Tala Fou

Muamua, o le natura o le nitrogen

Nitrogen, i lalo o tulaga masani, e leai se lanu, leai se tofo, leai se manogi ma e masani lava e le oona. E 78.12% le aofa'i o le ea (vaega vaega). I le vevela masani, o se kesi. I le mamafa o le ea masani, e avea ma vai e leai se lanu pe a faʻamafanafana i le -195.8 ℃. A mālūlū i le -209.86 ℃, o le a avea le nitrogen vai ma malo pei o le kiona. Fa'aoga: fa'aogaina o vaila'au (synthetic nylon, fiber acrylic, resin synthetic, pa'u gaosia ma isi mea taua), pa'u ta'avale (e mafai e le nitrogen ona fa'aitiitia lelei le pisapisao o pa'u, fa'aumi le ola tautua o pa'u). Talu ai ona o le nitrogen e le fa'aaogaina, e masani ona fa'aaogaina e fai ma kesi puipui, e pei o le meleni, fualaau aina, mea'ai, ma le kesi fa'atumu matauila.

Lua, o le faʻaaogaina o le nitrogen

Nitrogen i metallurgy, alamanuia kemikolo, alamanuia mama, mea tau eletise ma isi matagaluega, e pei o feedstock kesi, kesi puipuia, kesi sui ma kesi faamau. E fa'aaogaina tele fo'i mea'ai fa'aisa vai, fualaau faisua ma fualaau 'aina. E faʻaaogaina lautele foi i faʻatoʻaga ma lafumanu, e pei o le teuina o saito insecticidal, teuina aisa o sua o lafumanu sili, ma isi. O le faʻavae o polotini i laʻau ma manu.

Faatasi ai ma le alualu i luma o saienisi ma tekinolosi ma le atinaʻeina o le tamaoaiga, o le faʻaogaina o le lautele o le nitrogen ua faʻalauteleina i lea aso ma lea aso.

Fa'aaoga lelei le inertia o le nitrogen

Fa'amama fa'amama u'amea: tineia susulu, fa'afefete susulu, carburizing, carbonitriding, nitriding vaivai ma isi nitrogen e fa'avae le siosiomaga vevela togafitiga o le puna o le nitrogen, u'amea ma le pa'u u'amea fa'amumu fa'agasologa o le kasa puipuiga, ma isi.

Alamanuia Metallurgical: fa'aauau le lafo, ta'avale faifaipea, uamea annealing siosiomaga puipuiga, BOF luga tuufaatasiga feula nitrogen steelmaking, steelmaking faamaufaailoga BOF, faamaufaailoga BF, BF ironmaking pulverized koale tui ma isi faiga.

Fa'aaogaina o le cryogenic liquid nitrogen

Alamanuia faaeletonika: tele-fua fa'atasi feso'ota'iga, fa'aigoa ata TV lanu, TV ma fa'amaumauga vaega ma ta'ita'i faiga gaosiga puipuiga, ma isi.

Faʻasaoina o meaʻai: meaʻai, fualaau aina (fua), fualaau faisua ma isi mea e teu ai le ea ma le faʻasaoina, aano o manufasi, sisi, sinapi, lauti ma kofe, e pei o le afifiina fou, siamu, e pei o le faʻasaoina o le oxygenation, fagu eseese o le uaina faʻamamaina ma ufiufi, ma isi.

Falema'i falema'i: vaila'au Saina (ginseng) fa'atumu fa'atumuina ma fa'asaoina, fa'atumuina o vaila'au i sisifo o le tuiina o le nitrogen, tane teu ma pusa fa'atumu o le okesene, vaila'au pneumatic felauaiga o puna ea, ma isi.

Alamanuia vailaʻau: sui, faʻamamāina, faʻamaufaʻailogaina, suʻesuʻeina o le leak ma le puipuiga o le kesi, faʻamago faʻamago, faʻafouina faʻafouina, faʻasologa o suauʻu, gaosiga o vailaʻau, ma isi.

Alamanuia Fertilizer: mea mata o le nitrogen fertilizer. Kopi puipui Catalyst, kesi fufulu, ma isi.

Alamanuia palasitika: felauaiga pneumatic o vaega palasitika, gaosiga palasitika ma le teuina oxidation puipuiga.

Alamanuia pa'u: pa'u afifiina ma teuina, pa'u gaosiga, ma isi.

Alamanuia tioata: Kesi puipuia mo le fa'a'aopo'opoga fa'agasologa o le gaosiga o tioata.

Alamanuia suauʻu: faʻatumuina o le nitrogen ma le faʻamamaina o le teuina, koneteina, fale faʻataʻitaʻi ma paipa, suʻesuʻeina o le faʻaogaina o faiga pulega, ma isi.

Atina'e suau'u i fafo: kesi e ufiufi ai suau'u i fafo, tui o le nitrogen mo le toe fa'aleleia o le suau'u, tane ma pusa inerting, ma isi.

Fa'aputuga fa'aputu: e puipuia ai le potu, fale fa'ato'aga ma isi fale teu oloa fa'amumu pefu mu ma pa, ma isi.

Va'a: suau'u tane fa'amamaina kesi, ma isi.

Tekonolosi aerospace: faʻaola suauʻu roketi, faʻamalo le kesi suitulaga ma le puipuiga o le kesi, kesi faʻatonutonu astronaut, potu faʻataʻitaʻiga avanoa, kesi faʻamama paipa vaalele vaalele, ma isi.

Isi: vali ma ufiufi nitrogen oxygenation e puipuia ai le polymerization o suauu mago, suauu ma kesi faalenatura tane teuina ma koneteina nitrogen oxygenation, ma isi.

Fa'aaogaina o le cryogenic liquid nitrogen

Vailaau fa'aalili: ta'otoga maalili, cryotherapy, fa'a'aisa toto, fa'a'aisa vaila'au ma cryopatter, ma isi.

Biomedicine: cryopreservation ma felauaiga o laau taua, sela laau, genetic germplasm, ma isi.
