Dab tsi yogHolmium oxidesiv rau?
Holmium oxideYog ib qho ntawm cov xim siv rau sau cov lus qhia zirconia thiab iav, ua ib qho kev ntsuas hluav taws xob, phosphor tshwj xeeb, muab cov xim laser, muab xim liab lossis xim liab. Nws yog siv rau hauv kev ua tshwj xeeb tsom iav. Iav muaj Holmium oxide cov kev daws teeb meem muaj cov txheej txheem kho kho kho kho qhov muag rov qab hauv qhov pom ntau. Raws li feem ntau lwm cov neeg oxides ntawm cov av tsis tshua muaj, oxium oxide yog siv los ua cov khoom siv tshwj xeeb, phosphor thiab cov khoom laser. Holmium laser ua haujlwm ntawm wavelength ntawm 2.08 micrometres, txawm nyob rau hauv pulsed lossis kev cai tas mus li. Lub laser no yog qhov muag tau nyab xeeb thiab siv nyob rau hauv cov tshuaj, lub hau, cua ntsuas thiab saib xyuas huab cua. Holmium tuaj yeem nqus cov fission-bred neutrons, nws tseem siv nyob rau hauv nuclear reactors los khaws cov tshuaj tiv thaiv atomic los ntawm kev tswj hwm.
