WFP nyob rau hauv lub qhov rais tu?
WFP yog cov tsiaj ntawv rau dej pub rau haus cov ncej, lub ntsiab ntawm cov kev xav tau ntawm cov khoom siv sab nraum zoov ntau dua, tshwj xeeb tshaj yog Windows, cov khoom siv plua plav yog tus yuam sij mus rau sab hauv!
Siab npaum li cas yuav lub qhov rai tsev ntxhua khaub ncaws ncav cuag?
Qhov no nyob ntawm ncua ntev ntawm tus ncej. Rau peb, ib qho ntev ntev yog 85 ko taw, hauv carbon fiber.
Cov ntaub ntawv siv telescopic ntawm telescopic tu ncej?
Cov ntaub ntawv nquag tshaj plaws rau telescopic tu ncej yog: carbon fiber, iav fiber ntau lossis txhuas.
Aluminium: Tus nqi qis thiab lub teeb yuag thiab lub teeb yuag, tab sis yooj yim rau corode hauv cov chaw noo noo thiab yooj yim rau deform.
Fiberglass: lub teeb yuag, corrosion-resistant, nws yuav tsum tau sau tseg tias: sib txawv hom khoom, tus nqi sib txawv heev.
Carbon Fiber: Lub teeb ceeb, zoo corrosion tsis kam, tsawg coefficient ntawm thermal expansion, kuj, tus nqi siab, nkig.
