Ozungulira pafupipafupi - Kodi ndi mmene?

M'dzikoli ife, pali zochitika zambiri ndi njira, amene ali, ndi lalikulu, yosawoneka, osati chifukwa kulibe, koma chifukwa ife chabe osaganizira iwo. Nthawi zonse mwambowu ndipo ali yemweyo zosaoneka ndi yofunika akamanena za zinthu, popanda zimene moyo wathu ndipo N'zovuta kulingalira. Aliyense Mwachitsanzo, amadziwika kuti fluctuation amenewa: mu mau - kupatuka pa boma mgwirizano. Chabwino, kunsonga ya Ostankino nsanja atatsamira pa TH 5, kenako chiyani? Ndipo ikamauma? Palibe ngati uyu kuyamba kubwerera, alowe mgwirizano ndipo angapatutsidwe zosiyana, ndi zina zotero muyaya, bola udzakhalapo. Tandiuza zambiri za anthu amene anaonapo izi kusinthasintha aakulu kwambiri ngati nyumba yaikulu? Aliyense akudziwa zimasiyanasiyana, apa, pali pano, kumeneko, usana ndi usiku, dzinja ndi chilimwe, koma mwanjira ... zambiri. The zifukwa ndondomeko oscillatory - nkhani ina, koma kupezeka ake ndi - lingaliro limodzi zinthu zonse.

Mitandadza padziko lonse: nyumba, pendulum koloko, masamba mitengo, zingwe zeze, pamwamba pa nyanja, miyendo foloko ya ... Pakati kusinthasintha kusiyanitsa wachisokonezo amene alibe repeatability wosamalitsa, ndipo ozungulira, amene nthawi ndi T zokhala thupi akudutsa akonzedwa zonse yake chimasintha, ndiyeno mkombero ndi chimodzimodzi, ambiri olankhula, mpaka kalekale. Childs, kusintha amenewa akutanthauzanji ndi jambulani yotsatana a ndondomeko okhudza malo, monga Tingaone mu oscillations wa pendulum, kapena nsanja chomwecho.

chiwerengero cha oscillations pa nthawi wagawo amatchedwa pafupipafupi F = 1 / T. Pafupipafupi muyeso wagawo - Hz = 1 / s. Zikuonekeratu kuti pafupipafupi ozungulira ndi chizindikiro cha dzina chomwecho mukukayikira a mtundu uliwonse. Komabe, mu kuchita, kuti analandira lingaliro ili, ndi zina zowonjezera ikukhudzana makamaka chikhalidwe rotational ya kusinthasintha kwa. Izo zinachitika pa luso kuti kayendedwe rotational ndi maziko ambiri a makina, zipangizo zamakono. Pakuti mkombero wina wa oscillation wa Poyankha wina, ndiyeno yabwino kwambiri yogwiritsa ntchito okhota kusamutsidwa magawo. Choncho, kayendedwe rotational anayeza mayunitsi okhota, i.e. Kukwera limodzi ndi wofanana 2π radians, ndi ozungulira pafupipafupi ῳ = 2π / T. Kuyambira m'ma mawu osonyeza mosavuta akuoneka kulankhulana pafupipafupi F: ῳ = 2πF. Izi zimathandiza kunena kuti ozungulira pafupipafupi - chiwerengero cha oscillations (ankasinthana zonse) pa masekondi 2π.

Zingaoneke, si mu mphumi, kotero ... Osati kwenikweni. 2π kuchulukitsa ndi 2πF ntchito zamagetsi ambiri maikwezhoni, sayansi masamu ndi ongolankhula zigawo kumene njira oscillatory ndi kuphunzira kugwiritsa ntchito mfundo pafupipafupi ozungulira. Dongosolo la pafupipafupi kumveka Mwachitsanzo, yafupika ndi zinthu ziwiri. Pankhani ya ntchito mu mawerengedwe wagawo "Vol. / Dec" okhota, ozungulira pafupipafupi ῳ numerically chikugwirizana ndi kufunika pafupipafupi F.

Kusinthasintha, monga chofunikira ndi mawonekedwe a kuli kanthu, ndi umunthu wake weniweni - nzika za mkhalidwe wathu ndi zofunika kwambiri mu moyo wa munthu. Kudziwa malamulo a Phokoso n'zotheka kulenga zamagetsi zapamwamba, zamagetsi, ambiri makina amakono. Mwatsoka, kusinthasintha si nthawi zonse kubweretsa ubwino, nthawizina iwo ndikubweretsa chisoni ndi chiwonongeko. oscillations sanaoneke chifukwa cha ngozi zambiri, kuchititsa ukalamba msanga kwa zipangizo, ndi pafupipafupi okhota wa kumveka oscillations wa milatho madamu, mbali makina amachititsa cholephera msanga. Kuphunzira njira oscillatory, luso kulosera za makhalidwe a maofesi zachilengedwe ndi luso pofuna kupewa chiwonongeko kapena kutuluka opaleshoni boma - ntchito yaikulu ya ntchito zosiyanasiyana injini, ndipo anayendera maofesi mafakitale ndi limagwirira kugwedera - chinthu chofunika kwa yokonza.
