Khoom Taw Qhia
Nitrogen yog cov roj tsis muaj xim thiab tsw ntxhiab diatomic nrog cov qauv N2.
1.Muaj ntau yam tseem ceeb hauv kev lag luam, xws li ammonia, nitric acid, organic nitrates (propellants thiab explosives), thiab cyanides, muaj nitrogen.
2.Synthetically tsim ammonia thiab nitrates yog cov tseem ceeb muaj fertilisers, thiab chiv nitrates yog cov pa phem tseem ceeb nyob rau hauv lub eutrophication ntawm cov dej systems.Apart from nws siv nyob rau hauv chiv thiab lub zog-khoom, nitrogen yog ib tug constituent ntawm organic tebchaw raws li ntau haiv neeg li Kevlar siv nyob rau hauv siab. -lub zog ntaub thiab cyanoacrylate siv hauv superglue.
3.Nitrogen yog ib qho tseem ceeb ntawm txhua chav tshuaj tshuaj loj, suav nrog tshuaj tua kab mob. Ntau cov tshuaj yog cov khoom siv los yog cov khoom siv ntawm lub cev muaj zog nitrogen-muaj cov teeb liab molecules: piv txwv li, cov organic nitrates nitroglycerin thiab nitroprusside tswj ntshav siab los ntawm metabolizing rau nitric oxide.
4.Muaj ntau yam tshuaj uas muaj nitrogen, xws li tej yam ntuj tso caffeine thiab morphine los yog hluavtaws amphetamines, ua rau receptors ntawm tsiaj neurotransmitters.
Daim ntawv thov
1. Nitrogen Gas:
Nitrogen tso tsheb hlau luam kuj tseem hloov cov pa roj carbon dioxide ua lub zog loj rau cov phom pleev xim.
Hauv ntau daim ntawv thov kev tshuaj ntsuam xyuas: Cov khoom siv roj rau cov roj chromatography, txhawb nqa roj rau Electron Capture Detectors, Liquid Chromatography Mass Spectrometry, ntxuav roj rau Inductive Couple Plasma.
Khoom siv
(1) Txhawm rau sau cov qij.
(2) Hauv cov huab cua tiv thaiv kab mob thiab cov cuab yeej sib xyaw rau kev siv tshuaj lom neeg.
(3) Raws li cov khoom siv hauv Cov Txheej Txheem Txheej Txheem Ntim thiab Hloov Kho Cov Ntawv Sau Cov Ntawv Sau, cov roj sib xyaw ua ke rau kev soj ntsuam ib puag ncig, cov roj laser sib xyaw.
(4) Txhawm rau inert ntau cov tshuaj tiv thaiv kom qhuav ntau yam khoom lossis khoom siv.
Nitrogen tuaj yeem siv los hloov, lossis ua ke nrog, cov pa roj carbon dioxide txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm
2. Cov kua nitrogen:
Zoo li cov dej khov qhuav, kev siv cov kua nitrogen tseem ceeb yog ua cov tub yees.

Kev pab thawj zaug
Inhalation: Tshem tawm mus rau huab cua ntshiab thiab ua pa kom xis nyob. Yog ua pa nyuaj, muab cov pa oxygen. Yog tias ua tsis taus pa lawm, muab kev ua pa tawm dag zog. Tau txais kev kho mob tam sim ntawd.
Kev sib cuag ntawm daim tawv nqaij: Tsis muaj nyob rau hauv ib txwm siv. Ua rau kuv saib xyuas yog tias muaj tsos mob tshwm sim.
Kev sib cuag qhov muag: Tsis muaj nyob rau hauv ib txwm siv. Ua rau kuv saib xyuas yog tias muaj cov tsos mob tshwm sim.
Kev Noj Qab Haus Huv: Tsis yog txoj kev xav tau ntawm qhov raug.
Kev tiv thaiv tus kheej ntawm thawj tus neeg pab: cov neeg ua haujlwm cawm siav yuav tsum tau nruab nrog tus kheej cov khoom siv brea khoom.
