Hauv nuclear physics, astrophysics, thiab reactor ua haujlwm, polyethylene yog siv los ua diffuser los ntsuas neutrons. Pab txhawb rau kev kawm ntawm nuclear physics.
Ib hom polyethylene (PE) yas, lub hnab yooj yim peb feem ntau hais yog polyethylene (PE). Polyethylene yog cov polymer uas yooj yim tshaj plaws thiab feem ntau siv cov khoom siv polymer. Nws yog tsim los ntawm kev rov ua dua -CH2- units txuas ua ke. Polyethylene yog tsim los ntawm ntxiv polymerization ntawm ethylene (CH2=CH2).
