Cov kav hlau plaub fab lossis plaub fab feem ntau siv rau hauv cov haujlwm tsim kho thiab feem ntau yog siv rau kev txhawb nqa kev teeb tsa yeeb nkab, kev nkag mus rau qhov chaw ib ntus, cov haujlwm fais fab, keel kho kom zoo nkauj, thiab lwm yam.
Thaum qhov loj ntawm cov yeeb nkab hlau plaub fab loj txaus, peb tuaj yeem tsis quav ntsej txog qhov cuam tshuam ntawm cov ces kaum puag ncig ntawm qhov hnyav, piv txwv li, cov kav dej plaub fab hauv cov kav dej, qhov hnyav poob los ntawm plaub lub ces kaum puag ncig yog qhov tsis tseem ceeb rau ib ntu loj heev.
Txawm li cas los xij, rau cov yeeb nkab hlau me me uas muaj plaub fab, cov yeeb nkab hlau plaub fab, nws yog qhov tsim nyog los xav txog lub vojvoog ntawm cov ces kaum puag ncig R thaum xam qhov hnyav. Feem ntau, qhov kev xeem tsis suav nrog qhov sib txawv ntawm qhov hnyav li ntawm 5% txog 10%, uas cuam tshuam nrog tus nqi ntawm cov tuam txhab tsim khoom nyias. Yog li yuav ua li cas xam qhov hnyav ib 'meter' ntawm cov yeeb nkab hlau plaub fab nrog R ces kaum?
Yuav kom xam qhov hnyav ib chav ntev ntawm qhov profile, feem ntau peb yuav tsum nrhiav thaj tsam ntawm qhov seem thiab tom qab ntawd muab nws sib npaug los ntawm qhov ceev ntawm cov khoom sib xws, thiab peb tuaj yeem tau txais nws qhov hnyav ib chav.
Rau lub raj plaub fab uas qhia hauv qab no, peb tuaj yeem tau txais thaj tsam hla A = H*B-(H-2t)*(B-2t) rau tag nrho seem yog tias peb tsis xav txog qhov cuam tshuam ntawm R-lub kaum sab xis.
Thaum lub vojvoog ntawm lub ces kaum sab nraud paub tias yog R, peb tsuas yog ntxiv thaj tsam ntawm lub thaiv xiav thiab rho thaj tsam ntawm lub thaiv liab (raws li pom hauv daim duab hauv qab no) kom tau thaj tsam tiag tiag ntawm seem. Thiab, rau feem ntau cov raj plaub fab, cov ces kaum sab hauv thiab sab nraud yog tib lub voj voog nruab nrab, yog li lub vojvoog sab hauv ntawm lub ces kaum r = Rt. Tom qab peb xam tawm cov ntsiab lus no, peb tuaj yeem yooj yim nrhiav tau cov mis cheeb tsam.
Tsis tas li ntawd xwb, hauv cov lus qhia "GBT 3094-2012 cov yeeb nkab hlau uas zoo li tus txias", tau muab ib daim ntawv qhia txog qhov hnyav ib zaug xwb, nws txoj cai xam thiab kuv tau hais los saum toj no kuj zoo ib yam, koj tuaj yeem xa mus rau daim ntawv qhia hauv qab no.
Saib cov mis, peb tuaj yeem pom tias tus nqi ntawm R hauv qhov kev qhia tshwj xeeb yog txiav txim siab los ntawm phab ntsa tuab ntawm cov yeeb nkab hlau, yog li thaum koj tsis paub tus nqi R tshwj xeeb rau ntau npaum li cas, koj tuaj yeem coj tus nqi raws li qhov kev qhia tshwj xeeb, uas yog -
R = 1.5 npaug ntawm phab ntsa tuab thaum phab ntsa tuab yog ≤6mm. Thaum phab ntsa tuab > 6mm, R = 2 npaug ntawm phab ntsa tuab
Hauv kev xyaum ua, peb kuj tuaj yeem xam qhov hnyav ntawm cov raj duab plaub fab nrog cov ces kaum puag ncig ncaj qha siv cov cuab yeej ntawm peb pov tseg.

Yuantai Delun feem ntau yog koom nrog "cov yeeb nkab hlau plaub fab", "cov yeeb nkab hlau plaub fab" thiab "yeeb nkab hlau puag ncig", peb tuaj yeem sab laj thiab xaj nrog rau peb qhov xwm txheej. Thaum kawg, los ntawm kev nyem lub pob daim ntawv ntawm kaum sab xis hauv qab, peb tuaj yeem kawm paub ntau ntxiv txog cov yam ntxwv tshwj xeeb, suav nrog thaj chaw thiab cov khoom siv kho tshuab ntawm qhov profile, uas muaj cov ntsiab lus ntxaws heev.
