Kev ntsuas kub thiab qis qis, tseem hu ua ib puag ncig kuaj chamber, yog tsim rau cov khoom lag luam, kev kub siab, ntsuas kub tsis tshua muaj kev ntseeg siab.Rau hluav taws xob thiab hluav taws xob engineering, tsheb thiab maus taus, aerospace, nkoj thiab riam phom, cov tsev kawm ntawv qib siab thiab cov tsev kawm qib siab, cov chaw tshawb fawb tshawb fawb thiab lwm yam khoom siv, cov khoom siv thiab cov khoom siv hauv qhov kub thiab txias, tsis tshua muaj kub (alternating) cyclic hloov nyob rau hauv qhov xwm txheej, kev xeem ntawm nws cov ntsuas kev ua tau zoo rau cov khoom tsim, kev txhim kho, kev txheeb xyuas thiab tshuaj xyuas, xws li: aging test.
