Wave muaj nuj nqi, hauv quantum mechanics , variablequantity uas lej piav txog qhov yoj yam ntxwv ntawm ib tug particle. Tus nqi ntawm cov wavefunction ntawm ib qho particle ntawm ib qho chaw ntawm qhov chaw thiab lub sijhawm muaj feem cuam tshuam rau qhov yuav tshwm sim ntawm qhov particle nyob rau lub sijhawm ntawd.

Ib yam li ntawd, koj tuaj yeem nug, yoj ua haujlwm hauv cov lus yooj yim yog dab tsi?

Wave muaj nuj nqi . Los ntawm Wikipedia, lub freeencyclopedia. Hauv quantum mechanics, lub Wave muaj nuj nqi , feem ntau sawv cev los ntawm Ψ, lossis ψ, piav qhia qhov tshwm sim ntawm kev nrhiav ib qho hluav taws xob nyob rau hauv nws qhov teeb meem yoj.

Tsis tas li ntawd, yoj haujlwm yog dab tsi thiab nws qhov tseem ceeb ntawm lub cev? Cov yoj ua haujlwm 'Ѱ' tsis muaj lub ntsiab lus ntawm lub cev . Nws yog ib tug complex kom muaj nuj nqis sawv cev rau variation ntawm ib qho teeb meem yoj . Cov yoj ua haujlwm Ѱ(r, t) piav qhia txog txoj hauj lwm ntawm particle nrog rau lub sij hawm. Nws tuaj yeem suav tias yog 'PROBABILITY AMPLITUDE' vim nws yog siv los nrhiav qhov chaw ntawm cov khoom.

Dab tsi yog qhov ua haujlwm ntawm lub tshuab hluav taws xob?

Lub ntsiab lus ntawm lub cev yoj ua haujlwm yog ib qho tseem ceeb txhais teeb meem ntawm quantum mechanics. Tus qauv assumption yog tias tus wave function ntawm ib tug electron yog aprobability amplitude, thiab nws modulus square muab qhov probabilitydensity ntawm nrhiav cov hluav taws xob nyob rau hauv ib qho chaw ntawm agven instant.

Dab tsi txhais li cas?

Ψ Cov ntsiab lus tseem ceeb, xws li cov khoom siv hluav taws xob, tuaj yeem piav qhia raws li cov khoom siv lossis cov nthwv dej. Cov hluav taws xob tuaj yeem piav qhia txog kev ua haujlwm nthwv dej. Lub cim nthwv dej ua haujlwm yog tsab ntawv Greek psi, Ψ los yog ψ . Lub zog ua haujlwm Ψ yog kev qhia lej.
