Ngā āhuatanga motuhake o te waea ātete Karma

1) I tīmata mā te waea wera hiko Nickel Chromium Akomanga 1, i whakakapia ētahi o ngā Ni ki
Al me ētahi atu huānga, ā, nō reira i tutuki ai he rauemi ātete tino tika me te whakapai ake
te tauwehenga pāmahana ātete me te kaha hiko wera ki te parahi.
Mā te tāpiri o te Al, kua angitu mātou ki te whakanui ake i te ātete rōrahi ki te 1.2 ngā wā.
i te waea wera hiko Nickel Chromium Akomanga 1, ā, ko tōna kaha kume he 1.3 ngā wā te nui ake.

2) He tino iti te tauwehenga pāmahana tuarua β o te waea Karmalloy KMW, - 0.03 × 10-6/ K2,
ā, ko te pihi pāmahana ātete ka tata rite ki te rārangi tika i roto i te whānui
awhe pāmahana.

Nō reira, ko te tauwehenga pāmahana kua whakatakotoria hei tauwehenga pāmahana toharite i waenga i
23 ~ 53 °C, engari 1 × 10-6/K, ko te tauwehenga pāmahana toharite i waenga i te 0 ~ 100 °C, tera pea
kia whakamahia mō te tauwehenga pāmahana.

3) He iti hoki te kaha hikohiko ki te parahi i waenga i te 1 ~ 100 °C, i raro iho i te + 2 μV/K, ā,
he tino pumau te āhua mō ngā tau maha.

4) Mena ka whakamahia tēnei hei rauemi ātete ki te tino tika, ka whakamahia te maimoatanga wera pāmahana iti
e hiahiatia ana hei whakakore i ngā hapa tukatuka, pērā i te waea Manganin CMW.
