Tsis tas li ntawd, txawm hais tias qhov chaw yog qhov tseeb ua ntej kev tsim khoom, cov khoom siv hnav thiab kev co thaum lub sijhawm ua haujlwm tseem tuaj yeem ua rau kev taw qhia drift lossis instability. Yog tias lub tshuab tsis nres rau kev hloov kho raws sijhawm, daim ntawv misalignment yuav tshwm sim. Yog li ntawd, ntxiv rau kom paub tseeb tias cov kab sib dhos ntawm thawj tus qauv yog qhov tseeb, cov neeg ua haujlwm tsim khoom kuj tseem yuav tsum tau ua qhov chaw kuaj xyuas tsis tu ncua thaum lub sijhawm tsim khoom los tswj qhov raug thiab ruaj khov ntawm cov lus qhia. Daim duab 22 qhia txog kev luam ntawv kom raug.

04/ Kev Sib Txuas Lus
Yog hais tias qhov chaw ntawm thawj folding kauj ruam yog tawm, los yog yog hais tias cov cuab yeej qhov tseeb drifts thaum lub sij hawm ua hauj lwm tas mus li, nws yuav ua rau folding yuam kev, uas yuav ua rau misalignment nyob rau hauv lub kawg assembled phau ntawv. Tsis tas li ntawd, kev tswj tsis raug ntawm cov txheej txheem tsis raug nyob rau hauv ntau txoj kev khi tuaj yeem cuam tshuam ncaj qha rau kev sib dhos: yog tias qhov milling qhov tob rau kev khi zoo meej yog qhov sib sib zog nqus heev, nws tuaj yeem ua rau cov duab tsis tiav ntawm tus txha nraub qaum; yog tias cov kab nrib pleb tsis raug lossis tob txaus, nws tuaj yeem cuam tshuam li cas nplooj ntawv tig, ua rau misalignment; thiab yog tias cov kua nplaum nkag mus rau hauv sewn binding yog sib sib zog nqus heev, nws tuaj yeem ua rau cov duab lo ua ke thiab tsim teeb meem kev sib raug zoo. Qhov tseeb thiab qhov sib xws ntawm cov txheej txheem no yog qhov tseem ceeb rau kev sib tw zaum kawg. Daim duab 23 qhia tau hais tias yog cov ntaub ntawv folded hauv kev khi.

Kev daws qhov teeb meem ntawm kev tsis sib haum xeeb thoob plaws phau ntawv sib kis yog kev ua haujlwm nyuaj thiab muaj ntau cov kauj ruam, tab sis nws tsis yooj yim sua. Qhov tseem ceeb nyob hauv kev sib koom ua ke sib sib zog nqus thiab kev sib tham tsis tu ncua ntawm kev tsim thiab tsim khoom- cov neeg tsim qauv yuav tsum nkag siab tag nrho cov kev txwv ntawm cov txheej txheem, thaum ntau lawm yuav tsum ua raws li cov qauv tsim. Tsuas yog los ntawm kev sib raug zoo, kev tswj xyuas kom zoo, thiab kev kuaj xyuas nruj ntawm txhua kauj ruam tuaj yeem sib npaug ntawm kev nthuav qhia kev kos duab nrog kev ua haujlwm zoo, ua tiav kev sib kis uas ua tiav, nyeem tau yooj yim, thiab muaj kev ntseeg siab siab - zoo. Qhov tseem ceeb, kev sib koom ua ke tsis yog tsuas yog kev xav txog kev ua haujlwm ntawm pab pawg thiab kev ua tiav hauv kev tshaj tawm tab sis kuj yog ib qho kev sib tw tseem ceeb los kov yeej hauv kev txhim kho phau ntawv zoo.
