nyob ib ncig ntawm 150 nano Kelvin
Xav txog qhov no, peb tuaj yeem mus zero li cas?
Ntawm lub cev tsis tuaj yeem ncav cuag qhov kub ntawm xoom kelvin, los yog rho tawm 459.67 degrees Fahrenheit (rho tawm 273.15 degrees Celsius), atoms yuav tsum tsis txhob txav. Yog li ntawd, tsis muaj dab tsi ua tau yuav txias dua tsis muaj tseeb ntawm Kelvin scale.
Tsis tas li ntawd, yuav ua li cas tshwm sim ntawm qhov zero? Tsis muaj tseeb yog qhov ntsuas kub qis tshaj plaws uas tsis muaj dab tsi yuav txias dua thiab tsis muaj lub zog cua sov nyob hauv cov khoom. Tsis muaj tseeb yog lub ntsiab lus ntawm qhov tseem ceeb ntawm cov xwm txheej muaj qhov kev vibrational tsawg, khaws cia tsuas yog quantum mechanical, xoom -point zog-induced particle motion.
Tsuas yog li ntawd, qhov twg yog qhov tsis muaj tseeb?
Tsis muaj tseeb Tsis tuaj yeem ua tiav, txawm hais tias nws tuaj yeem ncav cuag qhov kub thiab txias los ntawm kev siv cov khoom siv cryocoolers, dilution tub yees, thiab nuclear adiabatic demagnetization. Kev siv laser txias tau ua kom kub tsawg tshaj li ib billionth ntawm ib kelvin.
Puas electrons txav ntawm zero kiag?
Nyob ze tsis muaj tseeb , electrons "mus txuas ntxiv mus ncig" hauv atoms, hais tias quantum physicist Christopher Foot ntawm University of Oxford. Ntxiv mus, txawm nyob rau tsis muaj tseeb , atoms yuav tsis nyob ruaj ruaj. Lawv yuav "jiggle txog," tab sis yuav tsis muaj zog txaus los hloov lub xeev. Nws lub zog yog yam tsawg kawg nkaus.
Pom zoo:
Koj yuav ua li cas paub yog tias qhov hloov pauv theem yog qhov zoo lossis tsis zoo?
Yog tias lub sijhawm hloov pauv yog xoom, qhov nkhaus pib ntawm keeb kwm, tab sis nws tuaj yeem txav mus rau sab laug lossis sab xis nyob ntawm theem hloov. Kev hloov pauv theem tsis zoo qhia txog kev txav mus rau sab xis, thiab theem zoo hloov pauv qhia tias txav mus rau sab laug
Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Qhov zoo li cas yog ib qho piv txwv ntawm qhov zoo ntawm tib neeg?
Qee qhov piv txwv ntawm qhov zoo muaj xws li daim tawv nqaij puag ncig / wrinkled nyob rau hauv peas pods, albinism thiab tib neeg cov ntshav ABO pawg. Cov pab pawg ABO tib neeg cov ntshav qhia txog lub tswv yim no zoo. Tsuas yog qee qhov tshwj xeeb tsis tshua muaj, tib neeg tuaj yeem haum rau hauv ib qho ntawm plaub pawg rau ABO ib feem ntawm lawv cov ntshav: A, B, AB lossis O
Vim li cas tsis zoo thiab tsis zoo yog qhov zoo?
Thaum koj muab qhov tsis zoo los ntawm qhov tsis zoo koj tau txais qhov zoo, vim tias ob lub cim tsis zoo raug muab tso tseg
Koj yuav ua li cas thiaj paub tias kev sib raug zoo yog qhov zoo lossis tsis zoo?
Qhov zoo correlation coefficient txhais tau hais tias raws li tus nqi ntawm ib qho kev sib txawv nce, tus nqi ntawm lwm qhov sib txawv nce; raws li ib tug txo qhov qis dua. Qhov tsis zoo correlation coefficient qhia tau hais tias raws li ib qho kev sib txawv nce, qhov txo qis, thiab vice-versa
