Kodi kutembenuka mainchesi kuti mamilimita? Kodi mm mainchesi ambiri?

Kodi mukukumbukira msungwana wamng'ono kuchokera ku nthano, Thumbelina? Inu nkomwe za chiyambi cha dzina lake? Tiyeni tikambirane.

Za mawu akuti "."

Tamasulira kuchokera ku mawu Dutch "inchi" amatanthauza "chala". Ndi muyeso wa kutalika wofanana ndi M'lifupi mwa anthu chala pafupifupi (ngakhale munthu wanena kuti tikulankhula za kutalika kwa phalanx chapamwamba). Koma, chilichonse gawo kapena funso, likukhalira kuti Thumbelina - mtsikana mtengo likundikanikizira.

Mwa njira, mu epic wosangalatsa wodziwika ngwazi wina wa yofanana. Iwo likukhalira kuti Boy wathu wokondedwa chala akhoza kutchulidwa ndi kufanizira Dyuymovchikom. The nthabwala, kumene. Komabe, zala za anthu osiyana, kotero akadali mukufuna mwachindunji: angati mamilimita pa mamilimita?

Ukulu wa inchi

Kudziwa chimene chimapanga inchi mu mm, si mophweka. chakuti wagawo ichi, chimene kwa mazana a zaka, mobwerezabwereza anasintha ngakhale mwa dongosolo womwewo wa miyeso, osanenapo zosiyanasiyana. Vienna inchi ofanana masentimita 2.6340278 kapena 26,3 mamilimita; Spanish m'dera inchi (pulgada) a 23,2 mamilimita; Mu Mexico, komwe limatchedwanso pulgada, mainchesi mm kukula anali wofanana za 23,3.

Pamndandanda uwu tingathenso kudzaza pafupifupi osawerengeka. Mu lirilonse la Länder German anali osiyana ndi mtundu wina wa kutalika miyeso anati: Baden, Bavaria, Saxony ndi Prussia, komanso inchi Chitaganya cha Rhine. M'zigawo Baltic, motero, anali Courland, Riga ndi Revel. Mu madera wa Commonwealth zinakhala Old Polish ndi mainchesi novopolskie ndi Wrocław, Breslau, Silesia, akale Chilituyaniya. France muyeso wa utali. Panali mayunitsi zofanana ngakhale mu Japan ndi China. Choncho, 1 Kuni (Chinese inchi) mu mamilimita anali 33,3. Palinso otchedwa vidikonovsky inchi, nthawi zambiri amagwiritsidwa ntchito kuyeza digito kamera masanjidwewo. Akhoza 16,93 mm.

Za Convention Meter ndi dongosolo chinkafunika

May 20, 1875 mu Paris, pa Unduna Woona za okhonda la France, yosainidwa T. N. Meter Convention - pangano cholinga kuonetsetsa pachilichonse mu mfundo mayiko metrological. Ndi mgwirizano umenewu, limodzi ndi Russia - m'malo mwa pangano mfumu yosainidwa mlangizi Okunev ofesi ya kazembe. Kukhazikitsidwa kwa msonkhanowo anali kutsogolera zofunika pa chitukuko cha dongosolo chinkafunika ya miyeso ndi chiyambi cha chitukuko cha mita muyezo ndi kilogalamu. Patapita anayambitsa mfundo zofunika pachikhalidwe m'madera a magetsi Optics. Ndi Meter Convention kwa nthawi kuti Ufumuyo mayiko oposa 50 onse, kuphatikizapo otukuka kwambiri.

Ziwiri zofunika kuzipenya. Choyamba inchi - akale wagawo ambiri panalibe ubale dongosolo chinkafunika. Komanso, OIML (Organization mayiko a Malamulo Metrology) mwamphamvu akuonetsa kusiya othamanga wa umakopa kumene komabe ntchito miyezo ya (chifukwa, ine ndikuganiza, ndi bwino). Onani wachiwiri. Yaikulu komanso wotukuka kwambiri dziko United States, ngakhale, ndi anasaina Meter Convention, koma saganizira yokha womangidwa ntchito dongosolo chinkafunika kwa njira. Inchi chimagwiritsidwa ntchito monga unit m'deralo monga onse a mdziko kwambiri kumalepheretsa kutsatira OIML malangizo.

Inchi English

Chotero kodi ndi onse womwewo wagawo ichi mmene tikumvera 1 inchi mu mamilimita? Panopa pa kutchula mawu akuti zambiri amatanthauza English, kapena ufumu muyeso wa utali. Mtengo wake ndi zinasintha mobwerezabwereza, koma ndi 1958 kumasulira mainchesi mamilimita chingandithandize 25,4 pa unit. Kotero kuti kukula kwa makhalidwe athu fairytale chawonetsedwa tsopano mpaka masentimita 2,54. Ndipotu nyenyeswa!

Mwa njira, mu England, inchi otchedwa inchi, izo anazindikira chizindikirocho - ogwidwawo zizindikiro Mwachitsanzo: 17 "Munthuyo anaganiza, nkuti, kugula TV, sayenera kusokonezedwa ndi bala awiri kapena kutchula chiwerengero ndi kanjedza. Screen kukula. Ndi zonse za yemweyo SI mayunitsi.

Mu United States, monga England, ndi 1958 DPI imatengedwa wofanana masentimita 2,54 Pali tinganene ntchito zosiyanasiyana, ndipo ndithu ambiri -. Mwachitsanzo, pamene musankhe ndi likungosonyeza mfuti. Mu America likungosonyeza chida (thunthu mkati mwake) amayezedwa hundredths la inchi. Choncho, wotchuka bulu 45 likungosonyeza chida zikutanthauza ndi thunthu awiri mainchesi 0.45 (11.43 mm).

Kumene ntchito.

Pali funso lovomerezeka. N'chifukwa chiyani munthu wogwira ntchito kudziko lomwe limagwiritsa ntchito dongosolo chinkafunika ya miyeso (Russia), ayenera nkhawa mitengo US kapena kutalika, nkuti, mmene kutembenuza mamilimita mu mainchesi? Koma zinthu siziri mophweka. M'zaka zaposachedwapa, chifukwa patsogolo luso American ndi zikamera wa mawu atsopano luso, mainchesi anayamba kugwiritsidwa ntchito chinenero cha Chirasha kwambiri zambiri. Ndi pamaso panali mafakitale lonse, mmene anati phindu akuti ndi unit yaikulu ya kayesedwe. Choncho, mainchesi zambiri anayeza likungosonyeza zida zankhondo. Komabe, ayenera kumvetsa paokha. Mwachitsanzo, mu UK, mosiyana ndi US, gauges kusonyeza thousandths ochepa la inchi. A Russian wotchuka "trehlineyka" - ndi 3 mayunitsi pamwamba (7.62 mm).

Mainchesi amagwiritsidwa ntchito makampani magalimoto: iwo kuyeza awiri a galimoto gudumu. Popeza kuli makampani Soviet galimoto anayamba ndi luso ena ndi ziphatso, palibe pang'ono ntchito ndi terminology yachilendo. Mwachitsanzo, mmodzi wa makampani loyamba borns zoweta galimoto, PCM-10, yamphamvu m'mimba mwake 2 1/2 "(63.5 mm). The awiri mainchesi amasonyeza zakutali magalasi, ndi wina unit wa muyeso ntchito machubu ankachita.

About inchi chubu

Kodi mwambo yaitali ntchito kuchuluka pa ntchito ndi mapaipi mpweya ndi madzi, komanso kulozera kwa iwo kagawo ulusi. Koma tisaiwale: chitoliro inchi mm - uno sali yemweyo monga inchi wamba.

Mfundo imeneyi sitinganene kuti sayansi, koma ali ndi tanthauzo bwino chimatanthauza. Inchi chubu imatengedwa kuti ndi m'mimba mwake kunja kwa paipi imene awiri mkati limafanana ndi zotalika mwachizolowezi. Ukulu wa izi penapake umasinthasintha: mapaipi ndi thicknesses zosiyanasiyana kumene amakhudza chiŵerengero cha diameters. Koma ena pachilichonse kufika pa nkhani imeneyi.

Pa chiphaso makonzedwe

Ponena za magawo opangidwa (adagulung'undisa) chitoliro zambiri zikutanthauza m'mimba mwake kunja. Kumene, pansi zofanana mfundo kunja koma osiyana khoma makulidwe, miyeso mkati mwa zinthu zosiyanasiyana akhoza kusiyana kwambiri. Choncho, lingaliro la makonzedwe chitoliro kutengerapo: Izi ndi wapadera mkati mwake, zomwe mwina zizigwirizana ndi zina phindu kunja kuno. Mwachitsanzo, mu chitoliro, amene ndimeyi ndi 40 mm, leni awiri mkati akhoza kukhala chiwerengero cha mokwanira ofanana.

N'chifukwa chiyani muyenera kudziwa? Ndiye, kuti index waukulu, umene masamu pa ndimeyi madzi ndi awiri lamkati la chitoliro lapansi. Zochita madzi ntchito ngati mankhwala zitsulo amene atchuka mu mainchesi, ndi mkuwa, zitsulo zotayidwa, zosapanga dzimbiri, opangidwa pa mfundo chinkafunika. Choncho, yolondola mainchesi kumasulira mamilimita chitoliro (ankameteramo ubweya wa kuchuluka kwa mfundo chinkafunika). Pali matebulo wapadera (GOST 3262-75), kukhazikitsa makalata pakati pa mitundu yosiyanasiyana ya mipope ndi magawo awo. Mu ngati mtengo m'munsi ndi kukula mwadzina akutengedwa (ndime) chubu.

Za ulusi umene

Mipope nthawi zambiri ndi kulumikiza. Ndi diameters umatalika kuposa 6 amagwiritsidwa ntchito kuwotcherera, malonda ang'onoang'ono ndi kuluka ndi ulusi, amene magawo zambiri m'kukoma mainchesi. Khwelero ulusi chitoliro - chiwerengero cha ulusi kuikidwa pa wagawo wotereyo. Apa palinso makalata matebulo kusema masitepe mu mamilimita nambala ya ulusi pa inchi. Palinso tebulo mwachidule, yolumikiza inchi kukula cylindrical chitoliro ulusi ndi magawo ake pamwamba pa chomwe chinkafunika. Malinga zindikwanire, makamaka pa threading 3 inchi 87,884 mamilimita limafanana ndi mfundo ya; 86,405 ndi 84.926 (mwadzina kanjedza lakunja pakati, diameters mkati, motero). Nthawi zambiri pangano limene anapangana lija - ndi sayansi, kuphatikiza gulu ndithu mfundo zosiyana, zolinga za zomwe - Kusakaniza lamanja la zinthu ndi zomangidwa kuti ndi ulusi. Maziko a malamulo amenewa zizindikiro inchi chingwe dongosolo.

Ndipo kachiwiri za mainchesi

Dzina "inchi" ndi ena ofanana zambiri amapezeka mu kufotokoza njira zina mafakitale. Mwachitsanzo, mawu akuti "dyuymovka" nthawi zina amatanthauza bolodi makulidwe a inchi kapena bola msomali (Pankhaniyi amakhalanso mainchesi zogwirizana kumasulira mm). Koma si onse. Kufikira tsopano, mfundo "inchi" potchula ndi fixture otchuka ndi mankhwala ena ambiri zitsulo. Koma kuti kutchulidwa njira iyi anachronism, ngati si chifukwa cha chitukuko mofulumira makompyuta zinachititsa kuti mawu atsopano mu zolowa wathu. Maganizo a ena osindikiza mabuku ndi zipangizo zina zambiri amasonyeza madontho pa mamilimita (DPI). Pali mfundo pixels pa mamilimita (ppi), chigamulocho ntchito pamene kutchula chipangizo imapanga kayendetsedwe kapena outputting ndandanda. Zikhulupiriro DPI ndi ppi sayansi zofanana ndi mzake.

Mainchesi monga anayeza ndi zowonetsera a mafoni, oyang'anira, opendekera TV (kale Soviet Union, phindu imeneyi yafotokozedwera cm). Pa zenera ndi kulankhula pang'ono kwambiri.

About pixels ndi fano

Ambiri, akulankhula za kanema kapena zowonetsera ena, anaganizira chizindikiro chofunika kwambiri kukula kwake. Iwo anali n'kukhala mwachizolowezi kwambiri m'litali mwa wokha opendekera (mwachitsanzo, 21 mainchesi mu mm) kuyesera kuzilingalira ngati kuti kuchuluka ichi ndi chokwanira. Komabe, pali mofanana zizindikiro ofunika amene ogula zida zimenezi nthawi samapereka tcheru.

Mapikiselo - ndi luso akuti, ndipo anasamukira ku ntchito tsiku ndi tsiku. Ngati achoke determinations zovuta, ndi mapikiselo angatchedwe zing'onozing'ono indivisible chinthu yeniyeni mtundu chifaniziro. Raster chithunzi kompyuta ndi ya pixels anakonza m'mizere ndi mizati. mfundo TV akusiyanako, koma pano kulankhula za kusamvana luso chipangizo cha, T. e. za luso lake akuimira chiwerengero chachikulu cha mbali (mayunitsi) anasonyeza zithunzi. Kumene, fano lililonse ngakhale kokongola kwambiri ndi quality, apamwamba chiwerengero cha pixels pa wagawo m'dera yotchinga. Izi ndi kale chithunzi ppi (madontho pa anasonyeza inchi). Mtengo wa ppi n'kofunika kwambiri bwino omveka chithunzi quality, choncho ndithu ayenera kuyang'ana pamene kugula zipangizo zoyenerera.

Komabe, osati chimwemwe pixels - kotero, osachepera, akatswiri ambiri amanena. Kufunafuna mkulu-kusamvana kumabweretsa kuwonjezeka lalikulu mu katundu pa khadi zithunzi. Ndiko kuti, ogula TV ndi zina zipangizo ayenera mosamala ndi "ubwino" ndi "kuipa", ndi kusiya pa akadakwanitsira kwa Baibulo chipangizo.

Mainchesi mainchesi ...

Mu mchitidwe computer, tikukumbutsidwa za ukulu uwu ngakhale pamene ife mwachindunji magawo a abulusa zovuta, abulusa litayamba, makhalidwe DVD galimoto. Mainchesi ndi kukula mfundo yaikulu ya masanjidwewo makamera yadigito. Kodi masanjidwewo ndi zimene zimakhudza lili pa kukula kwa chithunzi khalidwe liti? Izi ndi chidwi kwambiri ndi zofunika funso, koma pokambirana ndi mzake.

Kodi kukumbukira kukula kwa inchi?

Man, musati amasiyana kukumbukira kuti manambala, m'pofunika kudziwa zotsatirazi: 4 mainchesi ndalama mamilimita kuti 2.54 * 4, mwachitsanzo, pang'ono kuposa 1 masentimita pamene safuna molondola wapadera, chiwembu ngati n'zotheka ntchito zina ... zochitika tsiku ndi tsiku.

Pomaliza

Ngati inu kulemba "inchi" kafufuzidwe mu injini aliyense kufufuza, njira ayankhe ndipo ndithudi akulumikiza nkhani ya James Aldridge "lomaliza inchi". Izi ndi yaing'ono, koma kwenikweni kopindulitsa ntchito, zomwe wakhala tingachipeze powerenga mabuku dziko, osati kamodzi anajambula. Kwambiri zomvetsa chisoni nkhani ya mtima wa munthu, ubale wa bambo ndi mwana wamwamuna, quirks la tsoka.

Koma chidwi mutu wa nkhaniyo. Kodi "lomaliza inchi"? Mu nkhani ya mwana zaka khumi anali asanawerengepo ndegeyo, izo zikanakhala zotheka osati kuyendetsa njira yovuta, komanso kuika mu mavuto ndi woopsa. The mwana anatha. The inchi womaliza asanafe kubzala anayamba kunja lisanduke munthu wosiyana - wamkulu amene ali ndi udindo, izo yafotokozedwa ndi nkhope latsopano mu ubale tsogolo la bambo ndi mwana. Choncho si nthawi zonse zolondola kusonyeza inchi mm - zina phindu zimenezi zimafuna zosiyana ndi zofanana.
