Yuav ua li cas yog lub scale ntawm daim duab?

Ua ntej koj yuav pib nrhiav nyob rau hauv tus txheej txheem teev ntawm daim duab, nws yuav tsum tau to taub hais tias nws yog ib tug muab tswvyim. Yog li, xws li ib tug nqi yog feem ntau ib tug piv ntawm ob linear qhov ntev. Txawm li cas los, feem ntau hu xws ib tug txhais lus ntawm no txhais, raws li tus piv ntawm qhov luaj li cas ntawm daim duab mus qhov loj ntawm lub tiag tiag kwv. Thiaj li, peb yuav rightly yuav lam xav tias lub saum toj no lub sij hawm tau lug siv nyob rau hauv cartography, num, thiab ntawm chav kawm, tsim.

Yog vim li cas yog no tsim nyog?

Raws li hais ua ntej lawm, qhov tiag cov kwv tej zaum yuav muaj yuav tsum tau sufficiently loj loj thiab me me heev. Txawm li cas los, ib tug neeg yuav tsis kos duab dab tsi nyob rau hauv lub neej-loj, raws li rau cov zaub nyob rau hauv ib daim ntawv ntawm daim ntawv, lub tsev npaj yuav yuav tsum tau enormous canvas loj, me, thiab, nyob rau hauv lem, mus recreate me me khoom (xws li nyob rau hauv lub moos mechanism) yuav tsum tau ib tug high degree ntawm kom meej. Raws li ib tug tshwm sim, cov neeg txais los sawv cev rau qhov tsim nyog cov khoom, uas nyob rau hauv ib tug tej yam muaj pes tsawg tus ntawm cov sij hawm luv (los yog muaj zog) rau clarity thiab thiaj li hu "readability" qauv. Tam sim no, muaj kev kawm, kev piv txwv li, GOST "duab scale" uas piav qhia txog tag nrho cov uas yuav tsum tau mus rau hauv daim ntawv thiab sau lub duas paub dluab.

loj cov khoom

Raws li hais ua ntej lawm, rau cov zaub ntawm vaj tse thiab lwm yam loj yam khoom yuav tsum tau siv duab scale thiaj li hu ua yuav txo tau. Lawv yog cov zoo, uas txhais tau tias random sampling yog tsis haum. Cov ntau ces yuav tsum nram qab no qhov tseem ceeb: 1: 2; 2.5; 4; 5; 10; 15; 20; 25; 40; 50; 75; 100; 200; 400; 500; 800; 1000 tauj Cia peb kawm seb yog cov ntaub ntawv ntawm no hom. Yog li, qhov tiag (nyob rau hauv lwm yam lus, tej yam ntuj tso) dimension ntawm ib tug kwv yog qhia nyob rau hauv daim ntawv ntawm cov niam ntawv 1: 1. Thiaj li nrog zuj zus lawm scale drawings piav thawj lub yeej loj (1) raws li los ntawm ib tug xov tooj uas qhia yuav ua li cas muaj ntau zaus nqus yog txo tus txheeb ze mus rau lub tiag tiag qhov ntev. Nyob rau hauv kev tsim kho, nyob rau hauv tas li ntawd mus rau saum toj qauv ntaub ntawv, pointers kuj yuav siv tau 1: 2000; 5000; 10000; 20000; 25000; 50,000.

qhov chaw me me

Nyob rau hauv cov ntaub ntawv uas, yog hais tias tus cev yog tsim nyog los kos tej khoom me me, cov tsoos teev ntawm kev nce nyob rau hauv lub drawings yog siv. Nyob rau hauv cov ntaub ntawv no, muaj xws li ib tug ntau yam ntawm qhov tseem ceeb, tab sis ib tug txheej txheem stipulated feem ntau nquag siv qhov tseem ceeb. Yog li, cov raug tus xov tooj yog raws li nram no: 2; 2.5; 4; 5; 10; 20; 40; 50; 100: 1. Piav ntawm zoo xws li cov ntawv nyeem raws li nram no: ua ntej ib tug xov tooj uas qhia yuav ua li cas muaj ntau zaus cov duab nyob rau hauv daim duab yog nce raws li muab piv nrog rau cov thawj cov kwv. Qhov thib ob tug lej tom qab tom qab cov nyuv qhia tau hais tias tus tiag tiag (aka - tej yam ntuj tso los yog tiag tiag) luaj li cas ntawm cov kwv (yuav tsum tau 1).

xaus

Qhov tsab xov xwm soj ntsuam lub scale ntawm drawings thiab lawv txheem ibyam. Nws yuav tsum tau muab sau tseg tias tus kheej lub hom phiaj, tej yaam num thiab zoom nqi teev nyob rau hauv ib tug tshwj xeeb lub thawv nyob rau hauv tus ncej, txwv tsis pub lub npe hu ua ib tug stamp.
