Mv txhais li cas hauv hluav taws xob?
Txheem
Raws li tus kws tshaj lij hluav taws xob uas qhia ntau tus tub ntxhais kawm, kuv pom ntau tus neeg tsis meej pem thaum lawv pom lo lus "MV" thiab nws txhais li cas hauv ib puag ncig hluav taws xob. Txij li nws tuaj yeem txhais tau ntau yam, Kuv yuav saib txhua yam hauv qab no.
MV tuaj yeem sawv ntsug rau ib qho ntawm peb yam hauv hluav taws xob.
- Megavolt
- Nruab nrab voltage
- Millivolt
Hauv qab no kuv yuav piav qhia txog peb lub ntsiab lus thiab muab piv txwv ntawm lawv siv.
1. Megavolt
Megavolt yog dab tsi?
Lub megavolt, los yog "MV," yog lub zog uas cov khoom siv hluav taws xob tau txais thaum nws dhau los ntawm qhov sib txawv ntawm ib lab volts hauv lub tshuab nqus tsev.
Kev siv megavolt
Lawv tau siv rau hauv cov tshuaj rau kev kho mob qog noj ntshav, neoplasms thiab qog nqaij hlav los ntawm kev kho hluav taws xob sab nraud. Cov kws kho mob hluav taws xob siv hluav taws xob siv cov kab hluav taws xob nrog lub zog ntawm 4 txog 25 MV los kho cov qog nqaij hlav hauv lub cev. Qhov no yog vim cov rays mus txog qhov tob ntawm lub cev zoo.
Megavolt X-rays yog qhov zoo dua rau kev kho cov kab mob sib sib zog nqus vim tias lawv poob qis zog dua li cov duab hluav taws xob qis dua thiab tuaj yeem nkag mus tob rau hauv lub cev nrog rau cov tawv nqaij qis dua.
Megavolt X-rays kuj tsis zoo rau cov khoom muaj sia xws li orthovoltage X-rays. Vim tias cov khoom zoo li no, megavolt x-rays feem ntau yog lub zog siv hluav taws xob ntau tshaj plaws siv hauv cov txheej txheem hluav taws xob niaj hnub xws li IMRT.
2. Nruab nrab voltage
Medium Voltage yog dab tsi?
Feem ntau, "qhov nruab nrab voltage" (MV) yog hais txog cov tshuab xa tawm saum toj 1 kV thiab feem ntau mus txog 52 kV. Rau cov laj thawj kev lag luam thiab kev lag luam, kev khiav hauj lwm voltage ntawm nruab nrab voltage tis network tsis tshua muaj tshaj 35 kV.
Kev siv hluav taws xob nruab nrab
Nruab nrab voltage muaj ntau yam siv thiab tus lej tsuas yog yuav loj hlob. Yav dhau los, nruab nrab voltage chav kawm voltages tau tsuas yog siv rau theem nrab kis tau tus mob thiab thawj tis.
Nruab nrab voltage feem ntau yog siv rau lub hwj chim faib transformers uas nqis los nruab nrab voltage mus rau tsawg voltage rau cov khoom siv fais fab kawg ntawm kab. Tsis tas li ntawd, nws yog dav siv nyob rau hauv kev lag luam rau motors nrog ib tug voltage ntawm 13800V los yog tsawg dua.
Tab sis cov txheej txheem tshiab topologies thiab semiconductors tau ua rau nws muaj peev xwm siv hluav taws xob hluav taws xob hauv nruab nrab voltage tes hauj lwm. Tsis tas li ntawd, cov kev faib tawm tshiab tau tsim nyob ib puag ncig nruab nrab voltage AC lossis DC los ua chaw rau cov khoom siv hluav taws xob tshiab thiab cov neeg siv.
3. Millivolts
millivolts yog dab tsi?
Millivolt yog ib chav tsev ntawm hluav taws xob muaj peev xwm thiab hluav taws xob hluav taws xob hauv International System of Units (SI). Millivolt sau ua mV.
Lub hauv paus chav tsev ntawm millivolts yog lub volt, thiab lub prefix yog "milli". Lub prefix milli los ntawm lo lus Latin rau "txhiab". Sau li m. Milli yog ib qho ntawm ib txhiab (1/1000), yog li ib volt sib npaug 1,000 millivolts.
Kev siv Millivolt
Millivolts (mV) yog units siv los ntsuas qhov voltage hauv hluav taws xob circuits. Nws yog sib npaug rau 1/1,000 volts los yog 0.001 volts. Chav tsev no tau tsim los ua kom yooj yim rau kev ntsuas thiab txo qhov tsis meej pem ntawm cov tub ntxhais kawm. Yog li ntawd, qhov thaiv no tsis yog feem ntau siv hauv kev lag luam hluav taws xob.
Ib millivolt yog ib txhiab ntawm ib volt. Nws yog siv los ntsuas qhov voltages me me. Qhov no tuaj yeem muaj txiaj ntsig zoo thaum tsim cov hluav taws xob hluav taws xob uas cov hluav taws xob me me yuav nyuaj dhau los ntsuas.
Summing txog
Hluav taws xob yog qhov nyuaj thiab hloov pauv txhua qhov chaw. Kuv vam tias tsab xov xwm no tau pab teb cov lus nug txog dab tsi Mv sawv cev rau hluav taws xob.
Ua tib zoo saib qee qhov ntawm peb cov lus hauv qab no.
