Abstract: This paper presents the image measurement and analysis method with computed tomography for polymer in solid conveying．It utilizes the knowledge of nuclear physics‚photo-electricity‚polymer physics‚computer technology and mathematics synthetically‚the polymer morphology in solid conveying can be visually obtained by the interaction of polymer atom or polymer chain and the photon beam caused by γ-ray‚in which the photoemission‚Compton effect and electron pair effect will be generated．The experimental results indicate the method can not only measure the deformation and morphology of polymer in the way of non-open‚non-destroy and on-line‚but also find the relationship between the morphology and the mechanical properties of polymer in solid conveying．

Key words: image measurement, computed tomography, extrusion theory, polymer morphology
