Munguva yakapfuura, isu tinotora matafura ekunze ekunze kuChinese, asi panguva yekunyora kwemakemikari, kuomarara kwesimba. Mukuwedzera, hapana chakabatana chakaenzana, nyika dzakasiyana shandisa tafura yakasarudzika, ichiunza nyonganiso mukuomarara uye kushandurwa kwesimba.
Kubva 1965, China Metrology Scienicific Kutsvaga uye mamwe mayuniti akagadzwa Brinell Yakagadziridzwa yedu "dema simbi yakaoma uye kushandura tafura" yakakodzera kune 9 Steel Simbi uye zvisinei neGiredhi Giredhi. Mubasa rekusimbisa, vanopfuura zana zvikamu zvakatora chikamu, huwandu hwakawanda hwemasampuli zviuru zvitatu zvakagadziriswa, uye data rinopfuura makumi matatu dzakayerwa.
Iyo data yekusimbisa inogoverwa kumativi ese maviri ekutendeuka curve, uye mhedzisiro yacho inoenderana nekuparadzirwa, ndiko kuti, aya matafura ekushandura ari mumutsara ane chokwadi uye aripo.
Iyi matafura ekushandura akafananidzwa nenzvimbo dzemukati dzenzvimbo dzenyika dzenyika dzegumi, uye tsika dzekutendeuka dzenyika yedu dzinosangana neyekuchinja kwezvinhu zvakasiyana siyana.
