Ngokwemininingwane, izinqamuli zezinzipho zaqala ukuduma e-United States naseYurophu, kodwa ngeminyaka yawo-1930, u-American Voss Foucault waba ngowokuqala ukufaka isicelo selungelo lobunikazi.Kusukela lapho, izinqamuli zezinzipho ziye zasabalala emhlabeni wonke.
Namuhla, lapho silungisa izinzipho zethu, sikhipha izinto zokugunda izinzipho.Nokho, izinto zokugunda izinzipho zasungulwa ekhulwini lama-20.Ngakho-ke, abantu basendulo babezilungisa kanjani izipikili kuyilapho zingekho izinto zokugunda izinzipho?Namuhla, aUmhlinzeki we-YaQin diamond drillizokwethula ukuthi abantu bakudala babezilungisa kanjani izinzipho.
Njengoba isisho sithi: Abantu bakhulisa izinwele ngokukhululeka nezinzipho zikhula ngokukhululeka.Eqinisweni, ubude bezinzipho buhlobene nobudala.Ngokwemininingwane, izinzipho zezingane zikhula cishe ngo-0.7 mm ngesonto.Njengoba bekhula, izinga lokukhula kwabo liyakhula.Ngemuva kwabantu abadala, izipikili zikhula ngesilinganiso sika-1 kuya ku-1.4 mm ngesonto, kodwa abantu abaningi bakhulisa izinzipho zabo ngemva kweminyaka engu-30. Ijubane lizohamba kancane.
Ngaphezu kwalokho, izinzipho zikhula ngokushesha ehlobo, zihamba kancane ebusika, zisheshe ekuseni, futhi ziphuze ebusuku.Ukuhlikihlwa njalo kuzosheshisa ukukhula kwezinzipho, ngakho-ke abantu abajwayele izinzipho ezingakwesokudla bakhula ngokushesha kunabangakwesokunxele.Izinga lokukhula kwezipikili ngalinye alifani ncamashi, ngokuvamile uma umunwe umude, uzipho lukhula ngokushesha.
Lezi zimfihlo ezincane empeleni ziseceleni kwethu, kodwa abantu abaningi abakazitholi.
Kulezi zinsuku uma abantu bekhula izinzipho bazosebenzisa izinqamuleli ukuzilungisa.Ngakho abantu basendulo babezilungisa kanjani izipikili kuyilapho zingekho izinto zokugunda izinzipho?Umhleli Wezinhlamvu Zansuku zonke ZaseShayina wabheka ulwazi futhi wathola impendulo.
Ngokwemibhalo egciniwe yokwaziswa, abantu basesenkathini yezimfene, njengezilwane zasendle zanamuhla, njengezimpisi, izingwe, nezingwe, ezigaya izinzipho okhunini, eziqwini zezihlahla nasematsheni.Kodwa-ke, ngemva kokuba abantu beqale ukusebenzisa amathuluzi, ngeNkathi Yamatshe, izinzipho zomuntu zazisikwa etsheni noma esihlabathini esimangelengele.
NgeNkathi Yethusi, abantu baqala ukupholisha izinzipho zabo emimese yethusi.Kamuva, isintu sasungula ifayela.Leli fayela liqhelelene nefayela lanamuhla, okungukuthi, kunezinhlayiya ezincane eziphuma phezu kwethusi, bese zihlikihlwa kulo.Kamuva, abantu bathola isikelo.
Njengamanje, isikelo esavunjululwa emathuneni asendulo Obukhosi Base-Western Han e-Luoyang sesineminyaka engaphezu kuka-2,100 XNUMX ikhona.Ngekhulu lesi-6 AD, izikele zaziswa eJapan zivela eShayina futhi zaqala ukwenziwa futhi zisetshenziswe ngobuningi ngesikhathi se-Edo.
Ngaphambi kokunquma izipikili, kungcono ukwelapha isikhumba esifile kanye nama-calluses ezinzipho ukuze wenze izipikili zikhule kangcono.II-YaQin diamond drillimbozwe ngamadayimane e-polycrystalline ahlala isikhathi eside, amelana nokungqubuzana futhi abekwe phezu kwenduku yensimbi engagqwali, engasusa ngokushesha nangempumelelo isikhumba esifile namanxeba ezinziphoni.Ingasetshenziswa futhi ekwelapheni i-cuticle.Ingaba nezinhlobo ezahlukene zomumo ukuze ivumelane nomsebenzi ofisayo.
