925 sirivha yokuenzanisira - Science uye upfumi

Silver - zvinyoronyoro simbi, riri nyore kuti pave zvivezwa chero kunzwisisa uye inosiyana. Chinowanzoonekwa hwakakanyiwa emhangura kuti akasimba kupfuura zvakanga. Sezvo makarekare, musanganiswa simbi idzi yakashandiswa kuita mari. Mharidzo panguva iyoyo yaiva maminitsi 500 (50 muzana sirivha, 50 - mhangura). Zvisinei, kuti asike zvimwe mari inokosha, Somuenzaniso, kushandisa sirivha, mharidzo 925, riri aikoshesa zvikuru. Kazhinji, munhu chiwanikwa akadaro vakatorwa kuti kusika aakatipa kuyeukwa mari uye zvishongo.

Mazuvano 925 sirivha mharidzo ine panguva yayo chiwanikwa 7.5 muzana mhangura. simbi Izvi akakodzera pakusika zhinji kwezvishongo - rin'i, chishongo, norwonzi, nezvikorekedzo, uye zvakawanda. Uyewo zvikuru dzakakurumbira zvigadzirwa izvi nokuti zvine akatemerwa mutengo uye anowanikwa vanhu vazhinji. Akazviisa muzhizha pamahombekombe haana varumbidzwa nokuti kazhinji vakarasika, zvisingagone kukundikana kufadza vanhu vane simbi michina. Zvisinei, haasi munhu wose anoziva zvokuita zvakawanikwa akadaro. Asi 925 sirivha yokuenzanisira kutengwa katatu zvinodhura pane dzose. Kazhinji kugadzirwa zvishongo akaiswa pavo anokosha uye Semi-anokosha akadai nebheriri. zvinogadzirwa zvakadai tarisa zvinoorora zvikuru, havana kubuda mufashoni. Izvi Chokwadi, rinoshanda kwete chete kune simbi, asi goridhe. Mirangariro vanomhanya dzomusango apo pane jewelers, nekuti sirivha (925) epurasitiki chaizvo. Varume nevakadzi vakawanda vanosarudza kuti nedzimwe simbi dzinokosha.

Science uye sirivha

Zvisinei, chiwanikwa ichi chinoshandiswa kwete chete kuti kusika gizmos yakanaka, sezvo richishandiswa sayenzi. Kunyanya kodzero sirivha yokuenzanisira 925 nokuda zvakanaka conductivity. Mukuwedzera, simbi inoshandiswa mapikicha, paaisika girazi, apo kuratidza nani sirivha zvinganaka aruminiyamu. Dzimwe nguva simbi iri rakashandiswa mvura disinfection.

sema kuita

Vamwe vanhu vave sema kuti sirivha. Naizvozvo, kushandisa midziyo yakadai zvisina inokurudzirwa. Pfeka nyaya nesimbi ichi kuvana vaduku ndiyo zvakare haana zviripo.

Mimwe sirivha. Sei Vakaverenga?

Pari zvino pane zviri arşive wemuTesitamende Russia anoti ari chikamu esirivheri 1,000 vezvikwata zviri chiwanikwa, chinova chikamu. Izvi zvinoreva kuti 925 esirivha paminiti kilogram yokuenzanisira panhamba 925 magiramu zvesirivha uye vamwe - imhangura. Kusvikira mukutanga ramakumi remakore paiva vangapiwa hurongwa. Kazhinji anogona kuonekwa pamusoro mari shoko "vangapiwa 2 mugove 10.5". The yose Hurongwa inovakwa parimwe 96 Spools - paundi. Kuwedzera 925, pane dzimwe, yakaderera. Somuenzaniso, 800, 830, 875, izvo zvikurukuru akashandisa kusika silverware uye nemidziyo. inivhesitimendi

Vanhu vakawanda vari kupedza mari yavo mari, nekuti mutengo mari mari pakakwirira ose gore. Zvisinei, izvozvo zvose zvinoenderana pamutengo nyika, iyo anosarudza kukosha zvinokosha simbi. chinhu chimwe nechimwe chiwanikwa ichi anofanira dzakarukwa zvakanaka kunyorwa mharidzo. Kazhinji kacho pasina rinokudza girazi kuona hazvina, asi zviri kuwanikwa, nokuti ndiwo sei unogona kusiyanisa pakati simbi anokosha kubva nyepera.
