Cov ntsiab lus ntawm kev ua hlau nplaum
Hlau nplaum yog lub cev kom muaj nuj nqis uas qhia txog qib uas sib nqus muaj zog ntawm lub cev loj kawg. Hauv tshuab hluav taws xob classical, magnetization lossis sib nqus polarization yog vector teb uas sawv cev los ntawm qhov chaw ruaj khov lossis dipole sib nqus lub caij muaj hlau nplaum. Feem ntau qhia los ntawm lub cim M. Nws yog txhais raws li piv ntawm qhov tawm ntawm cov vectors ntawm lub sij hawm sib nqus ntawm txhua lub lwg me me hauv nruab nrab voxel me me ΔV rau ΔV.
