Izinkinobho, ekuqaleni esetshenziselwa isixhumanisi sezingubo, noma kunjalo, ithuthukiswe kuze kube namuhla, izinkinobho ngaphezu komsebenzi wokuxhumanisa wangempela kakhulu, kodwa futhi yanwetshwa ekuhlobiseni nasekuhlobiseni umsebenzi.Ngokocwaningo, umlando wezinkinobho zaseShayina ungalandelelwa emuva okungenani eminyakeni eyi-1800 edlule.Izinto eziyinhloko zezinkinobho zakuqala ziyitshe, izinkuni, indwangu nokunye.Ngekhulu le-13, abantu basezwenikazi laseYurophu baqala ukusebenzisa izinkinobho.Ngemva kweNguquko yezimboni ekhulwini le-18, izinkinobho zensimbi zaqala ukuduma.
Ngakho-ke, zilinganiswa kanjani izinkinobho?Iyunithi yenkinobho ibizwa ngokuthi L, uhlamvu lokuqala lwe-ligne.
Iyini i-Ligne?
I-Ligne iyiyunithi yobude esuselwa egameni lesiFulentshi elisho umugqa.I-Ligne yaqala ukusetshenziswa abakhiqizi bezinkinobho baseJalimane ngekhulu lesi-9 ukuze banqume usayizi wezinkinobho, futhi ekugcineni yaba iyunithi evamile yokulinganisa izinkinobho ngekhulu le-18.
Ukuguqulwa kobukhulu
Abantu abangawazi usayizi wenkinobho L bangakwazi futhi ukuyiguqula ibe amayintshi noma amasentimitha.
1 L = 0.635 mm
1 mm = 1/25"
Isibonelo, uma ububanzi benkinobho bungu-18mm, ubukhulu benkinobho bungabalwa bungu-28L (18/0.635=28.34).
Okulandelayo yithebula lokuguqula usayizi ojwayelekile.
Ithiphu:
1, I-diameter yenkinobho: ubukhulu obukhulu obungaphandle benkinobho.
2, Ububanzi bebhande: Kala ububanzi obungaphakathi.
Nakuba uhlelo lokulinganisa lweinkinobhousayizi uzwakala uyinkimbinkimbi ekuqaleni, empeleni kulula kakhulu ukubala.VUMBAuziphuizinkinobho zokunikezela zobukhulu obuhlukahlukene kanye nezinto zokwakha, uma udinga, ungabonisana ngokuningiliziwe.
