Me pēhea te ine i te taratara o te mata?
Ka taea e koe te tatau i te taratara o te mata mā te ine i te toharite o ngā tihi me ngā awaawa o te mata puta noa i taua mata. E kitea ana te inenga ko 'Ra,' ko tōna tikanga ko 'Te Toharite Taratara.' Ahakoa he tawhā ine tino whai hua a Ra. Ka āwhina hoki ki te whakatau i te tutuki o tētahi hua, wāhanga rānei ki ngā paerewa ahumahi.
Ka taea tēnei mā te whakatairite ki ngā tūtohi whakaoti mata.
He aha ngā mea e rerekē ai a Ra me Rz i roto i te tūtohi taratara o te mata?
Ko Ra te ine i te roa toharite i waenganui i ngā tihi me ngā awaawa. Ka ine anō hoki i te rerekētanga mai i te rārangi toharite i runga i te mata i roto i te roa tauira.
I tētahi atu taha, ka āwhina a Rz ki te ine i te tawhiti poutū i waenga i te tihi teitei me te awaawa iti rawa. Ka mahia tēnei i roto i ngā roa tauira e rima, kātahi ka toharite i ngā tawhiti i inehia.
He aha ngā āhuatanga e pā ana ki te whakaotinga o te mata?
He maha ngā āhuatanga e pā ana ki te whakaotinga o te mata. Ko te mea nui rawa atu o ēnei āhuatanga ko te tukanga hanga. Ko ngā tukanga mīhini pēnei i te huri, te mira, me te huri ka whakawhirinaki ki ngā āhuatanga maha. Nō reira, ko ngā āhuatanga e pā ana ki te whakaotinga o te mata ko te

Te Tukanga o ngā Ngongo Tika
He rerekē te hangarau tukatuka me te hanga o ngā paipa maitai kore waikura tino pai te mahi teitei i ngā paipa tuimotu tuku iho. Ko ngā paipa tuimotu tuku iho ka hangaia mā te poka wera hurihuri-rua, ā, ko te tukanga hanga o ngā paipa ka whakamahia te tukanga tuhi. Ko ngā paipa maitai kore waikura tino pai ka whakamahia whānuitia i roto i ngā taputapu tino pai, i ngā taputapu hauora rānei. Ehara i te mea he teitei noa ngā utu, engari he maha hoki ngā wā ka whakamahia i roto i ngā taputapu me ngā taputapu matua. Nō reira, he tino teitei ngā whakaritenga mō te rauemi, te tino pai me te mutunga o te mata o ngā paipa maitai kore waikura tino pai.
Ko ngā ngongo hangai o ngā rauemi uaua ki te hanga, he mea hanga mā te werawera, ā, ko te hanga o ngā ngongo he mea tukatuka mā te hurihuri matao. Ko ēnei tukanga he tino tika, he nui te whakarerekētanga kirihou, ā, he pai ngā āhuatanga hanganga paipa, nō reira ka whakamahia.
Ko ngā paipa kowiri tira tino tika a te iwi whānui he kowiri tira 301, he kowiri tira 304, he kowiri tira 316, he kowiri tira 316L, he kowiri tira 310S. Ko te tikanga, he nui ake i ngā rauemi NI8 ka hangaia, arā, he rauemi kei runga ake i te 304, ā, kāore he ngongo kowiri tira tino tika me ngā rauemi iti e hangaia.
He tikanga te karanga i te 201 me te 202 he rino kowiri tira, nā te mea he aukume, ā, he kukume ki ngā aukume. Kāore hoki te 301 i te aukume, engari he aukume i muri i te mahi matao, ā, he kukume ki ngā aukume. Kāore ngā 304, 316 i te aukume, kāore he kukume ki ngā aukume, ā, kāore e piri ki ngā aukume. Ko te take matua mō te aukume, kāore rānei, ko te mea kei roto i te rauemi kowiri tira he chromium, he nickel me ētahi atu huānga i roto i ngā ōwehenga rerekē me ngā hanganga whakarewa. Mā te whakakotahi i ngā āhuatanga o runga ake nei, he tikanga whai hua hoki te whakamahi i ngā aukume hei aromatawai i te kounga o te kowiri tira, engari ehara tēnei tikanga i te pūtaiao, nā te mea i roto i te tukanga whakaputa o te kowiri tira, kei reira te kukume matao, te kukume wera, me te pai ake o te maimoatanga i muri i te tukatuka, nō reira he iti iho, he kore rānei te aukume. Ki te kore e pai, ka nui ake te aukume, e kore e taea te whakaata i te parakore o te kowiri tira. Ka taea hoki e ngā kaiwhakamahi te aromatawai mai i te takai me te āhua o ngā ngongo kowiri tira tika: te taratara, te matotoru ōrite, me te mea he paru kei runga i te mata.
He mea tino nui anō hoki ngā tukanga hurihuri me te tō i muri mai o te tukatuka paipa. Hei tauira, kāore i te tino pai te tango i ngā hinu whakahinuhinu me ngā waikura mata i te wā e whakaputa ana, ka pā kino tēnei ki te tika me te kounga o te mata o ngā paipa maitai kore waikura.
