Qhov tshwm sim no yog hu ua lub zog xoom lossis xoom taw tes taw tes, thiab nws sawv hauv qhov sib txawv ncaj qha rau daim duab classical ntawm lub vibrating molecule. Classically, lub zog qis tshaj plaws muaj rau lub oscillator yog xoom, uas txhais tau tias lub zog kuj yog xoom, thiab oscillator tsis txav.
Yuav ua li cas lub harmonic oscillator puas muaj pes tsawg lub zog?
Kev hloov pauv muab tus nqi qis kawg ntawm lub zog tso cai. Qhov no yog qhov tshwm sim ntawm lub cev tseem ceeb heev vim nws qhia peb tias lub zog ntawm lub cev tau piav qhia los ntawm harmonic oscillator peev xwm tsis tuaj yeem muaj lub zog xoom.
txhais li cas los ntawm xoom-point zog?
Zero-point zog, vibrational zog uas molecules khaws cia txawm nyob rau ntawm qhov tsis muaj tseeb ntawm qhov kub thiab txias. … Tab sis nws yog ib qho axiom ntawm quantum mechanics uas tsis muaj ib yam khoom twg muaj peev xwm muaj qhov tseeb ntawm txoj hauj lwm thiab qhov nrawm ib txhij (saib cov ntsiab lus tsis meej); yog li cov molecules yeej tsis tuaj yeem so kiag li.
Lub zog ntawm harmonic oscillator yog dab tsi?
Nyob rau hauv ib qho yooj yim harmonic oscillator, lub zog oscillates ntawm kinetic zog ntawm pawg K=12mv2 thiab muaj peev xwm zog U=12kx 2 khaws cia rau lub caij nplooj ntoo hlav. Nyob rau hauv lub SHM ntawm lub loj thiab lub caij nplooj ntoos hlav system, tsis muaj dissipative rog, yog li tag nrho cov zog yog cov sum ntawm lub peev xwm zog thiab kinetic zog.
Dab tsi yog cheeb tsam txwv?
Nyob ibCov cheeb tsam txwv tsis pub muaj zog,lub zog ntawm quantum particle tsawg dua li lub zog muaj peev xwmkom lub quantum yoj ua haujlwm tsis tuaj yeem nkag mus rau thaj tsam txwv tshwj tsis yog nws qhov loj me dua qhov kev lwj ntev ntawm quantum yoj. muaj nuj nqi.
