Puas hloov pauv tau?
Txawm hais tias kev hloov pauv ntawm ib lub caij mus rau lwm qhov yog lub hauv paus ntawm cov khoom siv hluav taws xob zoo nkauj, nws tseem yog muaj peev xwm hloov ib lub caij mus rau lwm qhov khoom tsim tawm. Kev hloov pauv ntawm ib lub caij mus rau lwm qhov yog cov txheej txheem ntawm kev hloov pauv.
Yuav ua li cas cov txheej txheem kev hloov pauv nuclear tshwm sim hauv particle accelerator?
Nuclear transmutation yog kev hloov pauv ntawm ib qho tshuaj lom neeg lossis isotope mus rau lwm qhov. … Qhov no tshwm sim yog dhau los ntawm cov tshuaj tiv thaiv nuclear uas ib qho sab nraud cuam tshuam nrog lub nucleus, uas tuaj yeem muab los ntawm cov khoom siv accelerator, lossis los ntawm cov xov tooj cua tawg, qhov twg tsis muaj qhov xav tau sab nraud.
