Kev qhia luv luv ntawm cov ntaub ntawv tshiab
Apr 22, 2021
Nrog txoj kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis, tib neeg tau tsim cov ntaub ntawv tshiab raws li cov ntaub ntawv ib txwm muaj thiab cov kev tshawb fawb ntawm cov kev tshawb fawb niaj hnub thiab thev naus laus zis. Cov ntaub ntawv tshiab tau muab faib ua plaub pawg: cov ntaub ntawv siv hlau, cov khoom siv uas tsis yog inorganic (xws li ceramics, gallium arsenide semiconductors, thiab lwm yam), cov ntaub ntawv organic organic, thiab cov khoom siv hluav taws xob zoo ntxiv. Raws li cov khoom ntiag tug, nws tau muab faib ua cov cuab yeej tsim khoom thiab cov khoom ua haujlwm. Cov khoom siv cov khoom siv tsuas yog siv cov tshuab ua lub cev thiab lub cev thiab tshuaj ntawm cov khoom kom tau raws li kev ua haujlwm ntawm kev ua kom lub siab, lub siab tawv, lub siab tawv, qhov kub tsis kam, hnav tsis kam, tiv taus corrosion, thiab hluav taws xob tsis kam; cov khoom ua haujlwm tsuas yog siv cov khoom siv hluav taws xob thiab sib nqus ntawm cov khoom. , Suab, lub teeb, kub thiab lwm yam teebmeem kom ua tiav qee qhov haujlwm, xws li cov khoom siv hluav taws xob, cov khoom siv sib nqus, cov khoom siv duab, cov khoom ua kom sov, cov khoom siv ntxiag, thiab cov ntaub ntawv nuclear rau cov foob pob thiab foob pob. Cov ntaub ntawv tshiab ua lub luag haujlwm tseem ceeb hauv kev tsim kho kev tiv thaiv teb chaws. Piv txwv li, qhov kev vam meej ua tiav ntawm ultrapure silicon thiab gallium arsenide ua rau yug ntawm qhov loj thiab loj heev ntawm kev sib koom ua ke, uas ua rau muaj kev suav nrawm nrawm los ntawm pua pua txhiab txoj haujlwm ib ob mus txog ntau dua kaum lab nyiaj daus las hauv ib ob; Nce 100 ° C tuaj yeem nce ntau zog mus txog 24%; cov ntaub ntawv sib nqus tuaj yeem nqus cov hluav taws xob tsis zoo lossis txo cov hluav taws xob infrared tawg ntawm riam phom thiab khoom siv, ua rau nws nyuaj rau kev paub cov yeeb ncuab los tshawb nrhiav, thiab lwm yam.
Ib qho ntawm cov lus qhia tseem ceeb ntawm kev nthuav dav science thiab thev naus laus zis hauv 21st caug xyoo yog kev tsim kho thiab siv cov ntawv tshiab. Kev tshawb fawb ntawm cov ntaub ntawv tshiab yog ua ntej ntawm tib neeg rau ntawm kev nkag siab tob thiab kev thov cov khoom muaj zog.
