Cyclic zaus - dab tsi thiab yuav ua li cas?

Nyob rau hauv lub ntiaj teb no nyob ib ncig ntawm peb, muaj ntau ntau yam tshwm sim thiab cov txheej txheem, uas yog, los ntawm thiab loj, invisible, tsis yog vim lawv tsis muaj nyob, tab sis tsuas yog vim peb tsis pom lawv. Lawv yog cov yeej ib txwm tam sim no thiab yog tib yam invisible thiab indispensable essence ntawm tej yam, tsis muaj uas peb lub neej thiab nws yog ib qhov nyuaj rau xav txog tej yam. Txhua, piv txwv li, nws yog lub npe hu hais tias xws li fluctuation: nyob rau hauv nqe lus dav dav - ib tug txawv los ntawm cov equilibrium lub xeev. Zoo, qhov ntxeev ntawm lub Ostankino ntauwd nraum rau lawv 5 th, thiab ces zoo li cas? Thiab hardens? Tsis muaj dab tsi zoo li no yuav pib rov qab los, tiab hauv qab equilibrium thiab yuav deflected nyob rau hauv kev coj rov qab, thiab thiaj li nyob mus ib txhis, ntev li ntev raws li nws yuav ua ib ke. Thiab qhia rau kuv, ib tug ntau ntawm cov neeg tau pom cov heev loj hloov mus hloov los zoo li no loj loj lug? Sawv daws yeej paub nws txawv, nyob ntawm no, muaj, ntawm no, muaj, hnub thiab hmo ntuj, lub caij ntuj no thiab lub caij ntuj sov, tab sis xyov ... tsis ntau. Yog vim li cas rau lub oscillatory txheej txheem - yog lwm cov teeb meem, tab sis nws muaj yog - ib tug inseparable cwj pwm ntawm tag nrho cov yam.

Yog hom twg tag nrho cov nyob ib ncig ntawm: vaj tse, pendulum moos, cov nplooj rau cov ntoo, nkauj laus ncas hlua, cov nplaim dej hiav txwv, ob txhais ceg ntawm cov diav rawg ... Cov hloov mus hloov los txawv chaotic uas tsis muaj kev cai nruj heev repeatability, thiab cyclic, uas rau ib lub sij hawm lub sij hawm T oscillating lub cev kis tau ib tug tag nrho teev ntawm nws hloov, thiab ces lub voj voog yog raws nraim tib yam, feem ntau hais lus, indefinitely. Feem ntau, cov kev hloov no hais ib zaj scan ntawm spatial coordinates, raws li tau pom nyob rau hauv lub oscillations ntawm lub pendulum, los yog cov tib pej thuam.

Tus nab npawb ntawm oscillations ib chav tsev lub sij hawm no yog hu ua cov zaus F = 1 / T. Zaus ntsuas unit - Hz = 1 / s. Nws yog tseeb hais tias cov cyclic zaus yog ib tug parameter ntawm tib lub npe hesitation ntawm txhua yam. Txawm li cas los, nyob rau hauv kev xyaum, nws txais cov tswvyim no, muaj ib co ntxiv txog feem ntau mus rau lub sib hloov mus los xwm ntawm lub hloov mus hloov los. Nws thiaj li tau tshwm sim nyob rau hauv lub kos duab hais tias tus muab lub zog yog lub hauv paus ntawm feem ntau ntawm cov tshuab, cov cuab yeej, pab kiag li lawm. Rau ib tug lub voj voog ntawm oscillation ntawm ib tug tig, thiab ces nws yog ntau yooj yim rau siv lub angular xaav tsis. Raws li, qhov muab zog ntsuas angular units, i.e. ib kiv puag ncig yog sib npaug zos rau 2π radians, thiab cov cyclic zaus ῳ = 2π / T. Ntawm no qhia c yog nkag khees kev sib txuas lus zaus F: ῳ = 2πF. Qhov no ua rau nws tau hais tias cov cyclic zaus - lub xov tooj ntawm oscillations (full lem) dua 2π vib nas this.

Nws yuav zoo li, nws tsis yog nyob rau hauv lub hauv pliaj, yog li ... Tsis tshua. 2π multipliers thiab 2πF siv nyob rau hauv ntau electronics sib npaug, zauv thiab theoretical physics nyob rau hauv lub khej twg lub oscillatory dab yog kawm siv lub tswvyim ntawm cyclic zaus. Cov mis ntawm lub resonance zaus, piv txwv li, yog txo los ntawm ob yam tseem ceeb. Nyob rau hauv cov ntaub ntawv ntawm siv nyob rau hauv lub xam chav tsev "vol. / Sec" angular, cyclic zaus ῳ txaus coincides nrog rau cov nqi ntawm cov zaus F.

Hloov mus hloov los, raws li cov essence thiab hauv daim ntawv ntawm cov hav zoov ntawm qhov teeb meem, thiab nws tiag tiag incarnation - kawm ntawm peb hais tias yog ntawm kuj zoo kawg tseem ceeb nyob rau hauv tib neeg lub neej. Paub txog cov kev cai ntawm deeg tau los mus tsim advanced electronics, hluav taws xob engineering, muaj ntau yam ntawm cov niaj hnub machine. Tu siab, lub hloov mus hloov los yeej tsis coj ib tug zoo ntxim, tej zaum lawv coj kev nyuaj siab thiab kev puas tsuaj. Unaccounted oscillations ua ntawm ntau raug xwm txheej, ua rau ntxov ntxov laus ntawm tus cov ntaub ntawv, thiab cov angular zaus ntawm lub resonance oscillations ntawm cov txuas hniav, dams, tshuab qhov chaw ua rau lawv ntxov ntxov tsis ua hauj lwm. Txoj kev tshawb no ntawm oscillatory dab, muaj peev xwm mus twv seb tus cwj pwm ntawm tej yam ntuj tso thiab kev chaw nyob rau hauv thiaj li yuav tiv thaiv lawv kev puas tsuaj los yog tawm hauv kev khiav hauj lwm lub xeev - lub ntsiab hauj lwm ntawm ntau yam xws li tshuab daim ntaub ntawv, thiab kev soj ntsuam ntawm muaj chaw thiab kev co mechanism - ib tug yuav tsum tau keeb ntawm txij nkawm.
