Ukunyangwa kokuphazamiseka kwegumbi lokuvavanya ukushisa okuphezulu kunye neqondo eliphantsi lichazwe ngokucacileyo kwi-GJB 150, eyahlula ukuphazanyiswa kovavanyo kwiimeko ezintathu, oko kukuthi, ukuphazamiseka ngaphakathi koluhlu lokunyamezela, ukuphazamiseka phantsi kweemeko zovavanyo kunye nokuphazamiseka phantsi kweemeko zokuvavanya. Iimeko ezahlukeneyo zineendlela ezahlukeneyo zonyango.
Ukuphazamiseka ngaphakathi kwinqanaba lokunyamezela, xa iimeko zovavanyo zingagqithisi uluhlu lwempazamo oluvumelekileyo ngexesha lokuphazamiseka, ixesha lokuphazamiseka kufuneka lithathwe njengenxalenye yexesha lokuvavanya lilonke; ukuphazamisa phantsi kweemeko zovavanyo, xa iimeko zovavanyo lwegumbi lokuvavanya ubushushu obuphezulu kunye obuphantsi buphantsi kunomda ophantsi wempazamo evumelekileyo, iimeko zovavanyo ezichazwe kwangaphambili kufuneka zifikelelwe kwakhona ukusuka kwindawo engezantsi kweemeko zovavanyo, kunye novavanyo. kufuneka iqaliswe kwakhona de umjikelo wovavanyo ocwangcisiweyo ugqitywe; kwiisampuli zokuvavanya ngokugqithiseleyo, ukuba iimeko zokuvavanya ngokugqithiseleyo aziyi kuchaphazela ngokuthe ngqo ukuphazamiseka kweemeko zovavanyo, ukuba isampuli yovavanyo iyasilela kuvavanyo olulandelayo, umphumo wokuvavanya kufuneka uthathwe njengento engekho.
Kumsebenzi wangempela, samkela indlela yokuvavanya kwakhona emva kokuba isampuli yovavanyo ilungiswe ngenxa yokuphazamiseka kovavanyo olubangelwa ukungaphumeleli kwesampuli yovavanyo; kuphazamiseko lovavanyo olubangelwa phezulu naphantsiuvavanyo lwegumbi lovavanyo lobushushut izixhobo (ezifana nokuphuma kwamanzi ngequbuliso, ukuphuma kombane, ukungaphumeleli kwezixhobo, njl.), ukuba ixesha lokuphazamiseka alide kakhulu (ngaphakathi kweeyure ze-2), ngokuqhelekileyo siphatha ngokuhambelana nokuphazamiseka kwemeko engaphantsi kovavanyo oluchazwe kwi-GJB 150. Ukuba ixesha lide kakhulu, uvavanyo kufuneka luphindwe. Isizathu sokusebenzisa izibonelelo zonyango lokuphazamiseka kovavanyo ngale ndlela kuchongwa ngamalungiselelo okuzinza kweqondo lokushisa kwisampuli yovavanyo.
Ukumiselwa kwexesha lobushushu bovavanyo kwindawo ephezulu naphantsiigumbi lovavanyo lobushushuuvavanyo lobushushu luhlala lusekelwe kwisampuli yovavanyo ukufikelela uzinzo lobushushu kobu bushushu. Ngenxa yomahluko kwisakhiwo semveliso kunye nezixhobo kunye nobuchule bezixhobo zokuvavanya, ixesha leemveliso ezahlukeneyo ukufikelela kuzinzo lobushushu kubushushu obufanayo liyahluka. Xa umphezulu wesampuli yovavanyo ishushu (okanye ipholile), ngokuthe ngcembe idluliselwe ngaphakathi kwisampuli yovavanyo. Inkqubo yokuqhuba ubushushu yinkqubo ezinzileyo yokuqhuba ubushushu. Kukho i-lag yexesha phakathi kwexesha apho ubushushu bangaphakathi besampula yovavanyo bufikelela kwi-equilibrium ye-thermal kunye nexesha apho umphezulu wesampuli yovavanyo ufikelela kwi-equilibrium ye-thermal. Eli xesha lelag lixesha lokuzinzisa ubushushu. Ubuncinci bexesha elifunekayo kwiisampuli zokuvavanya ezingakwazi ukulinganisa ukuzinza kweqondo lokushisa lichaziwe, oko kukuthi, xa iqondo lokushisa lingasebenzi kwaye alinakulinganiswa, ixesha elincinci lokuzinza kweqondo lokushisa liyi-3 iiyure, kwaye xa ubushushu busebenza, ubushushu obuncinane. ixesha uzinzo 2 iiyure. Kumsebenzi wangempela, sisebenzisa iiyure ezi-2 njengexesha lokuzinzisa ubushushu. Xa isampuli yovavanyo ifikelela kuzinzo lobushushu, ukuba iqondo lobushushu elijikeleze isampulu yovavanyo litshintsha ngesiquphe, isampuli yovavanyo kwi-equilibrium thermal nayo iya kuba ne-lag yexesha, oko kukuthi, ngexesha elifutshane kakhulu, ubushushu ngaphakathi kwisampulu yovavanyo aluyi kutshintsha kakhulu. kakhulu.
Ngexesha lovavanyo lobushushu obuphezulu noluphantsi, ukuba kukho ukuphuma kwamanzi ngequbuliso, ukuphuma kombane okanye ukusilela kwezixhobo zokuvavanya, kufuneka siqale sivale umnyango wegumbi lovavanyo. Ngenxa yokuba xa izixhobo zokuvavanya ubushushu obuphezulu kunye nobushushu obuphantsi buyeka ukusebenza ngokukhawuleza, ukuba nje umnyango wegumbi uvaliwe, ubushushu bomnyango wegumbi lovavanyo abuyi kutshintsha kakhulu. Ngexesha elifutshane kakhulu, iqondo lokushisa ngaphakathi kwisampuli yovavanyo ayiyi kutshintsha kakhulu.
Emva koko, qaphela ukuba oku kuphazamiseka kunempembelelo kwisampuli yovavanyo. Ukuba ayichaphazeli isampuli yovavanyo kunye neizixhobo zovavanyosinokuphinda siqalise ukusebenza okuqhelekileyo ngexesha elifutshane, sinokuqhubeka novavanyo ngokwendlela yokusingatha ukuphazamiseka kweemeko zovavanyo ezinganeleyo ezichazwe kwi-GJB 150, ngaphandle kokuba ukuphazamiseka kovavanyo kunempembelelo ethile kwisampuli yovavanyo.
