A khov kho - xeev yog ib qho kev hloov pauv, uas tseem zoo ib yam tom qab kev txhawb nqa / hloov pauv. Thaum a qhov system sim ua kom tiav a nyob khov kho , Cov lus teb xav tau ntawm cov cim tshwj xeeb tau ua tiav uas tuaj yeem ua raws li kev xav tau raws li lub sijhawm mus rau infinity. Piv txwv li, thaum ib tug nias lub hwj chim khawm incell-phone, xov tooj ntawm tes khau boots.
Tsis tas li ntawd, lub xeev khov kho yog dab tsi?
Lub ntsiab txhais ntawm a khov kho - xeev yog anunchanging mob, qhov system los yog txheej txheem lub cev uas tseem zoo ib yam txawm tias tom qab hloov pauv lossis hloov pauv. Thaum koj muaj cov tshuaj sib xyaw uas muaj qee yam khoom, thiab cov khoom sib xyaw khaws cia txawm tias tom qab koj ntxiv tus neeg hloov pauv, qhov no yog qhov piv txwv ntawm ib qho khov kho - xeev.
Tsis tas li ntawd, lub xeev khov kho txhais li cas rau cov thermodynamics? Thermodynamics Phau ntawv | Thaum tshav kub kub TransferDirectory. Lub xeev khov kho yog qhov xwm txheej uas tsis muaj qhov sib txuam ntawm huab hwm coj lossis lub zog hauv lub ntim tswj, thiab cov khoom ntawm txhua qhov chaw hauv qhov system yog ywj pheej ntawm lub sijhawm. Lub xeev khov kho yog ib qho teeb meem dav dav dua li dynamicequilibrium.
Yog li ntawd, dab tsi yog lub xeev ruaj khov yuam kev hauv kev tswj hwm?
Tsis tu ncua - xeev yuam kev txhais tau tias yog qhov sib txawv ntawm cov tswv yim (command) thiab cov zis ntawm a qhov system nyob rau hauv txwv raws li lub sij hawm mus rau infinity (piv txwv li thaum theresponse tau mus txog nyob khov kho ). Cov khov kho - xeev yuam kev yuav nyob ntawm seb hom kev tawm tswv yim (kauj ruam, ramp, thiab lwm yam) thiab qhov system type (0, I, or II).
Dab tsi yog qhov txawv ntawm kev hloov pauv thiab nyob ruaj khov?
Cov nyob khov kho yog cov xeev uas tau tsim tom qab ib lub sijhawm hauv koj lub cev. Cov transientstate yog qhov pib nruab nrab qhov pib ntawm qhov eventand nyob khov kho . Yuav kom rov qab los rau lub neej tiag tiag: Thaum koj qhib da dej, dej ntws tawm sai sai thiab qhov kub thiab txias nyob rau hauv ib lub xeev hloov.

Dab tsi yog kev saib xyuas ntawm kev ruaj ntseg sab hauv txawm tias muaj kev hloov pauv hauv ib puag ncig sab nraud?
Kev saib xyuas ntawm kev ruaj ntseg sab hauv txawm tias muaj kev hloov pauv hauv ib puag ncig sab nraud yog hu ua homeostasis
Dab tsi yog qhov sib npaug ntawm kev tswj hwm rau lub capacitor?
Qhov sib npaug capacitor hais tias kuv = C dv/dt. Kev hloov pauv ntse txhais tau tias dv / dt yuav yog tus nqi loj heev rau lub sijhawm luv luv. Yog hais tias qhov kev hloov pauv voltage yog tam sim no qhov sib npaug kwv yees lub mem tes ntawm infinite tam sim no nyob rau hauv xoom lub sij hawm
Yam khoom twg tsis muaj qhov ruaj khov thiab tsis muaj qhov ntim ruaj khov?
Cov theem ntawm cov teeb meem uas tsis muaj qhov ntim ruaj khov thiab tsis muaj qhov ruaj khov yog cov roj. Cov roj tsis muaj qhov ruaj khov
Dab tsi yog kev tswj zoo thiab kev tswj tsis zoo hauv gel electrophoresis?
Kev tswj qhov zoo thiab qhov tsis zoo yog cov qauv uas tau siv los lees paub qhov siv tau ntawm gel electrophoresis sim. Cov kev tswj tau zoo yog cov qauv uas muaj cov cim paub txog DNA lossis cov protein thiab yuav txav mus rau ib txoj hauv kev tshwj xeeb ntawm cov gel. Kev tswj tsis zoo yog cov qauv uas tsis muaj DNA lossis cov protein
Cov cai tswj kev tswj hwm yog dab tsi?
Kev hloov pauv hauv lub dav hlau sib koom tes feem ntau yog sawv cev los ntawm 'coordinate rules' ntawm daim ntawv (x, y) --> (x', y'). Qhov no txhais tau hais tias ib lub ntsiab lus uas nws cov kev tswj hwm yog (x, y) tau kos npe rau lwm lub ntsiab lus uas nws cov kev tswj hwm yog (x', y')
