Thaum lub dielectric muab tso rau tag nrho nruab nrab ob tug daim hlau ntawm capacitor ces yog dielectric tas li nce los ntawm nws tus nqi nqus tsev vacuum. Yog li, thiab, yog qhov kev tso cai ntawm cov khoom.
Xav txog qhov no, yuav ua li cas thaum lub dielectric tso rau hauv lub capacitor?
Ntxiv ib dielectric tso cai rau capacitor khaws cov nqi them ntau dua rau qhov muaj peev xwm sib txawv. Thaum a dielectric yog muab tso rau hauv tus nqi capacitor , cov dielectric yog polarized los ntawm teb. Electric teb los ntawm dielectric yuav ib feem tshem tawm hluav taws xob teb los ntawm tus nqi ntawm lub capacitor daim hlau.
Tom qab ntawd, lo lus nug yog, lub luag haujlwm ntawm cov khoom siv nruab nrab yog dab tsi yog tias nws muab tso rau ntawm daim phiaj ntawm lub capacitor? Cov khoom nruab nrab yog lub dielectric muab tso rau nruab nrab ob hlau daim hlau ntawm lub capacitor . Ntau hom dielectric nruab nrab yog siv rau ntau hom capacitor . Dielectric los yog insulating nruab nrab yog siv rau lub zog hauv nws. Dielectric los yog insulating nruab nrab yog siv rau lub zog hauv nws.
Tsis tas li ntawd, puas muaj cov khoom siv uas thaum muab tso rau ntawm daim hlau ntawm lub capacitor txo nws cov peev xwm?
Dielectrics. nruj me ntsis hais lus, cov lus qhia (108) rau lub capacitance ntawm ib lub phaj parallel capacitor tsuas yog siv tau yog tias cheeb tsam nruab nrab ntawm daim phiaj yog lub tshuab nqus tsev. Dielectric cov ntaub ntawv muaj cov nyhuv ntawm txo cov chaw hluav taws xob thiab qhov sib txawv muaj peev xwm tsim los ntawm cov nqi hluav taws xob.
Thaum twg cov khoom siv dielectric raug qhia?
Taw qhia dielectric nruab nrab ntawm cov phaj capacitor (nyob rau hauv qhov chaw ntawm huab cua) yuav ua rau kom tus nqi capacitor los ntawm ib qho tseem ceeb ntawm dielectric tas li. Yog hais tias nws yog ib qho kev rho tawm capacitor, tus nqi tseem zoo ib yam, thiab qhov hluav taws xob poob qis hauv qhov sib piv rau dielectric tas li.

Cov khoom twg yog cov piv txwv ntawm cov khoom siv tshuaj xyuas txhua yam uas siv?
Piv txwv ntawm cov khoom siv tshuaj muaj xws li flammability, toxicity, acidity, reactivity (ntau hom), thiab kub ntawm combustion. Hlau, piv txwv li, ua ke nrog oxygen nyob rau hauv lub xub ntiag ntawm dej los ua xeb; chromium tsis oxidize (Daim duab 2)
Dab tsi nthwv dej zoo li cov cuab yeej ntawm lub teeb ua rau nws hloov kev taw qhia thaum nws txav ntawm ib nrab mus rau lwm qhov?
Refraction
Yuav ua li cas tshwm sim rau lub parallel phaj capacitor thaum lub dielectric muab tso rau ntawm daim hlau?
Thaum cov khoom siv dielectric tau qhia nruab nrab ntawm daim hlau Thiab thaum cov khoom siv dielectric muab tso rau nruab nrab ntawm daim hlau ntawm cov paib sib npaug ntawm cov phaj capacitor ces vim polarization ntawm cov nqi ntawm ob sab ntawm dielectric, nws tsim hluav taws xob teb ntawm nws tus kheej uas ua nyob rau hauv ib qho kev taw qhia opposite. rau lub teb vim
Yuav ua li cas cov khoom siv caj ces hauv txhua lub xov tooj tshiab tsim los ntawm kev faib tawm ntawm tes sib piv nrog cov khoom siv caj ces hauv lub xov tooj qub?
Mitosis tshwm sim nyob rau hauv ob lub nuclei uas zoo tib yam rau thawj nucleus. Yog li, ob lub hlwb tshiab tsim tom qab kev faib tawm ntawm tes muaj tib yam khoom siv caj ces. Thaum lub sij hawm mitosis, chromosomes condense los ntawm chromatin. Thaum saib nrog lub microscope, chromosomes pom nyob rau hauv lub nucleus
Dab tsi yog qhov txawv ntawm cov khoom siv organic thiab cov khoom siv organic?
Dab tsi yog qhov txawv ntawm cov khoom siv organic thiab organic teeb meem? Organic khoom yog txhua yam uas tseem muaj sia nyob thiab tam sim no nyob rau hauv lossis hauv av. Rau nws los ua cov organic teeb meem, nws yuav tsum tau decomposed rau hauv humus. Humus yog cov khoom siv organic uas tau hloov dua siab tshiab los ntawm cov kab mob mus rau lub xeev tsis muaj zog
