Thaum lub cev oscillates nrog nws tus kheej zaus nrog kev pab los ntawm ib lub sij hawm sab nraud uas nws zaus sib npaug rau qhov zaus ntawm lub cev, oscillations ntawm lub cev hu ua resonant oscillations.
Resonant vibration yog dab tsi?
Ib vibration resonance tshwm sim thaum cov khoom siv lossis cov khoom raug cuam tshuam rau sab nraud quab yuam kev vibration tshwm sim ntawm ib lossis ntau dua ntawm nws lub ntuj frequencies Cov khoom lag luam teb vibration yog amplified thiab tuaj yeem ua tau loj! Kev vibration resonance tuaj yeem ua rau cov khoom puas tsuaj loj thiab ua rau lawv lub neej luv.
Thaum lub cev vibrates nyob rau hauv ib lub sij hawm quab yuam lub vibrations ntawm lub cev?
Qhia: Cov kev vibrations ntawm lub cev uas tshwm sim nyob rau hauv kev cuam tshuam ntawm sab nraud lub sij hawm quab yuam ua rau nws yog hu ua lub quab yuam vibrations.
Yuav ua li cas thaum lub kaw lus vibrating mus txog resonance?
Qhov no yog ib qho piv txwv ntawm resonance - thaum ib yam khoom vibrating ntawm tib lub ntuj zaus ntawm ib tug thib ob khoom quab yuam uas ob yam khoom mus rau hauv vibrational motion. Qhov tshwm sim ntawm resonance yog ib txwm muaj kev vibration lojTxawm hais tias lub zog vibrating, yog tias resonance tshwm sim, qhov tshwm sim loj heev.
txhais li cas los ntawm kev vibration ntawm lub cev?
Kev vibration, ncua sij hawm rov qab mus rau lub sijhawm ntawm cov khoom ntawm lub cev elastic lossis nruab nrab, feem ntau tshwm sim thaum yuav luag txhua lub cev lub cev tau hloov pauv los ntawm nws qhov kev sib npaugthiab tso cai rau teb rau cov rog uas zoo li rov ua kom muaj kev sib npaug. …
