Ngokweemfuno zemethodi yomatshini kunye nokuchaneka kwendibano, ixabiso elifanelekileyo lebakala lokunyamezela liya kunyulwa ukulungiselela ukulinganisa.Ubungakanani ngaphandle kokubonakaliswa kokunyamezela kumzobo kuya kucaciswa ngokweemfuno ze-GB / t1804-2000 "ukunyamezela komgca kunye ne-angular dimensional ngaphandle kokubonisa ukunyamezela".

Ukumelwa komzobo ngokubanzi ngaphandle kokubonisa ukunyamezela

Phawula inombolo esemgangathweni kunye nekhowudi yebakala lokunyamezela kufuphi nebhloko yetayitile yomzobo okanye kwiimfuno zobugcisa kunye namaxwebhu obugcisa (njengemigangatho yoshishino).Umzekelo, xa ukhetha umgangatho ophakathi, ileyibhile ihamba ngolu hlobo lulandelayo:

GB/T 1804-m

Izakhiwo ezingaphawulwanga ngonyamezelo lwejometri kwimizobo ziya kumakishwa ngokwebakala le-GB / t1184-1996 "ukunyamezela kwejometri kunye nesikhundla ngaphandle kwamaxabiso okunyamezela komntu ngamnye".[1]
