Rau cov khoom precision, kev ua haujlwm nruj heev, cov txheej txheem ua haujlwm muaj cov cuab yeej hauv, cov cuab yeej tawm, thiab lwm yam.. Muaj cov kev cai tshwj xeeb rau qhov loj thiab qhov tseeb, xws li 1 hli ntxiv lossis rho tawm pes tsawg microns, thiab lwm yam. Yog tias qhov loj me tsis raug. ntau dhau nws yuav dhau los ua cov khoom seem, uas yog sib npaug rau qhov yuav tsum tau rov ua dua, siv sijhawm thiab siv zog, thiab qee zaum txawm ua rau tag nrho cov khoom siv seem, uas ua rau tus nqi nce ntxiv, thiab tib lub sijhawm, qhov tseem ceeb yog qhov tseeb. tsis muaj. Yog li precision qhov chaw ua tiav thaum kawg ua raws li cov qauv thiab cov cai? Hauv qab no kuv yuav muab ib qho kev qhia rau koj:
Rau qhov kev ua tiav qhov kev ua tiav yog qhov yuav tsum tau ua, xws li ntau npaum li cas lub cylindrical txoj kab uas hla, muaj cov kev cai nruj, qhov zoo thiab qhov tsis zoo yuam kev nyob rau hauv cov kev cai yuav tsum tau tsim nyog qhov chaw, txwv tsis pub lawv yog unqualified qhov chaw; qhov ntev, qhov dav thiab qhov siab kuj tseem muaj cov kev cai nruj nruj, qhov zoo thiab qhov tsis zoo qhov yuam kev kuj tau teev tseg, xws li lub tog raj kheej embedded (kiv qhov yooj yim tshaj plaws piv txwv), yog tias txoj kab uas hla loj dhau, ntau dua qhov yuam kev tau tso cai, nws yuav tshwm sim los ntawm, ntxig tsis rau hauv qhov teeb meem, yog tias qhov tseeb txoj kab uas hla yog me me dhau, ntau tshaj qhov qis qis ntawm qhov tsis zoo ntawm qhov kev ua yuam kev tau tso cai, nws yuav ua rau ntxig dhau xoob, tsis muaj teeb meem tshwm sim. Cov no yog cov khoom tsis tsim nyog, lossis qhov ntev cylindrical ntev dhau los lossis luv dhau, dhau ntawm qhov kev ua yuam kev, yog cov khoom tsis tsim nyog, yuav tsum tau muab pov tseg, lossis rov ua dua, uas yuav ua rau muaj kev nce nqi ntxiv.
Precision qhov yuav tsum tau ua nyob rau hauv qhov tseeb qhov teeb meem loj loj, yuav tsum nruj raws li lwm yam ntxiv rau kev ua, kev ua tawm ntawm qhov loj me yuav yeej tsis zoo ib yam li qhov theoretical loj ntawm cov duab kos, tab sis, ntev li ntev tau. Qhov loj me nyob rau hauv qhov kev ua yuam kev kam rau ua yog qhov tsim nyog, yog li qhov yuav tsum tau ua ntawm precision qhov chaw ua haujlwm yog nyob rau hauv nruj raws li qhov theoretical loj rau kev ua.
Qhov thib ob yog qhov ua tau zoo tshaj plaws ntawm cov khoom siv thiab cov khoom siv kuaj, cov cuab yeej ua haujlwm siab heev ua rau kev ua cov khoom ua tau yooj yim dua, siab dua precision, zoo dua. Cov cuab yeej kuaj xyuas tuaj yeem kuaj xyuas qhov tsis ua raws li qhov yuav tsum tau ua, kom tag nrho cov khoom xa tuaj rau cov neeg siv khoom tiag tiag ua tau raws li qhov yuav tsum tau ua.
