Phambi kwemveliso echanekileyo kunye nophononongo lophando lwezenzululwazi, yonke impazamo inokuba "ngumqobo wendlela" othintela impumelelo. Njengesixhobo esiphambili sokufezekisa ulawulo lwentshukumo oluchanekileyo, ukusebenza kokuchaneka kwe-static yoxinzelelo lomoya ojikelezayo weqonga lentshukumo lihambelana ngqo nomgangatho kunye nempumelelo yeziphumo. Phakathi kwezinto ezininzi ezichaphazelayo, isiseko segranite, esineempawu ezingenakulinganiswa, sibe yinto ephambili yokuqinisekisa ukusebenza kakuhle kweqonga.
I-Granite, emva kwezigidi zeminyaka yokutshintsha kwejoloji inomsindo, isakhiwo sangaphakathi sixinene kwaye sifana, ngokukodwa nge-quartz, i-feldspar kunye nezinye iiminerali ezidibeneyo. Esi sakhiwo esiyingqayizivele esenziwe ngokwemvelo sinika isiseko segranite uluhlu lweempawu ezibalaseleyo.
Izinze kakhulu, ibekwe yodwa kuphazamiseko lwangaphandle
Ukungcangcazela kwimeko yangaphandle lutshaba lokuchaneka kokuchaneka kweqonga loxinzelelo oluzinzileyo lomoya oludadayo. Ukungcangcazela okuveliswe kukusebenza koomatshini abakhulu kunye nezixhobo kumgangatho wefektri kunye nezithuthi ezijikelezileyo zinokugqithiselwa kwiqonga elishukumayo emhlabeni. Nangona kunjalo, isiseko segranite sifana "nenqaba eqinileyo yokumelana neenyikima." Isakhiwo sayo sekristale esiyinkimbinkimbi sinokuthintela ngokufanelekileyo kwaye sinciphise ukungcangcazela, kwaye ngokusebenzisa iimvavanyo eziphathekayo, i-vibration amplitude ethunyelwa kwiqonga ingancitshiswa ngaphezu kwe-80%. Kwindibano yocweyo yokwenziwa kwetshiphu ye-semiconductor, inkqubo ye-photolithography ifuna ukuchaneka kokubeka ukufikelela kwinqanaba le-nanometer, kwaye iqonga elichanekileyo le-static yoxinzelelo lomoya elidadayo elixhaswa yisiseko segranite linokuqinisekisa ukusebenza okuzinzileyo kwezixhobo ze-chip lithography kwindawo yokungcangcazela entsonkothileyo, ugqibezele ngokuchanekileyo umkrolo wepateni yesekethe, kwaye uphucule kakhulu isivuno se-chip.
Ukuzinza okuhle kwe-thermal, ungesabi ukutshintsha kweqondo lokushisa
Ukutshintsha kweqondo lokushisa kuya kubangela ukuba izinto ezininzi zandise kwaye zinciphise, eziza kuchaphazela ukuchaneka kwezixhobo. Nangona kunjalo, isiseko segranite sibonisa ukuzinza okungaqhelekanga kwe-thermal, kwaye i-coefficient yayo yokwandiswa kwe-thermal iphantsi kakhulu, ngokubanzi kwi-5-7 × 10⁻⁶/℃. Kwinkalo ye-astronomy, iqonga elichanekileyo le-static yoxinzelelo lomoya odadayo elisetyenziselwa ukulungiswa kakuhle kweelensi ezinkulu zeteleskopu, kunye nesiseko segranite, nokuba kukho utshintsho olukhulu kumahluko wobushushu phakathi kwemini nobusuku, inokuqinisekisa ukuba ukuchaneka kokumiswa kwelensi kugcinwa kwinqanaba le-micron, inceda izazi ngeenkwenkwezi ukuba zibambe ngokucacileyo utshintsho olufihlakeleyo lwesibhakabhaka kunye nokuphonononga utshintsho olufihlakeleyo lwesibhakabhaka.
Ubunzima obuphezulu kunye nokumelana nokugqoka ukuqinisekisa ukusetyenziswa kwexesha elide
Ngexesha elide lokuchaneka kweqonga loxinzelelo lwe-static lomoya odadayo, nangona kukho inkxaso yomoya edadayo phakathi kweqonga kunye nesiseko, kusekho inqanaba elithile lokukhuhlana. Ubunzima be-Granite buphezulu, ubunzima be-Mohs bunokufikelela kwi-6-7, kunye nokumelana nokunxiba okugqwesileyo. Kwilabhoratri yezenzululwazi yezinto ezisetyenziswa rhoqo, iqonga lentshukumo yoxinzelelo lwestatic ethe tyaba yomoya, isiseko sayo segranite sinokuxhathisa ngempumelelo ilahleko yexesha elide, xa kuthelekiswa nesiseko esiqhelekileyo, inokwandisa umjikelo wokugcinwa kweqonga ngaphezulu kwama-50%, ukunciphisa iindleko zokugcina izixhobo, kunye nokuqinisekisa ukuqhubeka komsebenzi wophando lwezenzululwazi.
Ukhetho lwesiseko segranite soxinzelelo oluchanekileyo lweqonga lomoya odadayo lolona sukelo lokugqibela lokuchaneka, uzinzo kunye nokuqina. Kwimimandla yokuveliswa kwe-semiconductor, ukuveliswa kwesixhobo sokukhanya, i-aerospace, uphando lwezenzululwazi kunye novavanyo, olufuna ukuchaneka phantse okungqongqo, iqonga lokuchaneka loxinzelelo olusisigxina lomoya odadayo oluxhaswa yisiseko segranite sidlala indima ephambili engenakuphinda ibuyiselwe, ukukhuthaza uphuhliso lwamashishini ahlukeneyo ngokubhekiselele ekuchanekeni okuphezulu.
