Cov proton - proton saw yog, zoo li kev lwj saw hlau , ib series cov tshuaj tiv thaiv . Cov khoom ntawm ib tshuaj tiv thaiv yog cov khoom pib ntawm cov tom ntej tshuaj tiv thaiv . Muaj ob yam ntawd chains ua los ntawm Hydrogen mus rau Helium nyob rau hauv lub hnub. Ib saw hlau muaj tsib cov tshuaj tiv thaiv , lwm saw hlau muaj rau.

Ib yam li ntawd, qhov txiaj ntsig ntawm cov saw proton proton yog dab tsi?

Cov net tau ntawm no saw hlau yog fusion ntawm plaub protons nyob rau hauv ib tug zoo tib yam helium nucleus (4Nws) nrog lub zog raug tso tawm rau lub hnub qub raws li Einstein qhov sib npaug. Cov khoom hu ua 'neutrinos' () raug tso tawm hauv cov txheej txheem fusion no.

Ib yam li ntawd, cov khoom lag luam ntawm cov proton proton saw yog dab tsi? Lub ntsiab ceg ntawm proton-proton saw.

  • Ob qhov loj-1 isotopes ntawm hydrogen tau txais kev sib xyaw ua ke thiab beta lwj los tsim ib qho positron, neutrino, thiab ib qho loj-2 isotope ntawm hydrogen (deuterium).
  • Lub deuterium reacts nrog lwm qhov loj-1 isotope ntawm hydrogen los tsim Helium-3 thiab gamma-ray.

Yog li ntawd, dab tsi yog tag nrho cov tshuaj tiv thaiv nuclear fusion nyob rau hauv lub hnub luv luv piav qhia txog proton proton saw?

Qhia luv luv txog cov proton – proton chain . Nrog peb Hnub , cov tag nrho cov tshuaj tiv thaiv fusion yog kev hloov ntawm Hydrogen rau Helium. Thawj txoj hauv kev rau qhov hloov dua siab tshiab no yog qhov proton - proton kev sib tham. Cov txheej txheem no pib nrog cov kev fusion ntawm ob Hydrogen nuclei rau hauv ib qho Deuterium nuclei.

Qhov twg cov proton proton saw tshwm sim?

Cov txheej txheem hu ua Proton - Proton (PP) Cov saw , thiab nws ua haujlwm nyob rau hauv lub hnub thiab hnub qub uas zoo sib xws.
