Kwimveliso yanamhlanje yokuchaneka, ukuchaneka akuyonto ibalulekileyo—yinto ebalulekileyo. Ukususela ekuhlolweni kwecandelo leenqwelo moya ukuya kwi-semiconductor lithography, izixhobo zokulinganisa ngokuchanekileyo zenza isiseko solawulo olunemilinganiselo. Phakathi kwezi zixhobo, izixhobo zegranite ziye zavela njengezinto ezisetyenziswa ngokuchanekileyo kwizicelo ezichanekileyo, ziphumelela ngaphezu kwentsimbi yendabuko kwiimilinganiselo zokusebenza ezibalulekileyo. Eli nqaku lihlola izizathu zobugcisa ezibangela ukuba igranite ilawuleke kwi-metrology kwaye lichaza isizathu sokuba iinkokheli zoshishino zitshintshe ukusuka kwintsimbi ukuya kwigranite.
Ukuguquka kwezinto zeMetrology: Ukusuka kwiNsimbi ukuya kwiGranite
Ngaphambi kweMfazwe Yehlabathi yesiBini, abavelisi babesebenzisa kakhulu iipleyiti zomphezulu wentsimbi ukuze bahlole ubukhulu becala. Nangona kunjalo, imfazwe yadala imfuno engakaze ibonwe yentsimbi, nto leyo eyakhokelela ekunyibilikeni ngokubanzi kweepleyiti zomphezulu wentsimbi ukuze kuveliswe umkhosi. Le ngxaki yanyanzela imboni ukuba ifune ezinye iindlela, kwaye i-granite yavela njengokhetho oluphezulu—isigqibo esasiza kuyila kwakhona imveliso echanekileyo ngonaphakade.
Olu tshintsho aluzange lube lolwethuba nje kuphela; lwalusekelwe kwiimpawu ze-metrological ze-granite. Abavelisi bafumanise ukuba i-granite inokudityaniswa ibe tyaba kakhulu kunentsimbi, inika uzinzo oluphezulu lobushushu, kwaye ayifuni ukugcinwa kakhulu. Ezi nzuzo ziye zabonakala ngakumbi njengoko ukunyamezelana kokwenziwa kwezinto kuye kwaqina ukusuka kwi-intshi enye ukuya kwi-microns kunye ne-nanometers.
Uzinzo lobushushu: Umahluko obalulekileyo
Ukuqonda Ukwanda Kobushushu kwiMetrology
Kwiindawo zokulinganisa ngokuchanekileyo, ukwanda kobushushu mhlawumbi yeyona nto ibalulekileyo echaphazela ukuchaneka. Nokuba ukuguquguquka okuncinci kobushushu kunokuvelisa utshintsho olulinganisekayo kubukhulu bezinto zentsimbi.
Umngeni we-Thermal we-Steel:
- I-Coefficient of Thermal Expansion (CTE): 11-13 µm/m·°C
- Ukutshintshatshintsha kobushushu obuyi-1°C kuphela kunokubangela impazamo yomgca eyi-0.01mm/m
