Maxwell qhov sib npaug piav qhia txog cov nqi hluav taws xob thiab hluav taws xob li cas tsim hluav taws xob thiab sib nqus teb. Thawj kev sib npaug tso cai rau koj los xam cov hluav taws xob hluav taws xob tsim los ntawm tus nqi. Qhov thib ob tso cai rau koj los xam cov magnetic teb. Lwm ob piav qhia txog yuav ua li cas teb 'kho' ncig lawv qhov chaw.
Ua kom pom qhov no, plaub Maxwell qhov sib npaug yog dab tsi?
Maxwell's Equations
- Gauss txoj cai: Cov nqi hluav taws xob tsim hluav taws xob.
- Gauss txoj cai rau hlau nplaum: Tsis muaj hlau nplaum monopoles.
- Faraday txoj cai: Lub sijhawm sib txawv ntawm cov hlau nplaum tsim hluav taws xob.
- Ampère txoj cai: Cov dej ntws tsis tu ncua thiab lub sijhawm sib txawv ntawm cov hluav taws xob hluav taws xob (tom kawg vim Maxwell qhov kev kho) tsim cov hlau nplaum.
Kuj Paub, vim li cas lawv hu ua Maxwell qhov sib npaug? 3 Teb. Raws li koj pom, cais kev sib npaug muaj lwm lub npe thiab. Maxwell cov ntxiv lub sij hawm hloov chaw ua rau lub kaw lus ua tiav, nrog rau tag nrho cov txiaj ntsig tseem ceeb, tshwj xeeb, uas twb muaj lawm ntawm electromagnetic tsis. Yog li lub npe ntawm tag nrho cov system tom qab Maxwell yog ncaj ncees kiag li.
Ntawm no, Maxwell thawj kab zauv yog dab tsi?
1. Qhov no kev sib npaug hais tias qhov hluav taws xob ua haujlwm zoo los ntawm qhov chaw ntim ib lub ntim yog sib npaug rau tag nrho cov nqi hauv lub ntim. Kom nco ntsoov daim ntawv tseem ceeb ntawm Maxwell's Equation No. 1, xav tias ib tug nqi q, nyob rau hauv ib lub ntim, yuav tsum sib npaug zos rau lub ntim nqi ceev, r, lub sij hawm lub ntim.
Dab tsi yog qhov sib npaug rau lub teeb?
Formula: c = f qhov twg: c = qhov ceev ntawm teeb = 300,000 km/s lossis 3.0 x 108 m/s. = lub wavelength ntawm teeb , feem ntau ntsuas hauv meters lossis Ångströms (1 Å = 10-10 m)

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Puas yog txhua qhov sib npaug sib npaug sib npaug?
Thawj qhov sib npaug sib npaug yog qhov tseeb yog tias nws muaj kev txuag kom muaj nuj nqis. Piv txwv li, qhov sib npaug sib cais yeej ib txwm muaj tseeb, txij li lub ntsiab lus lawv yog ntawm daim ntawv: M(y) + N(t) = 0, yog li ϕ(t, y) = A(y) + B(t) yog a khaws cia kom muaj nuj nqis
Qhov sib npaug tshuaj sib npaug txhais li cas?
Cov tshuaj sib npaug yuav tsum sib npaug kom nws ua raws li txoj cai ntawm kev txuag ntawm huab hwm coj. Ib qho kev sib npaug tshuaj sib npaug tshwm sim thaum tus naj npawb ntawm cov atoms sib txawv ntawm cov ntsiab lus hauv cov reactants sab sib npaug ntawm cov khoom sab. Kev sib npaug tshuaj sib npaug yog cov txheej txheem ntawm kev sim thiab ua yuam kev
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
