Tirohia te whiti i raro nei, ka whakahoki i te pātai i muri i roto i te reo ano rite te whiti: Passage: 2H, te atu pūmau isotope hauwai, e mohiotia ana ko te deuterium, me te kei roto i te kotahi proton, me te kotahi neutron i roto i te karihi. whakaaro te deuterium katoa i roto i te ao kua whakaputaina i te wa o te Big Bang, a kua roa mai i taua wa. e kore te deuterium he irirangi, a kahore e tohu i te mōrea kino nui. wai whakapakari i roto i te rāpoi ngota e ngā deuterium hei utu o te hauwai noa e kiia wai taimaha. whakamahia te deuterium me ona pūhui rite te tapanga kore-radioactive i roto i ngā whakamātautau matū, me i roto i ngā rongoā mō te 1H-NMR spectroscopy. whakamahia te wai taimaha rite te moderator neutron me te coolant mō ngā pūkaha karihi. Deuterium Ko hoki te pūmanawa arumoni mō te pūngao whakakotahitanga karihi.
Ko te 2H
