Yuav ua li cas yog lub kos npe rau ntawm txoj kab uas hla thiab yuav ua li cas nrhiav tau nws nyob rau hauv keyboard?

Pib nyob rau hauv lub thib ob ib nrab ntawm cov XVIII xyoo pua nyob rau hauv ces, cov muaj kiv puag ncig hauv lub XIX xyoo pua, swept thoob plaws ntau lub teb chaws nyob rau hauv Teb chaws Europe thiab lub ntiaj teb no. Nws twb tsiag ntawv los ntawm ceev ceev txoj kev loj hlob ntawm technology thiab muaj ntau lawm. Manufacturing ntawm ntau lawm tsiv los ntawm factories thiab kev cob qhia nyob rau hauv lub loj factories. Txawm li cas los, txoj kev hloov los ntawm ib thiab me me batch ntau lawm los loj, raws li zoo raws li lub division of labor demanded lub creation ntawm ib tug ntau yam ntawm kev tsim thiab kev siv technology tshiab cov ntaub ntawv, uas coj mus rau txoj kev loj hlob ntawm applied disciplines - nqus.

Lub advent ntawm standardization

Kos cia koj ua ib tug graphical sawv cev ntawm cov kwv yuav tsum tau rau nws lawm. Txawm li cas los, rau zus tau tej cov ib yam khoom zoo li no tsis txaus. Tus naj npawb tseem muaj tus loj, teev, kev uas yuav tsum tau, cov ntaub ntawv thiab lwm yam ntxwv ntawm cov khoom. Ntxiv txoj kev loj hlob ntawm ntau lawm tau coj mus rau lub division of labor, thaum lub Cheebtsam yog manufactured nyob rau hauv txawv nroj tsuag, thiab ces assembles cov khoom tiav. Qhov no yuav tsum tau koom ua ke thiab standardization ntawm qhov chaw thiab kos duab ib tiav kev cai. Rau yooj yim thiab xaav kev ntaub ntawv cim tau tau ua tswvcuab, xws li, piv txwv li, lub kos npe rau ntawm txoj kab uas hla los yog thickness, yooj yim nkag qhia yam ntxwv.

Cim: kos npe rau txoj kab uas hla

Standards muab ntau yam cim, uas pab kom sau geometric thiab hauj tsis pom vaj tse: tej yam tshwm sim puag ncig, thickness, lub kaum ntse ntse siab tev taus thiab machining nyiaj. Cov tib kev txhawj xeeb thiab txoj kab uas hla ntawm uas yog txiav txim los ntawm qhov loj ntawm lub qhov thiab lub cev ntawm kiv puag ncig. Lub chord txuas ob lub ntsiab lus nyob rau hauv ib lub voj voog (kheej) thiab dhau los ntawm nws (nws) center, thiab yog hu ua tus kab uas hla. Raws li nws qhia nyob rau hauv cov nuj nqis? Mark nruab nrab txoj kab uas hla ntawm ib lub voj voog, hla-line inclined ntawm ⁴⁵ ° rau hauv lub ntsug nyob rau hauv cov kev taw qhia ntawm clockwise. Nyob rau hauv tej rooj plaub, ib tug Latin tsab ntawv D, uas yog tso cai rau siv nyob rau ib par nrog lub cim tseem ceeb.

txoj kab uas hla kos npe rau hauv Word

Nrog rau txoj kev loj hlob ntawm computer technology feem ntau ntawm cov kev tsim ntaub ntawv pib mus rau cov hloov mus rau hauv hluav taws xob daim ntawv no, uas tswj cov creation, cia, forwarding thiab printing ntawm drawings thiab routings. Yuav kom qhov no kawg, tshwj xeeb cov kev pab cuam los. Piv txwv li, rau ib qho ntawm AutoCAD yog siv, thiab rau cov ntawv luam ntaub ntawv - Lo lus, ib feem ntawm lub Microsoft Office pob. Nyob rau hauv tas li ntawd mus rau lub them software, muaj kuj yog free: NanoCAD, Open Office.

Raws li, peb tsiv thiab cov rooj sib txoos, xws li lub cheeb ntawm lub kos npe rau nyob rau hauv cov kev pab cuam. Nyob rau ib tug standard keyboard layout nws tsis muaj nyob, yog li ntawd, mus ntxig rau nws rau hauv ib daim ntawv tsim los ntawm kev siv ib phau ntawv editor lo lus, koj yuav tsum xeem dhau rau nram qab no txoj kev: "Insert → Cim → Lwm yam cim → hloov lub" Font "nyob rau hauv lub« Cim »→ AE». txoj kab uas hla cim code nyob rau hauv lub "cim (hex)" - 00S6. Vim qhov no caij yog tsis tam sim no nyob rau hauv tag nrho cov fonts, nws yuav tsum tau hloov nrog ib tug hla-tawm "on": "Ø", code - 00D8 nyob rau hauv lub "Unicode (16)."
