Liquid nitrogen: Nitrogen gasi iri mumvura. Inert, isina ruvara, isinganhuhwi, isingaore, isingabatike, yakanyanya cryogenic tembiricha. Nitrogen inoumba huwandu hwemhepo (78.03% nehuwandu uye 75.5% nehuremu).Nitrogen haishande uye haitsigire kupisa. Frostbite inokonzerwa nekunyanyisa endothermic kubata panguva yekupisa.
Liquid nitrogen inzvimbo inotonhora inotonhora. Nekuda kwehunhu hwayo hwakasiyana, nitrogen yemvura yakabhadharwa zvishoma nezvishoma uye ichizivikanwa nevanhu. Yave ichinyanya kushandiswa zvakanyanya mukupfuya mhuka, indasitiri yezvokurapa, indasitiri yechikafu, uye cryogenic research fields. Mune zvemagetsi, simbi, aerospace, kugadzira michina uye zvimwe zvinhu zvekushandisa zvave kuwedzera nekusimudzira.
Liquid nitrogen cryogenic microbial collection hunyanzvi
Nheyo yemvura nitrogen yekuunganidza zvachose nzira, iyo inounganidza mabhakitiriya marudzi pa -196 ℃, ndeyekuunganidza tupukanana zvinobudirira nekutora mukana weiyo tsika yekumisa metabolism yezvipembenene pazasi -130 ℃.Macrofungi iboka rakakosha refungi (fungi inoumba miviri mikuru inobereka michero mufungi, kazhinji ichireva howa kana howa nenzira yakafara). Mhuka zhinji dzine mutengo wakakwira wekudya uye mitengo yemishonga, uye vane tariro yekushandiswa inovimbisa pakati pefungi. Pamusoro pezvo, mamwe fungi akakura anogona kuongorora zvidyarwa zvakafa, izvo zvinotora basa rakakosha kuchengetedza kutenderera kwechisikigo uye kuenzana kwezvakatipoteredza, uye zvinogona kuvandudzwa uye kuiswa kuindasitiri yemapepa nekucheneswa kwezvakatipoteredza. Imwe fungi yakakura inogona kukonzera zvirwere zvemiti kana kukuvadza zvakasiyana-siyana zvemiti yemiti. Kuwedzeredzwa kwekunzwisisa kweiyi pathogenic fungi inobatsira kudzivirira uye kubvisa kukuvadza. Muunganidzwa wemuenzaniso wemacrofungi wakakosha zvikuru kunyarara uye kuunganidzwa kwezviwanikwa zvipenyu zvipenyu, muunganidzwa usingaperi uye unobatsira wezviwanikwa zvemajini, uye kugoverana kwezvipenyu munzvimbo dzakasiyana.
Kupona kweGenetic kwezvipenyu zvekurima
Shanghai yakaisa mari inodarika mamirioni makumi mana nerimwe eyuan kumisikidza uye kuendesa dhatabhesi yakazara yezvekurima biological genes muChina. Indasitiri yembeu, iyo ine mukana wekuvhura musika wepasi rose, ichashandisa bhanga remajini senzvimbo yekuberekesa, indasitiri yezvekurima yakadaro. Iyo Shanghai Agricultural Biological gene Bank, ine nzvimbo yakazara ye3,300 square metres, ichave iri muShanghai Academy yeAgricultural Sayenzi. Ichaunganidza marudzi mashanu ezvekurima biological genetic zviwanikwa zvinosanganisira mbeu dzezvirimwa, chirimwa extracellular zvinhu, masero ekubereka emhuka, hutachiona hwehutachiona uye chirimwa genetic engineering zvinhu.

Kukurumidza kukura kwekiriniki yemishonga ye cryogenic yakakurudzira kugadzirwa kwemishonga yekuisa, kunyanya mumwongo, masero eropa, ganda, cornea, mukati meganda remukati, tsinga dzeropa uye mavharuvhu, nezvimwewo. stem masero. Mukutonhodza uye kutonhora kwemasamples ebhayoloji, panguva yekuchinja kubva pamvura kuenda kune yakasimba, kumwe kupisa kunoburitswa uye tembiricha yacho inokwira. Kutonhora kwechando pasina kudzora mwero wekutonhora kunotungamira kurufu rwemaseru ekuumbwa. Kiyi yekuvandudza mwero wekupona kwemasampu akaomeswa nechando ndeyekunyatsoona chikamu chekuchinja kweiyo biological samples uye kushandisa microcomputer kutonhodza nhanho kuitira kuti uwedzere huwandu hwemvura yenitrogen yekuisa panguva yekuchinja kwechikamu, kudzvanya kukwira kwekushisa. chikamu chekuchinja sampuli uye kuita kuti masero apfuure chikamu chinje chinyararire uye nekukurumidza.
Mushonga wekiriniki
Liquid nitrogen ndiyo firiji inoshandiswa zvakanyanya mu cryosurgery. Ifiriji yakagadzirwa kusvika ikozvino, uye kana iwe ukaibaya muchirongwa chekurapa che cryogenic, inoita senge scalpel, uye unogona kuita chero kuvhiya. Cryotherapy kurapwa kunoshandisa tembiricha ye cryogenic kuputsa chimiro cheronda. Nekuda kwekuchinja kwakapinza kwekushisa kwesero, kuumbwa kwekristaro muchimiro chepamusoro, kuitira kuti sero kupera simba, shrinkage, electrolytes uye dzimwe shanduko, kutonhora kunogonawo kuita kuti kuyerera kweropa kunonoke, kuderera kweropa kana embolism. sero hypoxia kufa.
