Alpha , Beta , Gamma Kev sib xyaw
Alpha particles muaj cov nqi zoo, beta particles nqa tus nqi tsis zoo, thiab gamma rays yog nruab nrab. Alpha particles muaj loj dua beta cov khoom
Ntxiv mus, qhov twg hnyav dua alpha lossis beta hais?
Cov alpha particle yog cov hnyav tshaj plaws . Nws yog tsim thaum lub hnyav tshaj plaws cov khoom lwj. Alpha thiab beta rays tsis yog nthwv dej. Cov alpha particle yog helium atom thiab muaj ob lub neutrons thiab ob protons.
Ib tug kuj tseem nug, Alpha Beta Gamma yog dab tsi? Alpha hluav taws xob yog lub npe rau emission ntawm ib alpha Qhov tseeb yog ib qho helium nuclei, beta hluav taws xob yog qhov emission ntawm electrons los yog positrons, thiab gamma hluav taws xob yog lub sij hawm siv rau emission ntawm lub zog photons.
Yog li, qhov txawv ntawm gamma alpha thiab beta hluav taws xob yog dab tsi?
Qhov sib txawv ntawm Alpha , Beta thiab Gamma xov tooj cua lwj tuaj yeem sau tau raws li hauv qab no: Alpha lwj tsim cov khoom tshiab nrog ob tsawg dua protons thiab ob tsawg dua neutrons; Gamma hluav taws xob muaj lub zog nkag siab tshaj plaws, Beta lwj mus qhov thib ob, alpha lwj kawg.
Vim li cas Alpha Beta thiab Gamma thiaj li muaj peev xwm nkag mus sib txawv?
Txhua hom hluav taws xob muaj ib muaj peev xwm sib txawv rau nkag mus cov ntaub ntawv. Cov alpha hluav taws xob hloov ntau lub zog rau ib qho absorber dua beta los yog gamma hluav taws xob. Alpha hluav taws xob yog absorbed los ntawm lub thickness ntawm daim tawv nqaij los yog los ntawm ob peb centimeters ntawm huab cua. Beta hluav taws xob yog ntau nkag mus tshaj alpha hluav taws xob.

Qhov twg los thawj qhov ntev lossis qhov dav lossis qhov siab?
Dab tsi los ua ntej? Graphics 'kev lag luam tus qauv yog dav los ntawm qhov siab (dav x qhov siab). Txhais tau hais tias thaum koj sau koj qhov ntsuas, koj sau lawv los ntawm koj qhov kev xav, pib nrog qhov dav. Qhov ntawd tseem ceeb
Puas yog qhov hnyav lossis qhov hnyav?
Qhov loj ntawm ib yam khoom yog ib qho kev ntsuas ntawm cov khoom inertial khoom, los yog tus nqi ntawm cov khoom nws muaj. Qhov hnyav ntawm ib yam khoom yog ib qho kev ntsuas ntawm lub zog ntawm qhov khoom los ntawm lub ntiajteb txawj nqus, lossis lub zog xav tau los txhawb nws. Qhov rub ntawm lub ntiajteb txawj nqus ntawm lub ntiaj teb muab ib yam khoom ib tug downward acceleration ntawm txog 9.8 m / s2
Qhov twg yog qhov tseeb dua qhov hloov pauv pipette lossis ntsuas pipette?
Kawm tiav pipettes yog tsawg dua li volumetric pipettes. Mohr kawm tiav pipettes, uas yog qee zaum hu ua "drain out pipettes", tau cim nrog xoom thaum pib ntawm lawv qhov kawg conical, thaum Serological kawm tiav pipettes, tseem hu ua "tsov tawm pipettes", tsis txhob tso cov cim xoom
Qhov txawv ntawm qhov hnyav thiab qhov hnyav yog dab tsi?
Raws li lub npe qhov sib txawv ntawm qhov hnyav thiab hnyav yog tias lub nra yog lub nra; qhov hnyav yuav tsum tau nqa thaum qhov hnyav yog lub zog ntawm ib qho khoom vim qhov kev sib tw ntawm nws thiab lub ntiaj teb (lossis yam khoom siv astronomical nws feem ntau cuam tshuam los ntawm)
Qhov twg muaj zog nkag tau ntau dua alpha lossis beta?
Alpha hluav taws xob yog absorbed los ntawm lub thickness ntawm daim tawv nqaij los yog los ntawm ob peb centimeters ntawm huab cua. Beta radiation yog nkag mus ntau dua li alpha hluav taws xob. Nws tuaj yeem hla ntawm daim tawv nqaij, tab sis nws yog absorbed los ntawm ob peb centimeters ntawm lub cev nqaij daim tawv los yog ob peb millimeters ntawm txhuas
