Kev sib txuas tsis kawg ntawm cov corundum dawb thiab thev naus laus zis yav tom ntej
Txhua tus neeg hauv lub voj voog thev naus laus zis paub tias cov khoom siv tshiab yog cov nyiaj txiag ruaj khov. Leej twg yuav xav tiasdawb corundum, uas zoo li qab zib dawb, yuav dhau los ua "tus neeg txhawb nqa tsis pom" ntawm kev hloov pauv thev naus laus zis yav tom ntej. Txij li cov chips xov tooj ntawm tes mus rau Mars rover qhov chaw, los ntawm cov khoos phis tawj quantum mus rau cov khoom siv nuclear fusion tswj hwm, nws tuaj yeem pom txhua qhov chaw. Niaj hnub no, cia peb tshem tawm cov txheej txheem thev naus laus zis no thiab saib seb tus qub tub rog kev lag luam no ua tej yam zoo li cas ntsiag to.
1. Tus neeg muaj txuj ci "technology gene"
Cov khoom tawv ntawm cov corundum dawb tsuas yog tsim los rau kev siv tshuab yav tom ntej. Nrog Mohs hardness ntawm 9.0, nws tsuas yog ua pa phem dua li pob zeb diamond. Lub Hoobkas tshuab photolithography hauv Shanghai tau ua qhov kev sim sib piv. Qhov roughness ntawm qhov chaw ntawm cov lus qhia rail polished nrog dawb corundum tuaj yeem ncav cuag Ra0.008μm. Tus kws tshaj lij Xiao Li tuav lub workpiece thiab smacked nws daim di ncauj: "Nrog qhov kev ua kom raug no, tus yoov tshaj cum yuav tawg pob txha yog tias nws sawv ntawm nws!"
Qhov kev ruaj khov ntawm thermal tseem ceeb dua. Cov ntaub ntawv los ntawm lub chaw kuaj mob nuclear fusion hauv Qingdao qhia tau hais tias cov khoom siv ceramic dawb corundum tiv taus qhov kub siab ntawm 2000 ℃ rau 100 teev, thiab qhov hloov pauv loj tsawg dua 0.01%. Tus kws tshawb fawb Lao Wang tau kov lub chamber nqus tsev thiab hais tias: "Cov khoom no tuaj yeem sawv ntawm qhov chaw ntawm lub hnub rau ob hnub!"
2. "Cov Neeg Sib Tw Zais Cia" hauv Kev Lag Luam Semiconductor
Hauv kev sib ntaus sib tua ntawm nano-scale ntawm kev tsim cov chips, cov corundum dawb tau ntev los ua "tus thawj coj loj". Lub Hoobkas wafer hauv Taizhou siv 0.1μm dawb corundum micro-hmoov los txiav silicon wafers, thiab qhov nrawm ntawm ntug tawg tau txo qis rau 0.2‰. Xib Hwb Lao Chen ntsia lub tshuab microscope thiab luag: "Tam sim no txiav wafers zoo dua li txiav tofu, thiab qhov nrawm ntawm cov txiaj ntsig yog ncaj qha mus txog 99.98%!"
Qhov kev txhuam ntawm lub tshuab lithography lens yog qhov tseeb dua. Cov ntaub ntawv los ntawm lub chaw kuaj mob hauv Beijing yog qhov ua rau neeg xav tsis thoob: lub lens tau kho nrog cov kua dawb corundum nano-polishing, thiab qhov chaw tiaj tus yog txog li λ / 50 wavelength. Tus Thawj Coj Kev Txawj Ntse Lao Liu tau taw tes thiab hais tias: "Qhov kev ua kom raug no sib npaug rau kev teeb tsa daim iav dav hlau ntawm Dej Hiav Txwv Pacific!"
3. "Tus Vaj Ntxwv Compression" hauv Kev Lag Luam Aerospace
Dawb corundum muaj qhov kawg hauv kev ua cov khoom Mars rover. Ib lub Hoobkas khoom siv aerospace hauv Xi'an siv cov log sib tsoo dawb corundum los sib tsoo titanium alloy brackets, thiab qhov kev ntxhov siab seem ntawm qhov chaw raug tswj kom tsis pub dhau ± 5MPa. Tus Thawj Coj Kws Ua Haujlwm Lao Zhang hais nrog ib tug luam yeeb hauv nws lub qhov ncauj: "Nrog rau qib no, Musk yuav tsum tau hla ib tug luam yeeb kom thov kev qhia!"
Cov hniav ntawm lub cav aerospace tau mus txog qhov siab tshiab. Cov ntaub ntawv ntawm ib lub tuam txhab cav aviation hauv Chengdu yog qhov muag pom tseeb: cov hniav dawb corundum ceramic-based composite, nrog rau qhov kub thiab txias txog li 1600 ℃. Tus neeg tsav tsheb kuaj Lao Li ntsia lub dashboard thiab ntuav: "Nrog rau qhov kev ua tau zoo no, cov cav dav hlau yuav tsum hu ua txiv!"
4. "Kev Lav Paub Txog Kev Ua Siab Ntev" hauv Txoj Kev Siv Hluav Taws Xob Tshiab
Cov pob zeb corundum dawb zoo heev rau kev txiav cov ncej roj teeb fais fab. Lub Hoobkas roj teeb hauv Ningde ntsuas: siv cov hlau xuab zeb corundum dawb los txiav cov txheej graphene, qhov siab ntawm burr raug tswj kom qis dua 0.5μm. Tus thawj coj ntawm lub rooj cob qhia Lao Zhou tau kov lub roj teeb thiab hais zoo siab tias: "Lub zog ceev ntawm lub roj teeb no zoo dua li Tesla!"
5. "Kev Saib Ua Ntej Txog Kev Siv Tshuab Dub" ntawm Kev Sib Ntaus Sib Tua Yav Tom Ntej
Cov corundum dawb zoo rau kev txias cov khoos phis tawj quantum. Ib lub chaw kuaj mob hauv Hefei tau tsim ib daim zaj duab xis thermal conductive dawb corundum nano-scale nrog lub thermal conductivity ntawm 400W / m·K. Tus kws tshawb fawb Lao Ma tau khav theeb tias: "Tam sim no qhov cua sov ntawm cov quantum bits sai dua li siv daim ntawv kub taub hau!"
Cov khoom siv phab ntsa thawj zaug ntawm kev sib xyaw ua ke ntawm nuclear yog lub zog tawv dua. Cov khoom siv corundum dawb sib xyaw ua ke ntawm lub koom haum tshawb fawb hauv Mianyang muaj qhov ntsuas kev puas tsuaj ntawm neutron irradiation uas siab dua 6 npaug ntawm cov ntaub ntawv ib txwm muaj. Tus Thawj Coj Kws Ua Haujlwm Lao Zhao taw tes rau lub reactor thiab hais tias: "Cov khoom siv no yuav ruaj khov kom txog thaum lub reactor lag luam raug muab tso rau hauv kev tsim khoom!"
