Cov phaj tshuaj xyuas granite yog ib qho cuab yeej tseem ceeb hauv kev kho cov khoom siv kho qhov muag, muab qhov chaw ruaj khov thiab meej rau kev ntsuas thiab kev kho qhov muag. Cov yam ntxwv ntawm granite ua rau nws yog cov khoom siv zoo tshaj plaws rau cov phaj no, vim nws ntom, tawv, thiab tiv taus kev nthuav dav thermal. Qhov kev ruaj khov no yog qhov tseem ceeb thaum kho cov cuab yeej kho qhov muag, vim tias txawm tias qhov kev hloov pauv me me tuaj yeem ua rau muaj qhov yuam kev loj hauv kev ua haujlwm.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv lub phaj tshuaj xyuas granite yog nws qhov tiaj tiaj. Cov phaj granite zoo yog tsim los ua kom tiav qhov kev kam rau siab zoo heev, feem ntau yog hauv microns. Qib kev raug no yog qhov tseem ceeb rau kev kho qhov muag khoom siv, vim nws ua kom ntseeg tau tias cov cuab yeej tau teeb tsa kom raug thiab kev ntsuas yog qhov tseeb. Thaum cov khoom siv kho qhov muag, xws li lub lens thiab daim iav, raug kho rau ntawm qhov chaw tiaj tiaj, cov txiaj ntsig tau ntseeg tau ntau dua, yog li txhim kho kev ua haujlwm thiab lub neej ntawm cov khoom siv.
Tsis tas li ntawd xwb, cov phaj tshuaj xyuas granite tau tsim los kom kav ntev, thiab tuaj yeem tiv taus qhov nyuaj ntawm qhov chaw calibration uas tibneeg hu tauj coob. Tsis zoo li lwm cov ntaub ntawv uas yuav warp lossis lwj raws sijhawm, granite tswj nws qhov kev ncaj ncees, ua kom muaj kev ua haujlwm sib xws dhau xyoo ntawm kev siv. Qhov kev ruaj khov no txhais tau tias cov nqi kho qis dua thiab hloov pauv tsawg dua, ua rau cov phaj granite yog qhov kev daws teeb meem pheej yig rau cov chaw kuaj thiab cov chaw tsim khoom.
Tsis tas li ntawd xwb, cov phaj tshuaj xyuas granite tuaj yeem sib xyaw ua ke nrog ntau yam cuab yeej thiab khoom siv calibration. Lawv tuaj yeem siv nrog cov khoom sib piv optical, laser interferometers, thiab lwm yam khoom siv ntsuas precision los txhim kho cov txheej txheem calibration tag nrho. Kev ruaj khov ntawm granite ua ke nrog cov thev naus laus zis siab heev ntawm cov cuab yeej ntsuas optical tuaj yeem ua rau cov txheej txheem calibration yooj yim dua thiab thaum kawg ua tiav cov khoom siv optical zoo dua.
Xaus lus, cov phaj tshuaj xyuas granite ua lub luag haujlwm tseem ceeb hauv kev kho cov khoom siv kho qhov muag. Lawv qhov tiaj tiaj, ruaj khov, thiab sib xws nrog ntau yam cuab yeej ntsuas ua rau lawv yog ib feem tseem ceeb ntawm kev ua kom raug thiab kev ntseeg siab ntawm cov cuab yeej kho qhov muag.
