Yintoni na iisampuli zesilivere? Iinkcukacha iisampuli zesilivere

Ezinye kumangaliswa yokuba ijuwelari lunqabe ezenziwa izinto ecocekileyo. Oku kungenxa iipropati ngokwabo kwaye amatye anqabileyo, nokuba yigolide engcwengekileyo okanye isiliva kunqabile imveliso. Iimveliso Clean baqhele ukuba babe umbala owahlukileyo kwaye neempawu ezahlukeneyo.

Ziziphi iisampulu yisilivere ukuba avela ngaphi na?

Silver, njengezinye amatye anqabileyo, izinto alloying nga ingangxengeka phantse ad infinitum. Ngokuqinisekileyo, oko ngokonakalisa ixabiso layo. Ngokweliso ukwahlula umgangatho yesilivere "yaze yangxenga ifuthe lomanyano" asinto ilula kakhulu.

Ukuze ukwahlula thile fake ukusuka kwimveliso yokwenene, kunye nenkqubo isampuli iye yaziswa. Isebenza ukususela 1927 kwaye nangoku efanelekileyo namhlanje kummandla lamazwe Russia kunye ico. Ngokutsho metric, umgangatho imveliso ixhomekeke impahla ecocekileyo elixabisekileyo capacity ngo-1000 grams. Oko kukuthi, ukuba isampuli imveliso 925, oko kuthetha ukuba omnye obunzima buyikhilogram enye ingxubevange loo zesilivere 925 grams 75 alloying zesinyithi.

Xa phambili, besithi ephezulu isilivere kulingwa - 960. Kodwa kutheni ngo 1000? Silver ngokwayo izinto ithambe kakhulu, kwaye ngoko ke kubalulekile ukuba "omeleze" nickel, ikopolo, izinc okanye aluminium. I-copper ezininzi ezisetyenziswayo ngokuqhelekileyo. Esebenzisana kunye nesinyithi ezinjalo, oko uzuza amandla. Kubalulekile ukuqaphela ukuba ama-80% -s 'aluminium non-ezixabiseke ngayo ngokusemthethweni eRashiya.

isiliva technical

Silver ngaphandle isampula, ipesenti umthamo ngezantsi 80, ekuthiwa metal zobugcisa. Manufacturing izinto ezinjalo izinto lisusiwe. Kodwa intetho malunga umgangatho walo ihlwempu ayikho kakhulu echanekileyo. Isibakala sokuba kuye kwenyuka amandla. Metal ngenxa yayo emzimbeni - ngumnqweno ezivelisa iinxalenye ukuba kunomathotholo eziphathekayo. Silver isetyenziswa lokuyila relay.

La malungelo ngayo eAmsterdam ngenxa yokukhanya kunye conductivity eliphezulu zombane.

Kuthiwa kule isilivere ingaveliselwa nezacholo ukuba wena akunguye isampula esisiseko. kodwa ke kufuneka kuqatshelwe ukuba wentsimbi akujongwa anqabileyo.

Forms of iisampuli zesilivere

Iinkcukacha lwemizekelo zesilivere (ezo iisampulu zesilivere) ukuqhubeka.

Le metal, egqalwa anqabileyo, ephawulwe ngolu hlobo lulandelayo:

• 800 - Ngesandla;
• 830 - isetyenziswe ukuvelisa izinto zokubhala kunye nezinto angabizi;
• 875 - basekhaya;
• 925 - izacholo, bande;
• 960 - kwavavanywa isampula;
• 999 - isiliva obalaseleyo.

Iinkcukacha iisampuli zesilivere

Ziziphi iisampulu zesilivere, siye safumanisa. Ngoku, cinga injongo yabo.

1. Yesilivere 800 m "ibala" kuthetha ukuba akukho nyulu ngaphantsi kwe-80%. Ngayo ixesha elide kakhulu kwaye iipropati eyahlulayo ekumgangatho ophezulu. Kodwa kukho thabatha - into oxidized ngokukhawuleza kwi evulekileyo. Kungenxa yesilivere kusetyenziselwa ukwenza izacholo. Esinye isizathu - umntu umthunzi ezikhethekileyo mthubi ukuya ngobhedu, ngoko ukwahlula ngokulula ukusuka kwiintlobo ubucwebe.
2. Kucacile ukuba ukongeza ekhulwini ezintathu ingxubevange zesilivere, kungekhona kakhulu kuyayitshintsha iimpawu ebonakalayo imveliso ogqityiweyo. Ngoko ke, injongo ephambili isampuli - neefolokhwe yokuvelisa, neenkamba neemela.
3. Xa uluhlu isampulu zesilivere - zeziphi na iintlobo - i-875-I isetyenziswa izacholo. UMhombiso kwesicwangciso kufuneka ngokuba "udidi economy". Inyaniso ukuba ixabiso kwiimveliso kwaye nangenxa aphantsi ndinamandla kakhulu, xa kuthelekiswa ne-isilivere esulungekileyo, kunzima ukwenza afakwe umsebenzi.
4. 925-I isampuli Yisilivere - eqhelekileyo kakhulu kwishishini izacholo. Okokuqala, umthamo ophantsi ezinye iintsimbi undomelezayo luphawu entle zona yesilivere. A efanayo ngobulungisa ezithambileyo kwenza kube lula ukuvelisa lwemenu emangalisa. With konke oku, kukho isilivere omkhulu kugcina imilo yayo.
5. 960-I isampuli ekuso ukuba izacholo. iipropati Visual and physical uyafana we-925. Nangona kunjalo, akukho mngcipheko mkhulu umonakalo. Uncedo kuphela - phantse akuthethi oxidize kwaye, ngenxa yoko, ayikho mnyama.

Iisampulu zesilivere, yintoni na yaye yintoni ukusetyenziswa? Umbuzo kakhulu ezithile. Wonke umntu kufuneka ngokuzimeleyo isigqibo oko iimpawu kufuneka imveliso ukuba ukulungele ukuyithenga.

isiliva oncomekayo

Ngoku uyazi iintlobo zesilivere. Yintoni na isampuli yesilivere nendlela isampuli obekwe kwi imveliso ogqityiweyo - Ayifumaneki. Okulandelayo, makhe sithethe metal ecocekileyo.

Silver, ephawulwe sampula 999th, uthambile. It is a metal enyulu, into leyo isetyenziselwa ukwenza izacholo. yayo lula kakhulu ukuba ukugoba okanye ukwaphula. Ukuba wenza nezidanga zesilivere ocoliweyo, ukongeza, iya ngokukhawuleza kuphulukana imilo, kwaye nangoko itshintsha umbala wayo: intsimbi yiluciferase ngokukhawuleza kwaye lube buthuntu.

loqobo isetyenziselwa lokunyibilikisa of etshe okanye zemali nombuthi. Ngokwazo, ezi zinto azisetyenziselwa kubomi bemihla ngemihla, nto leyo enciphisa umonakalo kumphezulu.

Indlela ukujonga umgangatho wendlu zesilivere?

ubuchwepheshe bale mihla ukuvumela ukuba kwakhiwe izivatho ukwenzela ukuba nzima ukwahlula into yokwenene. Kodwa ukubuyela imveliso kwiintsuku ezili-14 iye yarhoxiswa ngenxa yokuba, esiza ekhaya kwaye wolinciphisa ezichulumancisa ngayo izinto ezintsha, sicebisa ukuba benze uvavanyo ezilula zokukunceda ukufumanisa nokwakheka ngayo.

Ke kaloku, ukuba uyazi ukuba yintoni na isampuli yesilivere. Kodwa indlela yokubona nobunyaniso mveliso?

1. Yokuqala enye uvavanyo kakhulu ngempumelelo - hlola umazibuthe. yesilivere Real aziyi umdla. Noko ke, asiyiyo metal kuphela abasoloko 'umtsalane' le umazibuthe. Ngoko ke kufanele kubekho uvavanyo olongezelelweyo.
2. Unako ukudlala kunye conductivity thermal. Silver ngokukhawuleza kuthatha phezu lobushushu kuma kulo. Vele ubeke - nangoko itshiswe ngesandla yaye ikhawuleza iphele phantsi ngamanzi abandayo.
3. Kungenjalo, sisalathisi zingasetyenziswa iodine. A nethontsi ayodini uza kushiya ibala emnyama. Kodwa khumbula, yaye oko ekucoceni ibala ayikho simple kangaka.

Asazi singacebisi yokugoba notching imveliso. Ukuba njengentsomi, ngoko kuya kuba akunakwenzeka ukuba babuye, ugcine imveliso ibhuqiwe - bamkhahlele phantsi esinkini imali.

Kaloku sonke siyazi ngale but is: yintoni na iisampuli zesilivere, ezithi zisetyenziswe. Ngoko ke, xa uthenga iimveliso baya kukwazi ukwenza ukhetho olufanelekileyo.
