【Abstract】 This paper presents the image measurement and analysis method with computed tom ography for polymer in solid conveying. It utilizes the knowledge of nuclear phy sics, photo_electricity, polymer physics, computer technology a nd mathematics synthetically, the polymer morphology in solid co nveying can be visually obtained by the interaction of polymer atom or po lymer chain and the photon beam caused by γ_ray, in which the photoemission, Compton effect and electron pair effect will be generated. The experimental res ults 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 polym er in solid conveying.更多还原
