Frequency Zijika - ntoni njani?

Kwihlabathi elisingqongileyo, kukho zizinto ezininzi iinkqubo, izinto ezo, ngokubanzi, ongenakubonakala, hayi kuba khona, kodwa ngenxa yokuba nje musa baziphawule. Basoloko akhoyo kwaye umongo ongabonakaliyo ebalulekileyo enye yezinto, ngaphandle apho ubomi bethu kwaye Kunzima ukucinga. Nganye, umzekelo, kuyaziwa ukuba kumahlandinyuka ezinjalo: ngokwemiqathango jikelele - ukutenxa kwindlela esisetyenziswe ngayo lizama karhulumente. Kaloku, incam nenqaba Ostankino wacinezela th lwabo 5, uze emva koko yintoni? Kwaye lukhuni? Ayikho into efana oku kuza kuqalisa ukuba babuyele, isiliphu sizinze kwaye ziya baphambuke kwelinye icala, njalo ngonaphakade, njengoko elide njengoko kuya khona. Ndithi mna, abantu abaninzi ombonileyo ezi ukuhla kakhulu kakhulu izakhiwo omkhulu kangaka? Wonke umntu uyazi buyahluka, apha, apho, apha, apho, imini nobusuku, ihlobo nobusika, kodwa ngandlel '... hayi kakhulu. Izizathu inkqubo oscillatory - yenye into, kodwa ubukho kwalo - lophawu engenakususwa izinto zonke.

Umfuno ngeenxa zonke: izakhiwo, clock pendulum, amahlamvu emithini, imitya ivayolin, umphezulu wolwandle, imilenze enefolokhwe ... Phakathi ukuhla bahlule umbhodamo azinayo repeatability engqongqo, kwaye elibujikele, ngubani kangangexesha i T jinga umzimba ipasisa isethi epheleleyo yayo itshintsha, yaye ke umjikelo ifana nqwa nale, ethetha ngokubanzi, ngonaphakade. Ngokuqhelekileyo, ezi nguqu kubonisa ukuba scan ezilandelelana ngayo zilungelelanise lwendawo, njengoko kunokubonwa kwi oscillations ze kuqala, okanye nenqaba efanayo.

Inani oscillations nganye ixesha iyunithi ibizwa amaza F = 1 / T. Frequency unit womlinganiselo - Hz = 1 / s. Kucacile ukuba amaza elibujikele i parameter yegama elifanayo kokuthandabuza naluphi na uhlobo. Noko ke, xa kusenziwa oku, wavuma le ngcamango, ezinye izongezelelo zinxulumene ikakhulu uhlobo ojikelezayo le ukuhla. Kwenzeka kwimizobo ukuba nentshukumo ejikelezayo sisiseko wesininzi oomatshini, izixhobo, izixhobo. Kuba kumjikelo oscillation Ukusikwa enye, ngoko ke lula kakhulu ukuba ukusebenzisa i parameters nokususwa emboxo. Ngako oko, le nentshukumo ejikelezayo walinganisa iiyunithi emboxo, ngamanye revolution omnye ulingana 2π kwilayini eziqala embindini, kwaye rhoqo ῳ elibujikele = 2π / T. Ukusuka eli binzana c na obala zonxibelelwano frequency F: ῳ = 2πF. Oku kwenza kube lula ukuba bathi amaza elibujikele - inani oscillations (igophe elipheleleyo) ngaphezu kwemizuzwana 2π.

Kubonakala, ukuba ayikho ebunzi, ngoko ... Hayi ngokwenene. 2π multipliers kunye 2πF ezisetyenziswa quadratic ezininzi elektroniki, physics zemathematika kunye nemiqathango kula macandelo apho iinkqubo oscillatory zihlolisiswe kusetyenziswa ingqikelelo frequency elibujikele. Ifomula yobuninzi livakale, umzekelo, njalo kuncitshiswa izinto ezimbini. Kwimeko ukusetyenziswa kwiyunithi ukubala "vol. / Sec" emboxo, rhoqo elibujikele ῳ ngamanani ingqamana ixabiso amaza F.

Ukuhla, njengoko umongo kunye uhlobo lwe ubukho mba, kwaye uphila real - izifundo bethu zibaluleke kakhulu ebomini bomntu. Ulwazi kwemithetho intlokoma enokwenzeka ukudala elektroniki phambili, ubunjineli yombane, uninzi zoomatshini banamhlanje. Ngelishwa, ukungalingani musa asoloko nemiphumo emihle, ngamanye bazise neenzingo intshabalalo. oscillations Shicilela kubangela iingozi ezininzi, ibangela kwesikhumba zonke izinto, kwaye rhoqo emboxo le oscillations livakale of iibhulorho, amadami, izahlulo umatshini ebangela ukungaphumeleli kwabo kwexesha. Uphononongo kweenkqubo oscillatory, ukukwazi ukuqikelela ukuziphatha kwezibonelelo zendalo kunye nobugcisa ukuze kuthintelwe kumonakalisa okanye uphume imo yokusebenza - kowona msebenzi izicelo ezininzi zobunjineli, kunye nokuhlolwa kweendawo zoshishino kunye nendlela kokukona - into efunekayo yesondlo.
