Quasi - zoo li qub load txhais tau hais tias lub load yog siv maj mam hais tias tus qauv deforms kuj qeeb heev (tsawg heev npaum li cas) thiab yog li ntawd lub inertia. zog me me heev thiab tuaj yeem tsis quav ntsej

Hauv qhov no, lub ntsiab lus ntawm quasi static yog dab tsi?

Hauv thermodynamics, a quasi - zoo li qub txheej txheem yog txheej txheem thermodynamic uas tshwm sim maj mam txaus rau lub kaw lus kom nyob twj ywm hauv qhov sib npaug. Cov txheej txheem thim rov qab yog ib qho quasi - zoo li qub ib. Txawm li cas los xij, quasi - zoo li qub cov txheej txheem uas muaj entropy ntau lawm yuav tsis thim rov qab.

Dab tsi yog cov yam ntxwv ntawm quasi static txheej txheem? Quasi txhais tau tias yuav luag thiab zoo li qub txhais tau hais tias cov khoom thermodynamic zoo li qub nrog lub sijhawm. Quasi static txheej txheem kuj yog ib tug reversible txheej txheem . Infinite slowness yog yam ntxwv feature ntawm quasi static txheej txheem . Yog hais tias lub gradient yog tam sim no nyob rau hauv lub system zog ces tus txheej txheem ua tsis tau qis static rau lub sijhawm kawg.

Tsis tas li lo lus nug yog, 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.

Dab tsi yog qhov sib txawv loj ntawm cov txheej txheem quasi zoo li qub thiab thim rov qab?

A quasi static txheej txheem yog a txheej txheem nqa tau qeeb heev, hauv ib sim mus kom ze li sai tau rau a txheej txheem thim rov qab . sawv cev rau qhov entropy pauv mus rau hauv lossis tawm ntawm qhov system. Qhov no tuaj yeem yog 0, zoo lossis tsis zoo raws li rooj plaub.
