Cov Khoom Siv Cov Khoom Siv thiab cov nqi kho kom haum yuav tsum ua kom tau raws li lub teb chaws tus qauv thiab raug txheeb xyuas los ntawm MTC.
Geometry & Txheem Ranges
Cov qauv hauv tebchaws txhais tau tias ib tsev neeg ntawm cov channel ntau thiab tsawg los ntawm kev tsim qauv (piv txwv li, C150 × 6. {{{{} {} {} {} {} {} {} Nplooj duab). Cov tsis raug nyob hauv ib lub rooj txheem txheem:
Qhov tob (H){{0- seem seem ntawm qhov siab.

Faq Ceev
Q:Dab tsi yog "lub teb chaws tus qauv" txhais li cas rau cov kauj vab?
A:Nws txhais tau tias cov channel geometry, thev naus laus zis, kev sim ua raws li cov qauv hauv lub tebchaws lossis cov kev ua tau zoo heev thiab kev lees paub hauv kev sau ntawv cog lus.
Q:Cov ntaub ntawv twg yuav tsum muaj cov engineers siv rau kev tsim?
A:Siv cov ntaub ntawv hauv tebchaws cov qauv (cheeb tsam, IY, SX, SY, SY, SY, R) lossis COIE} Daim ntawv pom zoo cov qauv rau cov qauv kos duab.
Q:Kuv puas tuaj yeem hloov chaw ib lossis ASTM channel rau GB channel?
A:Qhov chaw hloov yog ua tau yog tias lwm ntu kev hloov pauv ntu thiab cov phiaj xwm / kev tswj hwm / kev tswj hwm ib txwm yog cov cai ua haujlwm.
Yog tias koj xav tau, Kuv tuaj yeem:
Saib thiab muab ntu ntu ntu thiab cov khoom rau ib tus qauv hauv ntiaj teb (thov qhia lub teb chaws twg / qauv); lossis
Nqa koj cov ntaub ntawv luv thiab thauj cov ntaub ntawv thiab tshaj tawm3 National - Txheem channelCov neeg sib tw (nrog cov khoom muaj zog, Mass / M thiab Dabtsi yog khoov / deflection tshev).
Qhia rau kuv lub teb chaws tus qauv uas koj xav tau (lossis tsuas yog muab qhov ntev) thiab kuv yuav rov qab cov ntu cov lus pom zoo thiab cov lus pom zoo.
