Cov taw tes ntawm uas cov dej saturated thiab saturated chav kab sib ntsib yog lub npe hu ua qhov tseem ceeb . Raws li lub siab nce mus rau lub qhov tseem ceeb lub enthalpy ntawm evaporation txo, kom txog rau thaum nws ua xoom ntawm lub qhov tseem ceeb.
Yog li ntawd, yuav ua li cas tshwm sim ntawm qhov tseem ceeb?
Hauv thermodynamics, a qhov tseem ceeb (los yog tseem ceeb xeev) yog qhov kawg taw tes ntawm ib theem equilibrium nkhaus. Cov piv txwv tseem ceeb tshaj plaws yog cov kua-vapor qhov tseem ceeb , qhov kawg taw tes ntawm lub siab-kub nkhaus uas xaiv cov xwm txheej raws li cov kua thiab nws cov vapor tuaj yeem ua ke.
Ib yam li ntawd, qhov txawv ntawm qhov tseem ceeb thiab triple point yog dab tsi? A qhov tseem ceeb (los yog tseem ceeb xeev) yog qhov kawg taw tes ntawm ib theem equilibrium. Triple point ntawm ib yam khoom yog qhov kub thiab siab uas peb theem (gas, kua, thiab khoom) ntawm cov khoom ntawd coexist nyob rau hauv thermodynamic equilibrium.
Kuj Paub, qhov kub tseem ceeb ntawm chav yog dab tsi?
Chav Generators Lub ntsiab lus ntawm qhov qhov kub thiab txias thiab tseem ceeb siab tau ntsib yog hu ua tseem ceeb taw tes. Cov tseem ceeb siab thiab qhov kub thiab txias ntawm dej thiab chav 22.12 MPa thiab 647.14 K, feem.
Vim li cas lub ntsiab lus tseem ceeb?
Qhov tseeb no feem ntau pab txheeb xyuas qhov sib txuas lossis hauv kev daws teeb meem. Cov qhov tseem ceeb yog qhov kub thiab siab tshaj plaws uas cov khoom siv ntshiab tuaj yeem muaj nyob hauv vapor/kua sib npaug. Thaum kub siab tshaj qhov tseem ceeb qhov kub thiab txias, cov khoom tsis tuaj yeem nyob ua kua, txawm tias lub siab npaum li cas.

Vim li cas qhov tseem ceeb ntawm qhov tseem ceeb?
Thaum koj pom tus nqi kiag li hauv qhov teeb meem lossis qhov sib npaug, nws txhais tau hais tias txhua yam nyob hauv tus nqi tiag tiag yog qhov zoo. Cov txiaj ntsig tsis zoo feem ntau siv rau hauv cov teeb meem cuam tshuam nrog kev nyob deb thiab qee zaum siv nrog qhov tsis sib xws. Qhov ntawd yog qhov tseem ceeb uas yuav tsum nco ntsoov nws zoo li qhov deb ntawm xoom
Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws cov DNA mus rau ob lub hlwb zoo tib yam
Vim li cas cov nuj nqis tseem ceeb tseem ceeb thaum qhia txog kev ntsuas?
Cov duab tseem ceeb yog qhov tseem ceeb los qhia qhov tseeb ntawm koj cov lus teb. Qhov no yog qhov tseem ceeb hauv kev tshawb fawb thiab engineering vim tias tsis muaj cov cuab yeej ntsuas tuaj yeem ua qhov ntsuas nrog 100% precision. Siv cov nuj nqis tseem ceeb tso cai rau tus kws tshawb fawb paub tias cov lus teb meej npaum li cas, lossis qhov tsis paub meej npaum li cas
Dab tsi yog 2 qhov tseem ceeb ntawm lub voj voog ntawm tes thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Cov xwm txheej no tuaj yeem muab faib ua ob qhov tseem ceeb: interphase (hauv nruab nrab ntawm kev sib faib theem ua pawg G1 theem, S theem, G2 theem), thaum lub xov tooj ntawm tes tsim thiab ua nrog nws cov haujlwm metabolic; mitotic theem (M mitosis), thaum lub sij hawm lub cell yog replicating nws tus kheej
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
