Any further increase or decrease in plane of the X-ray beam could not identify the fracture.

但假如在进一步地加大或减少成角，骨折就难以区别了。

The fractures in all the specimens were clearly visible when the X-ray beam was parallel to the plane of osteotomy.

而当X线光束与骨裂开的平面平行的时候，左右的骨折都可以被鉴别出来。

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.
