Namuhla, izifiki eziningi ezintsha, efulethini kwanikeza, baphoqwa ukuba enze umsebenzi ezengeziwe, kuhlanganise ukwahlukanisa of emakhaya abo ngenxa izinto esezingeni esetshenziswa ukuvumela ingxenye kuphela ukufihla ukuthi kwenzekani emzini wakho siqu, futhi akanandaba bobulili nentando omakhelwane babo.
Ngezinye ijubane umsindo e ukudla okuqinile kuthinta okungenani kwabantu futhi kuyaqina indaba, ukuze kunqandwe. Ngakho-ke, ngo-imishini isikhala ungqimba eduze odongeni emvula wenza umakhalekhukhwini ne "Kunokuhlobana" ngaphansi nangaphezulu. It ikuvumela ukunciphisa kunomsindo e-decibel angu-, ngezinye izikhathi ezingaphezu kuka-10. Khona-ke wabeka basalt amacansi, futhi phezu - amabhodi Gypsum, ezembula umsindo kwangaphandle kusukela efulethini. Lapho igagasi umsindo "izimpukane" ilungiselelo ezinjalo, zize izingqimba yisivikelo ukuthi kukhona ukungena nakwamanye amazwe futhi ezithambile. Uma umsindo has butho elikhulu, izinto ukukuqonda, ungakwazi ngisho nokushisa up.
Nokunwebeka unesimo esifana, njengamanzi, ukhuni, metal, ukudlulisa kahle amaza omsindo, ngakho sizwa "ukucula" emangalisayo zezinsimbi zomculo. Abanye abantu esikhathini esidlule ukunquma indlela, isibonelo, nabagibeli, ngokubeka indlebe yakhe emhlabathini, okuyilona elisebenzayo futhi ngokwanele nokunwebeka.
Ijubane womsindo km kuncike izici imvelo lapho ubabonisa. Ikakhulukazi, inqubo kungathinta umfutho walo, amakhemikhali ukwakheka, izinga lokushisa, umswakama, ukuminyana kanye neminye imingcele. Ngokwesibonelo, steel ishidi sihamba amaza omsindo ngesivinini 5100 amamitha ngomzuzwana, ingilazi - mayelana 5000 m / s, futhi egwadle esihlahleni - mayelana 4000 m / s. Ukuze udlulisele nesivinini amakhilomitha ngehora kumele kube andisa Izibalo 3600 (imizuzwana ngehora) futhi hlukanisa imali yazo ngo-1000 (amamitha ikhilomitha ngalinye).
Ijubane womsindo km i osebenzelana aqueous ihlukile izinto nge salinities ezahlukene. Ukuze amanzi ahlanzekile ngesikhathi lokushisa 10 Celsius, kumayelana 1450 m / s no ezingeni lokushisa degrees Celsius futhi ingcindezi efanayo 20 - imayelana 1490 m / s.
Saline imvelo esifanayo ukudluliswa ngokucacile ephakeme ijubane kunyakaza umsindo.
Wokusakazeka umsindo emoyeni futhi lokushisa nasekuthengeni. Uma inani lale ipharamitha uyalingana 20 degrees Celsius, le amaza omsindo ukudlula nge velocity we-340 m / s, okuyinto mayelana 1200 km / ihora. A degrees zero ngesivinini siyehla ukuba 332 m / s. Ukubuyela insulators lwethu amafulethi, singabona ukuthi izinto ezinjalo, ezifana kukakhokho, elivame ukusetshenziswa ukunciphisa izinga umsindo zangaphandle, the velocity womsindo amakhilomitha kuyinto km 1800 kuphela / h (500 metres ngomzuzwana). Lena izikhathi eziyishumi leliphasi kunaleyo ngezici steel ngokuningiliziwe.
Igagasi umsindo kuyinto oscillation longitudinal imvelo lapho ubabonisa. Lapho edlulisa, isibonelo, isiqeshana somculo amashuni ngokusebenzisa isiphi isithiyo, lizinga umthamo yayo kuyehla, ngoba ekushintsheni amplitude oscillation. Imvamisa lamahubo lilingana, ukuze sikwazi ukuzwa Izwi lowesifazane kwabesifazane kanye wesilisa - womfana. Ezithakazelisa kakhulu yindawo lapho ijubane umsindo e km iseduze zero. Lokhu - cleaner lapho lokhu amagagasi uhlobo kuthiwa neze okusakazwa. Ukuze abonise ukuthi kusebenza kanjani lokho, izazi zesayensi wabeka ukushaya alarm clock a hood, okuvela kulo umoya akhishwa. Njengoba kuvamile nokuba ka lomoya, ethulile wezwa ucingo.
