Mumakore achangopfuura, zvipingamupinyi zvinonzwika zvakakwevera ngwariro yakawanda zvikuru.Nzvimbo dzakawanda dzakadai semigwagwa mikuru, njanji uye viaducts zvakaiswa zvine zvipingamupinyi zvinonzwika.chinodzivirira inzwi chinoderedza sei ruzha?Nhasi ngatidzidzei pamwe chete.
Kana ruzha rwuri kupararira mumhepo rwasangana neruzhowa chipingamupinyi, rinoburitsa kuratidza, kutapurirana uye kusiyanisa.Chimwe chikamu chayo chinoyambuka pamusoro pechivharo chezwi uye chinosiyana kune imwe nzvimbo yekugamuchira inzwi;Vamwe vanopinda muvharidziro yeruzha kuti vasvike pakugamuchira inzwi, uye vamwe vanoratidzira pamadziro eruzha.
Kurasika kwekupinza kwechivharidzo cheruzha kunonyanya kuenderana nekugovewa kwesimba reinzwi renzwi rinoburitswa neruzha rwuri munzira nhatu.Basa rekuvharira ruzha kuvharira kupararira kweruzha rwakananga, kupatsanura ruzha rwunofambiswa, uye kuita kuti diffraction inzwike yakadzikira zvakakwana.Kana ruzha ruchirova madziro echivharo chinonzwika, diffraction ichaitika kumucheto kwechivharo chinonzwika, uye "nzvimbo yemumvuri inonzwika" ichaumbwa kuseri kwechivharo.Mhedzisiro yekudzikisa ruzha rwechivharo chinonzwika chatinotarisira chiri mukati me "sound shadow area".
Kuenzaniswa nenharaunda yemumvuri wechiedza, nokuti wavelength yewave wave yakareba kupfuura yechiedza chechiedza, muganhu weiyi "sound shadow area" haisi pachena.Rudzi rwekuti ruzha runobva kune ruzha runogona kusvika zvakananga kupfuura kumucheto kwechivharo inonzi "nzvimbo inopenya".Kune zvakare diki "nzvimbo yekuchinja" kubva munzvimbo inopenya kuenda kune inonzwika uye mumvuri nzvimbo.Ruzha rwenzvimbo mu "sound shadow area" yakadzikira pane iyo isina chinovharira mutsindo, inova ndiyo musimboti wekudzikisa ruzha rwekuvharisa inzwi.
Kambani yedu ibhizinesi rekugadzira rinobatanidza dhizaini, kugadzira uye kuisirwa zvipingaidzo zvinonzwika, zviri muAnping, Hebei, China.Parizvino, zvigadzirwa zvedu zvakatengeswa kunyika dzakasiyana.Welcome to taura nesu kuti uwane rumwe ruzivo.E-mail:[email protected]
