Theoretical vacuum thiab lub tshuab nqus tsev yog qhov zoo sib xws, uas feem ntau yog siv hauv cov khoom nqus khoom, xws li cov tshuab nqus tsev me me, lub tshuab cua kub yam me, cov pa roj gas, cov pa roj hmab twj, thiab lwm yam. raws li 0, qhov kev sib txuas lus theoretical, qhov nqus qhov kawg, txhais tau hais tias tsis muaj teeb meem (xws li cov khoom siv roj ntsha, lwm yam khoom siv) hauv lub xeev, uas tsuas yog theoretical state xwb thiab tsis tuaj yeem ua tiav hauv kev xyaum.
Qhov txo tus nqi siab yog, uas yog, qhov siab zog ntawm cov khoom nqus tsev yog, qhov ze nws yog theoretical nqus tsev thiab qhov kawg ntawm lub tshuab nqus tsev, thiab qhov zoo dua lub tshuab nqus tsev ntawm lub twj tso kua mis. Txawm li cas los xij, cov cai yuav tsum muaj nyob rau hauv cov khoom hauv lub neej, sealing tej yam kev mob, qhov chaw ua haujlwm ntawm qhov chaw thiab yog li kuj tau zoo heev.
Nrog rau kev ntsuas kev ntsuas thiab ntsuas kev lag luam thiab cov neeg yuav tsum muaj kev tiv thaiv ib puag ncig, muaj cov xav tau qis dua rau lub tshuab nqus tsev me me uas tsis tshua muaj nqi, tsis muaj roj los yog cov pa phem, tsis muaj zog thiab cov khoom loj.
