whakaahuatanga hua
Ko te wai taumaha (deuterium oxide) he ahua o te wai ko ona ngota hauwai he deuterium (2H, D ranei, e kiia ana ko te hauwai taumaha) kaua ko te hauwai-1 isotope noa (1H, ka kiia ko te protium) e hanga ana i te nuinga o te hauwai. i roto i te wai noa.Ko te noho mai o te wetewete taumaha he rerekee nga ahuatanga karihi o te wai, a, ko te pikinga o te papatipu he paku rereke nga ahuatanga o te tinana me te matū ina whakaritea ki te wai noa.
Ko te Deuterium he hauwai taumaha. Kei roto i te wai taumaha nga ngota deuterium ka whakamahia i roto i nga reactors karihi. Ko te wai Semiheavy (HDO) he mea noa ake i te wai taumaha parakore, engari he kikokore te wai taumaha-hauora engari kaore he ahuatanga motuhake. He reo irirangi te wai tritiated i runga i te ihirangi tritium.
He rereke nga ahuatanga o te wai taumaha mai i te wai auau, penei i te 10.6% te matotoru me te teitei ake o te rewa. Ko te wai taumaha he iti ake te wehewehe i te pāmahana kua whakaritea, karekau he tae kikorangi o te wai auau. Ahakoa kaore he rereketanga o te reka, he paku reka te reka. Ko te wai taumaha ka pa ki nga punaha koiora ma te whakarereke i nga whākōkī, te here hauwai, me te wehenga pūtau i roto i te eukaryotes. Ka taea te whakamate ki nga rauropi multicellular i runga i te 50%. Heoi, ka ora etahi prokaryotes penei i te huakita i roto i te taiao hauwai taumaha. Ko te wai taumaha he paitini ki te tangata, engari he nui te nui e hiahiatia ana kia puta te paihana.
