He taputapu tohutoro tika nui ngā wāhanga miihini karāhe, e whakamahia whānuitia ana i roto i ngā mahi tirotiro ine me te ine taiwhanga. Ka taea te whakarite i ō rātou mata ki ngā kōhao me ngā awaawa rerekē—pērā i ngā kōhao-roto, ngā mokowā-T, ngā awaawa-U, ngā kōhao miro, me ngā kōhao mokowā—kia tino urutau ai mō ngā whakatakotoranga miihini rerekē. Ko ēnei turanga karāhe kua whakaritea, kāore i te rite te āhua, e kiia ana ko ngā hanganga karāhe, ko ngā wāhanga karāhe rānei.
Neke atu i te tekau tau o te wheako whakaputa, kua whakatūria e tā mātou kamupene he ingoa pakari i roto i te hoahoa, te hanga, me te whakahou i ngā wāhanga miihini karāhe. Ina koa, e whakawhirinakihia ana ā mātou otinga e ngā rāngai tino tika pēnei i ngā taiwhanga ine me ngā tari whakahaere kounga, e hiahiatia ana te tino tika. Ka tutuki tonu, ka hipa rānei ā mātou hua i ngā paerewa manawanui nā te whiriwhiri rauemi pumau me te whakahaere kounga tino pakari.
He mea hanga ngā wāhanga mīhini karāneti mai i te kōhatu tūturu i hangaia mō ngā miriona tau, ā, he tino pai te pumau o te hanganga. Kāore e pāngia te tika o te hanganga e ngā rerekētanga pāmahana. E ai ki ngā paerewa Hainamana, ka whakarōpūtia ngā wāhanga mīhini karāneti ki te Wāhanga 0, Wāhanga 1, me te Wāhanga 2, i runga i te tika e hiahiatia ana.
Ngā Whakamahinga me ngā Āhuatanga Noa
Te Whakamahinga Ahumahi Whānui
He whānuitia te whakamahinga o ngā wāhanga miihini karāneti puta noa i ngā ahumahi pēnei i te hikohiko, te motuka, te mīhini, te rererangi, me te hanga tino tika. He maha ngā kaihoahoa e pai ake ana ki a rātou i ngā pereti rino maka tuku iho nā te mea he pai ake te pumau o te wera me te ātete ki te kakahu. Mā te whakauru i ngā mokamoka-T, i ngā poka tino tika rānei ki te turanga karāneti, ka whānui ake te whānuitanga o ngā tono—mai i ngā papa tirotiro ki ngā wāhanga turanga mīhini.
Ngā Whakaaroaro mō te Tika me te Taiao
Ko te taumata o te tika e whakatau ana i te taiao mahi. Hei tauira, ka taea e ngā waeine Taumata 1 te mahi i raro i te pāmahana rūma paerewa, ko ngā waeine Taumata 0 ia me whai taiao e whakahaerehia ana te āhuarangi me te whakatikatika i mua i te whakamahinga kia mau tonu ai te tika o te ine.
Ngā Rerekētanga Rauemi
He rerekē te karāhe e whakamahia ana i roto i ngā wāhanga tino tika i te karāhe whare whakapaipai.
Karati tino tika: Te mātotoru o te 2.9–3.1 karamu/cm³
Karaehe whakapaipai: Te mātotoru o te 2.6–2.8 karamu/cm³
Raina whakapakari (hei whakatairite): 2.4–2.5 karamu/cm³
Tauira: Papa Whakatere Hau Granite
I roto i ngā tono teitei, ka honoa ngā papa granite me ngā pūnaha kawe hau hei hanga papa ine hau-mānu. Ka whakamahia e ēnei pūnaha ngā peera hau pūwero kua tāutahia ki runga i ngā reera granite tika hei whakahohe i te nekehanga kore-waku, he mea pai mō ngā pūnaha ine gantry tuaka-rua. Hei whakatutuki i te tino papatahi e hiahiatia ana, ka maha ngā huringa o te whiri me te whakakanapa tika i ngā mata granite, me te aroturuki tonu i te pāmahana mā te whakamahi i ngā taumata hiko me ngā taputapu ine matatau. Ahakoa he rerekētanga 3μm ka puta i waenga i ngā inenga i tangohia i roto i ngā āhuatanga paerewa me ngā āhuatanga pāmahana-whakahaeretia - e whakaatu ana i te tūranga nui o te pumau taiao.
