sample.

然后他们将样品重置于室温状态，并使其接受X射线照射，同时使用CCD检测器来记录从样品表面反射回的X射线。

The nanoprobe excites the sample with a strongly focused X-ray beam and collects the characteristic fluorescence signal that is re-emitted.

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.
