Maxwell qhov sib npaug yog ib txheej ntawm plaub qhov sib txawv kev sib npaug uas tsim lub hauv paus theoretical rau piav txog classical electromagnetism : Ampère txoj cai: Tsis tu ncua tam sim no thiab lub sij hawm sib txawv hluav taws xob teb (qhov kawg vim yog Maxwell cov kho) tsim ib qho chaw sib nqus.
Kuj paub, Maxwell qhov sib npaug piav qhia txog cov hluav taws xob tsis zoo li cas?
Maxwell qhov sib npaug piav qhia ua li no nthwv dej muaj peev xwm propagate los ntawm qhov chaw. Kev hloov pauv magnetic teb tsim ib qho kev hloov hluav taws xob los ntawm Faraday txoj cai. Lub voj voog perpetual no tso cai rau cov no nthwv dej , tam sim no hu ua electromagnetic tawg , txav mus los ntawm qhov chaw ntawm qhov nrawm c.
Ib yam li ntawd, Maxwell thawj qhov sib npaug 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.
Qhov thib ob, lub ntsiab lus ntawm Maxwell qhov sib npaug yog dab tsi?
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. Tsis tas li ntawd, lawv piav qhia txog yuav ua li cas lub teb hluav taws xob tuaj yeem tsim ib qho chaw sib nqus, thiab rov ua dua. Thawj kev sib npaug tso cai rau koj los xam cov hluav taws xob hluav taws xob tsim los ntawm tus nqi.
Plaub Maxwell qhov sib npaug yog dab tsi?
Maxwell qhov sib npaug yog ib txheej ntawm plaub sib txawv kev sib npaug uas tsim lub hauv paus theoretical rau piav txog classical electromagnetism: Gauss txoj cai: Cov nqi hluav taws xob tsim hluav taws xob. Gauss txoj cai rau hlau nplaum: Tsis muaj hlau nplaum monopoles. Qhov sib nqus flux hla ntawm qhov chaw kaw yog xoom.

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
Qhov sib npaug sib npaug rau qhov nruab nrab ntawm h2so4 los ntawm Koh yog dab tsi?
Hauv daim vis dis aus no peb yuav sib npaug ntawm qhov sib npaug KOH + H2SO4 = K2SO4 + H2O thiab muab cov coefficients raug rau txhua qhov sib xyaw. Txhawm rau sib npaug KOH + H2SO4 = K2SO4 + H2O koj yuav tsum nco ntsoov suav tag nrho cov atoms ntawm txhua sab ntawm cov tshuaj sib npaug
Dab tsi yog qhov tseem ceeb ntawm cov coefficients hauv kev sib npaug sib npaug?
Coefficients yog ib qho tseem ceeb los ua pov thawj txoj cai ntawm kev txuag ntawm huab hwm coj. Cov coefficients nyob rau hauv ib qho kev sib npaug ntawm cov tshuaj sib npaug qhia cov txheeb ze ntawm moles ofreactants thiab cov khoom. Los ntawm cov ntaub ntawv no, lub Cheebtsam ntawm reactants thiab cov khoom yuav raug xam. Koj tuaj yeem txiav txim seb tus lej ntawm moles ntawm cov khoom
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
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
