Lub Rutherford Kub Foil kev sim tua feeb hais ntawm ib daim ntawv nyias kub . Nws tau pom tias ib feem me me ntawm cov khoom tau deflected, thaum feem ntau dhau los ntawm daim ntawv. Qhov no ua rau Rutherford xaus lus tias qhov loj ntawm ib lub atom yog concentrated ntawm nws qhov chaw.
Yog li ntawd, qhov kev sim ntawm cov ntawv ci kub ua haujlwm li cas?
Lesson Summary Rutherford's kub foil sim qhia tau hais tias cov atoms feem ntau yog qhov chaw khoob, nrog rau cov nqi zoo concentrated hauv lub nucleus. Nws paub qhov no vim hais tias feem ntau ntawm cov alpha hais tau ncaj qha los ntawm daim ntawv ci , tsuas yog ob peb deflected ntawm cov ces kaum loj.
Kuj Paub, vim li cas Rutherford cov tub ntxhais kawm xav tsis thoob los ntawm cov txiaj ntsig ntawm kev sim cov ntawv nyiaj kub? Rutherford nrhiav pom cov proton, thiab nws kuj pom tias lub atom yog qhov chaw khoob. Nws pom tias ib tug beam ntawm alpha hais yog tawg ri niab rov qab qhov twg nws tuaj los ntawm kub atoms, thiab, txij li nws yog paub tias alpha hais tau positive, nws yog deduced tias muaj yog ib tug ntom zoo core nyob rau hauv lub nucleus.
Yog li ntawd, dab tsi yog qhov xav tau ntawm cov ntawv ci kub sim?
Cov xav tau ntawm kev sim yog tias tag nrho cov alpha hais yuav dhau los ntawm ntawv ci yam tsawg kawg deflection. Cov no tshwm sim muab lub tswv yim tias lub atom muaj feem ntau ntawm qhov chaw khoob thiab feem ntau ntawm cov huab hwm coj thiab zoo ntawm lub atom yog nyob rau hauv ib tug me me core hu ua lub nucleus.
Vim li cas nws thiaj li hu ua cov ntawv xov xwm kub?
Vim nws yog lub npe ntawm lub kev sim Rutherford tau nrhiav cov qauv atomic tshiab. Nws siv nyias ntawv ci thiab foob nws nrog alpha hais. Vim nws yog lub npe ntawm lub kev sim Rutherford tau nrhiav cov qauv atomic tshiab. Nws siv nyias ntawv ci thiab foob nws nrog alpha hais.

Vim li cas qhov kev tawg ntawm daim ntawv thiab hlawv cov ntawv suav tias yog ob hom kev hloov pauv?
Tearing ntawm daim ntawv yog ib qho kev hloov ntawm lub cev vim hais tias thaum daim ntawv torn tsuas yog cov tsos ntawm daim ntawv hloov thiab tsis muaj cov khoom tshiab tsim. tearing ntawm daim ntawv yog ib qho kev hloov ntawm lub cev vim nws tseem zoo li qub tab sis qhov kub ntawm daim ntawv yog ib qho tshuaj hloov vim nws hloov mus rau hauv tshauv
Qhov kub ntawm qhov hluav taws kub kub li cas?
Feem ntau hom ntoo yuav pib combusting ntawm li 300 degrees Celsius. Cov pa roj hlawv thiab nce qhov kub ntawm cov ntoo mus txog 600 degrees Celsius (1,112 degrees Fahrenheit). Thaum cov ntoo tso tawm tag nrho nws cov gases, nws tawm charcoal thiab tshauv
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Cov yam ntxwv ntawm cov ntaub ntawv twg yog qhov ntsuas ntawm tus nqi uas cov ntaub ntawv muaj nuj nqis heev?
Variation: Ib qho kev ntsuas ntawm tus nqi uas cov ntaub ntawv muaj nuj nqis sib txawv. ? Kev faib tawm: Cov xwm txheej lossis cov duab ntawm kev sib kis ntawm cov ntaub ntawv hla ntau qhov tseem ceeb (xws li tswb-puab). ? Outliers: Cov qauv piv txwv uas nyob deb heev ntawm feem ntau ntawm lwm cov qauv nqi
Vim li cas nws tseem ceeb uas yuav tsum rov ua qhov kev sim thiab sim cov kev xav hauv ntau txoj kev?
Nws yog ib qho tseem ceeb rau cov kws tshawb fawb kom rov sim dua thaum ua qhov kev sim vim tias qhov kev txiav txim siab yuav tsum raug lees paub. Muaj tseeb vim tias cov txiaj ntsig ntawm txhua qhov kev xeem yuav tsum zoo sib xws. Lwm cov kws tshawb fawb yuav tsum tuaj yeem rov ua koj qhov kev sim thiab tau txais cov txiaj ntsig zoo sib xws. Tib txoj hauv kev los ntsuas qhov kev xav yog ua qhov kev sim
