Particle thiab antiparticle khub yog tsim los ntawm cov khoom loj ntawm lub zog . Qhov no yog qhov tshwm sim ntawm Einstein lub npe nrov sib npaug ntawm huab hwm coj thiab lub zog, E=mc2. … Hloov pauv, thaum ib qho particle ntsib ib qho antiparticle, lawv rhuav tshem mus rau hauv lub zog tawg heev.
cov tshuaj tiv thaiv tuaj qhov twg?
Antiparticles yog tsim naturally nyob rau hauv qhov chaw thiab nyob rau ntau lub hnub los yog hnub qub nyob rau hauv lub ntiaj teb no vim yog kev sib tsoo ntawm cov khoom siv hluav taws xob siab. High-zog cosmic rays los ntawm qhov chaw tawm tsam atoms nyob rau hauv cov huab cua thiab tsim antiparticles. Lawv sib tsoo sai sai nrog cov khoom teeb meem thiab rhuav tshem.
Postitron tsim li cas?
Positrons yog tsim thaum kev lwj ntawm nuclides uas muaj ntau tshaj ntawm protons hauv lawv cov nucleus piv rau cov neutrons. Thaum kev lwj tshwm sim, cov xov tooj cua no tawm positron thiab neutrino.
Yuav ua li cas yog antimatter tsim?
Ua ntej, koj xav tau lub tshuab nqus tsev zoo heev kom cov tshuaj tiv thaiv tsis txhob cuam tshuam rau hauv atom stray hauv huab cua. Tom qab ntawd koj yuav tsum khaws nws kom deb ntawm ob sab ntawm koj lub thawv vim tias cov no tseem ua rau muaj teeb meem. Txoj kev daws yog ' lub raj mis sib nqus'uas siv hluav taws xob thiab sib nqus teb los kaw cov tshuaj tiv thaiv.
Puas muaj antimatter lawm?
Rau yav dhau los 50 xyoo thiab ntau dua, cov chaw sim xws li CERN tau tsim cov tshuaj tiv thaiv ib txwm muaj, thiab xyoo 1995 CERN tau los ua thawj lub chaw kuaj mob tsimanti-atoms artificially. Tab sis tsis muaj leej twg tau tsim cov tshuaj tiv thaiv yam tsis muajkuj tau txais cov khoom sib xws.
