Ka whānui ake rānei te turanga o te mīhini karāhe nā te wera i te wā e matawaihia ana te paparanga?

I roto i te hononga matua o te hanga maramara - te matawai wafer, ko te tika o ngā taputapu te mea e whakatau ana i te kounga o te maramara. Hei wāhanga nui o ngā taputapu, kua aro nui te hunga ki te raruraru whakawhānui wera o te turanga mīhini karāhe.

Ko te tauwehenga whānui wera o te karāneti kei waenganui i te 4 me te 8×10⁻⁶/℃, he iti iho i tērā o ngā konganuku me te māpere. Ko te tikanga o tēnei, ina rerekē te pāmahana, he iti noa te rerekētanga o tōna rahi. Heoi, me mōhio ko te iti o te whānui wera ehara i te mea kāore he whānui wera. I raro i ngā piki me ngā heke o te pāmahana, ahakoa te iti rawa o te whānui ka pā ki te tika o te matawai wafer.

I roto i te tukanga matawai wafer, he maha ngā take mō te puta o te whakawhānui wera. Ko ngā rerekētanga pāmahana i roto i te awheawhe, te wera i puta mai i te mahi a ngā wāhanga taputapu, me te pāmahana teitei ohorere i puta mai i te tukatuka laser ka meinga te turanga granite kia "whanui me te whakawhāiti nā ngā huringa pāmahana". Kia pāngia te turanga e te whakawhānui wera, ka rerekē pea te tika o te ara ārahi me te papatahi o te papa, ka hua ake he ara nekehanga hē o te tēpu wafer. Ka nekehia hoki ngā wāhanga whatu tautoko, ka "peke" te hihi matawai. Mā te mahi tonu mō te wā roa ka kohikohi hapa hoki, ka kino haere te tika.

Kaua e manukanuka. Kua whai otinga kē te tangata. Mō ngā rauemi, ka tīpakohia ngā uaua karāhe he iti ake te tauwehenga o te whakawhānui wera, ā, ka tukuna ki te maimoatanga tawhito. Mō te whakahaere pāmahana, ka whakahaeretia tika te pāmahana o te awheawhe i te 23±0.5℃, i raro iho rānei, ā, ka hangaia hoki he taputapu whakamarara wera hohe mō te turanga. Mō te hoahoa hanganga, ka whakamahia ngā hanganga ōrite me ngā tautoko ngāwari, ā, ka whakahaerehia te aroturuki wā-tūturu mā roto i ngā pūoko pāmahana. Ka whakatikatikahia ngā hapa i puta mai i te whakarerekētanga wera e ngā rauropi.

Mā roto i ēnei tikanga, ka mau tonu te pānga whakawhanui wera o te turanga karāhe ki roto i te awhe tino iti, ka taea ai te tika o te matawai wafer ki te taumata nanometer. Nō reira, mena ka whakahaeretia tika, ka noho tonu te turanga karāhe hei whiringa pono mō ngā taputapu matawai wafer.
