Imvamisa ye-Cyclic - kanjani nokuthi kanjani?

Ezweni elisizungezile, kunezimo eziningi nezinqubo eziningi, ezingabonakali, hhayi ngenxa yokuthi azikho, kodwa ngoba asiziboni. Zihlale zikhona futhi ziyizinto ezingenakuqhathaniswa nokuzibophezela kwezinto, ngaphandle kokuthi ukuphila kwethu kunzima ukucabanga ngakho. Wonke umuntu, ngokwesibonelo, uyazi ukuthi ukuchithwa okunjalo: kwifomu evamile kakhulu ukuphambuka kusuka esimweni sokulingana. Hhayi, kahle, phezulu kwe-Ostankino umbhoshongo uye wahamba waya kumamitha angu-5, futhi yini elandelayo? Ngakho lizoqhwaba? Ayikho into enjalo, izoqala ukubuyela emuva, isule isimo somlinganiso futhi izokwehluka kolunye uhlangothi, ngakho-ke kuze kube phakade, uma nje ikhona. Kodwa ngitshele, ingabe abantu abaningi babona ngempela ukushintsha kwezinto ezinkulu kangaka? Wonke umuntu uyazi, uyaqinela, lapha-lapha, lapha-lapho, nobusuku nobusuku, ebusika nasehlobo, kodwa ngandlela-thile ... angabonakali. Izimbangela ze-oscillatory inqubo yinye indaba, kodwa ukutholakala kwayo kuyisignali engenakuhlukaniswa nayo yonke into.

Konke kunyakaziswa nxazonke: izakhiwo, izakhiwo, ama-pendulum of the clock, amaqabunga emithini, izintambo ze-violin, ubuso bomkhumbi, imilenze yefoloji yokugubha ... Phakathi kokukhipha kunezinto eziyingozi ezingenakho ukuphindaphinda okuqinile, kanye nezindlela ezihamba phambili, lapho okwesikhathi esithile umzimba okhukhumezayo udlula isethi Izinguquko, bese lo mjikelezo uphinda ngokuqondile, ngokujwayelekile, isikhathi eside. Ngokuvamile, lezi zinguquko zihilela ukusesha okulandelanayo kwezixhumanisi zendawo, njengoba kungabonwa uma kuqhathaniswa ne-pendulum noma umbhoshongo ofanayo.

Inombolo yokuchithwa kwesikhathi ngasinye iyabizwa ngokuthi imvamisa F = 1 / T. Isilinganiso sokulinganisa imvamisa - Hz = 1 / sec. Kuyacaca ukuthi imvamisa ye-cyclic iyi-parameter ye-oscillations efanayo yanoma yiluphi uhlobo. Noma kunjalo, ngokusebenza, lo mbono, ngezinye izithako, kuthiwa ngokuyinhloko ukushintshashintsha kwemvelo yokujikeleza. Kwenzeke kwezobuchwepheshe ukuthi ukunyakaza kokujikeleza kuyisisekelo semishini eminingi, izindlela, amadivaysi. Ngenxa yokunyuka okunjalo, umjikelezo oyedwa inguquko eyodwa, futhi kulula kakhulu ukusebenzisa imingcele yokuhamba nge-angular. Ukuqhubekela phambili kulokhu, ukufuduka kokujikeleza kubalwa ngamayunithi angular, e.g. Enye inguquko ngama-radiens angu-2, kanti imvamisa ye-cyclic yi-ῳ = 2π / T. Lobudlelwane bukhombisa kalula uxhumano nemvamisa F: ῳ = 2πF. Lokhu kusenza sikwazi ukuthi imvamisa ye-cyclic iyinani lezinkomba (ukuguqulwa okugcwele) kumasekhondi angu-2π.

Kungabonakala, hhayi ebunzini, kanjalo ... Hhayi ncamashi. Izici 2π no 2πF zisetshenziselwa ukulinganisa okuningi kwe-elekthronikhi, i-mathmatical and theory physics kwizigaba lapho kusetshenzwa khona izinqubo ze-oscillatory ngokusebenzisa umqondo wemvamisa ye-cyclic. Ifomula yemvamisa ye-resonant, isibonelo, incishiswe yizici ezimbili. Endabeni yokusebenzisa i-unit "rev / sec" ekubalweni, i-angular, i-cyclic, imvamisa ῳ ihamba ngokuhambisana nenani lemvamisa F.

Ukuqothulwa, njengento esemqoka kanye nesimo sobukhona bezindaba, nokubonakala kwayo okubonakalayo - izinto zobuntu bethu, zibaluleke kakhulu empilweni yomuntu. Ukwaziswa kwemithetho yokukhishwa kwe-oscillation kuvumela ukudalwa kwamakhompiyutha anamuhla, ubuchwepheshe kagesi, imishini eminingi yanamuhla. Ngeshwa, ukuguquguquka akusho ngaso sonke isikhathi umphumela omuhle, ngezinye izikhathi kubangela usizi nokubhujiswa. Ukungaguquki kokuguquguquka, imbangela yezingozi eziningi, kubangela ukuguga okungakapheli kwemishini, kanye nemvamisa ye-cyclic yokudumala kwamabhuloho, amadamu, izingxenye zemishini iholela ekuhlulekeni ngaphambi kwesikhathi. Ukutadisha izinqubo ze-oscillatory, ikhono lokubikezela ukuziphatha kwemvelo yemvelo kanye nezobuchwepheshe ukuze kuvinjelwe ukubhujiswa noma ukuphuma kulo msebenzi osebenzayo ngumsebenzi oyinhloko wezicelo eziningi zobunjiniyela, futhi ukuhlolwa kwezakhiwo zezimboni kanye nezinqubo zokumelana nokucindezeleka kuyinto ebalulekile yokugcinwa.
