3A Tātari Irahiko
-
Te maroke o te waipiro i roto i te pourewa whakamātao/whakamaroke/tātari ngota karāhe tuwhera
Ko te tātari ngota 3A, e mōhiotia ana ko te tātari ngota KA, me te kōhao o te 3 angstrom, ka taea te whakamahi mō te whakamaroke i ngā hau me ngā wai me te whakamaroke i ngā warowaihā. He whānuitia hoki te whakamahinga mō te whakamaroke katoa o te penehīni, ngā hau pakaru, te ethylene, te propylene me ngā hau māori.
Ko te kaupapa mahi o ngā tātari ngota e pā ana ki te rahi o ngā pūwero o ngā tātari ngota, arā, 0.3nm/0.4nm/0.5nm. Ka taea e rātou te mimiti i ngā ngota hau he iti ake te diameter ngota i te rahi o ngā pūwero. Mēnā he nui ake te rahi o te pūwero, ka nui ake te kaha mimiti. He rerekē te rahi o ngā pūwero, ā, he rerekē anō hoki ngā mea kua tātarihia, kua wehea. I roto i ngā kupu ngāwari, ka taea anake e te tātari ngota 3a te mimiti i ngā ngota i raro i te 0.3nm, me iti iho hoki i te 0.4nm ngā ngota kua mimitihia ki te tātari ngota 4a, ā, he rite tonu te tātari ngota 5a. Ina whakamahia hei whakamaroke, ka taea e te tātari ngota te mimiti i te makuku tae atu ki te 22% o tōna ake taumaha.
