Duo Yav dhau los Ntawv Tshuab 

Case 2:

Cov neeg siv khoom qee zaum tsim cov ntawv hnyav, vim lub teeb yuag daim ntawv tuab, lub zog, thiab lwm yam nrog qhov ntsuas qis. Thaum lub tshuab ntawv ua haujlwm, thiab cov khoom siv tshuab ntawv yog huv si yam tsis muaj kev cuam tshuam pom tseeb, feem ntau cov npoo ntawm daim ntawv lub vev xaib ua rau lub tshuab ntawv tawg, thiab cuam tshuam rau kev ua haujlwm ntawm cov ntawv tshuab.

Thaum peb cov engineers tuaj txog ntawm daim ntawv zeb thiab nthuav dav tham nrog tus thawj tswj xyuas cov ntawv zeb, thiab nthuav dav xyuas cov ntawv zeb. Tom qab ntawd peb cov engineers qhia txog qhov teeb meem ntawm cov tswv yim daws teeb meem, nyiam ntxiv dag zog rau ib feem ntawm daim ntawv, lub tshuab nqus tsev nqi ntawm daim ntaub xovxwm yog me ntsis qis dua tus nqi tiag tiag 0-2mbar thiab lwm cov lus pom zoo.

Tom qab kev txhim kho cov neeg siv khoom, lub tshuab ntawv tsis tawg ntawm ntug dua hauv cov khoom qub.
