Imolekyuli yeoksijini inyibilikiswe emanzini ibizwa ngokuba yioksijini enyibilikileyo kwaye idla ngokubhalwa D0.Ubungakanani beoksijini enyibilikisiweyo kumanzi angaphezulu ngu-5-10mg/L.Xa kukho imimoya enamandla kunye namaza, ioksijini enyibilikayo emanzini inokufikelela kwi-14mg / L.Ukuchithwa kwe-oksijeni echithwe = ixabiso elilinganisiweyo le-oksijeni echithwe / i-oksijeni echithwe phantsi kweemeko ezilinganisiweyo * 100%, oko kukuthi, i-90% nangaphezulu, ixabiso elilinganisiweyo lingaphezulu kwe-7.5 mg / L, kwaye ubuncinci yi-2 mg / L.
I-oksijini ephantsiamanziiya kudlula kwizityalo kwaye isuse ioksijini kwinkqubo yeengcambu.Ngokufanayo, iya kuphelisa ioksijini emhlabeni.Izityalo ezisempilweni kunye nezityalo zomhlaba ezisempilweni zidinga ioksijini kula macandelo mabini.
Ukungabikho kweoksijini enyibilikisiweyo emanzini kunokubangela ezinye iingxaki.Ngokomzekelo, i-nematodes ifana nomhlaba we-hypoxic.Ukunkcenkceshela izityalo ngamanzi e-oksijini ephantsi kuya kubasondeza kumphezulu kwaye bonakalise ngokulula iingcambu zezityalo.
Uphononongo lubonise ukuba ukunciphisa ukuxinana kweoksijini enyibilikisiweyo kwindawo yengcambu yezityalo kuya kunciphisa amandla ezityalo okufunxa initrogen namanzi.Ukungabikho kweoksijini kungonakalisa iingcambu.Kwinkqubo yokulungelelanisa kwiindawo eziphantsi ze-oksijini edibeneyo, i-metabolism yezityalo ishintshile.I-Hypoxia ngaphakathi kwesityalo ibizwa ngokuba yi-internal hypoxia.Esinye seziphumo kukuthotywa kwe-sucrose, kwaye izityalo ziphendukela kwiindlela zokonga amandla ukubuyisela ukungabikho kwe-oksijini.
I-photosynthesis ye-phytoplankton ngowona mthombo we-oksijini kumachibi, ngokuqhelekileyo ibala i-56% -80% yomthombo we-oksijini;ukuphumla kuvela ekuvuthuzeni komoya kunye namaza, ukuze ioksijini esemoyeni inyibilike ngokuthe ngqo kwiamanzi.I-Advantageous 12-14mg/L
IHeilongjiang: A 600-square-imithaIdama lokutshisa umzimba linokunyusa ubushushu bamanzi nge-3 ukuya kwi-4 degrees kunye nokwandisa imveliso yeenkozo nge-6%.
