Ⅲ Qhov kev tsim tshwj xeeb rau cov qauv siv cov khoom siv ceev ceev hauv cov dej num hnyav lossis qib tsheb kub?
1.} Cov Qauv Hluav Taws Xob (xws li cov hluav taws xob txuas ntxiv mus rau kev ntsuas kom ruaj khov (xws li ob npaug rau kev txiav txim siab) yog cov hlua khi ntau dua {}
2. high-ceev-ceev cov tsheb ciav hlau yuav tsum sib phim nrog kev co kom pom kev tsheb nqaj hlau, thiab cov hluav taws xob caij nplooj ntoos hlav yuav tsum tau tswj hwm hauv 1mm.
3.}}}}}}} wb thaiv tsev ua tau zoo, thiab kev tiv thaiv lub nrawm dua lossis sib npaug nrog kev cuam tshuam rau cov teeb liab (xws li} qauv).
4.}} anti-anti-rog tsim qauv xav tau simulate 300 lab thauj mus los hauv lub neej), xws li German tus qauv) 571 Xav tau {5} {5}
{5.} huab huab (xws li suab puam permafrost) yuav tsum tau cov ntaub ntawv los tiv thaiv kub ({{2} .
Yuav ua li cas xaiv txoj cai txhawb txoj cai raws li hom pw tsaug zog (ua vaj tse lossis ntoo)?
1. buchers pw yog siv lub tes tsho caij nplooj zeeg, wj} {}, xav tau me ntsis saib xyuas .
2. cov ntoo hauv qab yuav tsum tau kho nrog cov spikes lossis nuv tau yooj yim, tab sis lawv yooj yim rau cov ntaub qhwv lossis cov ntaub qhwv tau yooj yim siv hloov .
3. Qhob cov chaw pw felposion (xws li cov ntoo uas phem)
4. yuav luag txhua qhov kev tsheb ciav hlau siab siv cov neeg pw tsaug zog hauv cov kab qis qis lossis cov kab keeb kwm {{4 4}}
{{0 {0} Cov ntu tshwj xeeb (xws li txuas hniav) yuav siv ob qho tib si clastic ceev rau txhim kho kev co kom txo.
Ⅴ Hauv cov haujlwm thoob ntiaj teb, ua cov txheej txheem nrawm yuav tsum tau raws li cov qauv kev tiv thaiv corrosion (xws li galvanizing, dacromet)?
{{0 {} galvanizing (kub dip / electroplating) yog cov txheej txheem American yog qhov ua kom tuab ntawm ntau dua los yog sib luag rau 50μm.
2. dacromet txheej muaj cov ntsev ua kom tsis txhob muaj 1000 teev thiab ib puag ncig cheeking (xws li Nyiv jis h {2} {3}
