Zodziwitsa ntchito: Zikhulupiriro ambiri

Nthawi zambiri mu phunziro la zochitika zachilengedwe, mankhwala ndi thupi katundu zinthu zosiyanasiyana, komanso kuthetsa mavuto zovuta luso anakumana ndi njira, mbali ya chizindikiro ndi pafupipafupi, ndiye pali chizolowezi kubwereza patapita nthawi zina za nthawi. Pakuti kufotokoza ndi chifaniziro mwatsatanetsatane za cyclicality ngati sayansi, pali mtundu wapadera wa ntchito - ntchito nthawi.

Chophweka kwambiri komanso kumvetsa aliyense chitsanzo - mankhwala a dziko lathuli kuzungulira Sun, imene nthawi zonse kusintha mtunda pakati pa iwo umamumvera mkombero yapachaka. Mofananamo, akubwerera ku mpando wake, atacita kukhota wathunthu, tsamba chopangira mphamvu. Zonsezi zimachititsa tinganene kuti ndi phindu masamu ngati ntchito yake nthawi. Ndi lalikulu, dziko lathuli cyclical. Ndipo izo zikutanthauza kuti ntchito nthawi zimatengera kwambiri pa chimango anthu.

Kufunika masamu mu chiphunzitso chiwerengero, mtunda, masiyanidwe maikwezhoni , ndi kuwerengetsera yeniyeni geometrical zinachititsa kuti zikamera m'zaka za m'ma chakhumi ndi chisanu ndi chinayi, latsopano gulu ntchito ndi katundu zachilendo. Iwo anali ntchito nthawi kutenga mfundo zofanana pa mfundo zina chifukwa cha kusinthika zovuta. Tsopano ntchito m'madera ambiri a masamu ndi maphunziro ena a sayansi. Mwachitsanzo, mu kuphunzira zotsatira za vibrational yoweyula sayansi zosiyanasiyana.

Mu osiyanasiyana mabuku masamu ndi matanthauzo osiyanasiyana ntchito ndi nthawi. Komabe, mosasamala kanthu za kusiyana mu mawu, iwo ali ofanana, popeza pofotokoza chomwecho zimatha kugwira ntchito. Losavuta ndi odziwika mwina tanthauzo zotsatirazi. Ntchito, ndi ndalama zimene ziri sasintha, ngati ife kuwonjezera mfundo zawo zingapo ena kuposa ziro, otchedwa nthawi kugwira ntchito amaimira kalata T amatchedwa nthawi. Kodi zonse izi zikutanthauza kuchita?

Mwachitsanzo, ntchito yosavuta mawonekedwe: Y = f (x) adzakhala nthawi ngati X ali ndi phindu zina nyengo (T). Tanthauzo ili ndizoonekeratu kuti ngati mtengo n'zosangalatsa kumva za ntchito yake ndi nthawi (T) akufotokozera mfundo imodzi (x), ndiye kufunika kwake komanso adzakhala wodziwika pa × T + × - T. Mfundo zofunika pano pamene T ndi ziro adziika ntchito dzina. ntchito nthawi atha chiwerengero wopandamalire wa panyengo zosiyanasiyana. Mu zambiri za milandu zabwino mwa mfundo za T kotani pakati pa ophunzira chipitirire chizindikiro kuthungo. Njirayi imatchedwa nthawi ofunika. Ndi makhalidwe ena onse T nthawi zonse divisible. Izi wina chidwi ndi ofunika kwambiri kwa minda osiyana katundu.

Sankhani ntchito nthawi alinso mbali zingapo. Mwachitsanzo, ngati T ndi nthawi yaikulu ya mawu akuti: Y = f (x), ndiye akufuna nchito imeneyi, basi zokwanira kumanga nthambi mu imodzi mwa nthawi za nthawi yaitali, ndi pite pamodzi ndi × olamulira pa mfundo zotsatirazi: ± T, ± 2T , ± 3T ndi zina zotero. Pomaliza, tisaiwale kuti si onse kugwira ntchito nthawi ndi nthawi yaikulu. Chitsanzo chachikulu tingachipeze powerenga za izi German masamu Dirichlet ntchito ya mtundu zotsatirazi: Y = D (x).
