Los ntawm Kev Siv Hauv Chav Kuaj Mob mus rau Orbital Staple
Kev ziab kom khov (lyophilization) khaws cov khoom noj los ntawm kev tshem tawm cov dej noo thaum nws tseem khov, tiv thaiv cov cell lwj thiab pab khaws cov xim, cov duab, thiab cov as-ham. Txoj kev no tau hloov pauv los ntawm kev siv tshuaj mus rau hauv cov khoom noj thiab tom qab ntawd mus rau hauv kev ya mus rau hauv ntiaj teb tib neeg ua cov lus teb rau qhov hnyav, ntim, thiab kev nyab xeeb.
Cov kev pab cuam thaum ntxov tau teeb tsa cov qauv nruj heev - lub sijhawm khaws cia hauv chav sov, lub cev me me, qhov hnyav tsawg, thiab kev npaj sai thiab tsis tas siv zog ntau. Cov txheej txheem khaws cia uas NASA tau tshuaj xyuas suav nrog kev qhuav dej, kev ziab kom qhuav, qhov nruab nrab noo noo, kev siv tshuaj tua kab mob, thiab kev ntim nitrogen. Cov neeg ua haujlwm hauv lub sijhawm Mercury tau sim cov thawv me me, cov hmoov qhuav kom qhuav, thiab cov kua ib nrab, uas nyuaj rau rov ua kom dej rov qab thiab tsim cov khoom me me uas ntab hauv qhov hnyav me me.[1]
Vim li cas cov neeg caij dav hlau tseem siv nws
Los ntawm kev tshem tawm yuav luag tag nrho cov dej, cov zaub mov khov qhuav txo qhov hnyav ntawm lub dav hlau, ntev lub txee lub neej yam tsis tas yuav txias, thiab rov ua kom dej rov qab siv cov khoom siv tsawg kawg nkaus - cov txiaj ntsig uas tseem ceeb txawm tias cov galleys niaj hnub no zoo dua. Piv txwv li, ntawm Chaw Nres Nkoj Thoob Ntiaj Teb, cov neeg ua haujlwm yuav muaj lub tub yees thiab qhov cub, tab sis cov zaub mov khov qhuav thiab cov zaub mov sab tseem yog ib feem ntawm cov zaub mov sib xyaw vim lawv qhov kev ntseeg tau thiab kev ua haujlwm zoo.[1]
Kev npaj rau dej txias:NASA tau teem ib lub hom phiaj rau cov khoom noj kom rov ua dua hauv dej li ntawm 80°F (27°C) hauv 10 feeb; cov kua zaub tshwj xeeb uas tsim tshwj xeeb tau mus txog qhov dej rov qab tag nrho hauv li ntawm 5 feeb.[1]
Yuav Ua Li Cas Khov-Qhuav Ua Haujlwm
Khoom noj raug khov (kwv yees li −40°F), muab tso rau hauv lub tshuab nqus tsev, thiab maj mam ua kom sov kom dej khov hla dhau theem kua thiab hloov mus ua pa (sublimation). Cov pa dej raug tshem tawm thiab lub voj voog rov ua ntau zaus kom txog thaum cov khoom qhuav. Lub voj voog ib txwm kav li 8–24 teev thiab tuaj yeem tshem tawm ntau dua 99% ntawm cov dej qub.[1]
Kev Noj Haus, Kev Zoo Nkauj, thiab Kev Saj
Vim tias kev khov ua rau cov khoom noj muaj cov qauv zoo thaum lub sijhawm ziab, cov khoom uas tau rov ua kom dej noo tuaj yeem khaws cov qauv thiab saj zoo nkauj. Piv nrog rau kev ziab dej ib txwm muaj, uas feem ntau tshem tawm ~ 92–96% ntawm cov dej noo, kev ziab khov ntau dua 99% tshem tawm ua rau cov pob khoom sib dua, rov ua kom dej noo sai dua, thiab khaws cov zaub mov thiab lwm yam khoom noj zoo dua.[1]
Lus Cim Txog Kab Lis Kev Cai: Qhov Tseeb Txog "Astronaut Ice Cream"
Cov khoom qab zib khov qhuav nto moo tau pib ua ib yam tshiab rau pej xeem pom hauv xyoo 1973 uas txuas nrog Ames Visitor Center. Nws siv cov kev nce qib hauv kev ua haujlwm hauv ntiaj teb tab sis tsis yog cov khoom noj rau cov neeg caij nkoj. Txawm li cas los xij, zaj dab neeg no tau pab ua rau cov khoom qab zib khov qhuav nrov nrog cov neeg mus saib tsev khaws puav pheej thiab cov neeg nyiam ua si sab nraum zoov.[1]
Tom ntej no yog dab tsi
Saib mus tom ntej, kev tshawb fawb tsom mus rau cov qauv ziab ntse dua kom rov qab tau dej sai dua, sib npaug dua, ruaj khov micronutrient, thiab cov zaub mov tshwj xeeb rau lub hom phiaj. Lub hom phiaj yog ib yam uas peb paub zoo: kev noj zaub mov zoo tshaj plaws thiab kev txhawb siab, qhov hnyav tsawg tshaj plaws thiab kev pov tseg.
Cov Lus Nug Feem Ntau
Dab tsi ua rau cov khoom noj khov qhuav nyiam rau kev ya mus rau saum ntuj thaum ntxov?
Lawv haum rau qhov luv luv: ruaj khov rau ntawm chav tsev kub, me me, tsis hnyav, thiab yooj yim npaj nrog me ntsis dej lossis khoom siv - zoo tagnrho rau kev ua haujlwm microgravity.
Kev ziab kom qhuav txawv li cas ntawm kev ziab kom qhuav ib txwm muaj?
Kev ziab kom qhuav tshem tawm ~ 92–96% ntawm cov dej; kev ziab kom qhuav tshem tawm > 99%. Qhov tshwm sim yog cov khoom thauj sib dua, rov ua kom qhuav sai dua, thiab feem ntau khaws cov as-ham zoo dua.
Cov neeg caij dav hlau puas noj cov ice cream uas khov qhuav tiag?
Tsis yog - nws tau pib xyoo 1973 ua ib qho khoom tshiab hauv tsev khaws puav pheej uas txuas nrog NASA's Ames Visitor Center es tsis yog ua zaub mov rau qhov chaw.
Cov txheej txheem no muaj dab tsi?
Khov kom txog li -40°F, siv lub tshuab nqus tsev, ntxiv cua sov maj mam kom dej khov ua pa, rov ua dua kom txog thaum dej ploj tag (feem ntau tshaj 8–24 teev).
Cov neeg ua haujlwm puas tuaj yeem haus dej txias kom rov qab haus cov zaub mov tau?
Yog. NASA tsom rau ~80°F (27°C) dej nrog lub sijhawm 10 feeb; cov mis tshwj xeeb xws li cov kua zaub ua rau ~5 feeb.
