Cov hlau ntshiab tau siv dav hauv hluav taws xob vim nws lub cev zoo heev, tshwj xeeb tshaj yog nws cov conductivity zoo. Hauv qab no yog cov ncauj lus kom ntxaws txog cov hluav taws xob conductivity ntawm cov hlau ntshiab:
1, Txheej txheem cej luam ntawm Conductivity ntawm Pure Hlau
Cov hlau ntshiab yog cov khoom siv hluav taws xob zoo heev. Nws cov conductivity feem ntau yog los ntawm tus naj npawb ntawm cov electrons dawb hauv nws. Nyob rau hauv cov hlau ntshiab, lub zog khi ntawm lub nucleus ntawm electrons sab nraum lub nucleus yog qhov tsis muaj zog, tso cai rau cov electrons txav mus rau hauv cov hlau lattice, yog li tsim txoj hauv kev zoo.
2, Cov yam ntxwv cuam tshuam rau kev ua haujlwm ntawm cov hlau ntshiab
Purity: Lub purity ntawm cov hlau ntshiab muaj qhov cuam tshuam ncaj qha rau nws cov conductivity. Qhov siab dua qhov purity, tsawg impurities thiab tsis xws luag nyob rau hauv cov hlau, thiab qhov tsawg dua hindrance ntawm lub zog ntawm electrons nyob rau hauv cov hlau yog, ua rau kom zoo conductivity.
Kub: Cov kev hloov pauv ntawm qhov kub thiab txias tuaj yeem cuam tshuam qhov conductivity ntawm cov hlau ntshiab. Raws li qhov kub thiab txias, cov atomic vibrations nyob rau hauv cov hlau ntshiab intensified, thiab cov cuam tshuam ntawm electrons nce, uas ua rau ib tug nce nyob rau hauv resistivity thiab ib tug txo nyob rau hauv conductivity.
Lattice qauv: Cov qauv lattice ntawm cov hlau ntshiab kuj muaj qee yam cuam tshuam rau nws cov conductivity. Cov qauv lattice sib txawv tuaj yeem ua rau txoj hauv kev sib txawv thiab cov txheej txheem tawg ntawm cov hluav taws xob hauv cov hlau, yog li cuam tshuam rau conductivity.
3, Kev Siv Cov Hlau Ntshiab hauv Cov Hluav Taws Xob
Electromagnets: Cov hlau ntshiab feem ntau yog siv los ua cov khoom tseem ceeb rau electromagnets vim nws cov conductivity zoo thiab hlau nplaum. Nyob rau hauv ib qho electromagnet, tam sim no dhau los ntawm lub kauj los tsim ib qho chaw sib nqus, sib nqus cov hlau ntshiab, yog li ua tiav kev tswj thiab siv cov hlau nplaum.
Transformers: Cov hlau ntshiab kuj tau siv dav hauv kev tsim cov transformer cores. Nyob rau hauv transformers, cov tub ntxhais hlau plays lub luag hauj lwm nyob rau hauv kis thiab transforming magnetic teb, thaum ntshiab hlau, vim nws siab conductivity thiab tsis tshua muaj hysteresis poob, yuav ua kom paub tseeb tias cov kev khiav hauj lwm zoo ntawm transformers.
Lub tshuab hluav taws xob thiab lub cev muaj zog: Hauv cov tshuab hluav taws xob thiab lub tshuab hluav taws xob, cov hlau ntshiab feem ntau yog siv los ua cov khoom tseem ceeb rau lub rotor lossis stator. Nyob rau hauv cov khoom siv no, tam sim no generates ib magnetic teb los ntawm coils, tsav lub rotor tig los yog tsim hluav taws xob, thaum lub siab conductivity thiab zoo mechanical zog ntawm cov hlau ntshiab ua rau nws yog ib qho zoo tagnrho xaiv.
4, Kev ua kom zoo ntawm kev coj ua ntawm cov hlau ntshiab
Txhawm rau txhim kho cov conductivity ntawm cov hlau ntshiab, cov kev ntsuas hauv qab no tuaj yeem siv:
Txhim kho purity: Los ntawm refining thiab purifying txheej txheem, cov impurity cov ntsiab lus nyob rau hauv cov hlau ntshiab yog txo, yog li txhim kho nws conductivity.
Optimizing lattice qauv: Los ntawm kev siv cov kev kho cua sov thiab lwm txoj kev ua, cov qauv lattice ntawm cov hlau ntshiab yog optimized los txo cov lattice defects thiab dislocations, txo cov cuam tshuam ntawm electrons, thiab yog li txhim kho conductivity.
Hauv cov ntsiab lus, cov hlau ntshiab tau siv dav hauv cov hluav taws xob vim nws cov conductivity zoo heev. Los ntawm optimizing yam xws li purity, lattice qauv, thiab kub ntawm ntshiab hlau, nws conductivity yuav tsum tau ntxiv txhim kho kom tau raws li cov kev xav tau ntawm ntau teb.
