Te whakataki o te para parahi me te para maitai me te pānga o te onepū

Ko te para parahi te para i puta i muri i te whakarewa me te tango i te konganuku parahi, e mōhiotia ana ko te para rewa. Ka tukatukahia te para mā te kuru me te tātari kia rite ki ngā whakamahinga me ngā hiahia rerekē, ā, ko ngā whakatakotoranga e whakaatuhia ana e te maha o ngā mata, e te rahi rānei o ngā matūriki.

He pakeke rawa te para parahi, he rite tōna āhua ki te taimana, he iti te nui o ngā katote pūhaumāota, he iti noa te puehu i te wā e pupuhi ana i te onepu, kāore he parahanga taiao, ka whakapai ake i ngā āhuatanga mahi a ngā kaimahi pupuhi onepu, he pai ake te pānga tango waikura i ētahi atu onepu tango waikura, nā te mea ka taea te whakamahi anō.d, he tino nui hoki ngā painga ōhanga, 10 tau, kei te whakamahi ngā whare hanga, ngā wāhi hanga kaipuke me ngā kaupapa hanganga rino nui i te konganuku parahi hei tango i te waikura.

Ina hiahiatia he peita rehu tere, whai hua hoki, ko te para parahikoia te kōwhiringa tino pai.

Ko te tukanga tukatuka para maitai he mea hei wehewehengā huānga rerekē mai i te para. Kei roto ko te tukanga wehenga, te kuru, te tātari, te wehenga aukume, me te wehenga hau o te para i puta i te tukanga whakarewa maitai. Ka wehea, ka tukatukahia, ka whakamahia anōtia te rino, te silicon, te konumohe, te konupora, me ētahi atu huānga kei roto i te para hei whakaiti i te parahanga taiao me te whakatutuki i te whakamahinga whai hua o ngā rauemi.

Kei runga ake i te taumata Sa2.5 te mutunga o te mata o te mea mahi i muri i te maimoatanga para maitai, ā, kei runga ake i te 40 μm te taratara o te mata, he nui tēnei hei whakatutuki i ngā hiahia whānui mō te paninga ahumahi. I taua wā anō, e pā ana te mutunga o te mata me te taratara o te mea mahi ki te rahi o te matūriki o te para maitai, ā, ka piki ake i te pikinga o te rahi o te matūriki. He ātete kuru te para maitai, ā,ka taea te hangarua.

Te rerekētanga pānga：

1. Te tirotiro i te mutunga o te mata o ngā tauiraI te whakamahinga o ngā rauemi huri rerekē, i kitea he kanapa ake te mata o te mea mahi i maimoatia ki te para parahi i tērā o te para maitai.

2. Ko te taratara o te mea mahi i tukinotiaHe nui ake te para parahi i te para maitai, nā ēnei take e whai ake nei: he koi ake ngā taha me ngā koki o te para parahi, ā, he kaha ake te pānga tapahi i te para maitai, he māmā ake te whakapai ake i te taratara o te mea mahi.
