英文摘要	Ultrathin sections of polyacrylonitrile (pan) fibre samples in the stabilization and carbonization stages were studied using high-resolution transmission electron microscopy. supplementary analyses by the fourier transform infrared, x-ray diffraction, thermogravimetry mass spectroscopy and elemental analysishave also been done. results showed that the pan fibres contained nanosized crystallites embedded in a continuous amorphous matrix. amorphous onion-like spherical structures were also observed and their structural evolution was investigated. during the stabilization and carbonization process, the outer layers of the onion-like spheres gradually changed from an orderly layered structure into a disordered, dense structure due to cyclization and cross-linking reaction. during carbonization, the onion-like spheres became more dense and compact due to the merging of the ring structures. after carbonization, the onion-like spheres in the pan fibres eventually turned into dense and amorphous domains of carbon fibres.
