I. Cov qauv xa ntawv yooj yim
1. Qhov Chaw Yuav Tsum Tau: Tshaj tawm hauv qhov chaw tseem ceeb thiab pom tau yooj yim, qhov zoo ntawm qhov muag (kwv yees li 1.5-2.0 meters). Lub kaum sab xis ntawm lub dav hlau thiab qhov muag yuav tsum tsis pub tsawg tshaj 75 degree. Tsis muaj qhov cuam tshuam yuav tsum tau muab tso rau pem hauv ntej ntawm lub cim kom tiv thaiv kev nyeem ntawv. Tsis txhob tshaj tawm rau cov khoom txav tau xws li lub qhov rooj lossis qhov rais.
2. Txoj Cai Kev Npaj: Thaum ntau daim ntawv pov thawj kev nyab xeeb tau tshaj tawm ib txhij, lawv yuav tsum tau teem caij raws li hauv qab no: Ceeb toom (daj), txwv tsis pub (liab), Kev qhia (xiav), thiab Ceeb toom (ntsuab), los ntawm sab laug mus rau sab xis thiab saum toj mus rau hauv qab. Cov ntawv sau uas muaj cov tshuaj lom neeg yuav tsum tau muab cais rau hauv thawj kab.
3. Txhim kho cov kev xav tau: Siv cov khoom siv dej tsis zoo thiab cov nplaum ruaj khov lossis cov ntsia hlau / hooks kom ruaj ntseg daim ntawv lo, kom ntseeg tau tias nws tsis poob thaum thauj thiab khaws cia. Cov ntaub nplaum tshem tau tuaj yeem siv rau kev teeb tsa ib ntus. Daim ntawv lo yuav tsum ncaj thiab tsis qaij, tig ntsej muag ncaj qha. II. Cov Lus Qhia Tshwj Xeeb rau Cov Tshuaj Tiv Thaiv Kev Nyab Xeeb Kev Nyab Xeeb
1. Qhov chaw sib sau ua ke rau ntau hom ntim khoom: Rau lub nruas / lub raj mis - zoo li lub ntim, daim ntawv lo yuav tsum tau muab khi rau sab; rau lub thawv - zoo li lub ntim, nws yuav tsum tau affixed mus rau qhov kawg lossis ib sab tseem ceeb; rau lub hnab / pob ntim, nws yuav tsum tau affixed rau ib qho tseem ceeb tag nrho qhov chaw. Ob lub ntim ntim sab hauv thiab sab nrauv yuav tsum muaj cov ntawv sau sib xws.
2. Rau dual- cov khoom lag luam phom sij (cov khoom lag luam uas muaj tshuaj lom neeg thiab cov khoom txaus ntshai), daim ntawv thauj khoom tuaj yeem muab rov qab rau - rau - rov qab nrog GHS daim ntawv lo kev nyab xeeb. Yog tias daim duab rov ua dua, cov qauv sib npaug sib xws hauv GHS yuav tsum raug tshem tawm.
3. Rau cov thawv uas muaj kev phom sij tsis tau raug tshem tawm tag nrho, daim ntawv lo kev nyab xeeb yuav tsum tsis txhob muab tshem tawm yam tsis tau tso cai. Lub voj voog hloov tshiab ntawm daim ntawv lo yuav tsum tsis pub tshaj 5 xyoos.
III. Tom ntej no Kev Saib Xyuas thiab Kev Tswj Xyuas
Tsis tu ncua xyuas cov ntawv rau kev puas tsuaj, fading, lossis cuam tshuam, thiab hloov lossis ntxuav tam sim ntawd. Thaum qhov kev teeb tsa lossis cov txheej txheem hloov pauv, kho cov ntawv sau npe raws li kev ua haujlwm txuas ntxiv ntawm cov ntaub ntawv ceeb toom.
