Nyob rau hauv Feem ntau, qhov zoo tshaj plaws txheebze vaum ntau yam rau cov ntaub ntawv chaw ib puag ncig yog 45% mus rau 50%. Tau siab tshaj lub qub av noo theem nyob rau hauv cov huab cua yuav corrode tus tes hloov qhov kab, uas nyob rau hauv lem ua rau lub ntaus ntawv mus rau tsis thiab malfunction. Nyob rau hauv ib cov ntaub ntawv ua apparatus, ib tug Circuit Court board uas absorbs noo noo (absorbs noo noo) thiab nthuav ntawv cog lus raws li cov av noo theem fluctuates. Qhov kev nthuav thiab contraction ntawm cov boards yuav ua kev puas microelectronic circuits thiab luam board plugs. Conversely, tsawg humidity yuav tsim static hluav taws xob, uas yuav cuam tshuam nrog rau tej lag luam los ntawm cov khoom thiab puas siv hluav taws xob Cheebtsam.
Leej av noo tswj yog qhov tseem ceeb rau cov ntaub ntawv cov chaw, neeg rau zaub mov chav, thiab lwm cov chaw uas rhiab hluav taws xob khoom yog muab tso rau. Thaum tus kwv tij ntub noo nce siab, rau cov pa dej nyob rau hauv lub tshuab hluav taws xob Cheebtsam lossis dielectric khoom nto tsim tau ib cov dej zaj duab xis, yooj yim ua rau cov tsim ntawm hluav taws xob Cheebtsam ntawm lub nkag. Thaum cov av noo yog heev tsawg, nws yog ib qho yooj yim los mus tsim ib tug ntau dua electrostatic voltage. Sim kawm qhia tias: nyob rau hauv lub computer chav tsev, yog hais tias tus txheeb ze humidity ntawm 30%, cov electrostatic voltage mus 5000V; txheeb ze humidity ntawm 20%, cov electrostatic voltage mus 10000V. Tej yam uas zoo li qub voltage rau computer cov khoom yog cuab kev. Yog li ntawd, nyob rau hauv lub cav chav tsev, cov kev cai ntawm qhov ntub noo ntau yog 40% mus rau 70%, qhov no luv yog tag nrho cov ntau yam nyob rau hauv lub teb chaws.
