Vim li cas qee qhov kev cob qhia plua plav siv cov khaub ncaws tiv thaiv zoo li qub?
Thaum ua haujlwm hauv lub tshuab hluav taws xob, cov neeg ua haujlwm yuav raug kev tsis pom txog qee cov khoom siv hluav taws xob. Tib neeg lub cev yuav tsim hluav taws xob zoo li qub thaum cov txheej txheem txav. Cov xaj no yog qhov tshwj xeeb rau cov hluav taws xob tsis zoo rau electrostatic. Tsis tas li ntawd, cov khaub ncaws peb hnav tau ua los ntawm cov ntaub qhwv ntuj, uas tau yooj yim tsim los ntawm kev txhuam. Kev tswj hluav taws xob ntawm lub Hoobkas hluav taws xob kuj tseem tuaj yeem ua hluav taws xob. Yog li, cov khaub ncaws tiv thaiv zoo li qub hnav los ntawm lub tshuab hluav taws xob tsis yog tiv thaiv qhov zoo thiab kev nyab xeeb ntawm cov khoom xwb, tab sis kuj tiv thaiv kev noj qab haus huv ntawm cov neeg ua haujlwm ntawm kev puas tsuaj.
Vim tias lub cev nws tus kheej muaj hluav taws xob zoo li qub
Nws tsis muaj teeb meem rau nws tus kheej, tab sis nws yog kev tuag rau qee cov khoom me me.
Txhawm rau txiav txim siab txog qhov ua tau zoo thiab puas tsuaj ntawm cov khoom, lub lag luam dav dav yuav ntsuas qee qhov ntsuas.
1: Cov hlua khov kho khau, lub taub hau npog, cov khoom siv hluav taws xob tsis zoo, cov khaub ncaws electrostatic.
