Thaum koj paub lub luminosity thiab kub (lossis xim) ntawm lub hnub qub, koj tuaj yeem npaj lub hnub qub raws li qhov taw qhia ntawm H-R daim duab. Teeb lub luminosity ntawm y-axis nrog cov hnub qub ci dua mus rau saum.
Ntawm no, ua li cas koj npaj lub hnub qub ntawm daim duab HR?
Hauv ib Daim duab H-R lub luminosity los yog lub zog tso zis ntawm a hnub qub yog plotted rau ntawm ntsug axis. Qhov no tuaj yeem raug nthuav tawm raws li qhov piv ntawm cov lub hnub qub luminosity rau lub hnub; L*/Lhnub. Astronomers kuj siv keeb kwm lub tswv yim ntawm qhov loj me raws li kev ntsuas ntawm a lub hnub qub luminosity.
Tsis tas li ntawd, dab tsi yog qhov tseem ceeb ntawm lub hnub qub Cov cuab yeej tseem ceeb ntawm lub hnub qub txiav txim siab qhov twg nws nyob ntawm qhov sib lawv liag? A lub hnub qub loj yuav txiav txim siab qhov twg nws nyob ntawm lub ntsiab ntu . Qhov loj tshaj plaws hnub qub nyob rau sab laug kawg thaum qhov qis tshaj plaws hnub qub yog nyob rau sab xis kawg.
Ib yam li ntawd, koj tuaj yeem nug, ntawm qhov twg ntawm HR daim duab koj yuav npaj cov hnub qub no?
Cov duab kos , npe Hertzsprung-Russell los yog HR daim duab , zaj luminosity nyob rau hauv hnub ci units ntawm Y axis thiab stellar kub ntawm X axis, raws li qhia hauv qab no. Nco ntsoov tias cov nplai tsis yog linear. Kub hnub qub nyob sab laug tes sab ntawm daim duab , txias hnub qub sab tes xis sab.
Daim duab HR qhia dab tsi?
Cov Hertzsprung-Russell Daim duab yog ib lub cuab yeej graphical uas cov neeg astronomers siv los faib cov hnub qub raws li lawv cov luminosity, spectral hom, xim, kub thiab evolutionary theem. Cov hnub qub nyob rau theem ruaj khov ntawm hydrogen hlawv nyob rau ntawm Main Sequence raws li lawv qhov loj.

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
Thaum muab piv cov qauv sau rau ib tus neeg raug liam cov ntaub ntawv lub hnub nyoog sib txawv ntawm cov ntaub ntawv yuav tsum tsis pub tshaj kaum ob lub hlis?
Thaum piv cov qauv sau rau tus neeg raug liam? cov ntaub ntawv, lub hnub nyoog sib txawv ntawm cov ntaub ntawv yuav tsum tsis pub ntau tshaj rau rau kaum ob lub hlis. Tus lej txaus ntawm tus qauv yog qhov tseem ceeb rau kev txiav txim siab qhov tshwm sim ntawm kev sib piv
Cov ntaub ntawv dab tsi xav tau rau daim ntawv chromatography?
Daim Ntawv Chromatography ua haujlwm li cas? dej soluble cwj mem los yog cov cim ntawm ntau hom lossis xim. strips ntawm daim ntawv phuam. dej. rubb cawv. ntsia thawv polish remover. straw los yog xaum los yog cwj mem. khob. daim kab xev
Dab tsi yog cov cuab yeej lossis cov ntaub ntawv uas tus Kws Tshawb Fawb xav tau los txheeb xyuas cov ntaub ntawv nug?
Cov ntaub ntawv raug nug hauv chav kuaj ua txhaum cai yog nruab nrog lub tshuab ntsuas ntsuas, ntsuas cov duab digital, infrared thiab ultraviolet lub teeb ci, cov cuab yeej tshuaj ntsuam video thiab cov cuab yeej tshwj xeeb suav nrog cov khoom siv hluav taws xob tshawb pom electrostatic (EDD) thiab cov khoom siv los ua chemistry
Cov txheej txheem dab tsi uas tus kws tshawb fawb siv los tsim ntau cov ntawv luam ntawm DNA xav tau sau rau hauv daim ntawv dawb paug 1?
Molecular Cloning. Cloning tso cai rau tsim ntau cov ntawv luam ntawm cov noob, qhia cov noob, thiab kawm txog cov noob tshwj xeeb. Yuav kom tau txais cov DNA tawg rau hauv cov kab mob hauv cov kab mob hauv daim ntawv uas yuav tau theej lossis nthuav tawm, cov khoom tawg yog thawj zaug tso rau hauv plasmid
