Peb theem vs ib theem
Peb theem fais fab thiab ib theem fais fab yog ob hom hluav taws xob uas peb siv hauv peb lub neej txhua hnub. Peb lub tsev khiav ntawm ib theem hluav taws xob thaum cov chaw tsim khoom siv hluav taws xob peb theem. Peb theem thiab ib-theem fais fab yuav tsum tau muaj nyob rau hauv cov teb xws li hluav taws xob engineering, industrial tsim thiab txawm yooj yim hauv tsev thaiv. Nws yog ib qho tseem ceeb kom muaj kev nkag siab zoo hauv cov ntsiab lus no kom ua tau zoo hauv cov teb uas muaj kev siv hnyav ntawm cov ntsiab lus no. Nyob rau hauv tsab xov xwm no, peb yuav tham txog dab tsi theem yog, dab tsi ib theem fais fab thiab peb theem fais fab yog, lawv cov ntsiab lus, kev siv, zoo sib xws, thiab thaum kawg qhov sib txawv ntawm peb theem fais fab thiab ib theem fais fab.
Ib Theem Lub Zog
Yuav kom nkag siab tias ib theem txhais tau li cas, peb yuav tsum xub to taub lub sij hawm theem. Ib txoj kev mus ncig tuaj yeem txhais tau siv qhov sib npaug Y (x, t)=A sin (ωt – kx), qhov twg Y (x, t) yog qhov txav ntawm y axis ntawm point x ntawm lub sijhawm t, A yog qhov amplitude ntawm nthwv dej, ω yog angular zaus ntawm nthwv dej, t yog lub sijhawm, k yog yoj vector, lossis qee zaum hu ua yoj tus lej, thiab x yog tus nqi ntawm x axis. Cov theem ntawm nthwv dej tuaj yeem txhais tau ntau txoj hauv kev. Feem ntau ib qho yog tias nws yog (ωt – kx) ib feem ntawm nthwv dej. Nws tuaj yeem pom tau tias ntawm t=0 thiab x=0, theem kuj tseem yog 0. Ib theem tam sim no tsuas muaj ib qho sinusoidal yoj xwb. Lub zog ib-theem yog qhov peb siv hauv peb lub tsev. Txij li cov khoom siv hauv peb lub tsev tsis tas yuav muaj lub zog tshwj xeeb, nws muaj kev nyab xeeb thiab pheej yig los siv ib-theem tam sim no.
Peb Phase Fais
Ib theem peb muaj peb lub sinusoidal nthwv dej, uas yog 120 ° lossis 2π / 3 radians tawm ntawm theem rau ib leeg. Peb-theem hluav taws xob fais fab yog txoj kev xa hluav taws xob ntau tshaj plaws. Peb theem hluav taws xob tam sim no ua rau lub zog tas li thoob plaws hauv lub voj voog. Yog li ntawd, qhov no yog heev haum rau hluav taws xob circuits nyob rau hauv industrial chaw. Thaum lub tshuab tig xws li lub tshuab dhos tshuab tig ntawm tib zaus raws li lub teeb ci, lub tshuab zoo li tsis tig. Peb-theem fais fab mov tuaj yeem daws qhov no los ntawm kev muab lub zog tas li thoob plaws lub voj voog. Peb lub nthwv dej ntawm peb theem tam sim no tuaj yeem sawv cev los ntawm Y1(x, t)=A sin (ωt – kx), Y2(x, t)=A sin (ωt – kx-2π/3) thiab Y3(x, t)=A sin (ωt – kx-4π/3). Thawj theem ntawm Y1 nthwv dej yog suav tias yog xoom.
Qhov txawv ntawm Ib Theem thiab Peb Theem yog dab tsi?
• Ib theem tsuas muaj ib qho sinusoidal tam sim no thiab ib qho sinusoidal voltage. Peb-theem fais fab muaj peb lub sinusoidal tam sim no uas yog 2π / 3 radians tawm ntawm theem rau ib leeg.
• Lub zog tam sim ntawd dissipation ntawm ib-theem fais fab yog nyob ntawm lub sij hawm thiab qhov tsis kam. Lub zog dissipation ntawm peb-theem fais fab mov yog tas li.
