Me pēhea te manatoko i te manatoko i te ihirangi o te Scandium (Sc) o ngā mata o te tāhūpa?
Ko te hanganga huānga te mea e whakatau tika ana i te kaha miihini o te mata o te tāpine, te ātete ki te waikura, me te manawanui ki te wera. Ka whakawhirinaki ngā superalloys ki ngā ōwehenga tika o te nikara, te konupora, me te konupora mō te hanganga pumau i raro i te 1,000°C. Ko ngā rerekētanga he iti iho i te ±0.1% i roto i te whakarewa ...Pānuihia atu -
He aha te take e tika ai te whakamātautau scandium mā te whakamahi i te EDXRF ringaringa i ngā wāhanga e haere mai ana?
Mā te tirotiro i ngā wāhanga e haere mai ana ka kitea ngā hapa, ā, ka ārai i te mahi anō utu nui mā te manatoko i ngā āhuatanga o te koranu konumohe scandium i mua i te taenga atu o ngā wāhanga ki te hanga. Ka pā tika te hanganga koranu hē ki te mahi a te hua, ka piki ake ngā reiti hapa, ā, ka arahi ki te hekenga...Pānuihia atu -
Ka taea e te X-ray Fluorescence Spectroscopy te ine tika i te konupūmā me te phosphorus i roto i ngā whāngai manu?
Neke atu i te 70% o te katoa o ngā kohuke i roto i ngā angaanga manu ko te konupūmā me te whākōkī, ā, koinei te pūtake o te hydroxyapatite e tika ana mō te pakari me te kaha o te wheua. He pai te konupūmā i roto i te whāngai manu mō te whanaketanga o te angaanga, me te ārai i ngā mate pēnei i te rickets me te os...Pānuihia atu -
