Teb 1: Ib qho hluav taws xob tig yog hais txog ib daim ntawv ntawm lub zog ntawm cov hluav taws xob Tsis tas li ntawd, nws yog quantum khoom ntawm electrons thiab nws qhov loj me tshwm sim mus tas li. Lub spin quantum tooj muab cov ntaub ntawv hais txog ib tug electron lub cim quantum xeev. Tsis tas li ntawd, cov spinning ua lub luag haujlwm tseem ceeb hauv quantum mechanics.
Yuav ua li cas thaum lub tshuab hluav taws xob tig?
Electron spin yog quantum khoom ntawm electrons. Nws yog ib daim ntawv ntawm angular momentum. Qhov loj ntawm lub angular momentum no mus tas li. … Yog hais tias lub electron tig clockwise ntawm nws axis, nws yog piav raws li spin-up; counterclockwise yog tig-down.
Yuav ua li cas tig ntawm ib qho hluav taws xob?
…kev txav txav ntawm lub tshuab hluav taws xob nrog lub quantum mechanical "spin" ntawm lub electron. Ib qho hluav taws xob tuaj yeem xav tias yog ib qho hluav taws xob uas siv hluav taws xob tig sab saum toj, thiab yog li nws coj zoo li lub hlau nplaum me me. Lub spinning electron cuam tshuam nrog lub magnetic teb uas tsim los ntawm lub electron rotation txog lub…
Vim li cas electrons tig?
Nyob rau hauv quantum theories, peb hais txog electrons muaj ib yam khoom hu ua "spin." Yog vim li cas peb siv lo lus no yog tias electrons muaj lub zog angular thiab lub sijhawm sib nqus, ib yam li ib tus xav tau rau lub cev hloov pauv.
Puas yog ib qho hluav taws xob muaj kiv?
Los txhais, electrons muaj qhov sib npaug ntawm 1/2. Lwm qhov hais tuaj yeem muaj qhov sib npaug ntawm 1, 3/2, 2 lossis txawm 0. Thiab qhov loj ntawm ib qho kev sib tw yuav txiav txim siab seb cov kev taw qhia ntawm kev sib tw peb tuaj yeem ntsuas tau.
