Periodic oscillations ntawm: kev txiav txim yooj yim yam ntxwv

Ntau ntau physics tej zaum tseem paub tsis meej. Thiab nws tsis yog ib txwm hais tias ib tug txiv neej cia li ib tug me ntsis kev nyeem ntawv rau cov kawm. Tej zaum cov ntaub ntawv uas yog muab li ntawd tus neeg to taub tias, yog tsis paub nrog cov qauv rau kev physics, nws tsuas yog tsis yooj yim sua. Ib tug es nthuav seem hais tias cov neeg tsis yeej ib txwm nkag siab txog cov thawj lub sij hawm thiab muaj peev xwm to taub, yog periodic oscillations. Ua ntej piav lub hom phiaj ntawm periodic oscillations, wb tham ib tug me ntsis txog keeb kwm ntawm lub foundations ntawm no phenomenon.

zaj dabneeg

Theoretical me nyuam yaus ntawm periodic oscillations twb paub nyob rau hauv lub ancient ntiaj teb no. Cov neeg pom raws li uniformly mus yoj raws li lub log tig, dhau los ntawm ib tug tej lub sij hawm ntawm lub sij hawm los ntawm lub taw tes tib yam. Nws yog vim hais tias ntawm cov yooj yim, thaum xub thawj siab ib muag, lub tswvyim ntawm teeb meem tshwm sim hesitation.

Thawj hesitation piav qhia txog lub pov thawj twb tsis tau fwm, tab sis nws yog lub npe hu hais tias ib tug ntawm feem ntau cov hom ntawm lawv (namely electromagnetic) raws kwv yees los ntawm Maxwell nyob rau hauv 1862. 20 xyoo tom qab, nws lub hom phiaj twb paub tseeb hais tias. Ces Genrih Gerts ua ib tug series ntawm thwmsim los ua pov thawj rau hauv lub hav zoov ntawm electromagnetic vuag thiab muaj ntawm tej yam thaj chaw uas yog tshwj xeeb rau lawv. Raws li nws muab tawm, lub teeb kuj yog ib qho electromagnetic yoj, thiab yog raug rau tag nrho cov kev cai. Ib tug ob peb xyoos ua ntej Hertz pom ib tug txiv neej uas pom hais tias nws lub scientific lub zej zog los ua kom muaj electromagnetic vuag, tab sis los ntawm virtue ntawm lub fact tias nws yog tsis muaj zog txaus nyob rau hauv kev tshawb xav raws li Hertz, yuav tsis ua pov thawj tias qhov kev paub ntawm kev vam meej yog piav los ntawm tus hloov mus hloov los.

Peb yog ib tug me ntsis deb ntawm lub npe. Nyob rau hauv lub tom ntej no tshooj lus no peb xav txog lub ntsiab piv txwv ntawm periodic oscillations, hais tias peb muaj peev xwm ua tau raws li nyob rau hauv lub neej txhua hnub thiab nyob rau hauv cov xwm.

Tej no tshwm sim qhov txhia chaw thiab lossi. Thiab dua li cov neeg twb muab nyob rau hauv ib qho piv txwv ntawm lub vuag thiab kev sib hloov ntawm lub log, peb yuav saib tau lub periodic hloov mus hloov los nyob rau hauv peb lub cev: lub plawv, lub zog ntawm lub teeb thiab thiaj li nyob. Yog hais tias koj zoom nyob rau hauv thiab tsiv mus nyob rau loj chaw tshaj peb lub cev, peb yuav saib tau lub hloov mus hloov los nyob rau hauv no science, zoo li biology.

Piv txwv yog periodic oscillations ntawm coob. Yuav ua li cas yog lub ntsiab lus ntawm no phenomenon? Nyob rau hauv txhua pejxeem, muaj yog ib txwm ib yam dab tsi ntawm nws nce, ces yuav txo tau. Thiab qhov no yog kev cob cog rua nrog lub cov ntaub ntawv los ntawm sib txawv yam. Vim lub chaw luag thiab ntau lwm yam tseem ceeb, cov pejxeem yuav tsis loj hlob indefinitely, li ntawd, siv tej yam ntuj tso xwm kawm tau mus txo tus naj npawb ntawm mechanisms. Thaum zoo li no tshwm sim thiab tus naj npawb ntawm periodic variations. Cov tib yam tshwm sim nrog tib neeg lub neej.

Peb tam sim no sib tham txog cov tswvyim no thiab qhov kev tshawb xav Cia peb kawm ib me ntsis qauv txog li no tshaj plaws li periodic oscillations.

kev tshawb xav

Periodic oscillations - ib tug heev interesting lub npe. Tab sis, raws li nyob rau hauv lwm yam, qhov ntxiv plunge - lub ntau obscure, tus tshiab thiab complex. Nyob rau hauv no tsab xov xwm peb yuav tsis delve tsuas qhia me ntsis txog qhov yooj yim thaj chaw ntawm lub deeg.

Lub ntsiab yam ntxwv yog periodic oscillation lub sij hawm thiab zaus ntawm oscillation. Lub sij hawm ntawd hais ntev npaum li cas koj xav kom yoj rov qab mus rau lub starting txoj hauj lwm. Nyob rau hauv qhov tseeb, nws yog lub sij hawm nyob rau hauv uas lub yoj mus rau hauv lub deb nruab nrab ntawm nws ib sab ridges. Yog lwm tus nqi uas yog zoo txog rau lub yav dhau los yog ib tug. Qhov no yog qhov zaus. Hom zaus lub sij hawm thiab muaj lub cev lub ntsiab lus: lub xov tooj ntawm crests ntawm tsis uas tau dhau los ntawm ib tug tej yam cheeb tsam ntawm lub chaw ib chav tsev lub sij hawm. Tus zaus ntawm periodic oscillations, Yog hais tias tam sim no nws nyob rau hauv lej daim ntawv no, muaj cov mis: v = 1 / T, qhov twg T - oscillation lub sij hawm.

Ua ntej koj yuav dhia mus rau lub xaus, qhia rau ib tug me ntsis txog qhov uas muaj periodic oscillations thiab yuav ua li cas paub txog lawv tej zaum yuav pab tau nyob rau hauv lub neej.

daim ntawv thov

Peb twb soj ntsuam cov hom ntawm periodic oscillations. Txawm hais tias kev coj los ntawm ib daim ntawv teev ntawm qhov chaw uas lawv muaj nyob, nws yog ib qho yooj yim to taub hais tias lawv yog cov tag nrho ib ncig ntawm peb qhov txhia chaw. Electromagnetic vuag tawm txim liab tag nrho peb cov khoom siv. Ntxiv mus, tus xov tooj kev twb kev txuas mus rau lub xov tooj los yog kev mloog mus rau lub xov tooj cua yuav tau tsis yooj yim sua yam uas tsis tau lawv.

Suab tsis kuj yog oscillations. Nyob rau hauv tus ntawm ib tug hluav taws xob voltage tshwj xeeb membrane nyob rau hauv tej suab generator pib co, tsim ib tug yoj ntawm ib tug tej zaus. Tom qab nyias nyias pib oscillate cov huab cua molecules, uas nyob rau hauv qhov kawg thiab mus txog peb lub pob ntseg thiab ntaus nqi raws li lub suab.

Physics - heev interesting science. Thiab txawm yog hais tias nws hais tias koj zoo ntawm paub nws txhua yam uas yuav pab tau nyob rau hauv lub neej txhua hnub, tseem muaj tshwm sim xws li ib tug tshaj plaws, uas yuav superfluous to taub zoo dua. Peb cia siab tias qhov no tsab xov xwm tau pab koj to taub thiab nco ntsoov cov khoom nyob rau hauv lub physics ntawm oscillations. Nws yeej yog ib tug heev ib qho tseem ceeb lub ntsiab lus, cov tswv yim daim ntawv thov ntawm cov kev tshawb xav ntawm uas yog nyob rau qhov txhia chaw hnub no.
