Cov txiaj ntsig ntawm kev txhais lus tau hais tias yog vim muaj cov khoom tsim positron hauv kev rhuav tshem cov xwm txheej ntawm cov teeb meem tsaus ntuj loj heev. Cosmic ray antiprotons kuj tseem muaj lub zog nruab nrab ntau dua li lawv cov khoom sib xws (protons).
Daim duab ntawm cosmic ray twg muaj lub zog siab tshaj?
PeVatrons tau ntseeg tias yog qhov chaw muaj zog tshaj plaws ntawm cosmic rays hauv peb lub galaxy, thiab lawv qhov kev txheeb xyuas tseeb tau dhau los ua qhov nyuaj. PeVatrons ceev cov protons rau petaelectronvolts (PeVs), ib qho loj ntawm lub zog kinetic muaj peev xwm ntawm slinging subatomic hais teeb-xyoo thoob plaws galaxy.
Lub zog npaum li cas hauv lub cosmic ray?
Lub zog ntawm thawj cosmic rays muaj los ntawm ncig 1 GeV - lub zog ntawm cov khoom siv me me - kom ntau li 10 8TeV, deb tshaj qhov nqaj zog ntawm Loj Hadron Collider.
Dab tsi yog qhov hluav taws xob siab tshaj plaws?
Gamma-rays yog daim ntawv muaj zog tshaj plaws ntawm hluav taws xob hluav taws xob, nrog ntau dua 10,000 npaug zog dua li pom lub teeb photons. Yog tias koj pom Gamma-rays, lub ntuj hmo ntuj yuav zoo li txawv txawv thiab tsis paub.
Yuav ua li cas lub cosmic rays siv rau lub zog?
Cov xwm txheej tseem ceeb tshaj plaws hauv qhov chaw yog hnub ci cua thiab galactic cosmic rays. Cov xwm txheej no ntws tawm cov khoom muaj zog heev xws li proton, electron, alphaparticle thiab HZE. Lub zog muaj los ntawm proton thiab electron feem ntau yog nruab nrab ntawm 1.5 thiab 10 keV. Lub zog no siv tau los tsim hluav taws xob.

Puas muaj cov kua qaub uas muaj zog ionised hauv dej?
(siab dua) Cov kua qaub muaj zog ua tiav ionise hauv dej. Lawv rhuav tshem tag nrho los tsim kom muaj cov ntsiab lus siab ntawm hydrogen ions hauv cov tshuaj. Vim li cas cov kua qaub muaj zog ionize tag nrho hauv dej? Ib qho kua qaub lossis lub hauv paus lub zog hais txog nws qib ntawm ionization.
Puas uv rays muaj zog dua rau hnub huab cua?
Tseeb, huab feem ntau zoo dua ntawm kev thaiv lub teeb pom kev zoo dua li UV. ultraviolet hluav taws xob tuaj yeem txhim kho tau zoo tshaj qhov tseeb-ntev qhov tseem ceeb ntawm hnub huab, tshwj xeeb tshaj yog thaum muaj huab cua cirrus thiab cumulus saum ntuj.
Hauv kev ntsuas qhov muaj zog thiab qhov tsis muaj zog?
Kev ntsuas kev ua tau zoo thiab qhov tsis muaj zog Pab pawg. Ua haujlwm zoo nrog cov neeg siv khoom, cov thawj coj, cov neeg ua haujlwm, thiab lwm tus yog qhov kev txawj ntse. … Adaptability. Koj cov neeg ua haujlwm yuav tsum muaj peev xwm ua tiav lawv txoj haujlwm hauv cov xwm txheej hloov sai.
Nyob rau hauv kev ua kom lub cev tsis muaj zog uas tsis muaj qhov xav tau?
Nyob hauv cov txheej txheem kev kawm hu ua classical conditioning, unconditioned stimulus (UCS) is one uas unconditionally, lawm, thiab cia li ua rau teb. Hauv lwm lo lus, cov lus teb tshwm sim yam tsis muaj kev kawm ua ntej. Qhov kev xav tau thiab tsis muaj kev cia siab yog dab tsi?
Puas yog qhov muaj zog tshaj qhov tsis muaj zog hauv sparta?
Sparta ua phem heev thiab txhua yam lawv xav txog yog muaj tub rog muaj zog tshaj plaws. Qhov tsis muaj zog ntawm Sparta tshaj qhov muaj zog vim Spartans tsis muaj kev kawm, cov tub hluas raug tshem tawm ntawm lawv tsev neeg thaum tseem hluas, thiab lawv raug tsim txom heev.
