Hauota (N2)

Ngā tawhā hangarau

Ko te hauota (N2) te wāhanga nui o te āhuarangi o te ao, e 78.08% o te katoa. He hau kore tae, kore kakara, kore reka, kore paitini, ā, tata korekore rawa. Kāore te hauota e mura, ā, e kiia ana he hau whakamomori (arā, mā te manawa i te hauota parakore ka kore te tinana tangata i te hāora). Kāore te hauota e mahi matū. Ka taea e ia te tauhohe ki te hauwai hei hanga haukini i raro i te pāmahana teitei, te pēhanga teitei me ngā āhuatanga whakakorikori; ka taea e ia te hono atu ki te hāora hei hanga waikura hauota i raro i ngā āhuatanga tukunga. He maha ngā wā e kiia ana te hauota he hau korekore. Ka whakamahia i roto i ētahi āhuarangi korekore mō te maimoatanga whakarewa me ngā pūangi hei ārai i te arc, engari ehara i te mea korekore matū. He huānga nui i roto i te oranga o ngā tipu me ngā kararehe, ā, he wāhanga o te maha o ngā matū whai hua. Ka honoa te hauota ki te maha o ngā konganuku hei hanga nitrides mārō, ka taea te whakamahi hei konganuku ātete-kakahu. Mā te iti o te hauota i roto i te maitai ka aukati i te tipu o te witi i ngā pāmahana teitei, ā, ka whakanui ake hoki i te kaha o ētahi maitai. Ka taea hoki te whakamahi hei hanga mata mārō i runga i te maitai. Ka taea te whakamahi i te hauota hei hanga haukini, waikawa hauota, nitrate, cyanide, me ētahi atu; hei hanga i ngā mea pahū; hei whakakī i ngā inemahana pāmahana teitei, i ngā pūangi mura; hei hanga rauemi kore mahi hei tiaki i ngā rauemi, hei whakamahi i roto i ngā pouaka whakamaroke, i ngā putea karapu rānei. Hauota wai i te wā e whakatio ana i ngā kai; hei whakamatao i roto i te taiwhanga. Me penapena poutū te hauota ki tētahi wāhi hauhautanga pai, haumaru, ā, kāore e pāngia e te huarere, ā, kaua te pāmahana rokiroki e neke ake i te 52°C. Kaua he rauemi mura i roto i te wāhi rokiroki, ā, me waiho kia matara atu i ngā wāhi tomo me ngā wāhi putanga ohorere, ā, kaua hoki he tote, he rauemi waikura rānei. Mō ngā rango hau kāore i whakamahia, me hiri pai te taupoki takirere me te takirere putanga, ā, me penapena motuhake ngā rango kau mai i ngā rango kī. Āraia te rokiroki nui rawa me te wā rokiroki roa, me pupuri hoki i ngā tuhinga rokiroki pai.

Taupānga:

①I roto i ngā momo whakamahinga taputapu tātari:

Hau kawe mō te chromatography hau, hau tautoko mō ngā Pūoko Hopu Irahiko, Chromatography Wai Spectrometry Papatipu, hau pure mō te Ira Plasma Takirua Ārai.

②Rauemi:

1. Hei whakakī i ngā pūangi rama.
2. I roto i te āhuarangi huakita me ngā ranunga taputapu mō ngā tono koiora.
3. Hei wāhanga i roto i ngā tono Tākai Āhuarangi Whakahaere me ngā tono Tākai Āhuarangi Whakarerekētia, 4. Te whakatikatika i ngā ranunga hau mō ngā pūnaha aroturuki taiao, ngā ranunga hau taiaho.
5. Hei ārai i ngā tauhohenga matū maha, whakamarokehia ngā hua, ngā rauemi rānei.

③Hauota wai:

Pērā i te huka maroke, ko te whakamahinga matua o te hauota wai he mea hei whakamatao.

Mōkihi noa:
