He aha te Peera Pāmahana-Iti
Kāore te peera pāmahana-iti e pā ana ki tētahi peera e mahi pūmau ana i roto i ngā taiao pāmahana-tiketike (he rerekē kingā peera pāmahana teitei), engari he peera i hangaia ki ngā rauemi motuhake me ngā hoahoa hanganga hei whakaiti i te tauwehenga waku, kia iti ai te wera waku. Mā tēnei ka taea e te peera te pupuri i te pāmahana iti ahakoa te roa o te whakamahinga.
Ngā peeraKo ngā mea kei raro iho i te -60℃ te pāmahana mahi e kiia ana he peera pāmahana-iti. E whakamahia nuitia ana ēnei i roto i ngā papu wai maha, pērā i ngā papu hau māori wairewa, ngā papu hauota wai (hauwai, hāora), ngā papu butane, ngā papu wai mō ngā rōkete me ngā pere, ngā waka rererangi, me ētahi atu.
Te Pāmahana Whakahaere o ngā Peera Pāmahana-Iti
Ko te pāmahana whakahaere o te peera pāmahana-iti e whakaata ana i te hangarau rauemi me te taumata hanga o te peera. Ko te nuinga o te wā ka inehia e te rerekētanga pāmahana i waenga i te mowhiti o waho o te peera me te hinu whakamatao i werohia i te wā e whakahaerehia ana. Ko te tikanga o te pāmahana whakahaere iti ake he roa ake te roa o te oranga o te peera me te pai ake o te mahi.
Ngā Kāwai o ngā Peera Pāmahana-Iti
Ko ngā peera pāmahana iti he maha ngā peera pōro hohonu rarangi kotahi me ngā peera roera porotaka.
Mōngā peeraI te mea ka pāngia te pūngao e te hopukanga i ngā pāmahana iti, ko te āhuatanga o waho ko te huringa pāmahana, ko te āhuatanga o roto ko ngā tauwehenga whānui wera rerekē o te pou, te anga, me ngā rauemi. Ina nui te awhe pāmahana, ka mimiti ngā rauemi rerekē i ngā tere rerekē, ka whakaiti i te ātea me te aukati. Nō reira, mō ngā taputapu he whānui te awhe mahi, tae atu ki ngā taputapu e whakamahia ana i ngā pāmahana iti, me tatau ngā tauwehenga whānui o ngā rauemi, ā, ki te taea, whakamahia ngā rauemi he rite ngā tauwehenga whānui mō ngā hua pai ake.
Hei tāpiritanga, i roto i te hoahoa hanganga, he mea tika kia kaua e whakamahia he peera roera kōniko i ia pito o te pou. I roto i tēnei hanganga, ko te roa o te tawhiti i waenga i ngā peera e rua, ko te nui ake o te tūponotanga o te piri. Mena ka tāutahia he takirua peera whakarara ki tetahi pito o te pou, ka taea e rātou te mahi hei tūnga pou, hei aukati i te nekehanga tuaka. Ko tetahi atu pito o te pou, e whakamahia ana me te peera hurihuri, ka aukati noa i ngā kaha radial, ka taea te whakawhāiti i te nekehanga tuaka me ngā huringa pāmahana tuaka.
Kōwhiringa Rauemi mō ngā Peera Pāmahana-Iti
Te Kōwhiringa o te Rino Peihana mō ngā Peihana Pāmahana-Iti
He maha ngā wā ka hangaia ngā peera pāmahana-iti ki ngā maitai peera kowiri tira 9Cr18, 9Cr18Mo rānei, ā, ka taea hoki te hanga mai i te parahi beryllium, te uku, me ētahi atu rauemi. I raro i ngā pāmahana mahi tino iti (te pāmahana tino -253℃), ki te hiahiatia te rohe mahi -253℃, ka taea te whiriwhiri i te rauemi 6Cr14Mo engari me whakamahi i roto i te taiao korehau.
I te wā e whakamahia ana ngā peera pāmahana-iti, me aro atu ki ngā take pēnei i te wera nui e hua mai ana i te korenga o te hinu whakahinuhinu, nō reira he mea nui te whiriwhiri i ngā hinu whakahinuhinu e tika ana.
