Unxibelelwano olungenasiphelo phakathi kwe-white corundum kunye netekhnoloji yexesha elizayo
Wonke umntu kwisangqa sobuchwepheshe uyazi ukuba izinto ezintsha ziyimali ethembekileyo. Ngubani obenokucinga ukubai-corundum emhlophe, ebonakala ngathi yiswekile emhlophe, iya kuba “ngumkhuthazi ongabonakaliyo” wenguquko yetekhnoloji yexesha elizayo. Ukusuka kwiitships zefowuni eziphathwayo ukuya kwiindawo zeMars rover, ukusuka kwiikhompyutha ze-quantum ukuya kwizixhobo ze-fusion zenyukliya ezilawulwayo, inokufumaneka kuyo yonke indawo. Namhlanje, masikhulule olu maleko lwetekhnoloji size sibone indlela eli gcisa lezemveliso elenza ngayo izinto ezinkulu ngokuthula.
1. "Ijini yeteknoloji" enesiphiwo
Iimpawu ze-corundum emhlophe eziqinileyo zenzelwe nje ubuchwepheshe bexesha elizayo. Ngobunzima be-Mohs obuyi-9.0, umoya wayo umbi kakhulu kunedayimani. Umzi-mveliso womatshini we-photolithography eShanghai wenze uvavanyo lokuthelekisa. Uburhabaxa bomphezulu wereyile ekhokelayo epholishwe nge-corundum emhlophe bunokufikelela kwi-Ra0.008μm. Ingcali uXiao Li ubambe isixhobo somsebenzi waza wabetha imilebe yakhe: “Ngale ndlela ichanekileyo, ingcongconi ingaphula ithambo ukuba ima phezu kwayo!”
Ukuzinza kobushushu kuyamangalisa nangakumbi. Idatha evela kwilebhu yokudibanisa inyukliya elawulwayo eQingdao ibonise ukuba iiseramikhi ezimhlophe ezisekwe kwi-corundum zikwazile ukumelana nobushushu obuphezulu be-2000℃ kangangeeyure ezili-100, kwaye utshintsho lobukhulu belungaphantsi kwe-0.01%. Umphandi uLao Wang wabetha igumbi lokucoca umoya waza wathi: “Le nto inokuma phezu kwelanga kangangeentsuku ezimbini!”
2. “Iintshatsheli ezifihlakeleyo” kwiCandelo leSemiconductor
Kwidabi le-nano-scale lokuvelisa iitships, i-white corundum ibisoloko “ingumlandeli okhukulayo”. Umzi-mveliso we-wafer eTaizhou usebenzise i-0.1μm white corundum micro-powder ukusika ii-silicon wafers, kwaye izinga lokuwa komphetho lehliswa laya kwi-0.2‰. UMaster Lao Chen wajonga i-microscope waza wahleka: “Ngoku ukusika ii-wafers kusebenza ngcono kunokusika i-tofu, kwaye izinga lemveliso lifikelela ngqo kwi-99.98%!”
Ukupholishwa kwelensi yomatshini we-lithography kuyinyani nangakumbi. Idatha evela kwilebhu eBeijing iyamangalisa: ilensi iphathwa ngolwelo olumhlophe lwe-corundum nano-polishing, kwaye ubume bomphezulu bufikelela kwi-λ/50 wavelength. UMlawuli wezoBugcisa uLao Liu wabonisa isandla sakhe wathi: “Olu lwazi lufana nokufaka isipili seplane kuLwandlekazi lwePasifiki!”
3. “Ukumkani woxinzelelo” kwiShishini leeNqwelo-moya
I-corundum emhlophe inelizwi lokugqibela ekucutshungulweni kweendawo ze-Mars rover. Umzi-mveliso othile wezixhobo zeenqwelo-moya eXi'an usebenzisa amavili okugaya e-corundum amhlophe ukugawula izibiyeli ze-titanium alloy, kwaye uxinzelelo oluseleyo lomphezulu lulawulwa lufikelela kwi-±5MPa. Injineli eyiNtloko uLao Zhang uthe ephethe icuba emlonyeni wakhe: “Ngalo mgangatho, uMusk kufuneka adlulisele icuba ukuze acele ingcebiso!”
Iiblade zeenjini zeenqwelo-moya zifikelele kwinqanaba elitsha. Idatha yenkampani ethile yeenjini zeenqwelo-moya eChengdu inomtsalane: iiblade ezimhlophe ezisekwe kwi-ceramic ze-corundum ezimhlophe, ezinokumelana nobushushu obufikelela kwi-1600℃. Umqhubi wovavanyo uLao Li wajonga kwideshibhodi waza wavuza amathe: “Ngalo msebenzi, iinjini zejethi kufuneka zibize utata!”
4. "Isiqinisekiso sokunyamezela" kwiNdlela entsha yamandla
I-corundum emhlophe ilungile kakhulu ekunqumleni iziqwenga zeepali zebhetri yamandla. Umzi-mveliso webhetri eNingde ulinganise: usebenzisa ucingo lwesanti ye-corundum emhlophe ukusika i-graphene coatings, ukuphakama kwe-burr kulawulwa ukuya ngaphantsi kwe-0.5μm. Umlawuli weworkshop uLao Zhou wabetha iseli yebhetri waza wathi ngovuyo: “Ubuninzi bamandla ale bhetri bungcono kuneTesla!”
5. "Imboniso yeTekhnoloji yabaNtsundu" yeXesha elizayo leMfazwe yeMfazwe
I-White corundum ilungile ekupholiseni iikhompyutha ze-quantum. Ilebhu eHefei iphuhlise ifilimu yokuqhuba ubushushu ye-corundum emhlophe ene-nano-scale enokuqhuba ubushushu be-400W/m·K. Umphandi uLao Ma waqhayisa wathi: “Ngoku ukusasazwa kobushushu kwee-quantum bits kukhawuleza kunokusebenzisa i-fever patch!”
Izinto zokuqala zodonga lwe-nucleus fusion zinamandla aqinileyo. I-white corundum composite ceramic yesikhungo sophando eMianyang inomlinganiselo womonakalo we-neutron irradiation ophindwe kathandathu kunezinto zemveli. Injineli eyiNtloko uLao Zhao wakhomba kwi-reactor wathi: “Ezi zinto ngokuqinisekileyo ziya kuhlala zizinzile de i-reactor yorhwebo ibekwe kwimveliso!”
