Kwimveliso yanamhlanje, ukuchaneka akuyonjongo nje kuphela—yimfuneko. Nokuba uvelisa izinto zeenqwelo-moya, izixhobo zonyango, okanye iindawo zeemoto, ukuchaneka kokulinganisa kuchaphazela ngokuthe ngqo umgangatho wemveliso, ukhuseleko, kunye nokuthobela. Kulapho izixhobo zokulinganisa i-granite ziye zazimisela khona njengomgangatho weshishini wokulinganisa ngokuchanekileyo kunye nokusetyenziswa kwe-metrology.
Izixhobo zokulinganisa igranite, ingakumbi ipleyiti yomphezulu wegranite, zibonelela ngesiseko esizinzileyo nesihambelanayo ngokwemilinganiselo esenza ukuba uhlolo oluchanekileyo lube nokwenzeka. Ngokungafaniyo nentsimbi okanye isinyithi esityhidiweyo, igranite ibonisa uzinzo olukhethekileyo lobushushu, ukwanda okuncinci kobushushu, kunye nokumelana nokuguguleka okubalaseleyo. Ezi mpawu zenza igranite ibe yinto ekhethwayo kwiilebhu zemetrology kunye namasebe olawulo lomgangatho kwihlabathi liphela.
Esi sikhokelo senyathelo ngenyathelo siza kukubonisa indlela efanelekileyo yokusebenzisa izixhobo zokulinganisa i-granite ukuze uhlolwe ngokuchanekileyo. Ukususela ekusetweni kokuqala ukuya kumaxwebhu okugqibela, siza kugubungela yonke into ekufuneka uyazi ukuze ufumane imilinganiselo ethembekileyo nephindaphindwayo ehlangabezana nemigangatho yamazwe ngamazwe.
Ukulungiselela: Ukubeka Inqanaba Lokuchaneka
Ngaphambi kokuba kuqalwe naluphi na umlinganiselo, ukulungiselela ngokufanelekileyo kubalulekile. Ukukhawulezisa eli nqanaba kudla ngokukhokelela kwiimpazamo zokulinganisa ezinokuphepheka.
Iimeko zeNdalo
Into yokuqala ekufuneka uyiqwalasele yindawo olinganisa kuyo. Ngokwemigangatho ye-ISO 17025 kunye ne-ASME B89.3.7, ulawulo lobushushu lubaluleke kakhulu. Gcina ubushushu obuqhelekileyo obuyi-20°C (68°F) bunokunyamezela okungu-±1°C. Oku kuqinisekisa ukuba izixhobo zokulinganisa i-granite kunye nezinto zokusebenza zihlala zizinzile ngexesha lokulinganisa.
Ukutshintsha kobushushu kubangela ukwanda okanye ukucutheka kobushushu. Utshintsho lwe-1°C kwinxalenye yentsimbi eyi-100mm lubangela utshintsho olumalunga ne-0.0011mm—olwaneleyo ukubangela ukwaliwa kwizicelo ezichanekileyo. Qinisekisa ukuba indawo yakho yokulinganisa ayinazo ii-drews, ilanga elithe ngqo, kunye nemithombo yokungcangcazela efana noomatshini abakufutshane okanye ukuhamba ngeenyawo.
Ukuhlolwa kwezixhobo kunye nokuCocwa
Ngaphambi kokuba uqale naluphi na uhlolo:
- Hlola ngokubonakalayo zonke izixhobo zokulinganisa i-granite ukuze ubone iitships, imifantu, okanye umonakalo womphezulu
