Tswvyim thiab daim ntawv thov huab nqus tsev

Txwv cov tswvyim nqus
Lub npe ntawm "huab nqus tsev" yog "lub tshuab nqus tsev", uas yog hais txog ntau lub tshuab nqus tsev uas tuaj yeem ua tiav los ntawm lub tshuab nqus tsev me me.
Ib lub tshuab nqus tsev vacuum yog ib lub xeev uas tsis muaj teeb meem (molecules, atoms, etc.) nyob rau tam sim no. Qhov no yog ib qho theoretical lub xeev uas tsis muaj peev xwm ua kom tiav.
Piv txwv, ib lub tshuab nqus cov tshuab nqus tau muaj peev xwm txo tau cov roj tawm hauv lub thawv ntim ntawm 100KPa rau 95KPa ib zaug tom qab lub sijhawm me me xwb. Tom qab ntawd 95KPa yog qhov kawg nqus tsev ntawm lub twj tso kua mis no. Piv txwv li, muaj lub tshuab nqus tsev me me nrog lub zog muaj zog, uas tuaj yeem txo cov cua ntawm 100KPa mus rau 10KPa, ces 10KPa yog qhov huab nqus ntawm cov twj no.
Daim ntawv thov huab cua nqus tsev
"Lub tshuab nqus tsev" yog ib qho tseem ceeb ntawm lub tshuab nqus tsev twj, uas yog tus yam ntxwv ntawm lub peev xwm ntawm lub twj tso kua mis thiab cov nqi ntawm lub tshuab nqus tsev twj. Lub tshuab nqus tsev twj sib txawv muaj peev xwm sib txawv ntawm "huab nqus tsev". Thiab "theoretical vacuum" yog ib lub tswvyim hauv kev tshawb nrhiav theoretical, thiab nws yog qhov zoo tshaj plaws lub xeev lub xeev tau muab rho tawm los ntawm kev tshem tawm tus yam ntxwv ntawm cov tswv yim ntau yam. Lub nkoj nqus tsev yog nyob ntawm ib lub tshuab nqus tsev tom qab tag nrho cov dej ntim, uas yog hu ua lub qhov nqus dej. Feem ntau, lub nkoj nqus tsev yuav tsum tau siv 12 teev cov roj refining, tom qab 12 teev ntawm lub tshuab nqus tsev, thiab lub sijhawm kawg yog ntsuas txhua 10 feeb. Tus nqi nruab nrab ntawm 10 npaug yog li qhov txwv nqus tus nqi.
