I-nitrogen ewuketshezi: Igesi ye-nitrogen esesimweni soketshezi. Ayinawo umbala, ayinaphunga, ayiboli, ayishisi, izinga lokushisa elibangela ukucasuka okukhulu. I-nitrogen yakha ingxenye enkulu yomkhathi (78.03% ngobuningi kanye no-75.5% ngesisindo). I-nitrogen ayisebenzi futhi ayisekeli ukusha. I-frostbite ebangelwa ukuthintana ngokweqile kwe-endothermic ngesikhathi sokuhwamuka.
I-nitrogen ewuketshezi iwumthombo obandayo olula. Ngenxa yezakhiwo zayo ezihlukile, i-nitrogen ewuketshezi iye yanakwa kancane kancane futhi yaqashelwa abantu. Isetshenziswe kabanzi kakhulu ekufuyweni kwezilwane, embonini yezokwelapha, embonini yokudla, kanye nasemasimini ocwaningo lwe-cryogenic. Kwezobuchwepheshe, i-metallurgy, i-aerospace, ukukhiqizwa kwemishini kanye nezinye izici zohlelo lokusebenza ibilokhu ikhula futhi ithuthuka.
Amakhono okuqoqa amagciwane e-nitrogen ewuketshezi
Isimiso sendlela yokuqoqa i-nitrogen ewuketshezi, eqoqa izinhlobo zamabhaktheriya ku--196℃, ukuqoqa ama-microorganism ngempumelelo ngokusebenzisa ukuthambekela kokumisa ukusebenza kwe-metabolism yama-microorganisms ngaphansi kuka--130℃. Ama-Macrofungi ayiqembu elibalulekile lama-fungi (ama-fungi akha imizimba emikhulu yezithelo kuma-fungi, ngokuvamile abhekisela kuma-mushroom noma ama-mushroom ngomqondo obanzi). Izinhlobo eziningi zinezindleko zokudla eziphezulu kanye nezindleko zokwelapha, futhi zinethuba elihle lokusebenzisa phakathi kwama-fungi. Ngaphezu kwalokho, amanye ama-fungi amakhulu angahlaziya izitshalo ezifile, ezidlala indima ebalulekile ekugcineni ukujikeleza kwezinto zemvelo kanye nokulinganisela kwemvelo, futhi zingathuthukiswa futhi zisetshenziswe embonini yamaphepha kanye nokuhlanzwa kwemvelo. Amanye ama-fungi amakhulu angabangela izifo zezihlahla noma alimaze imikhiqizo ehlukahlukene yokhuni. Ukuthuthukiswa kokuqonda la ma-fungi abangela izifo kusiza ekuvimbeleni nasekuqedeni umonakalo. Iqoqo eliyisibonelo lama-macrofungi libaluleke kakhulu ekuthuleni nasekuqoqweni kwezinsiza zezinhlobo zamagciwane, ukuqoqwa okuhlala njalo nokuwusizo kwezinsiza zofuzo, kanye nokwabelana ngezinhlobonhlobo zezinto eziphilayo ezindaweni ezahlukene.
Ukusinda kwezakhi zofuzo zezinto eziphilayo zezolimo
IShanghai itshale imali engaphezu kwezigidi ezingama-41 zama-yuan ukuze isungule futhi isebenzise isizindalwazi esiphelele sezakhi zofuzo zezolimo eShayina. Imboni yembewu, enekhono lokuvula imakethe yomhlaba wonke, izosebenzisa ibhange lezakhi zofuzo njengomthombo wezinto zokuzalanisa, kusho imboni yezolimo. I-Shanghai Agricultural Biological Gene Bank, enendawo engamamitha-skwele angu-3,300, izotholakala eShanghai Academy of Agricultural Sciences. Izoqoqa izinhlobo ezinhlanu zezinsiza zofuzo zezolimo ezihlanganisa imbewu yezitshalo, izinto ezingaphandle kwezitshalo, amaseli okuzala ezilwaneni, izinhlobo ezincane kanye nezinto zobunjiniyela bezakhi zofuzo zezitshalo.
Umuthi womkhuhlane
Ukuthuthukiswa okusheshayo kwemithi ye-cryogenic yezokwelapha kukhuthaze ukuthuthukiswa kwemithi yokufakelwa, ikakhulukazi ku-bone morrow, kumaseli e-hematopoietic stem, esikhumbeni, e-cornea, kuma-gland angaphandle, emithanjeni yegazi kanye nama-valve, njll. Ukufakelwa kwe-hematopoietic stem cell okuphumelelayo kuncike ekusindeni kwamaseli e-hematopoietic stem. Enqubweni yokupholisa nokuqandisa amasampula ebhayoloji, ngesikhathi sokuguquka kwesigaba kusuka koketshezi kuya kokuqinile, ukushisa okuthile kuzokhishwa futhi izinga lokushisa lakho lizokhuphuka. Inqubo yokuqandisa ngaphandle kokulawula izinga lokupholisa izoholela ekufeni kwamaseli esakhiwo. Isihluthulelo sokuthuthukisa izinga lokusinda kwamasampula aqandisiwe ukunquma kahle iphuzu lokushintsha kwesigaba samasampula ebhayoloji nokusebenzisa i-microcomputer ukupholisa ijubane ukuze kwandiswe inani lokufakwa kwe-nitrogen ewuketshezi ngesikhathi sokushintsha kwesigaba, ukucindezela ukukhuphuka kwezinga lokushisa kwamasampula okushintsha kwesigaba nokwenza amaseli adlule ushintsho lwesigaba buthule futhi ngokushesha.
Imithi yokwelapha
I-nitrogen ewuketshezi iyi-refrigerant esetshenziswa kabanzi ekuhlinzeni nge-cryosurgery. Iyi-refrigerant esungulwe kuze kube manje, futhi uma uyijova kudivayisi yezokwelapha ye-cryogenic, isebenza njenge-scalpel, futhi ungenza noma yikuphi ukuhlinzwa. I-Cryotherapy iwukwelashwa okusebenzisa izinga lokushisa le-cryogenic ukuphula isakhiwo sesilonda. Ngenxa yoshintsho olubukhali ekushiseni kweseli, ukwakheka kwekristalu ebusweni besakhiwo, ukuze ukuphelelwa amanzi emzimbeni kweseli, ukuncishiswa, ama-electrolyte nezinye izinguquko, ukubanda kungenza futhi izinga lokugeleza kwegazi lendawo lihambe kancane, ukuqina kwegazi noma i-embolism ebangelwa ukufa kwe-cell hypoxia.
Imishini ye-HL Cryogenic
Imishini ye-HL Cryogeniceyasungulwa ngo-1992 iwuphawu oluhambisana ne-Inkampani Yemishini Ye-HL Cryogenic Equipment Cryogenic Equipment Co.,LtdI-HL Cryogenic Equipment izibophezele ekwakhiweni nasekukhiqizweni kwe-High Vacuum Insulated Cryogenic Piping System kanye ne-Support Equipment ehlobene nayo ukuze kuhlangatshezwane nezidingo ezahlukene zamakhasimende. I-Vacuum Insulated Pipe kanye ne-Flexible Hose zakhiwe nge-vacuum ephezulu kanye nezinto ezifakwe i-multi-layer multi-screen ezikhethekile, futhi zidlula ochungechungeni lwezindlela zokwelapha zobuchwepheshe eziqinile kakhulu kanye nokwelashwa kwe-vacuum ephezulu, okusetshenziselwa ukudlulisa i-oxygen ewuketshezi, i-nitrogen ewuketshezi, i-argon ewuketshezi, i-hydrogen ewuketshezi, i-helium ewuketshezi, i-ethylene gas LEG kanye ne-LNG yegesi yemvelo ewuketshezi.
Uchungechunge lwemikhiqizo ye-Vacuum Valve, i-Vacuum Pipe, i-Vacuum Hose kanye ne-Phase Separator ku-HL Cryogenic Equipment Company, oludlule ochungechungeni lwezindlela zokwelapha zobuchwepheshe eziqinile kakhulu, lusetshenziselwa ukuthutha i-oxygen ewuketshezi, i-nitrogen ewuketshezi, i-argon ewuketshezi, i-hydrogen ewuketshezi, i-helium ewuketshezi, i-LEG kanye ne-LNG, futhi le mikhiqizo isetshenziselwa imishini ye-cryogenic (isb. amathangi e-cryogenic nama-flask e-dewar njll.) ezimbonini ze-elekthronikhi, i-superconductor, ama-chips, i-MBE, ikhemisi, i-biobank/cellbank, ukudla neziphuzo, ukuhlanganiswa kwe-automation, kanye nocwaningo lwesayensi njll.
