Classified los ntawm qhov chaw siv:
Muaj cov pa thiab tawg-pov thawj hom: Cov paib hom yog tsim raws li lub teb chaws tus qauv kom tau raws li tag nrho cov kev xav tau ntawm ib puag ncig, nrog rau cov nqi ntawm ob peb puas mus rau ob peb txhiab, thiab tus yam ntxwv yog zoo heev nqi-zoo. Cov ntaub ntawv pov thawj tawg ua tau raws li qhov kev xav tau ntawm cov chaw tshwj xeeb thiab yog me ntsis kim dua.
Classified los ntawm pawg neeg siv:
Rau kev siv hauv tsev thiab kev lag luam: Tus nqi ntawm cov khoom siv hluav taws xob hauv tsev yog li ntawm kaum rau pua pua ntawm yuan, nrog rau cov nqi zoo thiab siv tau yooj yim. Lawv tsuas yog yuav tsum tau muab tso rau hauv qhov chaw xaiv thiab ntsaws rau hauv lub zog hluav taws xob los ua haujlwm, thiab tuaj yeem txuas nrog lub tshuab hluav taws xob txiav tawm kom ua tiav kev ua haujlwm tsis siv neeg thiab txiav cov kev phom sij zais ntawm qhov chaw. Cov khoom siv roj av muaj cov kev xav tau siab heev rau ntau yam ntsuas thiab yuav tsum ua kom tau raws li cov qauv kev nyab xeeb xws li cov qauv hauv teb chaws thiab kev lag luam rau kev siv ntau qhov chaw. Tus nqi ntawm ntau pua mus rau ntau txhiab yuan.
Classified los ntawm kev ua haujlwm:
Muaj ib qho roj av detectors thiab multifunctional detectors: ib qho roj detectors feem ntau yog siv los ntes ib qho roj hauv qhov chaw tshawb nrhiav, thiab kev siv loj heev. Lub multifunctional gas detector muaj xws li rau hauv ib tug gas detector, tsib nyob rau hauv ib tug gas detector, plaub nyob rau hauv ib tug gas detector, thiab Couric gas detector, uas ua tau raws li cov kev xav tau ntawm txawv roj nrhiav kom muaj nuj nqis.
Classified los ntawm kev siv:
Muaj cov cuab yeej nqa tau (lub tes tuav) thiab ruaj khov (nruab, phab ntsa mounted) cov twj paj nruag: cov cuab yeej nqa tau yooj yim uas ua tau raws li qhov xav tau ntawm kev nyab xeeb ntawm cov neeg ua haujlwm hauv tsev rau kev kuaj xyuas cov pa roj ua ntej ua haujlwm, feem ntau nyob ntawm qhov kev siv scenario. Cov hom ruaj khov feem ntau ua tiav qhov kev tshawb nrhiav tsis muaj kev cuam tshuam ntev los xyuas kom muaj kev nyab xeeb ntawm lub xaib, tsis tas yuav tsum muaj kev tswj hwm ntawm cov neeg ua haujlwm hauv tsev, thiab tuaj yeem txuas tau ntse.
Classified los ntawm sampling method:
Muaj hom diffusion thiab twj tso kua mis hom roj ntes: diffusion hom roj ntes tau siv dav thiab muaj tus nqi qis txij li ob peb puas yuan mus rau ntau txhiab yuan. Tus nqi ntawm lub twj tso kua mis nqus roj ntes yog tus nqi siab, feem ntau yog li ntawm ob peb txhiab yuan lossis ntau dua, feem ntau ua kom tau raws li qhov xav tau tshwj xeeb ntawm qhov chaw tshwj xeeb.
Classified los ntawm kev tshawb nrhiav txoj cai:
Kev kuaj pom cov roj hluav taws xob muaj xws li catalytic combustion hom, semiconductor hom, thermal conductivity hom, thiab infrared absorption hom; Kev kuaj pom cov pa phem muaj xws li electrochemical thiab semiconductor hom.
