Ib electrochemical cell yog ib qho khoom siv uas tsim kom muaj qhov sib txawv ntawm cov electrodes siv tshuaj lom neeg. Galvanic hlwb thiab electrolytic hlwb yog cov piv txwv ntawm electrochemical hlwb.
Kuj tseem paub yog, dab tsi yog electrochemical cell thiab nws ua haujlwm li cas?
Electrochemical hlwb siv tshuaj lom neeg los tsim hluav taws xob los yog hluav taws xob los ua kom muaj zog tshuaj lom neeg. Muaj ob hom: electrochemical hlwb siv lub zog siv los tsim cov tshuaj tiv thaiv; galvanic hlwb siv cov tshuaj tiv thaiv, feem ntau yog cov tshuaj tiv thaiv redox, los tsim hluav taws xob.
Ib yam li ntawd, electrochemical txhais li cas? Electrochemical cov tshuaj tiv thaiv, ib qho txheej txheem los yog ua ke los ntawm kev hla ntawm ib qho hluav taws xob tam sim no thiab koom nrog feem ntau qhov kev hloov ntawm electrons ntawm ob yam khoom-ib qho khoom thiab lwm yam kua.
Tom qab ntawd, hom electrochemical cell yog dab tsi?
Ob Hom ntawm Cell Muaj ob qhov tseem ceeb hom electrochemical cell : galvanic thiab electrolytic. Galvanic hlwb hloov tshuaj muaj peev xwm zog rau hauv hluav taws xob hluav taws xob. Hluav taws xob hlwb yog tsav los ntawm ib qho chaw sab nraud ntawm hluav taws xob hluav taws xob. Ib qho kev khiav ntawm electrons drives tsis-spontaneous (ΔG ≧ 0) redox cov tshuaj tiv thaiv.
Dab tsi yog txhais los ntawm electrolytic cell?
Ib electrolytic cell yog ib electrochemical cell uas tsav cov tshuaj tiv thaiv redox uas tsis yog tshwm sim los ntawm kev siv hluav taws xob hluav taws xob. Lawv feem ntau yog siv los decompose cov tshuaj sib txuas, hauv cov txheej txheem hu ua electrolysis - lus Greek lysis txhais tau tias kom tawg.

Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws cov DNA mus rau ob lub hlwb zoo tib yam
Dab tsi yog 2 qhov tseem ceeb ntawm lub voj voog ntawm tes thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Cov xwm txheej no tuaj yeem muab faib ua ob qhov tseem ceeb: interphase (hauv nruab nrab ntawm kev sib faib theem ua pawg G1 theem, S theem, G2 theem), thaum lub xov tooj ntawm tes tsim thiab ua nrog nws cov haujlwm metabolic; mitotic theem (M mitosis), thaum lub sij hawm lub cell yog replicating nws tus kheej
Lub ntsiab txhais ntawm cov cell hauv koj lub cev yog dab tsi?
Kev Kho Mob Txhais ntawm lub cev ntawm tes: lub nucleus-muaj qhov nruab nrab ntawm ib qho neuron tshwj tsis yog nws cov axons thiab dendrites uas yog cov qauv tseem ceeb ntawm cov teeb meem grey ntawm lub hlwb thiab qaum qaum, ganglia, thiab retina. - hu ua perikaryon, soma
Lub ntsiab lus ntawm cog cell thiab tsiaj cell yog dab tsi?
Tsiaj Thiab Nroj Tsuag Cell. Txhua yam muaj sia nyob, nroj tsuag lossis tsiaj txhu yog tsim los ntawm cov hlwb. Lub cytoplasm nyob rau hauv ib lub cell muaj chloroplast thiab lwm yam plastids, mitochondria, dictyosomes, ribosomes, du thiab ntxhib endoplasmic reticulum, nucleus thiab lwm yam. Ib tug tsiaj cell yog ntau dua los yog tsawg spherical
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
