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.

Lub luag haujlwm ntawm CDK yog dab tsi hauv lub cev ua haujlwm ntawm tes tshwj xeeb hauv lub voj voog ntawm tes?
Los ntawm phosphorylation, Cdks teeb liab lub xov tooj ntawm tes uas nws tau npaj kom dhau mus rau theem tom ntej ntawm lub voj voog ntawm tes. Raws li lawv lub npe qhia, Cyclin-Dependent Protein Kinases yog nyob ntawm cyclins, lwm chav kawm ntawm kev tswj hwm cov protein. Cyclins khi rau Cdks, ua kom cov Cdks rau phosphorylate lwm cov molecules
Dab tsi yog qhov txawv ntawm classical mechanics thiab quantum mechanics?
Nyob rau hauv luv luv, lub ntsiab sib txawv ntawm quantum thiab classical physics yog qhov txawv ntawm ib tug rampand ib staircase. Nyob rau hauv classical mechanics, cov xwm txheej (feem ntau) yog tas mus li, uas yog hais tias lawv txav mus rau hauv tus qauv, muaj kev sib haum xeeb thiab ua tau zoo. Qhov projectile motion yog ib qho piv txwv zoo ntawm classical mechanics
Dab tsi yog longitudinal waves ib hom yoj yoj rau?
Hauv cov lus yooj yooj yim, cov nthwv dej ntev yog hom nthwv dej ntawm qhov kev hloov pauv ntawm qhov nruab nrab yog nyob rau tib txoj kev uas cov nthwv dej txav mus. Qhov no txhais tau hais tias particle txav ntawm lub nthwv dej yuav sib npaug rau cov kev taw qhia ntawm lub zog txav
Dab tsi yog qhov tseem ceeb ntawm kev siv mechanics hauv kev ua haujlwm?
Nyob rau hauv cov tswv yim sciences, siv mechanics muaj txiaj ntsig hauv kev tsim cov tswv yim tshiab thiab kev xav, nrhiav pom thiab txhais cov xwm txheej, thiab tsim cov cuab yeej sim thiab suav
Cov txheej txheem dab tsi yog lub luag haujlwm rau txoj haujlwm ua haujlwm sib txawv?
Position-effect variegation (PEV) tshwm sim thaum cov noob ib txwm nyob hauv euchromatin yog sib xyaw nrog heterochromatin los ntawm kev hloov kho lossis hloov pauv. Thaum lub ntim ntim heterochromatin kis thoob plaws heterochromatin / euchromatin ciam teb, nws ua rau kev hloov pauv ntawm kev ntsiag to hauv tus qauv stochastic
