摘　　要：The high resolution transmission electron micrographs(HRTEM) of lamellar crystal of polyethylene(PE) obtained from the melt were successfully obtained by using high resolution electron microscopy,although PE is a relatively irradiation sensitive polymer.The HRTEM images with a clear one-dimensional structure(reported) here were recorded in a transmission electron microscope(TEM) operated at 200 kV.The spacing(between) the fringes was found to be 0.37 nm,which is close to the d-spacing of(200) plane. Micrographs image were processed by using optical filtering methods to improve the signal-to-noise ratio.The high resolution transmission electron micrographs （HRTEM） of lamellar crystal of polyethylene （PE） obtained from the melt were successfully obtained by using high resolution electron microscopy, although PE is a relatively irradiation sensitive polymer.
