摘要：
The general decomposition formula was established for the structures of symmetrical tilt grain boundaries with the tilt axis of < 001 >. By investigating the underlying mathematical structure, we propose a novel algorithm to obtain the arrangement of structural units for any misorientation angle of the boundary with an arbitrary precision due to the Farey sequence.
