Okuhambelana A4?

Nsuku zonke, ngamunye wethu kufanele isebenze imibhalo, izincwadi, omagazini isibambo, silondoloze ukuxhumana noma ukuthayipha imibhalo elektroniki. Lapho efeza lezi zindaba isimiso, thina ungacabangi ngokuthi ingakanani idokhumenti iyabonakala, kodwa ngiyazibuza ukuthi kungani injalo, nokuthi ngokuvamile kusho A4 owaziwa?! Ake sibone, ukuthi yini ifomethi.

A4 usayizi wephepha

A4 - kuyinto usayizi wephepha owaziwa, ukwamukelwa kwenkolelo-ze iyunifomu imethrikhi ISO-216 ejwayelekile. A4 kuyinto 21 cm * 29.7. Funda lezi zimiso ilula: konke okudingekayo - lokhu ithephu (umbusi), futhi ngqo ephepheni. Nokho, kungani sikhethwe ngobukhulu idatha futhi kungani ukucacisa lezo milimitha - masizame ukuqonda.

Umlando omncane

Kuyaziwa ukuthi zonke brilliant eyaziwa - lula! A4 lwenzelwe khona uma sinqume ngesigamu, uthola neengcezu ezimbili ezifanayo maqondana ngosayizi wasekuqaleni. Ukuze inguqulo yasekuqaleni Umdwebo lathathwa endaweni 1 imitha square (futhi uma kwenzeka ncamashi lokho amaqembu 118,9 amasentimitha (ubude) * 84.1 amasentimitha, futhi zonke Ubukhulu eyaziwa -. It nemikhiqizo sika, ihlukaniswe ngesakhiwo ezithile Ngakho, Ngokwesibonelo, uma ifomethi ishidi A0 ahlukaniswe isigamu, sithola for takhiwo ezimbili ishidi A1, njll Ngakho, ubukhulu ishidi A4 - A3 uhhafu we ishidi njalo-aspect ratio, elichazwa ngu Lichtenberg isilinganiso.

Eqinisweni, Uma unganakile, ingane isici format Standardization onjalo uletha ukuphila abanye ngokuqiniseka ukuthi, yebo, abathintekayo kuzo zonke izigaba nemibhalo. Ekuqaleni kwekhulu elidlule, osayizi iyunifomu ibhizinisi imibhalo, izincwadi, amaphepha kwakungafanele. imboni ngamunye onguchwepheshe iphepha ukukhululwa, ubukhulu wakwenza uwedwa, futhi lokhu, esikhundleni salokho, yenza ngokuphazamiseka okukhulu kuya inzuzo nsuku zonke kwemibhalo.

Ngo 1768, G. Lichtenberg (usosayensi German) wasikisela ukuba kubhalwe ephepheni, aspect ratio okungase imelelwa amayunithi afanele kuya impande square amabili, uzoba Usayizi 2 calandze ezifanayo (uma pre-eligoqiwe ngesigamu). Esinye isazi sezibalo German (V.Portsmann), ngokusekelwe lo mbono, ezihlongozwayo njengoba isisekelo izilinganiso iphepha osayizi. Futhi ngemva kweminyaka embalwa enginakho yonke iYurophu, futhi kamuva umhlaba wonke kwi amazinga iyunifomu.

Fields of kwesicelo

Namuhla, kunamabandla ezihlukahlukene ifomethi, ngisho wonke yochungechunge. Ezinye zasebenzisa akuvamile, kuyilapho ezinye ziba ngokuqinile linamathele ekuphileni kwethu kwansuku zonke. Ngokungangabazeki, ethandwa kakhulu ngobukhulu A4. Sibizwa nangokuthi ngokuthi iphrinta iphepha, ihhovisi iphepha, evamile noma elivamile. Kodwa lokhu akusho ukuthi ubukhulu isetshenziswa kuphela empilweni yansuku zonke, phezu Kunalokho, indinganiso ngokuziphatha zonke izinhlobo ezimali imibhalo, umsebenzi wokunyathelisa nokuthutha ukuthayipha. Ngaphezu kwalokho, ngaphambi kokuba kunyatheliswe lochwepheshe kuvame kakhulu ukuba kusetshenziswe njengoba kuba A4. Usayizi iningi amafomu, amarekhodi, amaphepha isayensi, njll It sifana ncamashi lokhu format.

Usayizi wekhasi futhi imingcele

Isimanga siwukuthi kodwa kulendawo nethonya elikhulu kakhulu ekuphileni ngokuvamile nokuxhumana ngokukhethekile, esikhathini sethu ubuchwepheshe okusezingeni eliphezulu namakhompyutha. Ngaphezu kwalokho, share sengonyama ashicilelwe isebenza kuze izinguqulo nje electronic, futhi kubalulwe ku A4 format. A4 usayizi Ishidi 210 * 297 mm.

Khumbula ukuthi lapho esebenza izinhlelo zekhompyutha ukuthayipha kuyadingeka, okokuqala, hlola usayizi wephepha kanye eziseceleni, njengoba abanye umehluko kungaba ngisho uma nibeka "okuzenzakalelayo".

Ukufakwa kanye nosayizi Amasimu kulawulwa izincomo GOST futhi kumele ithobele amanani alandelayo (okungenani):

• kwesokunxele, phezulu, imiphetho phansi - 20 mm;
• imajini engakwesokudla - 10 mm.

Uhlaka photo ejwayelekile

Ozimele wabonakala isikhathi eside ngaphambi ukuvela izithombe ngokwabo. Noma kunjalo, ayenenjongo ukuhluka futhi ukhonza khombisa imisebenzi yobuciko yobuciko. Babedalelwene zonke izinhlobo izinto-ngokhuni atholakale ngegolide namatshe ayigugu uzimele. Ngakho-ke, lapho isithombe wabonakala, kwakungekho inkinga nge indlela zingahlelwa. Futhi cishe kuzo zonke ekhaya kwakutholakala hhayi isithombe olulodwa elenga odongeni noma libekwe etafuleni e luhlaka enhle.

With ukuthuthukiswa izithombe umkhakha isungule futhi phelelisa ukukhiqizwa ozimele. Esikhundleni omkhulu wokhuni nensimbi weza imikhiqizo lula, okumnandi futhi akukho ngaphansi eqinile futhi iqine plastic, metal Alloys, ingilazi nokunye. ekwakhekeni yabo kanye nokusetshenziswa baba zisabalele. Kodwa naphezu kwalokhu, ngo yimuphi amagumbi namazinga omhlaba wonke ayebheke okufanayo. Ngakho, izilinganiso Uhlaka zivumelana A4 usayizi kudala usayizi ofanayo nabanye ukubekezelelana, futhi kungenzeka ukuthi izinguqulo ezimbili: 20 cm 30 cm 21 cm 30 cm.

isiphetho

iphepha ngamazwe abaziwayo (ISO) amazinga enezinto eziningi uchungechunge (nge Izigaba therein) osayizi obschestandartizirovannyh. Kodwa ifomethi ethandwa kakhulu namuhla usayizi A4. Phrinta leli format isekelwa wonke, ngaphandle kokukhetha, abanyathelisi ejwayelekile. A4 (210 * 297 cm) - standard jikelele kanye esetshenziswa kakhulu njalo idokhumenti format, ezingokwenyama (ephrintiwe) kanye version electronic. Ukwazi imingcele yayo, ungahlala ilungile futhi ngendlela efanele enze wonke umsebenzi.
