Isampula 583 zegolide

Kohlulwe mali ekubhekiselelwe kwisiqulatho legolide ngaphakathi ingxubevange, nto leyo yenziwa intwana ubucwebe. Ngendlela esulungekileyo kuthiwe sisinyithi elinqabileyo ithambe kakhulu yaye ngenxa yoko akukho ezifanele ukwenziwa izacholo ukusetyenziswa rhoqo yonke imihla. Ukunika iyinceda kuyimfuneko ukwenza aluminium kunye nezinye ngesinyithi, phakathi kwawo ezininzi eziqhele ukusetyenziswa ubhedu, isiliva. Lidla igolide ukudala imibala eyahlukileyo (umz ezibomvu okanye ezimhlophe) kunye neempawu ze ezinye iintsimbi zongezwa. Isixa zegolide equlethwe aluminium ezinjalo, isampuli echongiweyo. Ngexesha amaxesha Soviet, aziwayo kakhulu 583 sample yegolide.

Kwaye phambi kokuba umxholo kwimveliso iyeyegolide ecikizekileyo omiselwe carats, bekucingelwa ukuba 100% elivumelana 24 eqatywe ngegolide, kwaye ubukho naziphi ubumdaka iye yehla inani carats ngokuxhomekeke kwisixa ukungcola longeziwe. Le nkqubo kusekho e-UK, i-US nakwamanye amazwe athile. In Russian Empire, yaye kamva ku-1927, eSoviet Union iisampulu metal anqabileyo babezimisele ngokusebenzisa inkqubo vana yesilayidi, apho ingxubevange yahlulwe ngokuqhelekileyo lezabelo 96, kodwa hayi kwi-24.

Kwandula yiSoviet Union kwaye kumazwe amaninzi baqalisa ukusebenzisa inkqubo echanekileyo kakhulu metric. Oku kubonisa umxholo inani iinxalenye esulungekileyo metal elixabisekileyo ingxubevange 1000 iindawo. Kungenxa yenani leeyunithi negolide isampula ibala ukuba ibekwe kwi kwiphetshana ubucwebe. Ngokwale nkqubo, oko ujika ukuba eqatywe-14 zegolide kwisampulu ingqamana 583 zegolide, 18 carats - 750 njalo njalo. Le ichaza indlela imvelaphi sele eziqhelekileyo kuthi "non-setyhula" iisampulu amaxabiso metric. Xa kuthelekiswa ezi nkqubo zimbini ajike definition ezimbini zegolide ngokupheleleyo ecocekileyo. Ngokusemthethweni 24 eqatywe ngegolide kufuneka athobele le eqatywe-1000 ngegolide, kodwa practice ukufumana igolide loo akunakwenzeka yaye, ke ngoko, amaxesha kuthiwa "olunyulu" igolide iimvavanyo 999 (nines emithathu), kwaye maxa wambi nkqu esulungekileyo zegolide 24 eqatywe umnxeba ehambelanayo isampula 990.

Zonke ezisetyenziswa xa kusenziwa aluminiyamu zegolide yabelwa kwisampula ahambelanayo. Ekuqaleni USSR baba 958, 750, 585, 583 and 375 iisampuli. Ngelo xesha linye isampuli 583 ngegolide kunayo yonke. Aluminiyamu yale isampuli unokuba umbala owahlukileyo ngokuxhomekeke kwisixa zesinyithi non-ayoni eziqulathwe kuzo. Umzekelo, ukuba ingxubevange iqulethe iindawo 58,3 zegolide, izahlulo 5.7 ubhedu kunye nezahlulo 36 zesilivere, inombala oluhlaza, ukuba abe nombala elipinki ukuba namalungu 23.4 yobhedu nesilivere iinxalenye 18.3, xa isiqulatho 33 , izahlulo 4 lobhedu 8.3 inxalenye yesilivere lifumana sele Tint bubomvu.

Kuba igolide emhlophe, nto leyo lisetyenziswa kwimeko ngokwenziwa diamond izihombiso, naye wasebenzisa 583 sample yegolide. Kwakugcwele iinxalenye 16 nobhedu, nesilivere iinxalenye 23,7-28,7, izahlulo 8.7 zinc, kunye nezahlulo 13-18 nickel okanye palladium. Kwixesha elizayo, kuwo onke amazwe awayesakuba yiSoviet Union 583 isampuli yegolide latshintshelwa 585, waza waqalisa ukuthandwa zegolide, eye-750. Kufuneka kuqatshelwe ukuba umbala igolide akusoloko enxulumene iintanda. Xa sampulu inye, mhlawumbi kuba obomvu yellow, emhlophe, eluhlaza brown okanye emnyama.

Le iintsilelo baqonda phambi kokuba imbono yemveli ukuxhomekeka yebala igolide iisampulu yayo wambumba ngexesha leSoviet, xa yoshishino ukuvelisa izinto igolide umbala omnye sample nganye: 750-I - yellow, 583rd - bomvu 375-I - pink. Kodwa ngoku, ngenxa imveliso izacholo wasebenzisa ezahlukeneyo ezihlangene, yaye ngenxa yoko ke umbala zegolide mveliso ngokupheleleyo kuxhomekeka kwisixa equlethwe kubo metal amanene, kwaye isampuli ezifanayo zombini abamhlophe nabamnyama.
