Dhinaca cabbirka saxda ah, madal sax ah oo granite ah oo leh xasillooni aad u wanaagsan, adkeysi sare iyo iska caabin wanaagsan oo xirasho, ayaa noqotay taageerada aasaaska ugu habboon ee shaqooyin badan oo cabbir sax ah oo sare leh. Si kastaba ha ahaatee, isbeddellada heerkulka ee arrimaha deegaanka, sida "dilaha saxda ah" ee ku qarsoon mugdiga, waxay leeyihiin saameyn aan la dayaci karin oo ku saabsan saxnaanta cabbirka ee madal sax ah oo granite ah. Waa muhiimad weyn in si qoto dheer loo baaro heerka saameynta si loo hubiyo saxnaanta iyo isku halaynta shaqada cabbirka.
In kasta oo granite-ku loo yaqaan xasilloonidiisa, haddana ma difaaco isbeddellada heerkulka. Qaybaha ugu muhiimsan waa quartz, feldspar iyo macdano kale, kuwaas oo soo saari doona ifafaale ballaarinta kulaylka iyo isku-soo-ururinta heerkul kala duwan. Marka heerkulka deegaanku kor u kaco, goobta saxda ah ee granite-ka waa la kululeeyaa oo la ballaariyaa, cabbirka goobtana si yar ayuu isu beddeli doonaa. Marka heerkulku hoos u dhaco, wuxuu dib ugu soo laaban doonaa xaaladdiisii asalka ahayd. Isbeddellada cabbirka ee u muuqda kuwo yar ayaa lagu weynayn karaa arrimo muhiim ah oo saameeya natiijooyinka cabbirka xaaladaha cabbirka saxda ah.
Tusaale ahaan, marka la eego qalabka cabbiraadda isku-dhafka ah ee isku-dhafka ah ee isku-dhafka ah, hawsha cabbirka saxnaanta sare leh, shuruudaha saxnaanta cabbiraadda badanaa waxay gaaraan heerka micron ama xitaa ka sarreeya. Waxaa la qiyaasayaa in heerkulka caadiga ah ee 20℃, xuduudaha cabbirrada kala duwan ee madalku ay ku jiraan xaalad ku habboon, xog sax ahna waxaa lagu heli karaa iyadoo la cabbirayo shaqada. Marka heerkulka deegaanku isbeddelo, xaaladdu aad bay u kala duwan tahay. Ka dib tiro badan oo tirakoobka xogta tijaabada ah iyo falanqaynta aragtiyeed, xaaladaha caadiga ah, isbeddelka heerkulka deegaanka ee 1℃, ballaarinta toosan ama isku-soo-ururinta madal sax ah ee granite waa qiyaastii 5-7 ×10⁻⁶/℃. Taas macnaheedu waa in madal granite ah oo leh dherer dhinac ah oo 1 mitir ah, dhererka dhinacu wuu isbeddeli karaa 5-7 microns haddii heerkulku isbeddelo 1 ° C. Cabbiraadaha saxda ah, isbeddelka cabbirka noocaas ah ayaa ku filan inuu keeno khaladaadka cabbirka ee ka baxsan xadka la aqbali karo.
Shaqada cabbirka ee looga baahan yahay heerarka saxnaanta kala duwan, heerka saamaynta isbeddelka heerkulka ayaa sidoo kale ka duwan. Cabbiraadda saxda ah ee caadiga ah, sida cabbirka cabbirka qaybaha farsamada, haddii qaladka cabbirka la oggol yahay uu ku jiro ±20 microns, sida waafaqsan xisaabinta isku-dhafka ballaarinta ee kor ku xusan, isbeddelka heerkulka waa in lagu xakameeyaa inta u dhaxaysa ± 3-4 ℃, si loo xakameeyo khaladka cabbirka ee ka dhasha isbeddelka cabbirka goobta heer la aqbali karo. Meelaha leh shuruudaha saxnaanta sare, sida cabbirka habka lithography ee wax soo saarka jajabka semiconductor, qaladka waxaa loo oggol yahay gudaha ± 1 micron, isbeddelka heerkulkana waa in si adag loo xakameeyo gudaha ± 0.1-0.2 ° C. Marka isbeddelka heerkulku ka bato heerkan, ballaarinta kulaylka iyo isku-soo-ururinta goobta granite-ka waxay sababi kartaa leexasho natiijooyinka cabbirka, taas oo saameyn doonta wax-soo-saarka wax-soo-saarka jajabka.
Si wax looga qabto saameynta isbeddelka heerkulka deegaanka ee saxnaanta cabbiraadda ee madal saxnaanta granite-ka, tallaabooyin badan ayaa badanaa lagu qaataa shaqada dhabta ah. Tusaale ahaan, qalabka heerkulka joogtada ah ee saxda ah ee sare ayaa lagu rakibay jawiga cabbiraadda si loo xakameeyo isbeddelka heerkulka ee meel aad u yar; Magdhawga heerkulka waxaa lagu sameeyaa xogta cabbirka, natiijooyinka cabbiraaddana waxaa lagu saxaa algorithm-ka software-ka iyadoo la raacayo isku-dhafka ballaarinta kulaylka ee madal iyo isbeddellada heerkulka waqtiga-dhabta ah. Si kastaba ha ahaatee, iyadoon loo eegin tallaabooyinka la qaadayo, fahamka saxda ah ee saameynta isbeddelka heerkulka deegaanka ee saxnaanta cabbirka ee madal saxnaanta granite-ka waa aasaaska hubinta shaqada cabbirka saxda ah oo la isku halleyn karo.
