A beta particle yog li 8,000 npaug me dua li alpha particle -- thiab qhov ntawd yog qhov ua rau lawv ntau dua txaus ntshai . Lawv qhov me me tso cai rau lawv nkag mus rau khaub ncaws thiab tawv nqaij. Kev raug sab nraud tuaj yeem ua rau kub hnyiab thiab cov ntaub so ntswg puas, nrog rau lwm cov tsos mob ntawm hluav taws xob mob.
Xav txog qhov no, lub xov tooj cua twg yog qhov txaus ntshai tshaj plaws rau tib neeg?
Gamma
Qhov thib ob, alpha hluav taws xob cuam tshuam rau lub cev li cas? Alpha hais tsis muaj lub zog kom nkag mus txawm tias txheej txheej ntawm daim tawv nqaij, yog li raug rau sab nraud lub cev tsis yog ib qho kev txhawj xeeb loj. Yog alpha - emitters yog nqus tau, nqos, los yog nkag mus rau hauv lub cev los ntawm kev txiav, lub alpha hais ua tau kev puas tsuaj cov ntaub so ntswg nyob.
Tib neeg kuj nug, alpha lossis beta hais puas txaus ntshai?
alpha hluav taws xob yog cov txaus ntshai tshaj plaws vim nws yooj yim absorbed los ntawm hlwb. beta thiab gamma hluav taws xob tsis yog li txaus ntshai vim tias lawv tsis tshua muaj peev xwm nqus tau los ntawm lub cell thiab feem ntau yuav dhau los ntawm nws.
Dab tsi yog qhov phom sij ntawm hluav taws xob?
Tshaj tawm rau qib siab heev ntawm hluav taws xob , xws li nyob ze rau qhov tawg atomic, tuaj yeem ua rau mob hnyav xws li tawv nqaij kub hnyiab thiab mob hnyav. hluav taws xob syndrome (" hluav taws xob mob"). Nws kuj tuaj yeem ua rau muaj kev noj qab haus huv mus ntev xws li mob qog noj ntshav thiab kab mob plawv.

Puas yog tib neeg tsim los ntawm qhov teeb meem?
Tau kawg lawv. Yog tias tib neeg tsis tsim teeb meem, tab sis antimatter, koj yuav tsis muaj nyob tam sim no. Thaum kawg, peb tsis tuaj yeem txiav txim siab tiag tiag seb peb puas yog qhov teeb meem lossis tsis muaj teeb meem, tab sis raws li cov ntsiab lus tam sim no rau ob nqe lus, tib neeg yog qhov tseem ceeb
Muaj pes tsawg txoj kev daws teeb meem tib kab muaj?
Cov kab ke ntawm kab sib npaug tuaj yeem tsuas muaj 0, 1, lossis ib qho kev daws teeb meem tsis kawg. Ob kab no tsis tuaj yeem hla ob zaug. Cov lus teb raug yog tias qhov system muaj ib qho kev daws teeb meem
Puas yog kev daws teeb meem yog tshuaj lom neeg?
Raws li UPAC 'kev daws teeb meem yog ib qho kev sib cuam tshuam ntawm cov kuab tshuaj nrog cov kuab tshuaj, uas ua rau kom muaj kev ruaj khov ntawm cov hom solute hauv cov tshuaj.' Hauv cov ntsiab lus, kev daws teeb meem tsis yog tshuaj lom neeg cov tshuaj tiv thaiv, thiab txuas ntxiv qhov kev sib cais ntawm cov ntsev tsis yog tshuaj lom neeg, tab sis kev hloov theem
Dab tsi yog cov particles muaj teeb meem?
Cov khoom yog tsim los ntawm atoms, thiab atoms yog tsim los ntawm protons, neutrons, thiab electrons. Txhua yam hauv ntiaj teb no yog tsim los ntawm qhov teeb meem. Txawm hais tias qhov teeb meem muaj nyob hauv ntau hom ntawv, txhua daim ntawv yog tsim los ntawm tib lub hauv paus ntsiab lus: cov khoom me me hu ua atoms
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
