Tautau Whakahaere - auau o oscillation

He ariā tinana pai-mohiotia tawhā o ngā tukanga oscillatory - te kaha tīwera, me te wā. Ko te kupu, i raro i wiri ite ture wā maha e tukurua i te tukanga o te huri i te inenga ā-huri noa tona uara toharite ranei kore. A mana'o na tatou e kua he huru sinusoidal tenei ture. Na, ki te hoatu te mahi F (x) o te tukanga e te momo F (x) = K * hara (x), to tatou noa te taua mahi kōpiupiu, e, mahara, ki runga, me te iho, ki runga, me te heke iho ...

A feruri i te kauwhata o mea mahi o te, i roto i te parau tumu, i tetahi uara i runga i te tuaka Y denoted Y1, a neke haere te tuaka X, y2 kitea te wāhi i muri ki te uara o te Y1. Na, ki te mea te-tuaka X, i te v2 pūwāhi, kei whakaroa āputa rite ki T = (y2 - Y1), whiwhi tatou i te w3 wāhi, a ka waiho i te reira rite ki te Y1 me y2. Ko te āhua o te kauwhata i waenganui i enei ngā rite toutou runga wāhanga o muri katoa rite T. Ko te kupu kua kitea e matou he T tawhā mo te tukanga whakaahuatia e te tātai F (x) = K * hara (x), e kua te taonga faahiahia e taui i roto i te tautohe X T mata ki te huringa i roto i te mahi F (x) i runga i te whānuitanga katoa o ona uara. No te mea huringa i roto i te tuaka-X he mutunga i te wa, i roto i te kupu atu, te maha o ngā huringa T ore tokomaha, tatou i te huritaiāwhio, arā faahiti ahau, huringa o te mahi. i huaina wā Cycle T te te wā o te oscillation me te whanganga i roto i hēkona. Otiia ake whakaaetia i roto i te toi ki te whakamahi i wae inenga, e kiia nei ko te auau oscillation, denoted f me computes f = 1 / T, he kōwae huaina ko reira Hertz (Hz). Auautanga o 1 Hz - he kotahi oscillation ia te rua.

E karapotia matou e ao "wiri". Rerekē - tangi te reira, he nāianei hiko i roto i te waea, wiri tikanga, te marama, te tai, te huringa o te aorangi, me ... e kore tatau ratou ki roto ki, enei wiri. E katoa o ratou rohe tikanga nui o ratou auau, e mea "he whānuitanga o te rerekētanga." Hei tauira, te auau oscillation o paraparau tangata iarere reo - i 16 Hz ki te 20 kHz (1 kHz = 1000 Hz), me te whānuitanga o ngā aratuku tangi colloquially takoto i roto i te whānuitanga 100 - 4000 Hz. He meka pai mohiotia e rongo kore te iwi katoa te whānuitanga katoa o oro - maha kē 12-15 kHz reo Hurai. Ka pā te tikanga te wiri ultrasonic 100, 200 kHz me runga ake. kia hoki kapewhiti kōrero tikanga i roto i te whānuitanga nui o iarere - a faaite Hz me tekau o kHz. Otiia whai te nuinga te whānui o ngaru hiko ngā - i hea, me te ake ki nga mano maha o mirioni o Hz. I roto i tenei tūāwhiorangi o ngaru marama o te whenua ao he iti rawa, engari e mohio a ratou i to tatou whēkau o kite. Rerekē auau oscillation i te tūāwhiorangi o ngaru marama whakatau te tae o te marama kitea - i whero ki papura.

Otiia hoki ki "tetahi tapawha." Tino maha, he reira watea ki te whakamahi i te wae paku whakarerekētia. Taua artifice taea ki te faaohie tokomaha o nga tātai, ka meinga ratou kitea atu. A he tika ki te meka e te mahi oscillation sinusoidal kōrero te taea ki te whakamahi i ngā taurangi i roto i te wae o te inenga o koki tenei - tātoro nekehanga ranei. Otiia i te wa ano, i roto i te tātaitanga o te "ngokingoki" tamau 2p, e, tahi ki kitea te auautanga i roto i maha kīanga pāngarau. Na ka whakaritea e ratou ki te whakauru i te kōwae whakarerekētia o auau inenga, a hoatu ana ki te ingoa "auau oscillation huringa." Ko te ngako o tenei kōwae ko e takoto tona auau te hoki te maha o oscillations i roto i te 2 hēkona π *, i.e. 6.28 hēk. tātai auau huringa e te tātai ω = 2 * π * f. No ki te auautanga huringa whakahuatia e tona wae o te inenga - tātoro ia te rua.

He tonu pūnaha kōpiupiu etahi tawhā e tohu tona tuakiri. Tangohia to tatou tāwēwē tawhito pai, me te paku nui, whakaiti i te reira ki te āhua o te tukanga wiri - tohu-tock, tohua-tock. Ki te mahi i tenei kotahi he nui ki te pana i te reira, a ... mahue anake. Aha e kite tatou? oscillates roa nui, kahore tetahi atu tono o kaha, e kore e tona auau oscillation huri te tautau, a ka heke te āta te kaha tīwera, no te mea o ope waku i roto i te whakaaro tūturu. Taua rerekē ka arawhiti i muri i takoto te pana o te kaupapa tautau, tetahi atu pūnaha wiri ranei kei te anake i te tawhā, ka karanga ake. Ki te amo tatou e he rite ki te kore i te wa taua tu ope, a ko reira tino māmā - katoa i roto i to tatou ringa, he tautau taua, huaina te mea te pāngarau, ka oscillate ake, a taea te tātai te wā oscillation i te mohiotia, kua nei kua riro i te aronui, te tātai - C = 2 * π * √ l / g.

Mai i te tātaritanga he mea taea ki te hanga i te mutunga nui: te auau tūturu o oscillation o te tāwēwē e anake whakaritea e te tawhā ā o te pūnaha - te roa miro me te nui o te whakaterenga o te mahara o te whenua.
