Mvura senitrogen tembiricha

Liquid senitrogen chinhu läpinäkyvä zvinhu ane arambe achirema chaiyo iri 0,808 g / cm³. Izvi - mumwe mamiriro aggregation iri rinogona kuva senitrogen, kubika tembiricha kuti -195,75 C. Liquid senitrogen haisi chepfu uye kuputika-uchapupu.

A chepfungwa kushanda uye kuchengetera emura senitrogen ndechokuti kana pakutsamwisana izvozvo anowedzera zvikuru Somuenzaniso, tembiricha unomutswa chete 20 C, mumwe fő zvinhu aumbwa anenge 700 litres negasi. Naizvozvo, chengetedzo uye kutakurwa anokosha midziyo yaro zvikashandiswa, anonzi Dewar midziyo izvo zvinopa Vacuum zindoga.

Liquid senitrogen iri ikabatwa zvikuru zvinowanzoshandiswa minda basa evanhu siyana, muzvinhu zvizhinji, zvikaita mamita zvakadai kushandiswa nokuda pfuma iyi, tembiricha emura senitrogen. Rinoshandiswa mumaindasitiri apo zvakakodzera kushandisa cryogenic michina rokutema simbi. A chaizvo pasi tembiricha emura senitrogen achibvumira kushandiswa kwayo zvakadzama-yakagwamba nechando, uye munda ichi zvakakodzera zvose inorganic zvinhu uye makemikari, kusanganisira zvipenyu.

Pane dzimwe mafomu dzinosanganisira: moto kurwa uye kutonhora zviyero siyana uye michina mano, cryopreservation masero overclocking.

Panguva mumhepo kumanikidzwa, mura senitrogen tembiricha pazasi condensation tembiricha reokisijeni pa 10 Zvisinei, madhigirii, ave mutemo, mudziyo pamadziro inogona kuchengetwa condensate fuma precipitate.

Nemhaka yokuti kubika pfungwa senitrogen iri mvura Hurumende - 195,8 C, iyo yakaderera pane kuti nemvura okisijeni pazviri - 183 C, nemhaka yavo nekuita emura mhepo vafumiswa pamwe okisijeni nokukurumidza. Izvi anotsanangura musiyano iri kutonhora uye zvikuru zviri kwemvura emura senitrogen, zvichienzaniswa mvura okisijeni.

Anoita chero tembiricha kuti runopfuura chakarurama kuti mvura senitrogen, inogona kuchengetwa pakuitisa zvinotevera kuedza. Essential iyi aruminiyamu nechigumbuso akanga dzaserera, kana zvishoma nezvishoma kuchadonha mvura mhepo.

In yazvino tembiricha emura senitrogen sezvo inokosha pfuma nezvinhu zvakakonzera kushandiswa kwakapararira munzvimbo zvemagetsi uye nemagetsi maindasitiri ose semiconductors, iyo nokudaro kuwana yakavimbika kutonhora.

On the ichocho, uye mafomu kunobva fuma somunhu chezvinonhuwira siyana moto wemisanganiswa. In muitiro ukabvisa senitrogen runopwa nokukurumidza uye, nokudaro, displaces yakachena, zvichiguma kugumiswa kuwana reokisijeni kuti moto moto moto vemunyika uye arega zvachose. Nokuda izvi nhasi senitrogen moto-kurwa Anonzi kunobatsira kupfuura kabhoni-dioxide. Kana kushandisa michina yakadaro, mukuru mwero ndichengetedze upfumi.

Kazhinji, zvinokonzerwa nemvura senitrogen anokwanisa kuongorora zvinenge ose, ukadzoka ayo pfungwa kupa kufirimu-zvakadai, yaishandiswa filming mafirimu panguva. Somuenzaniso, muna firimu 'The Terminator' zvinowanzoshandiswa Migumisiro vakawana nokushandisa mura senitrogen (mapuranga, iyo inoratidza pakarepo nechando zvivako). Asi izvi kunogona zvikuru vanongogara nomuvengi. Somuenzaniso, pasi tembiricha senitrogen rinobvumira kushandiswa kwayo nokuda kutsanya chando unonyaradza marwadzo hunhu. Izvi tinogona kazhinji kuchengeta panguva mumwe mutambo, kana mumhanyi wakuvadzwa, uye ake rubatsiro yokutanga kuburikidza yomunharaunda aerosol yokutindivadza.

More zvekumwe, kana asina naka, ikozvino anomira kushandiswa nefuma senzira nechando zvipenyu, tichifunga kwavakazoita defrosting, uye kuchengetedza utachiona zvivako.

Panguva iyoyowo, zvose muna US uye kuRussia, varipo kare makambani kuti vari kutengeswa mumabasa cryogenic nechando kwevanhu uye mhuka.
