PROSESSI BARGARDANDA

PROSESSI BARGARDANDA dar termodinamika, prosessi az yak holat ba holati digar guzashtani sistemai termodinamikiro guyand, ki zimni on sistema silsilai holathoi mobayniro bo tartibi aks az cap guzaronda, ba holati avvala bargashta metavonad. Baroi in prosess boyad ba darajae sust guzarad, ki onro hamchun qatori muttasili holathoi muvozin muoina kardan mumkin gardad, yane in prosess nisbat ba prosesshoi barqarorshavii muvozinati termodinamiki dar sis­temai mazkur boyad susttar jori shavad. Aslan baroi Prosessi bargardanda nihoyat sust tagyir yoftani parametrhoi termodinamikie khos ast, ki muvozinati sistemaro muayyan mekunand (zichi, fishor, harorat va gayra). In prosesshoro kvazistatisti yo kvazimuvozinati ham meno­mand.

Prosessi bargardanda yake az mafhumi asosii termodinamikai makroskopii muvozini meboshad. Mahz zimni termodinamikai makroskopii muvozini qonunhoi yakum va duyumi termo­dinamika baroi Prosessi bargardanda ifoda meyoband.

Prosesshoi tabii bo yagon surati muayyan va hamroha bo parokanishi energiya (ba sababi so­ish, garmiguzaroni va gayra) jori meshavand, binobar on onho prosesshoi barnagardandaand. Prosessi bargardanda yak nav tasviri idealii chunin prosesshoi susti tabiat meboshad, ki hangomi tavsifashon hodisahoi barnagardandaro ba etibor nagiriftan mumkin ast. Nazariyai mik­roskopii Prosessi bargardandaro dar fizikai sta­tisti meomuzand.
