Mā te tāpiritanga o te kariuma ka whakau i te wāhanga δ o te plutonium i te pāmahana rūma, ka taea ai te whakapai ake i ngā āhuatanga miihini e tika ana mō ngā tono karihi. Ki te kore he kariuma, ka neke te plutonium ki ngā wāhanga α-, β-, me te γ-pakaru. Mā te whakakotahitanga me te 1–2 wt% kariuma ka ārai i ngā huringa wāhanga kāore e hiahiatia, ā, ka tautoko i te whakarewanga, te whakarewanga, me te miihini whakahaeretia. Mā te wāhanga δ kua whakau ka whakaiti i te whānui o te rōrahi, ka whakaiti i te mōrearea pakaru, ā, ka pupuri i te haumaru i roto i te hanganga koranu kariuma kariuma kariuma mō ngā poka nui me ngā rauemi tauhohenga. Ko te whakakotahitanga te mea nui ki ngā tono koranu kariuma kariuma kariuma, tae atu ki te hanga wahie karihi roa.
TE KĀRIUMA I NGĀ TAUIRA TOE MAROKE

Ngā Wero i roto i te Ine i te Plutonium Gallium Alloy
Te Tukatuka Whakarewa me te Whakaputa Toenga
Ko te hanga i te ingota plutonium ka whakauru i te whakaiti waikura, te tango tote, me te whakamahine hiko. Ka puta mai i ēnei mahi he toenga maroke kei roto he gallium toenga e hiahia ana kia inehia mō te manatoko kounga koranu me te tirotiro ture. Ko ngā toenga noa he matrices matotoru, he maha ngā wā ka neke atu i te 18 g/cm³, e whakaata ana i ngā whakawhiti matotoru i waenga i ngā allotropes plutonium me ngā wāhanga whakakotahi. Ko te uauatanga matū o ēnei toenga i ahu mai i te taurite maha-wāhanga, te kawe tote, me te hekenga actinide, inā koa i muri i ngā tāpiringa gallium tika. Ko ngā huringa tango tote, e uru ana ki te Mg, Ca, ngā konganuku alkali rānei, ka whakauru i ngā huānga e uaua ai te kimi gallium. Ka purea e te whakamahine hiko te ingota engari ka waiho ngā toenga gallium kukū, e hiahia ana kia tika te tātari. Ko te ine gallium tika ka whakamōhio i te whakaae puranga me te aukati i ngā rerekētanga kounga i roto i te rauemi kua whakapumautia te wāhanga δ.
Ka pāngia te aromatawai toenga e ngā pānga o te plutonium, te uranium, me ngā tote tukatuka, ka pāngia ia e te kōtaha tukunga o te gallium. He mea nui ngā tikanga tairongo nui me ngā tikanga tino whiriwhiri, pērā i ngā tātaritanga Lonnmeter XRF.
Tikanga XRF: Ngā Mātāpono me ngā Painga
Ariā XRF Taketake

Mā te whakamātautau kore-whakangaro ka tiakina te pono o te hanganga me te whakakore i te ngaronga o te tauira, he mea nui mō ngā totoka irahiko. Ka whakawhāitihia e te XRF te whakaaturanga a te kaiwhakahaere mā te kaha ine mamao, inā koa i roto i te aromatawai toenga konganuku plutonium.
Ngā Āhuatanga o te Kaitātari Kariuma XRF
Te Mita Rorohiko XRFgāruma Ka whakamahia e te tātari he pūoko nekeneke silicon taumira teitei mō te wehewehe i ngā hihi matawhānui. Ka tautuhi tika i ngā tihi gallium Kα me Kβ ahakoa ngā tohu fluorescence plutonium e taupatupatu ana. Kua hangaia te tātari mō te ine tere, haumaru hoki o te gallium i roto i ngā tauira totoka.
Te Whakamahinga i roto i ngā Rerenga Mahi o te Plutonium Gallium Alloy
Ka tukuna e te Lonnmeter XRF ngā inenga gallium tika i muri tonu i te whakakotahitanga me te aromatawai toenga. Ka taea te urupare tere i te tukanga—he mea nui mō te whakahaere i te hanganga koranu gallium plutonium me te pumau o te āhua. Ka tere te tautuhi a te XRF i ngā taumata gallium matua i ngā pūwāhi whakahaere nui, ka tere ake te whakaputa me te hangarua i ngā huringa hangarua mō ngā rauemi karihi. Ka tautokohia e te rerenga mahi ngā tuhinga ture me te arotautanga tukanga i roto i te whakarewa plutonium.

Ngā Pātai Auau
He aha te hiranga o te gallium i roto i ngā koranu plutonium?
Ka whakaū te kariuma i te wāhanga-δ o te konganuku plutonium, ka ārai i te hurihanga ki te wāhanga-α pakarukaru, ā, ka whakarite i te ngāwari i te pāmahana rūma. Mā te 2–4 i te% kariuma ka whānui ake te mara wāhanga-δ, ka taea ai te hanga i ngā koranu kariuma plutonium ka taea te miihini e tika ana mō te hanga wāhanga karihi me te pono o te rokiroki mō te wā roa. Ka whakarerekē te kariuma i te hanganga hiko o Pu, ka whakaiti i te taumahatanga whatunga, ka whakaroa i te hurihanga wāhanga, ka hanga i ngā koranu wāhanga-δ kia haumaru ake, kia kaha ake hoki te miihini mō ngā tono karihi.
Me pēhea te tātaritanga a XRF i te gallium i roto i ngā toenga plutonium matatini?
Mā te ine ira-X ka whakamahia ngā tihi tukunga gallium motuhake-huānga (Kα=9.25 keV), ka wehewehea rātou mai i ngā rārangi plutonium i roto i ngā matrices maha-huānga. Ka tukuna e te tikanga he tātari tika, kore-whakangaro o ngā toenga totoka maroke i muri i te whakarewatanga, ka hinga i ngā pānga matrix mai i ngā actinides taumaha mā te whakamahi i te wetewete ira matatau me te whakatikatika matrix.
