Tooj liab tsis yog tsuas siv nyob rau hauv ib txwm muaj kev lag luam, tooj kuj xav kom koj nkag siab, tooj liab "," lub zog thev naus laus zis "thiab lwm yam kev lag luam. Aerospace technology ", 'lub zog siab physics' thiab lwm yam kev lag luam.
Koob piv tawj
Cov ntaub ntawv thev naus laus zis yog lub precursor ntawm kev siv thev naus laus zis. Nws tso siab rau lub crystallization ntawm cov tswv yim niaj hnub no - lub khoos phis tawm ua cov cuab yeej rau kev ua thiab tuav cov ntaub ntawv hloov pauv thiab dav dav. Lub plawv ntawm lub khoos phis tawm muaj microprocessor (muaj tus neeg teb xov tooj thiab maub los (controler) thiab nco. Cov khoom siv yooj yim (kho vajtse) yog cov loj-teev ua ke sib xyaw nrog lab nrog lab, tiv thaiv, faib rau ntawm cov chips me me. Peev xwm thiab muaj lwm yam los ua cov haujlwm ceev tshaj plaws, cov haujlwm tsim nyog thiab cov ntaub ntawv ntau. Lub chips ntawm cov kev sib xyaw ua ke no tau sib dhos los ntawm cov taug txhuas thiab luam tawm cov voj voog kom ua haujlwm. Los ntawm cov ntawv thov dhau los "hauv cov khoom siv hluav taws xob" Tshooj kev lag luam "tooj liab thiab tooj liab xwb tsis yog cov hmoov txhuas xwb thiab luam tawm cov khoom siv hluav taws xob ntawm cov ntaub ntawv tseem ceeb; Tab sis kuj nyob rau hauv lub colrcuitfation Circuitacation kuj tseem ua tau lub luag haujlwm tseem ceeb hauv kev sib tshuam ntawm cov khoom me me.
Superconductivity thiab cryogenics
Cov ntaub ntawv dav dav (tshwj tsis yog sinsonductors) tsis kam txo qis ntawm qee cov ntaub ntawv yuav ploj mus, ib qho tshwm sim uas hu ua superconductivity. Qhov kub tshaj plaws ntawm kev kub siab tshaj plaws uas yog superconductivity tshwm sim yog hu ua qhov tseem ceeb superconducting kub ntawm cov khoom. Kev tshawb nrhiav ntawm superconductivity qhib lub ntiaj teb tshiab rau kev siv hluav taws xob. Rov qab rau lub qhov tsis kam yog xoom, tsuav yog daim ntawv thov ntawm voltage me me heev tuaj yeem tsim ib qho chaw sib nqus heev) tam sim no, nkag mus rau ib qho kev sib nqus thiab sib nqus; Los yog thaum tam sim no los ntawm nws, tsis tshwm sim thaum lub voltage yog txo thiab poob ntawm lub zog hluav taws xob. Pom tseeb tias nws cov ntaub ntawv siv tswv yim yuav ua rau tib neeg hauv kev tsim khoom thiab lub neej ntawm kev hloov pauv, ntau tus neeg cov xim.
Tab sis rau cov hlau li ib txwm, tsuas yog thaum qhov kub yog qis dua rau qhov tsis tshua muaj xoom (}}} degree c) thaum lub tsev kawm ntawv qib siab, hauv kev tsim kho kom paub. Nyob rau hauv xyoo tsis ntev los no, qee cov alloys superoconduct tau tsim, lawv qhov tseem ceeb tshaj plaws yog siab dua li ntawm cov ntawv ntshiab rau 18.1 K. Tab sis lawv cov ntawv thov tsis tuaj yeem sib cais los ntawm tooj liab txhua lub sijhawm. Ua ntej tshaj plaws, cov alloys ua haujlwm ntawm ultra-tsawg helium kom tau txais cov roj li roj qis, piv txwv li cov kua kub: 20k (ib qho 257k (ib xyoo 196 degree c). Tooj liab nyob rau hauv xws li qhov kub tsawg tseem muaj cov khoom muaj zog zoo thiab muaj cov yas, yog qhov tseem ceeb hauv qhov ntsuas kub thiab txias thiab cov twj xa khoom. Ib qho ntxiv, NB3SN, NBTI thiab lwm cov alloys superoys muaj cov txheej txheem heev, yuav tsum tau siv tus qauv, yuav tsum tau siv tooj liab ua cov khoom siv lub tsho ua ke los sib xyaw ua ke. Cov ntaub ntawv superconducting tau siv los ua cov hlau nplaum muaj zog, hauv kev ntsuas mob nuclear Yog nyob rau hauv txoj kev npaj, ntau tshaj 500 mais hauv ib teev ceev ntawm cov ntawv sau sib tw rau cov tsheb ciav hlau, kom tsis txhob muaj kev tiv thaiv lub log tsheb, thiab paub qhov kev ua haujlwm siab ntawm cov ntoo.
Aerospace Tshuab
Rockets, satellites thiab qhov chaw shuttles, ntxiv rau cov cuab yeej siv me me, ntau cov khoom siv tseem ceeb, ntau cov cuab yeej tseem ceeb, ntau cov khoom siv tooj liab thiab tooj liab. Piv txwv li, lub zos sab hauv ntawm kev sib txuas thiab cov lag luam uas muaj lub cav hluav taws xob tuaj yeem txias ntawm cov hlau ua kom ntsuas kub. Lub zos sab hauv ntawm kev sib txuas ntawm cov armber ntawm Ariane 5 Rocket yog ua los ntawm tooj liab thiab kua kub ua ke yog dhau los mus txias lub foob pob hluav taws thaum nws tau tsim tawm. Ib qho ntxiv, Copper alloys yog cov khoom siv txheem siv rau cov khoom thauj khoom-cov kabmob hauv cov qauv satellite. Lub hnub ci ntsa iab ntawm satellites feem ntau yog ua los ntawm copper siv nrog ob peb lwm yam.
Siab Zog Physics
Tsis paub meej ntawm cov qauv ntawm teeb meem yog qhov tseem ceeb rau cov ncauj lus uas cov kws tshawb fawb tau mob siab. Txhua kauj ruam ntxaum hauv kev nkag siab ntawm cov teeb meem no muaj qhov cuam tshuam tseem ceeb rau tib neeg. Qhov kev siv tam sim no atomic zog yog rooj plaub hauv taw tes. Cov kev tshawb fawb tsis ntev los no tau qhia tawm tias cov tsev me me uas tsis yog molecules thiab absing thiab leptons, uas yog ntau txhiab lub sij hawm me dua. Kev tshawb fawb ntawm cov khoom lag luam ntoo no yog tam sim no nqa tawm ntawm kev ua tsis zoo ntawm lub sijhawm ntawm lub sij hawm atomic bomic tawg, thiab yog lub npe hu ua High-zog Physics. Xws li lub zog siab yog tau los ntawm "Bombarding" ib lub hom phiaj ruaj khov uas tau nrawm dua nyob rau hauv lub zog sib nqus (ntawm cov dej sib nqus Rau lub hom phiaj no, nws yog ib qho tsim nyog los tsim cov kev sib tw ntev ntev ntawm cov liaj sib xyaw muaj zog nrog cov hlau windings. Tsis tas li ntawd, ib qho qauv zoo sib xws yuav tsum muaj nyob rau hauv kev tswj thermonuccoar cov tshuaj tiv thaiv. Txhawm rau kom txo tau qhov kub kub nce siab vim yog cov kev hla dhau los ntawm cov loj loj, cov thau hluav taws xob rau cov pob tw loj dua los ntawm cov zaj hauv nruab nrab.
