Mena kua pānui koe i te pepa taipitopito a te kaiwhakarato, ā, kua kite koe i tētahi rārangi pēnei i te "kua whakatikatikaina, ka taea te whai i ngā paerewa ā-motu," he māmā noa iho te wareware noa iho. Kaua e pērā. Ko te whai i ngā taipitopito tētahi o ngā mea ruarua kei runga i te pepa taipitopito ka taea te manatoko, ā, ko tētahi hoki o ngā mea e tino whakanuia ana.
Ko te mekameka, he whakamārama māmā noa iho
Ko te whai i te tikanga o te whai i te tika o tētahi taputapu ine, mā roto i tētahi mekameka whakataurite kore-whatu, ki tētahi paerewa ā-motu, ā-ao rānei kua whakamanahia. I roto i te mahi, he rite tēnei ki tētahi piramiti: he whare wānanga ine ine ā-motu — NIST i te US, PTB i Tiamana, NIM i Haina, NPL i te UK — e pupuri ana i ngā paerewa tohutoro tuatahi. Ka whakatauritea e ngā taiwhanga whakatikatika ā-rohe kua whakamanahia ā rātou taputapu tohutoro ki aua paerewa tuatahi i runga i tētahi wā kua tautuhia. Kātahi ka whakatikatikaina ngā taputapu tirotiro a te wheketere — ngā tohu waea, ngā ine whakawhiti laser, ngā taumata hiko — ki ngā tohutoro a te taiwhanga ā-rohe, me tētahi tiwhikete e whakaatu ana i te whakataurite, te rerekētanga ine, me te rā.
Momotuhia tetahi hononga o taua mekameka, ā, ka mutu te tikanga o te kupu "kua whakatikatikaina". Ko te taputapu i whakatikatikaina i te kotahi tau, e rima tau ki muri, ki ngā taputapu kāore i taea te whai i tētahi whare wānanga ā-motu, kāore he rerekētanga o te tikanga i tētahi taputapu kāore i whakatikatikaina - he tapanga noa iho kei a ia e whakaatu ana i tōna āhua rerekē.
He aha te hiranga ake o tēnei mō ngā papa kohatu me ngā papa karāhe
Ko ngā pereti mata karāhe me ngā papa ine tika he tauira pai o te korenga o te whai i te whai i roto i te mahi. Ko te papatahi o ēnei hua ka tohua i runga i te paerewa ā-motu — ko te DIN 876 me te DIN 875 o Tiamana, ko te GGG-P-463C o Amerika, ko te JIS B 7513 o Hapani, ko ngā paerewa ā-motu o Haina o te GB, ko te BS 817 o Peretānia, ko ngā anga rite rānei i Parani me Rūhia. Ka tautuhia e ia paerewa te rerekētanga papatahi e whakaaetia ana puta noa i ngā rahi me ngā taumata pereti rerekē (ko te nuinga ko te Tau 00, Tau 0, Tau 1, Tau 2). Kāore he tikanga o te pereti kua tohua ko "Tau 0" me te kore he tuhinga mō te paerewa i inehia ai, ko tēhea taputapu i inehia ai, me te mea ka taea te whai i te whakatikatika o taua taputapu.
Koinei anō te wāhi e nui ai te rerekētanga i waenga i te ine i te interferometer me te tirotiro tika ā-ringa. Ka taea e te interferometer laser te whakatau i ngā rerekētanga papatahi i te taumata nanometer, ā, ka whakatauritea ki te paerewa roangaru whatu, he mea ka taea te whai tika atu i te ine. He tere ake, he iti ake te utu o te whakataurite i te taha tika kua tirohia ā-ringa, engari he whānui ake te whānuitanga o te koretake, ā, he mārama tonu ngā taiwhanga rongonui mō te tikanga i whakamahia mō tētahi tiwhikete kua hoatu.
He rārangi arowhai poto mō ngā kaihoko
Mō te tangata e tohu anataputapu tino tika— ngā papa granite, ngā taputapu CMM, ngā moenga taputapu mīhini — he pai kia pātaihia ētahi pātai ki tētahi kaiwhakarato i mua i te tango i tētahi kereme "kua whakatikatikaina" i te uara mata:
- Ko tēhea paerewa ā-motu, ā-ao rānei i whakamahia ai te ine, ā, e whakahuatia māramatia ana i roto i te tiwhikete?
- Nā tēhea taiwhanga i tuku te tiwhikete whakatikatika, ā, kua whakamanahia taua taiwhanga e tētahi whare wānanga ine ine whenua rongonui ā-motu?
- He aha te taputapu i whakamahia mō te ine, ā, he rā whakatikatika me te pūkete whai i taua taputapu anō hoki?
- Kei te tukuna te tiwhikete mō te wāhanga tau-rangatū motuhake, he tuhinga whānui rānei mō te raina hua?
Ehara tēnei i te kōrero tauhou — ka tukuna noa mai e ngā kaiwhakarato rongonui, me te kore e pātaihia anō. Ko ngā wā e uaua ai te whiwhi whakautu tika, koinā ngā wā e tika ana kia tūpato.
