Pob zeb qhov hnyav, ntim, nqi thauj mus los ｜ Cov txheej txheem suav:
1. Yuav ua li cas xam qhov hnyav ntawm marble
Feem ntau qhov tshwj xeeb lub ntiajteb txawj nqus ntawm marble yog 2.5 qhov hnyav (tons) = cubic meters multiplied los ntawm lub ntiajteb txawj nqus.
Qhov tseeb: Siv lub pob zeb 10 cm square los ntsuas qhov kev nqus ntawm koj tus kheej
2. Kev suav cov pob zeb hnyav thiab cov nqi thauj mus los hauv kev suav
Ua ntej nkag siab (lub sij hawm) Pob zeb ntim, tseem hu ua lub voos xwmfab, = ntev * dav * qhov siab pob zeb feem, kuj hu ua ntom.
Qhov ceev los yog tshwj xeeb lub ntiajteb txawj nqus ntawm granite yog hais txog 2.6-2.9 tons ib cubic, thiab qhov ceev los yog tshwj xeeb gravity ntawm marble yog hais txog 2.5 tons ib cubic.
Xam lub pob zeb qhov hnyav: pob zeb ntim lossis cubic * qhov ntom ntom lossis lub ntiajteb txawj nqus tshwj xeeb, uas yog: ntev * dav * tuab * tshwj xeeb lub ntiajteb txawj nqus = pob zeb hnyav, yog tias koj xav paub tus nqi ntawm txhua lub pob zeb (los ntawm qhov chaw ntawm qhov chaw - qhov chaw. ntawm kev siv).
Txoj kev suav yog:
Ntev * dav * qhov siab * proportion * tons / nqe = nqe ntawm txhua pob zeb.
3. Kev suav ntawm pob zeb ntim, tuab thiab hnyav
(1) Tsuas yog suav cov khoom:
1 txuj = 303 × 303㎜;
1 ping = 36 ping;1 m² (㎡) = 10.89 ping = 0.3025 ping
Kev suav cov txuj ci: ntev (meter) × dav (meter) × 10.89 = txuj ci
Piv txwv li:
Nrog rau qhov ntev ntawm 3.24 meters thiab dav ntawm 5.62 meters, nws cov txuj ci khoom yog xam raws li nram no → 3.24 × 5.62 × 10.89 = 198.294 txuj ci = 5.508 ping
(2) Thickness xam:
1. xam hauv centimeters (㎝): 1 centimeter (㎝) = 10 mm (㎜) = 0.01 meters (m)
(1) Feem ntau thickness ntawm granite: 15mm, 19mm, 25mm, 30mm, 50mm
(2) Feem ntau thickness ntawm marble: 20mm, 30mm, 40mm
(3) Cov tuab tuab ntawm Roman pob zeb thiab cov pob zeb tuaj txawv teb chaws: 12mm, 19mm
2. Muab xam rau hauv cov ntsiab lus:
1 point = 1/8 nti = 3.2mm (feem ntau hu ua 3mm)
4 ntsiab lus = 4/8 nti = 12.8mm (feem ntau hu ua 12mm)
5 ntsiab lus = 5/8 nti = 16㎜ (feem ntau hu ua 15㎜)
6 ntsiab lus = 6/8 nti = 19.2mm (feem ntau hu ua 19mm)
(3) Nyhav xam:
1. Granite thiab marble: 5 ntsiab lus = 4.5㎏;6 ntsiab lus = 5㎏;3 ㎝ = 7.5㎏ 2.
Roman pob zeb: 4 ntsiab lus = 2.8㎏;6 pkt = 4.4㎏
4. Kem pob zeb, pob zeb tshwj xeeb pob zeb pob zeb kem yog qhov dav dav heev, thiab cov duab sib txawv, tsis muaj cov qauv los qhia ncaj qha.
Hauv paus nqe = tus nqi + nyiaj tau los = cov khoom siv + nqi ua haujlwm + cov nyiaj tau los tag nrho
(1).Tus nqi ntawm cov ntaub ntawv yog ib qho yooj yim los xam, thiab cov nqi ua yog txawv heev vim qhov sib txawv ntawm qhov nyuaj ntawm kev ua cov duab ntawm lub pob zeb lub tog raj kheej, cov khoom siv sib txawv, thiab cov khoom siv, kev ua haujlwm, thiab kev txawj ntse ntawm txhua lub Hoobkas, yog li muaj. tsis muaj txoj hauv kev los xam nws kom raug..
(2).Rau ib co pa thiab yooj yim pob zeb cylinders, nws yog ib qho yooj yim los xam rau ntawm qhov chaw.Nco ntsoov them sai sai rau qhov loj thiab xim xav tau los ntawm cov neeg siv khoom.Tom qab tag nrho, qhov ntev ntawm pob zeb thooj voos kheej kheej yog qhov loj, yog li nws nyuaj rau nrhiav cov blocks uas ua tau raws li qhov loj me, yog li tus nqi tsis siab.Nws tsis yog teem raws li cov pa phaj nqi thiab thaiv tus nqi.Tab sis raws li qhov loj me, ntau yuav siv tom qab.
(3).Yog li ntawd, txoj kev ncaj qha yog tias koj tau ua tiav thiab tsuas yog suav tau tom qab lub sijhawm ntev ntawm kev ua tiav.Feem ntau, cov kws qhia paub txog yuav siv cov qauv empirical los xam.Piv txwv: Peb lub tuam txhab muaj qee cov kab uas nyuaj heev rau kev ua haujlwm ua ntej, thiab lub Hoobkas ua haujlwm tau kwv yees tus nqi raws li kev paub dhau los.Lub tuam txhab ua haujlwm no tau ua cov duab tshwj xeeb thiab kab rau ntau tshaj kaum xyoo.Txawm li cas los xij, vim tias qhov tseeb ntau lawm yog qhov nyuaj tshaj li qhov kev xav, tus nqi tau nce los ntawm 50% (lub Hoobkas nws tus kheej tau hais), tab sis vim yog lub Hoobkas nws tus kheej miscalculation, tus nqi tseem zoo ib yam li tus nqi qub.Txwv tsis pub, yog tias nws kwv yees los ntawm peb lub tuam txhab, nws yuav ua tiav, thiab nws yuav ploj.
(4).Yog tias koj yog ib lub tuam txhab lag luam, nws yog qhov zoo tshaj plaws tsis txhob hais txog cov pob zeb tshwj xeeb xws li cov pob zeb, tshwj xeeb tshaj yog cov txheej txheem nyuaj, los yog nws yooj yim ua yuam kev hauv kev kwv yees.Nws yog qhov zoo dua los hais txog kev ruaj ntseg raws li lub Hoobkas nqi.
