Quasi - Txheej txheem Equilibrium

A txheej txheem thaum lub sij hawm uas lub system tsuas deviates los ntawm kev sib npaug los ntawm tus nqi infinitessimal. Raws li lub piston compresses cov roj hauv lub tog raj kheej, lub siab hauv cov roj tseem nyob ze li qub txhua lub sijhawm thaum lub sijhawm txheej txheem.

Ib yam li ntawd, tib neeg nug, dab tsi yog txheej txheem quasi equilibrium dab tsi yog qhov tseem ceeb hauv engineering?

Dab tsi yog nws qhov tseem ceeb hauv engineering ? Quasi – kev sib npaug :- Kev tawm mus ntawm lub xeev ntawm qhov system los ntawm thermodynamic kev sib npaug lub xeev yuav yog infinitesimally me me. Yog li txhua lub xeev dhau los ntawm qhov system yuav yog ib qho kev sib npaug xeev.

Ib yam li ntawd, vim li cas quasi static txheej txheem tseem ceeb? Hauv cov thermodynamics, peb yuav tsum txheeb xyuas qhov sib txawv txheej txheem , uas yog xav tias tau tshwm sim quasi - statically los yog hauv quasi - kev sib npaug . Qhov no yog tseem ceeb vim peb yuav pom me ntsis tom qab ntawd quasi - cov txheej txheem zoo li qub tuaj yeem raug cais raws li thim rov qab txheej txheem thiab lwm yam.

Tom qab, lo lus nug yog, dab tsi yog lub xeev txheej txheem?

Hauv thermodynamics, a quasi - txheej txheem zoo li qub yog thermodynamic txheej txheem uas tshwm sim maj mam txaus rau qhov system kom nyob twj ywm hauv qhov sib npaug. Txhua yam thim rov qab txheej txheem yog a quasi - zoo li qub ib. Txawm li cas los xij, quasi - cov txheej txheem zoo li qub koom nrog entropy ntau lawm yog tsis thim rov qab.

Polytropic txhais li cas?

Lub sij hawm " polytropic " yog Ameslikas coined los piav qhia txog cov txheej txheem thim rov qab ntawm txhua qhov qhib lossis kaw ntawm cov pa roj lossis vapor uas cuam tshuam nrog cov cua sov thiab ua haujlwm hloov pauv, xws li kev sib xyaw ua ke ntawm cov khoom tau khaws cia tas mus li thoob plaws hauv cov txheej txheem.
