Ntau lawm Muaj peev xwm yog lub ntim ntawm cov khoom los yog cov kev pabcuam uas tuaj yeem tsim los ntawm kev lag luam uas siv cov peev txheej tam sim no. Siv tau muaj peev xwm : Siv tau muaj peev xwm yog qhov siab tshaj plaws tau tso zis tau muab txwv xws li kev xav tau zoo, khoom sib tov muaj pes tsawg leeg, tshuab tu thiab teem caij teeb meem.
Ua li no, qhov system muaj peev xwm yog dab tsi?
Qhov system muaj peev xwm yog raug cai txhais raws li qhov siab tshaj plaws ntawm cov khoom ntawm tus naj npawb ntawm cov neeg siv ib lub sij hawm ntawm tes tus neeg siv spectral efficiency rau ib tug muab qhov siab tshaj plaws outage probability.
Ib yam li ntawd, qhov sib txawv ntawm cov peev txheej yog dab tsi? Nyob rau hauv cov saw hlau optimization thiab kev tsim khoom thiab kev tswj hwm kev tsim khoom, muaj peb lub tswv yim muaj peev xwm siv los ntawm cov koom haum sib txawv thaum lawv xav txog kev xav tau ntau ntxiv:
- Lub tswv yim muaj peev xwm ua tau.
- Lub lag peev txheej zoo.
- Qhov kev sib tw muaj peev xwm zoo.
Tsis tas li ntawd, qhov peev xwm nrog piv txwv yog dab tsi?
Lub ntsiab txhais ntawm muaj peev xwm yog lub peev xwm ntawm ib tug neeg los yog ib yam dab tsi los tuav ib yam dab tsi. Ib piv txwv ntawm muaj peev xwm yog pes tsawg tus neeg tuaj yeem haum hauv ib chav. Ib piv txwv ntawm muaj peev xwm yog cov dej ib khob tuav tau.
Vim li cas lub peev xwm tseem ceeb?
Muaj peev xwm kev siv yog ib qho tseem ceeb tswvyim: Nws feem ntau yog siv los ntsuas qhov kev ua tau zoo. Cov nqi tsim khoom nruab nrab yuav poob qis thaum cov khoom siv tau nce - yog li kev siv ntau dua tuaj yeem txo cov nqi tsev, ua rau kev lag luam muaj kev sib tw.

Cov khoom puas muaj ob qho tib si kinetic thiab lub zog muaj peev xwm?
Ib yam khoom muaj peev xwm muaj ob qho tib si kinetic thiab lub zog muaj peev xwm tib lub sijhawm. Piv txwv li, ib yam khoom uas poob, tab sis tseem tsis tau mus txog hauv av muaj lub zog kinetic vim nws txav mus rau hauv qab, thiab lub zog muaj peev xwm vim tias nws muaj peev xwm txav mus rau hauv qab txawm tias nws twb muaj lawm
Dab tsi yog 5 hom kev muaj peev xwm muaj zog?
Kev nthuav qhia, 5 Hom Muaj Peev Xwm Muaj Zog. Lub zog muaj peev xwm yog khaws cia lub zog uas tuaj yeem hloov mus rau kinetic zog. Muaj ntau hom kev siv zog xws li gravitational, magnetic, hluav taws xob, tshuaj, thiab elastic muaj peev xwm zog
Dab tsi yog qhov txawv ntawm electrostatic muaj peev xwm thiab electrostatic muaj peev xwm zog?
Tsis muaj qhov sib txawv ntawm electrostatic potentialenergy thiab hluav taws xob (al) muaj peev xwm zog. Lub peev xwm hluav taws xob ntawm ib qho taw tes yog kev ua haujlwm los ntawm lwm qhov kev quab yuam hauv kev txav chav tsev zoo los ntawm ib qho arbitrarilychosen xoom ntawm lub peev xwm (feem ntau infinity) mus rau lub ntsiab lus
Puas muaj peev xwm hluav taws xob thiab lub zog muaj peev xwm tib yam Vim li cas lossis vim li cas ho tsis?
Lub zog muaj peev xwm hluav taws xob Ue yog lub zog muaj peev xwm khaws cia thaum cov nqi tawm ntawm qhov sib npaug (xws li lub zog muaj peev xwm gravitational). Lub peev xwm hluav taws xob zoo ib yam, tab sis ib tus nqi, Ueq. Ib qho hluav taws xob muaj peev xwm sib txawv ntawm ob lub ntsiab lus hu ua voltage, V = Ue2q−Ue1q
Puas muaj peev xwm equilibrium zoo ib yam li so muaj peev xwm?
Qhov sib txawv ntawm daim nyias nyias muaj peev xwm thiab qhov muaj peev xwm sib npaug (-142 mV) sawv cev rau lub zog hluav taws xob hluav taws xob uas tsav Na + mus rau hauv lub xovtooj ntawm lub peev xwm so membrane. Thaum so, txawm li cas los xij, qhov permeability ntawm daim nyias nyias mus rau Na + tsawg heev kom tsuas yog me me Na + xau rau hauv lub cell
