Munguva refu yapfuura, takatora matafura eshanduko yekunze kune imwe yeChinese, asi panguva yekushandiswa, nekuda kwekuumbwa kwekemikari yezvinhu, tekinoroji yekugadzira, saizi yejometri yemuenzaniso uye zvimwe zvinhu pamwe nekururama kwezviridzwa zvekuyeresa zvakasiyana-siyana. nyika, kuomarara uye simba kutendeuka hukama kumisa hwaro uye data processing zvinoreva zvakasiyana, takaona kuti pane misiyano mikuru pakati pemhando dzakasiyana dzekutendeuka.Pamusoro pezvo, hapana chiyero chakabatana, nyika dzakasiyana dzinoshandisa tafura yekutendeuka yakasiyana, zvichiunza nyonganiso mukuoma uye simba rekushandura hunhu.
Kubva 1965, China Metrology Scientific Research uye mamwe mayuniti akagadzira Brinell, Rockwell, Vickers uye yepamusoro Rockwell kuomarara mabhenji uye simba kukosha pahwaro hukuru hwekuedzwa uye ongororo yekuongorora, kuongorora hukama hunoenderana pakati pekuoma kwakasiyana uye simba referrous. simbi, kuburikidza nekugadzirwa kwekuongorora.Yakagadzira yedu "black metal kuomarara uye simba rekushandura tafura" yakakodzera 9 simbi dzakateedzana uye zvisinei negiredhi resimbi.Mubasa rekuongorora, zvikamu zvinopfuura zana zvakatora chikamu, zviyero zvinopfuura zviuru zvitatu zvakagadziriswa, uye data inodarika zviuru makumi matatu yakayerwa.
Iyo data yekusimbisa yakagoverwa zvakaenzana pamativi ese eiyo shanduko curve, uye mhedzisiro yacho inoenderana nekugoverwa kwakajairika, ndiko kuti, aya matafura ekushandura anonyanya kuenderana neicho uye aripo.
Aya matafura ekushandura akafananidzwa pasi rese nematafura eshanduko akafanana enyika dze10, uye hunhu hwekutendeuka hwenyika yedu hunenge hweavhareji yekutendeuka kwenyika dzakasiyana siyana.
