Njengoko amashishini eqhubeka etyhalela phambili ekuchanekeni kwesikali seathom kunye nokunyamezelana kwe-sub-micron, ukulinganiselwa kwezinto zemveli kuya kubonakala ngakumbi. Izixhobo zokulinganisa zeseramikhi, ezineempawu zazo ezibalaseleyo zemetrological, azikho nje ukhetho lokusetyenziswa ngokuchanekileyo okuphezulu—ziya kuba yimfuneko.
Kwimibutho ezinikele ekugcineni ukugqwesa kokulinganisa nokuxhasa ukuphuculwa okuqhubekayo kwimveliso echanekileyo, izixhobo zokulinganisa iseramikhi zimele utyalo-mali olucwangcisiweyo kwiziseko zokulinganisa. Umbuzo awukokuba izixhobo zeseramikhi ziya kuba ngumgangatho we-metrology echanekileyo kakhulu—umbuzo kukuba imibutho iya kutshintsha ngokukhawuleza kangakanani ukuze iqonde iingenelo zokhuphiswano ezibonelela ngazo.
Apha e-ZHHIMG, sigxile ekunikezeni izixhobo zokulinganisa zeseramikhi ezenziwe ngokwemigangatho echanekileyo kakhulu. Iibhloko zethu zeseramikhi ezithe tye, izikwere, kunye neegeyiji zenziwe kusetyenziswa izixhobo eziphambili kunye neenkqubo zokulungisa ngokuchanekileyo ukuze zinikezele ukusebenza okugqwesileyo kwizicelo zemetrology ezifuna kakhulu.
