Ko te tauwehenga whānui rārangi o te karāhe kei te 5.5-7.5x10 - ⁶/℃. Heoi, mō ngā momo karāhe rerekē, ka rerekē pea tōna tauwehenga whānui.
He pai te pumau o te karāneti i te pāmahana, e whakaatuhia ana i roto i ngā āhuatanga e whai ake nei:
Te iti o te whakarerekētanga wera: nā te iti o te tauwehenga whānui, he iti noa te whakarerekētanga wera o te karāhe ina rerekē te pāmahana. Mā tēnei ka taea e ngā wāhanga karāhe te pupuri i te rahi me te āhua pumau i roto i ngā taiao pāmahana rerekē, he mea pai hei whakarite i te tika o ngā taputapu tino tika. Hei tauira, i roto i ngā taputapu ine tino tika, te whakamahi i te karāhe hei turanga, hei papa mahi rānei, ahakoa he rerekētanga te pāmahana o te taiao, ka taea te whakahaere i te whakarerekētanga wera i roto i te whānuitanga iti, kia tika ai ngā hua ine.
He ātete pai ki ngā ru wera: Ka taea e te karāneti te tu atu i tētahi taumata o ngā huringa pāmahana tere me te kore e kitea he pakaru, he pakaru rānei. Nā te mea he pai te kawe wera me te kaha wera, ka taea te whakawhiti wera tere me te ōrite ina huri te pāmahana, ka whakaiti i te kukū ahotea wera o roto. Hei tauira, i roto i ētahi taiao whakaputa ahumahi, ina tīmata ohorere, ina mutu rānei te mahi a te taputapu, ka tere te huri o te pāmahana, ā, ka taea e ngā wāhanga karāneti te urutau pai ake ki tēnei ru wera me te pupuri i te pumau o tā rātou mahi.
He pumau roa: Whai muri i te wā roa o te koroheketanga taiao me te mahi whenua, kua tukuna te ahotea o roto o te karāhe, ā, kua pumau te hanganga. I roto i te tukanga whakamahinga roa, ahakoa i muri i ngā huringa maha o te huringa pāmahana, ehara i te mea ngāwari te whakarerekē i tōna hanganga o roto, ka taea tonu te pupuri i te pumau pāmahana pai, ka whakarato tautoko pono mō ngā taputapu tino tika.
Ki te whakatauritea ki ētahi atu rauemi noa, he teitei ake te pumau o te karāneti i te wera, koinei te whakataurite i waenga i te karāneti me ngā rauemi whakarewa, ngā rauemi uku, ngā rauemi hiato i runga i te pumau o te wera:
Ki te whakataurite ki ngā rauemi whakarewa:
He nui te tauwehenga whānui o ngā rauemi whakarewa whānui. Hei tauira, ko te tauwehenga whānui raina o te maitai waro noa he tata ki te 10-12x10 - ⁶/℃, ā, ko te tauwehenga whānui raina o te koranu konumohe he tata ki te 20-25x10 - ⁶/℃, he nui ake i te karāneti. Ko te tikanga tēnei, ina huri te pāmahana, ka nui ake te hurihanga o te rahi o te rauemi whakarewa, ā, he ngāwari ki te whakaputa i te ahotea ā-roto nui ake nā te whānui wera me te whakahekenga makariri, ka pā ki tōna tika me tōna pumau. Ka iti ake te hurihanga o te rahi o te karāneti ina rerekē te pāmahana, ka pai ake te pupuri i te āhua me te tika taketake. He teitei te kawe wera o ngā rauemi whakarewa, ā, i roto i te tukanga whakamahana tere, whakamatao rānei, ka tere te kawe i te wera, ka hua ake he rerekētanga pāmahana nui i waenga i te roto me te mata o te rauemi, ka hua ake he ahotea wera. He rerekē, he iti te kawe wera o te karāneti, ā, he puhoi te kawe wera, ka taea te whakaiti i te whakaputanga o te ahotea wera ki tētahi taumata me te whakaatu i te pumau wera pai ake.
Ki te whakataurite ki ngā rauemi uku:
Ka tino iti te tauwehenga whānui wera o ētahi rauemi uku mahi-teitei, pērā i ngā uku silicon nitride, ko tōna tauwehenga whānui raina he tata ki te 2.5-3.5x10 - ⁶/℃, he iti iho i te karāneti, ā, he painga anō hoki tōna mō te pumau wera. Heoi, he pakarukaru ngā rauemi uku, he ngoikore te ātete ki te ru wera, ā, he ngāwari te pakaru, te pakaru rānei ina huri tere te pāmahana. Ahakoa he paku teitei ake te tauwehenga whānui wera o te karāneti i ētahi uku motuhake, he pai tōna pakari me tōna ātete ki te ru wera, ka taea te tu atu i tētahi taumata o te whakarerekētanga pāmahana, i roto i ngā tono mahi, mō te nuinga o ngā taiao huringa pāmahana kāore i te tino nui, ka taea e te pumau wera o te karāneti te whakatutuki i ngā whakaritenga, ā, he taurite ake tana mahi whānui, he iti ake te utu.
Ki te whakataurite ki ngā rauemi hiato:
Ka taea e ētahi rauemi hiato matatau te whakatutuki i te tauwehenga iti o te whakawhānui wera me te pumau wera pai mā te hoahoa whaitake o te whakakotahitanga o te muka me te matihiko. Hei tauira, ka taea te whakarite i te tauwehenga whakawhānui wera o ngā hiato whakakaha muka waro kia rite ki te ahunga me te ihirangi o te muka, ā, ka taea te eke ki ngā uara tino iti i ētahi ahunga. Heoi, he uaua te tukanga whakarite o ngā rauemi hiato, ā, he nui te utu. Hei rauemi taiao, kāore e hiahiatia he tukanga whakarite uaua mō te karāhe, ā, he iti te utu. Ahakoa kāore pea i te rite te pai ki ētahi rauemi hiato teitei i roto i ētahi tohu o te pumau wera, he painga kei a ia i runga i te mahi utu, nō reira he whānuitia te whakamahinga i roto i te maha o ngā tono tuku iho he whakaritenga mō te pumau wera. I roto i ngā ahumahi hea e whakamahia ai ngā wāhanga karāhe, ko te pumau pāmahana te whakaaro nui? Homai ētahi raraunga whakamātautau motuhake, ētahi tauira rānei o te pumau wera karāhe. He aha ngā rerekētanga i waenga i ngā momo pumau wera karāhe rerekē?
