Chii chisingawanzo-pasi?
Dzidziso dzakatadzisa
Kubva muZita, mumwe anogona kufungidzira kuti izvi "zvisingawanzo," asi maererano nemakore anofara (iyo chiyero chakasimbiswa pakugadzirwa kwegore) uye zvakanyanyisa kuputika kwevhu, ivo vanonyanya kuwanda kupfuura zvaitaurwa kana zinc.
Nekushandisa zvinobudirira zvinobudirira nyika, munhu anogona kutarisira kuti shanduko dzinoshamisa kuzvinhu zvakasikwa; Shanduko dzakadai sehunyanzvi hwekuvandudzwa kuburikidza nekushanda kukuru, kuvandudzwa kwekusimba kwezvivakwa uye zvakavandudza kugona kwesimba kwemashini emagetsi nemidziyo.
Nezve rare-yepasi oxides
Iyo rare-yepasi-yeLoides yeboka dzimwe nguva inongotaurwa nezvake nyika chete kana dzimwe nguva seimwe. Dzimwe simbi dzisingawanikwe dzakawedzera kuyamwirwa pasi pemagetsi, ceramics, girazi kugadzira, dhayi, lasers, terevhizheni uye zvimwe zvinhu zvemagetsi. Kukosha kwesimbi yepasi kushungurudzika kunonyanya kusimuka. Inofanira kufungwa, zvakare, kuti mazhinji epasi-ane zvinhu zvepasi-zvine zvigadzirwa zvekushandisa maindasitiri ndege ingangoita nzombe, kana kuti inowanikwa kubva mumhou.
Pamusoro peiyo yakawanda uye yakasimba maindasitiri ekushandisa kwepasi opartes, zvakadai mumatatu maindasitiri ekugadzira Zvimwe zvakakosha maindasitiri anoshanda neyemaindasitiriti (anoshandiswa seyakawedzerwa mu fe fe fe fe) Pamusoro pezvo, asi kwete kuderera, pane zvakadzama zvikumbiro zvekushandisa, sekushandiswa kweBiomicticed yeNyanparticated zvine nguva refu kune kurapwa kwegomarara, kana seyakagadzirwa svutugadzike yekudzivirira kweganda.
About Rare-Pasi Compounds
Kuchena kwakanyanya zvisingaite Pakupedzisira idzo makomisheni anogadzira carbonate, hydroxide, phosphate uye fluorides.
Vanenge makumi mana muzana evashoma vekugadzirwa kwepasi rinoshandiswa mune simbi fomu-yekugadzira magneti, elede elederodes, uye alloys. Simbi dzinogadzirwa kubva pane dziri pamusoro pamakomputa nekukwirisa kwakasarudzika masimba ehukama uye kukwirira kwakanyanya kushayiwa kwesimbi, semuenzaniso, calcium kana lanthanum.
Zvisingawanzo zvepanyika zvinonyanya kushandiswa mune zvinotevera:
●MAgnets (anosvika zana emagineti pamotokari nyowani)
● CatalyStts (mota inobuda uye petroleum cracking)
● Girazi Polising Pounds yeTerevhizheni Screens uye Glass Data Yekuchengetedza Disk
● Akashandisirwa mabhatiri (kunyanya kune mahybrid mota)
● Photonics (luminescence, fluorescence uye midziyo yechiedza)
● Magneti nemaForonics anotarisirwa kukura zvakanyanya makore mashoma anotevera
Urbanmines inopa kabhuku yakakwana yekuchena yakanyanya uye Ultra yakakwirira yekuchenesa makomputa. Kukosha kweKashoma Pasi Pasi Kunokura Zvakasimba Mune Dzakawanda Key Technologies uye hadzisingagadzirisike mune dzakawanda zvigadzirwa uye maitiro ekugadzira. Isu tinopa zvinhu zvisingawanzoitika mumakiredhi akasiyana zvichienderana nezvinodiwa zveumwe neumwe, izvo zvinoshanda semidziyo yakakoshesa mune dzakasiyana-siyana maindasitiri.
Chii chisingawanzo-zvepasi zvinowanzoshandiswa mukati?
Kushandiswa kwekutanga kwemaindasitiri kwevanhu vepanyika kwaive kweiyo dombo muvengo. Panguva iyoyo, tekinoroji yekuparadzaniswa uye kunatsiridzwa yakanga isina kuvandudzwa, saka musanganiswa wepasi rose risingawanzoitika pasi uye zvinhu zvemunyu kana zvisina kujairika zvisizvo (alloy) akashandiswa.
Kubva kuma1960, kuparadzaniswa uye kunatsiridzwa kwakaitika uye zvinhu zviri mukati meumwe neumwe pasi rakavonekwa. Zvekununwisa kwavo, ivo vakatanga kunyorwa seCathode-ray tube phosphors yeiyo mavara e-mavara uye pane yakakwira Refractive kamera lens. Ivo vakaenderera mberi nekupa mukudzora saizi uye uremu hwemakomputa, makamera edhijitari, midziyo yedhiji uye zvimwe kuburikidza nekushandisa kwavo mashandisirwo emagineti ekusingaperi uye anogadziriswazve mabhatiri.
Mumakore achangopfuura, ivo vaitarisisa sechinhu chakabikwa cheHydrogen-chinja mari uye magineti egineststronts.
