Kev nug

"Helium yog inert thiab yog cov kua dej tsawg tshaj plaws ntawm tag nrho cov gases, yog li nws yog siv los ua cov pa roj, vim nws inertness, helium yog siv los ua ib feem ntawm cov roj nruab nrab, piv txwv li, hauv kev kho cua sov siv qhov chaw tiv thaiv. xav tau.

Helium yog dav siv nyob rau hauv kev lag luam vuam raws li ib tug inert shielding roj rau arc vuam. Nws kuj tseem siv tau ua ke nrog helium ("leak") detectors los ntsuas qhov ncaj ncees ntawm cov khoom tsim thiab cov tshuab. "
