Positron vs Proton
Proton yog ib qho atomic particle uas tau ntsib hauv kev kawm ntawm lub atom. Positron yog ib qho tshuaj tiv thaiv kab mob, uas qhia cov yam ntxwv tshwj xeeb rau cov tshuaj tiv thaiv. Ob leeg ntawm cov khoom no ua lub luag haujlwm tseem ceeb hauv kev piav qhia ntawm lub atom. Txoj kev kawm ntawm proton, positron thiab lwm yam sub atomic hais yog dav siv nyob rau hauv xws li physics, nuclear science thiab txawm chemistry. Hauv tsab xov xwm no, peb yuav los sib piv thiab sib piv cov proton thiab positron yog dab tsi, lawv cov ntsiab lus, cov khoom ntawm proton thiab positron, kev sib cuam tshuam ntawm proton thiab positron nrog rau lwm yam teeb meem thiab teb, qhov zoo sib xws ntawm proton thiab positron, thiab thaum kawg qhov txawv ntawm proton thiab positron.
YProton yog dab tsi?
Proton yog ib qho atomic particle uas tau pom nyob rau hauv lub nucleus ntawm lub atom. Lub proton yog ib tug zoo nqi particle. Qhov loj ntawm cov proton yog 1.673 x 10 -27 kg. Tus nqi ntawm cov proton yog qhov tsawg tshaj plaws ntawm cov nqi them tuaj yeem tau txais. Qhov no tseem hu ua tus nqi qis. Tus nqi no yog sib npaug rau 1.602 x 10-19 Coulomb. Txij li thaum tus nqi ntawm cov proton yog qhov tsawg tshaj plaws ntawm tus nqi ntawm cov khoom tuaj yeem tau txais, nws yog qhov pom tseeb tias ib qho ntawm cov nqi uas peb ntsib hauv lub neej niaj hnub yog qhov sib npaug ntawm cov nqi ntawm cov proton. Lub proton muaj ob lub nce quarks thiab ib tug down quark. Quarks yog lub hauv paus sub atomic hais, tab sis lawv tsis tuaj yeem raug cais tawm. Cov proton yog ib qho khoom ruaj khov heev. Isolated proton muaj nyob rau hauv cov xwm txheej xws li ionized Hydrogen thiab Hydrogen plasma. Cov proton muaj qhov sib npaug ntawm ½. Lub proton ntog rau hauv sub atomic particle tsev neeg ntawm baryons. Tag nrho cov nuclei, tshwj tsis yog Hydrogen nucleus, muaj ob lossis ntau dua protons. Cov protons nrog rau cov neutrons tsim cov nucleus. Proton - proton repulsion rog yog sib npaug los ntawm kev sib cuam tshuam zoo. Kev sib cuam tshuam muaj zog thiab hluav taws xob hluav taws xob yog ob ntawm plaub lub zog ntawm qhov xwm txheej.
Positron yog dab tsi?
Positron yog ib qho tshuaj tiv thaiv. Nws tseem hu ua antielectron vim tias positron yog antiparticle ntawm electron. Lub positron feem ntau yog cim los ntawm lub cim e+ Lub positron kuj muaj tus nqi qis ntawm +1.602 x 10-19 Coulomb, whereas lub electron muaj cov tib tus nqi tsis zoo. Lub positron muaj tib lub loj li cov electron, uas yog 9.109 x 10 -31kilogram. Lub positron muaj qhov tig ntawm 1/2. Txij li thaum lub positron yog lub antimatter counterpart (los yog antiparticle) ntawm lub electron, yog hais tias ib tug tsawg zog electron thiab ib tug tsawg zog positron collides nws yuav rhuav tshem tag nrho cov loj thiab hloov mus rau lub zog nyob rau hauv daim ntawv ntawm ob photons. Qhov tshwm sim no hu ua teeb meem - antimatter annihilation.
Qhov txawv ntawm Proton thiab Positron yog dab tsi?
• Proton yog ib feem ntawm cov teeb meem ib txwm muaj, uas peb paub. Positron yog ib feem ntawm antimatter, uas peb tsis saib hauv lub neej txhua hnub.
• Cov proton muaj qhov loj ntawm 1.673 × 10 -27 kg, whereas lub positron muaj qhov loj ntawm 9.109 × 10 -31Kg.
• Cov proton yog cov khoom ruaj khov heev hauv cov chaw kuaj ib txwm muaj, tab sis cov positron yog ib qho tsis ruaj khov heev nyob rau hauv ib puag ncig zoo li no.
