Mapulatifomu olondola a granite, okhala ndi kulimba kwawo kwakukulu, kuchuluka kochepa kwa kukula, magwiridwe antchito abwino kwambiri oletsa kuzizira komanso mphamvu zachilengedwe zotsutsana ndi maginito, ali ndi phindu losasinthika pakugwiritsa ntchito m'magawo apamwamba opanga zinthu komanso kafukufuku wasayansi komwe kulondola ndi kukhazikika zimafunidwa kwambiri. Izi ndi zitsanzo zazikulu za momwe amagwiritsidwira ntchito komanso zabwino zake zaukadaulo:
I. Munda wa zida zopangira zinthu molondola kwambiri
Zipangizo zopangira semiconductor
Zochitika zogwiritsira ntchito: Tebulo la makina ogwiritsira ntchito Lithography, maziko a makina odulira ma wafer, nsanja yoyika zida zopakira.
Mtengo waukadaulo:
Chiŵerengero cha kutentha kwa granite ndi (0.5-1.0) ×10⁻⁶/℃ chokha, chomwe chingalepheretse kusinthasintha kwa kutentha panthawi ya makina a lithography (cholakwika cha kusamuka < 0.1nm pamalo a ±0.1℃).
Kapangidwe ka mkati mwa ming'alu yaing'ono imapanga damping yachilengedwe (damping ratio 0.05 mpaka 0.1), kuletsa kugwedezeka (amplitude < 2μm) panthawi yodula mwachangu ndi makina odulira ndikuwonetsetsa kuti m'mphepete mwa Ra ya wafer cutting ndi yochepera 1μm.
2. Makina Opera Molondola ndi Makina Oyezera Mogwirizana (CMM)
Nkhani yogwiritsira ntchito:
Pansi pa makina oyezera atatuwa pamakhala granite yokhazikika, yokhala ndi kusalala kwa ±0.5μm/m. Pophatikizidwa ndi njanji yoyendetsera mpweya, imakwaniritsa kulondola kwa kayendedwe ka nano-level (kulondola kobwerezabwereza malo ±0.1μm).
Tebulo logwirira ntchito la makina opukutira kuwala limagwiritsa ntchito kapangidwe ka granite ndi chitsulo chasiliva. Mukapukutira galasi la K9, kugwedezeka kwa pamwamba kumakhala kochepera λ/20 (λ=632.8nm), zomwe zimakwaniritsa zofunikira pakupanga magalasi a laser.
II. Munda wa Optics ndi Photonics
Ma telesikopu a zakuthambo ndi makina a laser
Ntchito wamba:
Nsanja yothandizira pamwamba pa kuwala kwa telesikopu yayikulu ya wailesi imagwiritsa ntchito kapangidwe ka granite uchi, komwe ndi kopepuka (kachulukidwe ka 2.7g/cm³) ndipo kumakhala kolimba polimbana ndi kugwedezeka kwa mphepo (kusintha < 50μm pansi pa mphepo ya 10-level).
Pulatifomu yowunikira ya laser interferometer imagwiritsa ntchito granite yokhala ndi porous granite. Chowunikiracho chimakhazikika ndi vacuum adsorption, ndi cholakwika cha flatness chosakwana 5nm, kuonetsetsa kuti kuyesa kwa ultra-precision optical monga kuzindikira mafunde okoka kumakhala kokhazikika.
2. Kukonza bwino zinthu zowunikira
Ubwino waukadaulo:
Kuchuluka kwa maginito ndi mphamvu zamagetsi pa nsanja ya granite kuli pafupi ndi zero, kupewa kukhudzidwa ndi kusokoneza kwa maginito pa njira zolondola monga kupukuta kwa ion beam (IBF) ndi kupukuta kwa magnetorheological (MRF). Kulondola kwa mawonekedwe a pamwamba pa lens ya asphical yokonzedwa kumatha kufika pa λ/100.
III. Kuwunika Zamlengalenga ndi Kulondola
Nsanja yowunikira zigawo za ndege
Zochitika Zogwiritsira Ntchito: Kuyang'ana masamba a ndege m'magawo atatu, kuyeza mawonekedwe ndi malo omwe zinthu zomwe zimapangidwa ndi aluminiyamu zimaloledwa kugwiritsidwa ntchito pa ndege.
Kuchita bwino:
Pamwamba pa nsanja ya granite imakonzedwa ndi dzimbiri la electrolytic kuti ipange mapangidwe abwino (okhala ndi kuuma kwa Ra 0.4-0.8μm), oyenera kugwiritsa ntchito ma trigger probes olondola kwambiri, ndipo cholakwika chozindikira mbiri ya tsamba ndi chochepera 5μm.
Imatha kupirira katundu woposa 200kg wa zida zoyendera ndege, ndipo kusintha kwa kusalala pambuyo pogwiritsidwa ntchito kwa nthawi yayitali kumakhala kochepera 2μm/m, zomwe zimakwaniritsa zofunikira pakukonza molondola kwa Giredi 10 mumakampani opanga ndege.
2. Kulinganiza kwa zigawo zoyendetsera za inertial
Zofunikira paukadaulo: Kulinganiza mosasunthika kwa zida zopanda mphamvu monga ma gyroscope ndi ma accelerometer kumafuna nsanja yowunikira yokhazikika kwambiri.
Yankho: Nsanja ya granite imaphatikizidwa ndi makina ogwirira ntchito odzipatula ogwedezeka (mafupipafupi achilengedwe < 1Hz), zomwe zimapangitsa kuti pakhale kulinganiza kolondola kwambiri kwa kukhazikika kwa zero-offset kwa zigawo za inertial < 0.01°/h m'malo okhala ndi kugwedezeka kofulumira < 1×10⁻⁴g.
Iv. Nanotechnology ndi Biomedicine
Pulatifomu ya microscope (SPM) yojambulira
Ntchito yaikulu: Monga maziko a atomic force microscopy (AFM) ndi scanning tunneling microscopy (STM), iyenera kuchotsedwa ku kugwedezeka kwa chilengedwe ndi kutentha.
Zizindikiro za magwiridwe antchito:
Pulatifomu ya granite, pamodzi ndi miyendo yodzipatula ya pneumatic vibration, imatha kuchepetsa kuchuluka kwa kufalikira kwa kugwedezeka kwakunja (1-100Hz) kufika pa 5%, zomwe zimapangitsa kuti AFM ijambulidwe pamlingo wa atomiki mumlengalenga (resolution < 0.1nm).
Kuzindikira kutentha ndi kochepera 0.05μm/℃, zomwe zimakwaniritsa zofunikira pakuwunika zitsanzo zamoyo mu kutentha kosasintha (37℃±0.1℃).
2. Zipangizo zopakira za Biochip
Mkhalidwe wogwiritsira ntchito: Pulatifomu yolondola kwambiri yolumikizira ma tchipisi a DNA imagwiritsa ntchito njanji zowongolera zoyandama za granite air-floating, zokhala ndi kulondola kwa malo a ±0.5μm, kuonetsetsa kuti sub-micron ikugwirizana pakati pa njira ya microfluidic ndi electrode yozindikira.
V. Zochitika Zoyambira Kugwiritsa Ntchito
Zida zamakompyuta za quantum
Mavuto aukadaulo: Kusintha kwa Qubit kumafuna kutentha kochepa kwambiri (mK level) komanso malo okhazikika kwambiri amakina.
Yankho: Mphamvu yokulirakulira ya granite yotsika kwambiri (kuchuluka kwa kukula < 1ppm kuchokera -200℃ mpaka kutentha kwa chipinda) ikhoza kufanana ndi mawonekedwe a maginito a superconducting otentha kwambiri, ndikuwonetsetsa kuti ma quantum chips akulondola.
2. Dongosolo la Electron Beam Lithography (EBL)
Kagwiridwe kake ka ntchito: Kapangidwe ka kutenthetsa kwa pulatifomu ya granite (resistivity > 10¹³Ω · m) kamaletsa kubalalika kwa electron beam. Pophatikizidwa ndi electrostatic spindle drive, imakwaniritsa kulemba kwapamwamba kwa lithography pattern yokhala ndi nanoscale line width (< 10nm).
Chidule
Kugwiritsa ntchito nsanja zolondola za granite kwafalikira kuyambira pa makina olondola achikhalidwe mpaka m'magawo apamwamba monga nanotechnology, quantum physics, ndi biomedicine. Mpikisano wake waukulu uli mu kulumikizana kwakukulu kwa zinthu zakuthupi ndi zofunikira za uinjiniya. M'tsogolomu, ndi kuphatikiza matekinoloje olimbitsa ophatikizika (monga graphene-granite nanocomposites) ndi matekinoloje anzeru ozindikira, nsanja za granite zidzadutsa m'njira zolondola za atomiki, kukhazikika kwa kutentha konse, ndi kuphatikiza kwa ntchito zambiri, kukhala zigawo zazikulu zothandizira m'badwo wotsatira wa kupanga kolondola kwambiri.
