Pūnaha ōrite

Hei tohu i te maha makona nui o rua tukanga matū, me te tinana, me ngā pūnaha e whakamahia ana kāwai o "wāhanga".

I roto i te māmā "wāhanga" tikanga i huaina motuhake kāwai, wahi o te pūnaha etahi, āhuatanga nei i te homogeneity whanaunga o te hanganga me te hanganga. Wāhanga, ko te tikanga ranea motuhake, me te wehea i te tahi atu wāhanga o te pūnaha i te tetahi rohe - na roto i te wāhanga interfacial.

Mai i te tirohanga o ngā pūnaha matū e ngā pūnaha ōrite taea haa wāhanga taonga i roto i tetahi āhua töpü: hau, totoka, wai, a hoki ratou ranunga me rongoā. mahi hoki te taonga noa e tetahi wahi, ko te kore e hau whakauru, wai, i tetahi o nga totoka te hanga i te wāhanga motuhake ranei. Hei tauira, ki te whakaaro tatou rite te pūnaha tauira tënei o te tio, e rewa ana me te wai, ka taea te kitea i te wāhanga e rua i roto i tenei pūnaha - wai me te tio. Ko te meka e whai ratou i te iti rawa kia kotahi, me te ake, engari i roto i te hanganga o matū rerekē, me reira tohu i te wāhanga motuhake. Waihoki, ka taea e hoatu e koe tauira o te oraraa o matū i roto i nei e taea e tatou te whakatika i te aroaro o tetahi anake wāhanga. kia hāngai ēnei ki rangi, he wai otinga o te pāhare, te waikawa pūmāota. I roto i enei pūhui, i reira he kahore wāhanga interphase kitea me i ia wāhi o tona hanganga pūnaha he ōrite.

I te wa ano, ka mea i roto i te timatanga o te whakamāramatanga tuhinga kahore he rawaka me te whānui. Kei roto te reira i te titauraa o te homogeneity me te tuakiri o te hanganga, engari he hāngai anake i roto i te faatura o ngā pūnaha taurite tenei huarahi. I roto i te take ano, ina ko te pūnaha i te āhua o te tauhohe matū, ka taea e te wāhanga e inhomogeneous. Na te rōrahi o te wāhanga ōrite e hāngai ki te āhuatanga ine whakatu i te wā i homai.

Kāwai "wāhanga" me te kaimahi rite te paearu mo te whakarōpū o ngā pūnaha tinana, me te matū. E ai ki te maha o nga pūnaha katoa e wehea ki momo pērā i te pūnaha ōrite me te pūnaha heterogeneous. Fakatatau ki he taea reira me ki te whakatakoto me te tautuhi i enei kāwai. Heterogeneous pūnahanaha Ko tetahi i roto i nei e kore e rite ki te kotahi te maha o ngā wāhanga. Na, i runga i, te pūnaha ōrite - he pūnaha i roto i i tukua kotahi anake wāhanga te.

Whakaröpütia hoki wāhanga ratou ki momo. Ko te wāhanga totoka - he kotahi i roto i nei whiwhi i tetahi wāhi ki tetahi puta i waho whiti i te wāhanga wā. Ko reira te aroaro o tenei ka āhuatanga anake tenei wāhanga e te pūnaha ōrite.

Roto i te rerekē ki tona pūnaha heterogeneous hanga te rite te wāhanga tonu me he marara, e wehewehe ai ki te maha o ngā wāhanga motuhake.

Tauira o ngā pūnaha ōrite taea e rongoā pono, no te mea te matūriki e kėia ratou, ko te ranunga e te vai i te taumata ngota.

Ko te tikanga tinana tino nui o tenei ariā faaite tenei kāwai, kia rite ki te taimau taurite o te pūnaha ōrite. Tenei tamau, i roto i te tahuri, faaite tetahi taonga nui o ngā pūnaha ōrite - toenga. Ko te tauhohe e tango i te wahi i roto i te wāhanga kotahi, tuku ki rite ōrite, e te tikanga e nga mea timatanga katoa whai wāhi i roto i reira e i roto i te āhua kotahi o te whakawhāititanga. Taurite i roto i te akoranga o taua tauhohe e āhuatanga e te taua mea rite taurite i roto i te pūnaha ōrite. Tenei te tikanga e hoki taua tauhohe puta ki te taua taumata kukū huinga e kia tonu e rua hāngai, me te whakataka tauhohe roto. huaina ana tēnei āhua ko te āhua o te taurite matū , ka ko reira, i me te nui, te kaimahi reira hei tohu mo e mutu rite taua mo te tauhohenga.

hanga te taimau taurite e taea ki te whakatau i te kaha ki te whakaoti i te tauhohenga matū i raro i etahi tikanga. Ko te uara ao, me te pā ki tetahi pūnaha.
