%X A method has been advanced to determine precisely the orientation difference of the crystals between low-angle boundaries and sub-boundaries of high purity Al by convergent beam electron diffraction studies. The results show that the ones of low-angle and sub-boundaries are 1.55±0.051° and 0.32+0.037° respectively, as well as the curved angle of the crystal by single edge dislocation is 0.22±0.036°. The accuracy and error of the method have been analysed. Some problems concerning their structure of dislocation network and type were also discussed.
