1, qhov tsim ntawm cov thwj cim hlau yuav tsum ua raws li cov khoom siv thiab kev ua haujlwm, thiab tuaj yeem pab pawg kho thiab kho.
2. Kev tsim cov hlau stampings yuav tsum yog qhov zoo rau kev txhim kho cov khoom siv hlau, txo cov ntau yam thiab kev qhia ntawm cov ntaub ntawv, thiab txo cov khoom siv. Tshaj li tau, cov ntaub ntawv pheej yig yog siv los ua qoob-dawb thiab tsawg li tsawg tau.
3, qhov tsim ntawm cov hlau nplaum yuav tsum yooj yim rau hauv cov qauv, tsim nyog, kom yooj yim rau simplification ntawm puab cov qauv, simplify cov xov tooj ntawm cov txheej txheem, uas yog, siv qhov tsawg tshaj, qhov nyuaj stamping txheej txheem kom tiav tag nrho ib feem ntawm cov kev ua haujlwm, kev txo cov kev siv lwm txoj kev ua, thiab yog qhov ua rau lub lag luam thim khoom ua haujlwm pabcuam cov koomhaum ntawm kev siv cuabyeej thiab kev siv khoom kom muaj zog kom muaj peev xwm ua tau haujlwm ntau dua.
4, qhov tsim ntawm cov thwj rau hlau, hauv qhov qub siv los xyuas kom meej tias tej yam kev mob, kom deb li deb tau los ua kom qhov tseeb qhov tseeb thiab qhov roughness qib yuav tsum qis qis dua, thiab yog qhov khoom sib yeem, txo cov khib nyiab, kom cov khoom zoo thiab kev ruaj ntseg.
5, tsim cov khoom ntawm cov hlau, yuav tsum ua kom siv cov cuab yeej tam sim no, cov khoom lag luam thiab cov txheej txheem kom ntau li ntau tau rau nws cov kev ua, thiab yog ib qho zoo rau kev txuas ntxiv rau txoj haujlwm ntawm kev tuag.
