Yooj Yim! Raws li kev xav Puas Yuav Muaj Hauv Lwm Cov Sab Hauv Atom

  • Cov hluav taws xob muaj tsawg heev hauv kev sib piv rau lwm qhov ntawm cov atom.
  • Yog tias huab tais daim duab hloov tawm mus ua me ntsis nkhaus, qhov no yuav yog qhov pom ntawm cov khoom tawg tshiab uas mus dhau tus qauv ntawm cov qauv qib elementary physics.
  • Nws yog qhov ntxim nyiam ua haujlwm thiab lwm txoj kev kawm txaus siab hauv theoretical physics.

Kev ua haujlwm tshiab tau tshaj tawm hais txog kev tawm dag zog raws kev koom tes nrog Lavxias thiab German physicists, hais txog tus cwj pwm ntawm cov khoom siv hluav taws xob hauv cov atoms nrog isotopes sib txawv ntawm tib lub keeb. Cov hluav taws xob tsis zoo them cov khoom ntawm cov atom. Ua ke, tag nrho cov hluav taws xob ntawm ib qho atom tsim qhov tsis zoo uas ua kom muaj qhov them tau qhov zoo ntawm cov protons hauv atomic nucleus. Cov hluav taws xob muaj tsawg heev hauv kev sib piv rau lwm qhov ntawm cov atom.

Isotopes muaj qhov sib txawv ntawm qee yam tshuaj lom neeg uas txawv ntawm neutron, thiab yog li ntawm nucleon tus naj npawb. Txhua isotopes ntawm ib qho kev muab muaj tib tus lej ntawm protons tab sis tus lej sib txawv ntawm neutrons hauv txhua atom. Li no, thaum ib qho cuab yeej hluav taws xob hauv ib qho atom txav los ntawm theem siab ntawm lub zog mus rau qis dua ib qho, nws tawm cov duab photon ntawm qhov ntsuas tau nruj. Cov kws kho mob hauv lub cev tau hais tias ntawm lub zaus no muaj kab hluav taws xob rau txoj kev hloov no.

Muaj ntau ntau qib zog hauv lub atom, yog li muaj ntau txoj kev hloov mus thiab cov kab hluav taws xob. A photon yog ib qhov me me ntawm lub teeb uas yeej tseem ceeb yog pob ntawv ntawm hluav taws xob hluav taws xob. Lub zog ntawm cov photon nyob ntawm nws cov zaus (sai npaum li cas cov hluav taws xob teb thiab sib nqus daim teb qoj ib ce). Qhov ntau dua qhov ntau zaus, ntau lub zog photon muaj. Isotopes yog ntau yam ntawm ib qho kev tshuaj lom neeg uas sib txawv hauv tus naj npawb ntawm neutrons hauv lub keeb.

Tsis tas li ntawd, tib txoj kab hluav taws xob ib leeg muaj kev ua kom sib txawv rau cov isotopes sib txawv. Cov nyhuv no hu ua isotopic hloov. Lub isotopic ua haujlwm yog kev hloov chaw hauv ntau hom kev tsom iav uas tshwm sim thaum ib qho nuclear isotope hloov los ntawm lwm qhov. Qhov sib txawv ntawm kab ntau zaus ntawm ob isotopes tuaj yeem yog qhov feem me me ntawm ib feem pua ​​ntawm qhov zaus nws tus kheej, tab sis rau cov thev naus laus zis niaj hnub no yog qhov muaj peev xwm ntsuas tau. Txhua khub ntawm isotopes ntawm no thiab txhua ntawm nws cov kab spectral nws muaj isotopic hloov. Tom qab koj xaiv ib qho khoom thiab ib txoj kab xim, koj tuaj yeem tsim lub rooj uas ib kem muaj ib khub isotopes, thiab lwm kem muaj cov isotopic hloov ntawm cov kab no rau nws.

Raws li Vladimir Yeroshkin ntawm Petersburg Polytechnic University, yog tias huab tais daim duab hloov mus ua ib qho me ntsis nkhaus, qhov no yuav yog qhov kev cuam tshuam ntawm cov lus tshiab uas mus dhau tus qauv txheej txheem ntawm cov khoom tawg thaum yau. [Peter the Great St. Petersburg Polytechnic University, hais luv li SPbPU, yog ib lub tsev kawm ntawv qib siab hauv Lavxias txuj ci nyob hauv Saint Petersburg. Lwm lub npe qub muaj xws li Peter the Great Polytechnic Institute thiab Kalinin Polytechnic Institute.]

Cov kws kho mob muab xam ua huab tais daim duab kos rau cov duab kab mob argon ionsCov. Argon ions raug tsim tom qab, thiab lawv cov nyiaj tau nce ntxiv los ntawm kev sib tsoo ntawm cov hluav taws xob dawb nrog qhov nruab nrab Ar atoms mus txog qhov xwm txheej tsis sib thooj qhov chaw uas muaj ntshav khov. Cov kws tshawb fawb ntsia ions nrog plaub, tsib, thiab rau hluav taws xob. Cov "atoms" no yooj yim heev rau kev kawm theoretical thiab hauv kev sim. Cov kws tshawb nrhiav pom tias kev hloov pauv los ntawm cov kab ncaj nraim muaj li ntawm 5 txog 3 kilohertz. Lub hertz yog cov nqis los ntawm zaus hauv International System ntawm Chav Nyob thiab tau txhais tias yog mus ncig rau ib thib ob. Nws tau npe tom qab Heinrich Rudolf Hertz, thawj tus neeg los muab cov ntaub ntawv pov thawj ua tiav ntawm cov hluav taws xob muaj hluav taws xob. Nws txhais tau tias nws yog txhiab lub sijhawm ntau dua li yav dhau los theoretical suav nyob rau hauv cov sib piv.

Nws yog qhov ntxim nyiam ua haujlwm thiab lwm txoj kev kawm txaus siab hauv theoretical physics.
