Ngā Tauira Pātai me te Kōrero mō ngā Momo Colloids
Pendahuluan
He pūnaha te kōroiti e rua ngā wāhanga: he wāhanga marara me te wāhanga marara. Ko te wāhanga marara ko ngā matūriki he rahi kōroiti (1-1000 nm), ko te wāhanga marara ia te reo e marara ai ngā matūriki. He maha ngā wā ka kitea ngā kōroiti i roto i te oranga o ia rā, ā, ka akohia i roto i te matū nā te mea he āhuatanga ahurei ō rātou e wehewehe ana i a rātou mai i ngā otinga me ngā whakatārewatanga tūturu. I roto i tēnei tuhinga, ka matapakihia e mātou ētahi momo kōroiti i runga i ō rātou wāhanga marara me te marara, me ngā tauira raruraru me ngā kōrero hei whakamārama i tēnei ariā.
