Qhov sib txawv tseem ceeb ntawm kev tshawb xav classical thiab quantum theory yog qhov kev tshawb xav classical piav txog qhov xwm txheej ntawm qib macroscopic, qhov kev xav ntawm quantum piav qhia qhov xwm txheej ntawm qib microscopic.
Qhov kev tshawb xav classical thiab quantum txoj kev xav yog cov ceg tseem ceeb hauv lub cev chemistry vim peb tuaj yeem siv lawv los piav txog tus cwj pwm ntawm cov khoom. Muaj qhov sib txawv tseem ceeb ntawm kev tshawb xav classical thiab quantum theory, nrog rau kev kwv yees ntawm cov xwm txheej nrog rau cov khoom uas tau txiav txim siab, piv txwv li kev tshawb xav classical yog siv rau cov khoom siv macroscopic qhov twg txoj kev xav quantum piav qhia txog tus cwj pwm yog tias microscopic hais.
Dab tsi yog Classical Theory?
Txoj kev xav classical ntawm mechanics yog ib txoj kev xav uas piav txog qhov kev txav ntawm cov khoom macroscopic. Hom macroscopic khoom yuav txawv ntawm qhov projectiles mus rau cov khoom siv hnub qub xws li cov khoom siv hauv chaw. Cov xwm txheej ntawm kev txav mus los yog kwv yees raws li kev xav classical. Qhov ntawd txhais tau hais tias, yog tias peb paub qhov pib lub xeev ntawm cov khoom, peb tuaj yeem kwv yees nws lub xeev yav tom ntej thiab txiav txim siab seb nws lub xeev yav dhau los; Hauv lwm lo lus, peb tuaj yeem twv seb qhov khoom yuav txav mus li cas thiab nws tsiv li cas yav dhau los.

Feem ntau, kev tshawb xav classical muab cov txiaj ntsig zoo heev rau cov khoom loj. Txawm li cas los xij, qhov kev xav no tsis ua haujlwm rau cov khoom loj heev thiab cov khoom txav ze ntawm lub teeb nrawm.
Quantum Theory yog dab tsi?
Quantum txoj kev xav yog ib txoj kev xav uas piav txog qhov xwm ntawm cov khoom ntawm qib atomic. Raws li quantum txoj kev xav, lub zog, lub zog, thiab lub zog angular yog qhov tseem ceeb; peb hu nws "quantized". Ntawm no, cov khoom muaj ob qho tib si yoj thiab particle xwm. Qee zaum, qhov no yog tib txoj kev xav uas tuaj yeem piav qhia tus cwj pwm ntawm subatomic hais - electrons, protons, thiab lwm yam.

Tsis tas li ntawd, qhov kev xav no tseem ceeb hauv kev txiav txim siab yuav ua li cas atoms khi rau ib leeg ntawm covalent bonding. Tsis tas li ntawd, cov teb uas siv quantum txoj kev xav muaj xws li electronics, cryptography, quantum xam, thiab lwm yam.
Qhov txawv ntawm Classical Theory thiab Quantum Theory yog dab tsi?
Classical theory of mechanics is a theory uas piav txog kev txav ntawm cov khoom macroscopic thaum quantum theory yog ib txoj kev xav uas piav txog qhov xwm txheej ntawm cov khoom ntawm qib atomic. Yog li, qhov sib txawv tseem ceeb ntawm kev tshawb xav classical thiab quantum theory yog qhov kev tshawb xav classical piav txog qhov xwm txheej ntawm qib macroscopic whereas quantum theory piav qhia qhov xwm txheej ntawm qib microscopic. Tsis tas li ntawd, txoj kev xav classical tsis piav txog yoj-particle dual thaum quantum txoj kev xav tsis piav txog yoj-particle dual.
Ntxiv mus, qhov sib txawv ntxiv ntawm classical thiab quantum txoj kev xav yog tias cov xwm txheej yav tom ntej tuaj yeem kwv yees tau yog tias peb siv txoj kev xav classical, tab sis raws li quantum txoj kev xav, cov xwm txheej tsis tuaj yeem twv tau.
Summary – Classical Theory vs Quantum Theory
Classical theory thiab quantum theory yog qhov tseem ceeb theories hauv lub cev chemistry. Qhov sib txawv tseem ceeb ntawm kev tshawb xav classical thiab quantum txoj kev xav yog qhov kev tshawb xav classical piav qhia txog qhov xwm txheej ntawm qib macroscopic, whereas quantum theory piav qhia qhov xwm txheej ntawm qib microscopic.
