Cov chaw lag luam nrog lub luag haujlwm rau kev tswj hwm cov khib nyiab siv cov khoom sib txawv ntawm kev ntsuas. Kev tswj hwm cov tuam txhab uas tshem cov ntim khoom ntawm lub thoob khib nyiab los ntawm yards feem ntau suav qhov ntau ntawm cov khoom pov tseg. Cov av nyom thiab rov qab nroj tsuag txais cov khoom pov tseg, feem ntau yog ntau tons. Nyob rau tib lub sijhawm, cov lag luam yuav tsum khom nqi nrog txhua lwm tus, thiab raws li - xam tus nqi ntawm qee qhov ntsuas ntawm qhov ntsuas ntawm cov khib nyiab.
Nws yog qhov tsim nyog
- - Cov khoom siv rau lub khob ntim khoom;
- - tshuab xam zauv.

Kuaj seb koj khib nyiab dabtsi. Cov khib nyiab muaj cov qhov sib txawv thiab, raws li, cov sib txawv ntawm cov sib txawv yog siv hauv cov lus suav. Yog tias koj thaj chaw ib cheeb tsam tau coj los sau cov khoom sib cais ntawm cov khoom pov tseg hauv tsev, nrhiav cov ntom ntawm cov yas hwj, daim duab ntawv, khob iav, thiab lwm yam. thiab txhuas cov kaus poom. Tab sis qhov ntom ntawm cov iav pleev tag nrho yuav luag kaum npaug siab dua.

Qhov ntom ntawm cov khib nyiab ib txwm tseem yuav ua rau sib txawv. Piv txwv li, ntawm qhov chaw pov khib nyiab uas tsis tau tso cai nws yog 80 kg / cubic meter, nyob rau hauv ib lub taub ntim - los ntawm 180 txog 240 kg / cubic meter, thiab ntawm qhov chaw pov tseg nws txawm tias 500 kg / cubic meter. m. Txiav txim siab nyob rau theem dab tsi ntawm kev ua koj yuav hloov ib chav ua haujlwm rau ib chav.

Muaj qee kis, koj tuaj yeem txiav txim siab qhov kev sim ntawm cov khoom pov tseg hauv lub nroog. Xaiv cov ntim nrog tib hom khib nyiab. Qhov ntau muaj, qhov tseeb tshaj qhov tshwm sim yuav yog. Cov ntim yuav tsum tau ntim raws li tus qauv (uas yog, yuav tsum tsis txhob hla dhau lossis hla dhau). Xam tawm qhov hnyav tag nrho ntawm cov khoom pov tseg hauv nroog thiab faib los ntawm tus naj npawb ntawm cov thawv. Koj yuav tau txais qhov hnyav nruab nrab ntawm cov thoob khib nyiab hauv ib lub thawv. Los ntawm faib rau nws los ntawm ntim, koj yuav pom thaj tsam nruab nrab. Koj tuaj yeem txais tag nrho qhov loj thiab faib nws los ntawm qhov ntim ntawm txhua lub ntim.

Nco ntsoov yuav ua li cas qhia qhov ntim ntawm ib qho twg ntawm nws qhov loj thiab tuab. Nws tuaj yeem xam los ntawm tus qauv V = m / ρ, qhov twg m yog qhov loj ntawm cov tshuaj, thiab ρ yog nws ntom. Los ntawm kev faib cov loj ntawm cov khoom pov tseg hauv lub nroog los ntawm qhov nruab nrab lossis sim ntsuas qhov sib txawv, koj yuav tau txais qhov ntim uas koj xav tau nyob hauv cov cubic meters. Raws li, yog tias koj paub lub ntim thiab qhov ntau tsawg, muab rau lawv kom tau txais qhov ntau hauv tons.
