Muaj ib lub sij hawm ntawm lub xyoo thaum pos huab qhov rais yog mob taub hau rau ntau txhiab tus neeg tsav tsheb. Qhib lub tshuab cua txias? Qhib qhov rais? Qee zaum txawm tias qhov no zoo li tsis ua haujlwm. Tab sis raws li lawv hais, kev tiv thaiv zoo dua li defogging. Los yog nws kho? Tom ntej…
Foggy qhov rais yog qhov tshwm sim ntawm cov dej noo hauv cov neeg caij tsheb, yog li yog tias peb tswj kom nqus tau nws, qhov teeb meem yuav daws tau.
Txhua yam nws yuav siv yog ib nkawm thom khwm thiab qee cov khoom siv absorbent. Yog tias koj muaj miv, koj yuav muaj silica crystals hauv tsev, lawv ua haujlwm zoo kawg nkaus! Saib nws nrog video hauv qab no:
Tab sis yog tias koj tseem tsis tau tswj kom daws tau qhov teeb meem ntawm cloudy iav, tsis txhob poob siab. Mark Rober, yav dhau los NASA engineer, tig mus rau kev tshawb fawb kom xaus rau iav fogging. Nrog rau plaub kauj ruam no nws muaj peev xwm defog lub tsheb lub qhov rais ob zaug sai li sai tau:
- Qhib qhov cua / rooj zaum (siab tshaj)
- tig lub tshuab cua txias
- Tshem tawm cov cua ncig hauv cov neeg caij tsheb
- Qhib lub qhov rais me ntsis
Yuav kom paub seb cov txheej txheem dej vapor condensation ntawm lub tshuab ua haujlwm li cas, Mark Rober piav qhia txhua yam hauv cov yeeb yaj kiab hauv qab no:
