Kev Taw Qhia Txog Khoom

Nitrogen yog cov roj diatomic tsis muaj xim thiab tsis muaj ntxhiab nrog cov mis N2.
1. Ntau yam tshuaj tseem ceeb hauv kev lag luam, xws li ammonia, nitric acid, organic nitrates (propellants thiab explosives), thiab cyanides, muaj nitrogen.
2. Cov ammonia thiab nitrates uas tsim los ntawm kev siv tshuab yog cov chiv tseem ceeb hauv kev lag luam, thiab cov chiv nitrates yog cov kuab paug tseem ceeb hauv kev hloov pauv dej. Sib nrug ntawm nws txoj kev siv rau hauv cov chiv thiab cov khoom siv hluav taws xob, nitrogen yog ib qho ntawm cov organic compounds ntau yam xws li Kevlar siv rau hauv cov ntaub muaj zog thiab cyanoacrylate siv rau hauv superglue.
3. Nitrogen yog ib feem ntawm txhua pawg tshuaj loj, suav nrog cov tshuaj tua kab mob. Ntau cov tshuaj yog cov tshuaj ua piv txwv lossis cov tshuaj ua ntej ntawm cov tshuaj uas muaj nitrogen: piv txwv li, cov organic nitrates nitroglycerin thiab nitroprusside tswj cov ntshav siab los ntawm kev hloov pauv mus ua nitric oxide.
4. Ntau yam tshuaj uas muaj nitrogen, xws li cov caffeine thiab morphine ntuj lossis cov amphetamines tsim, ua haujlwm rau cov receptors ntawm cov tsiaj neurotransmitters.

Daim Ntawv Thov

1. Cov Pa Nitrogen:
Cov thoob dej nitrogen kuj tseem hloov cov pa roj carbon dioxide ua lub zog tseem ceeb rau cov phom paintball.
Hauv ntau yam kev siv tshuab ntsuas: Cov roj nqa rau cov roj chromatography, cov roj txhawb nqa rau Electron Capture Detectors, Liquid Chromatography Mass Spectrometry, cov roj ntxuav rau Inductive Couple Plasma.

Khoom siv

(1) Txhawm rau sau cov teeb.
(2) Hauv cov huab cua antibacterial thiab cov cuab yeej sib xyaw rau kev siv tshuaj lom neeg.
(3) Ua ib feem ntawm Cov Khoom Siv Tswj Huab Cua thiab Cov Khoom Siv Hloov Kho Huab Cua, cov roj sib xyaw rau cov txheej txheem saib xyuas ib puag ncig, cov roj laser sib xyaw.
(4) Yuav kom inert ntau yam tshuaj tshuag qhuav ntau yam khoom lossis cov ntaub ntawv.

Nitrogen siv tau los ua ib qho hloov pauv, lossis ua ke nrog, carbon dioxide los ua kom cov kegs ntawm qee cov npias, tshwj xeeb tshaj yog stouts thiab British ales, vim yog cov npuas me me uas nws tsim tawm, uas ua rau cov npias faib tawm du thiab zoo dua.

2. Cov kua nitrogen:
Ib yam li dej khov qhuav, kev siv cov kua nitrogen tseem ceeb yog ua cov khoom siv txias.

Ntim & Xa Khoom

Cov kev ntsuas kev pab thawj zaug

Kev ua pa: Tshem tawm mus rau qhov chaw uas muaj huab cua ntshiab thiab ua kom yooj yim rau kev ua pa. Yog tias ua pa nyuaj, muab oxygen. Yog tias ua pa tsis tau lawm, muab kev ua pa cuav. Nrhiav kev kho mob tam sim ntawd.
Kev sib chwv ntawm daim tawv nqaij: Tsis muaj nyob rau hauv kev siv li niaj zaus. Hu rau kuv tus kws kho mob yog tias muaj cov tsos mob tshwm sim.
Kev sib cuag qhov muag: Tsis muaj dab tsi thaum siv li niaj zaus. Hu rau kuv yog tias muaj cov tsos mob tshwm sim.
Kev Noj Haus: Tsis yog txoj kev xav tau ntawm kev raug mob.
Kev tiv thaiv tus kheej ntawm tus neeg pab thawj zaug: cov neeg ua haujlwm cawm neeg yuav tsum muaj cov khoom siv ua pa uas muaj peev xwm ua tau.
