Yintoni ikhilomitha elwandle yaye yintoni na ngeqhina lomtshato?

Xa iincwadi ngohambo kunye adventures, iifilimu malunga omkhulu lithemba, amanqaku kwi sihloko kunye nencoko ngokwezelizwe phakathi oomatiloshe badla slips elithi "imayela Nautical". Lixesha phambili uku bana phandle Nomlinganiso ubude wokuthumela, Noomateloshe kutheni ungasebenzisi iikhilomitha zethu njengesiqhelo.

Yintoni 1 imayili Nautical?

Ekuqaleni, eli xabiso ingqamana ubude 1/60 a degree of isangqa phezu komhlaba kunye kwiziko coinciding kunye embindini planethi. Ngamanye amazwi, xa siqwalasela nayiphi okuyi, iimayile Nautical yi malunga lilingane ubude umzuzu omnye anenkululeko. Ngenxa yokuba umhlaba eyahlukileyo kancinane ukusuka imilo ibhola efanelekileyo, ubude 1 minute isidanga Meridian zihlolisisiwe zinokwahluka thile, ngokuxhomekeke inkululeko. Uninzi banga izibonda - 1861,6 m, kwaye liphantsi kwi-ikhweyitha -. 1842,9 m Ukuphepha ukubhideka, oko kucetywa ukuba ukudibanisa ubude neekhilomitha Nautical. Isiseko lamkele ubude lomzuzu 1 45º izidanga yesibanzi (1852.2 meters). Loo nkcazelo iye yakhokelela ekubeni yintoni eye yenzeka iikhilomitha Nautical Kulula ukubala imisebenzi navigation. Umzekelo, ukuba ufuna kwimephu ukulinganisa umgama oziikhilomitha ezingama-20, ngoko oku kuya kuba ngokwaneleyo ukulinganisa arc imizuzu yekhampasi 20 nakweyiphi na okuyi, imephu.

Ukususela ngo-1954, eUnited States baqalisa ukusebenzisa imayile ngamazwe Nautical (1852 meters). umkhuba wakhe ukholisa llirhangqwa leemitha 1800. Ukubiza esemthethweni kule yunithi sele akamkelwanga. Maxa wambi kukho ukuncitshiswa «nmi», «NM» okanye «NM». Hi ndlela leyi, «NM» yi isiqu oqhelekileyo a nanometer. 1/10 imayili ngamazwe Nautical = 1 = 185.2 iimitha ubude intambo. A ikhilomitha 3-zaselwandle ngokulinganayo 1 league. Kwi-UK, ngoko wayedla imayile yakhe elwandle ulingana leemitha 1853,184. Ngowe-1929, e Monaco, kwingqungquthela yamazwe ngamazwe enikelwe ezahlukeneyo imiba hydrography, apho ubude imayile Nautical kuchaziwe mitha 1852,00. Musa ukulibala ukuba Mile asinto nje zaselwandle kodwa umhlaba. Kulo mzekelo, ubude bawo amaxesha 1.151 ngaphantsi kwe elwandle.

Buyintoni ubudlelwane phakathi kolwandle iikhilomitha kunye udumbo?

Mile Marine (iimayile ezisetyenziswa elwandle) okanye njengoko ngamanye amaxesha kuthiwa, ngokwezelizwe okanye inqanawa, lisetyenziswa kwiJografi, eyama kunye navigation. Ekubeni buhlobene ingqikelelo ibandla marine esetyenziswa kwishishini eenqanawa njengeyunithi esisiseko Velocity. Enye unit ilingana imayile enye ngeyure walihamba isitya. Igama "elisisiseko" ngenxa yokuba, kumaxesha amandulo iinqanawa esetyenziselwa umlinganiselo Velocity ukubambezeleka. Yaba log okanye ibhodi kwi imilo unxantathu, apho iqhotyoshelwe umthwalo. Ezo drogue baba eqhotyoshelweyo lin (intambo), nto leyo nge kumgama othile ibotshelelwe iindawo. Lag silahlwe emanzini, ngoko kangangexesha elikhethiweyo sexesha (ukusuka imizuzwana 15 ukuya umzuzu 1) lwabalelwa abe ziindawo ekudityanwa ashiye amanzi.

Kukho iinguqulelo ezahlukileyo malunga umgama phakathi ezalathelwe uphuhliso. Abanye bakholelwa ukuba iinyawo-25 (7.62 m), kwaye ukuba imizuzwana 15 akwasala node mnye, isiphumo kwathengwa, imayile enye Nautical (100 ft / min). Ngokutsho uguqulelo yesibini, amaqhina ibotshelelwe umgodi 47 intshi 3 (14.4018 m), kunye ubalo yaba imizuzwana 28. Kulo mzekelo, iyunithi enye ebonisa izinga 101,25 iinyawo / min.

Ngethemba ngoku ungazange nzima ekuqondeni isigama eselwandle, kunye iikhilomitha ukusuka kwiindawo ziya kuba ebengezela kwiikhilomitha njengesiqhelo.
