Ubude nosayizi wensimbi

I. Ubude nosayizi wensimbi

Usayizi wobude bensimbi usayizi oyisisekelo kakhulu kuzo zonke izinhlobo zensimbi, ubhekisela kubude, ububanzi, ukuphakama, ububanzi, irediyasi, ububanzi bangaphakathi, ububanzi bangaphandle kanye nobukhulu bodonga njalo njalo. Amayunithi asemthethweni okulinganisa ubude bensimbi yimitha (m), isentimitha (cm), i-millimeter (mm). I-intshi nayo isetshenziswa ekusetshenzisweni kwamanje, kodwa akuyona iyunithi esemthethweni yokulinganisa.

Ubukhulu bebanga lensimbi
Ukunquma usayizi webanga lensimbi kuyindlela ephumelelayo yokonga izinto. Umbusi webanga yilowo lapho ubude noma ubude nobubanzi bungekho ngaphansi kosayizi othile, noma lowo lapho ubude noma ubude nobubanzi bulethwa ngaphakathi kobubanzi bezilinganiso. Iyunithi yokukhiqiza ingakhiqiza futhi ihlinzeke ngokwezidingo zosayizi.

Ubude obungapheli (ubude obujwayelekile)
Lapho usayizi womkhiqizo (ubude noma ububanzi), usethelwe ngendlela ejwayelekile ngaphakathi kobubanzi, futhi ungadingi usayizi oqondile obizwa ngokuthi izinyawo ezingenamkhawulo. Ubude obungenamkhawulo bubizwa nangokuthi ubude obujwayelekile. Izinto zensimbi ezilethwa ngesilinganiso esingenamkhawulo ziyamukeleka uma nje zilethwa ngaphakathi kobude obucacisiwe. Isibonelo, ngensimbi evamile eyindilinga engengaphezu kuka-25mm, ubude bayo obuvame ukubizwa ngokuthi u-4 ~ 10m, yonke insimbi eyindilinga ngaphakathi kwalolu hlu ingalethwa.

3. Ubude

Ukunqunywa kube usayizi ohleliwe njengoba kudingeka nge-oda kubizwa ngokuthi usayizi. Uma ukulethwa kwenziwa kube ubude obuhleliwe, izinto zensimbi kumele zibe nobude obuchazwe ngumthengi kwinkontileka ye-oda. Isibonelo, uma inkontileka ithi izimpahla zilethwa ngobude obuhleliwe obungu-5m, izinto ezilethiwe kumele zibe ubude obungu-5m. Noma yiziphi izinto ezimfushane noma ezinde kune-5m azivunyelwe. Kodwa empeleni, ukulethwa akukwazi ukuba konke kube ubude obungu-5m, ngakho-ke kushiwo ukuthi ukuphambuka okuhle kuvunyelwe esikhundleni sokuphambuka okubi.

Izinyawo eziphindwe kane

Ngokusho kosayizi omisiwe we-oda elidingekayo ukuze kunqunywe yonke i-multiple libizwa ngokuthi i-multiple. Ubude bensimbi kumele bube yi-multiple ehlanganisiwe yobude obuchazwe nguMthengi kwinkontileka ye-oda (ebizwa ngokuthi unyawo olulodwa) (kanye nokuvulwa kwesaha). Isibonelo, ikhasimende lidinga kwinkontileka ye-oda ukuthi ubude bonyawo olulodwa bube ngamamitha angu-2, ngakho ubude bungama-4m uma kunqunywa kube ngamafidi amabili, ama-6m uma kunqunywa kube ngamafidi aphindwe kathathu, bese kufakwa umlomo owodwa noma emibili yesaha ngokulandelana.

Inani lokusika lichazwe ku-standard. Uma usayizi ulethwa, kuvunyelwe ukuphambuka okuhle kuphela, futhi akukho ukuphambuka okubi okuvunyelwe.

5. Izinyawo ezimfushane

Irula elifushane ubude balo bungaphansi komkhawulo ophansi wobude obunganqunyiwe obuchazwe ku-standard, kodwa hhayi ngaphansi kobude obuncane obuvunyelwe, libizwa ngokuthi irula elifushane. Isibonelo, indinganiso yepayipi lamanzi negesi ibeka ukuthi amapayipi ensimbi amafushane angu-2-4m ubude avunyelwe ku-batch ngayinye. Ama-4m angumkhawulo ophansi wobude obunganqunyiwe, kanti ubude obuncane obuvunyelwe bungama-2m.

6. Izinyawo ezincane

Umbusi omncane yilowo ububanzi bawo bungaphansi komkhawulo ophansi wobubanzi obungenamkhawulo obuchazwe ku-standard, kodwa hhayi ngaphansi kobubanzi obuncane obuvunyelwe. Kumelwe kunakwe isikali kanye nesilinganiso esincane kakhulu esichazwe ku-standard efanele lapho kulethwa izimpahla ngezikali ezincane.
