Pom nyob rau hauv ib co Cov khoom siv hlau nplaum , saturation yog lub xeev mus txog thaum muaj kev nce ntxiv hauv kev sivexternal Sib nqus teb H tsis tuaj yeem nce qhov magnetization ntawm khoom ntxiv, yog li tag nrho Sib nqus fluxdensity B ntau dua los yog tsawg dua. (Nws tseem nce qeeb heev vim lub tshuab nqus tsev permeability.)
Kuj nug, dab tsi yog txhais los ntawm core saturation?
Core Saturation . transformer saturation ” Ib qho xwm txheej qhov twg transformer's tub ntxhais yog magnetized tag nrho thiab yog tsim ntau magneticflux. Qhov no feem ntau tshwm sim thaum lub transformer tsis loj txaus rau daim ntawv thov.
Tsis tas li ntawd, dab tsi yog saturation hauv hysteresis? Ib qho piv txwv hysteresis lub voj yog qhia hauv qab no. Theloop yog tsim los ntawm kev ntsuas qhov sib nqus ntawm cov khoom siv ferromagnetic thaum lub zog magnetizing hloov. Cov khoom tau ncav cuag qhov sib nqus saturation . Thaum H raug txo qis rau xoom, qhov nkhaus yuav txav ntawm taw tes "a" mus rau taw tes "b."
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog lub zog quab yuam hauv hlau nplaum?
Coercive quab yuam los yog kev quab yuam. Qhov no txhais tau tias tus nqi ntawm sab nraud magnetic teb uas coj mus rau xoom themagnetization los yog Sib nqus flux ceev a Sib nqus lub cev thaum uas sab nraud magnetic teb yog tshwm sim los ua hauj lwm nyob rau hauv lub opposite kev taw qhia los ntawm orientation ntawm lub magnetization ntawm lub Sib nqus lub cev.
Yuav ua li cas thaum lub transformer saturates?
Thaum cov inductance txo qis, qhov kev tiv thaiv tiv thaiv nrog rau qhov tam sim no tsuas yog qhov tsis kam ntawm qhov transformer windings. Ntawd yog, thaum lub transformer mus txog saturation , ib tug loj tam sim no ntws. Qhov no yog vim li cas thaum saturation ntawm transformer yog ib qho teeb meem hauv powersupply design.

6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Dab tsi yog qhov zoo sib xws ntawm cov khoom thiab cov khoom sib txuas?
Cov ntsiab lus thiab cov tebchaw yog cov tshuaj homogeneous nkaus xwb thiab lawv muaj qhov sib xyaw tas li thoob plaws. Cov ntsiab lus thiab cov tebchaw tsis tuaj yeem sib cais rau hauv lawv cov khoom sib xws los ntawm kev siv lub cev. Cov tshuaj thiab cov khoom sib tov yog tsim los ntawm cov khoom sib txawv lossis cov atom sib txawv
Cov piv txwv ntawm kev sib nqus sib nqus yog dab tsi?
Tsis yog tag nrho cov hlau yog hlau nplaum; kub, nyiaj thiab txhuas yog ib co piv txwv. Ib qho kev sib txawv loj ntawm kev siv tshuab yog siv los cais cov khoom sib nqus. Thaum sib nqus sib nqus, cov hlau nplaum nyob hauv ob lub nruas sib nqus uas dais kua
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
