Lus txhais hauv tshuab hluav taws xob
Kev teeb tsa hluav taws xob kuj tseem hu ua kev teeb tsa hauv hluav taws xob. Nws yog lub cim ntawm lub xeev hluav taws xob ntawm atoms, ions lossis lwg me me. Raws li lub orbit kwv yees kwv yees ntawm quantum mechanics, txhua lub xaim hluav taws xob hauv ib qho atom, ion, lossis molecule raug txiav txim siab nyob hauv qee lub kiv thiab orbit lub xeev. Tag nrho cov xov tooj ntawm spins thiab orbits ntawm txhua qhov hluav taws xob hauv qhov system ua qhov hluav taws xob teeb tsa ntawm tag nrho cov kab ke.
