Te tinei auau teitei me te tinei auau waenga

I roto i te ao tukatuka whakarewa, ko te tinei he tukanga maimoatanga wera noa, he mea nui hoki, i hangaia hei whakapai ake i te pakeke, te ātete ki te kakahu me te kaha o ngā rauemi whakarewa. I roto i ēnei, ko te tinei auau teitei ngā tikanga tinei e rua e whakamahia whānuitia ana, he āhuatanga ahurei me te whānuitanga o ngā tono.

Ko te tinei auau teitei he tukanga e whakamahi ana i te iahiko auau teitei (100 kHz-500 kHz). Nā ōna āhuatanga auau teitei, he tino tere te tere o te whakamahana, ka taea te whakamahana i te mata whakarewa ki te pāmahana tinei i roto i te wā poto rawa. Mā tēnei whakamahana tere ka pāpaku te hohonu o te whakamahana, i waenga i te 0.5 me te 2.5 mm. Nā tēnei āhuatanga ka tino pai te tinei auau teitei mō ngā wāhanga iti me te angiangi e hiahia ana kia whakapakeketia te mata engari kāore e hiahia kia nui te mahi ā-roto, pērā i ngā taputapu iti, ngā pine me ngā taputapu.

Hei tauira, nā te iti o te rahi o ngā wāhanga tika o ngā taputapu hiko, me te hiahia kia pakeke rawa, kia ātete hoki ki te kakahu, ka taea e te tinei auau teitei te tukatuka tika i te mata me te kore e pā ki te mahi whānui o ngā wāhanga, me te whakapai ake i te roa o te ora ratonga me te pumau o te mahi.

Mō te tineitanga IF, ka whakamahia he iahiko IF o te 1-10 kHz mō te whakamahana. Ki te whakatauritea ki te tineitanga auau-tiketike, he puhoi ake te tere whakamahana, engari he nui te hohonutanga whakamahana, tata ki te 2-10 mm. Nā tēnei ka pai ake te tineitanga IF mō te whakahaere i ngā rahi nui me ngā wāhanga matotoru, pērā i ngā mea nunui. Poungā taputapu nunui, me ngā wāhanga mīhini e pikau ana i ngā kawenga nunui ake.

Tangohia te rakau taraiwa o te nui Ngā Utauta Mīhini Hei tauira, mā te tinei auau reo ka taea te whakarite i te pakari o roto o te rakau i te wa ano, ka taea e te mata te whiwhi i te pakeke me te ātete kakahu, kia pai ake ai te pono me te roa o te ratonga o te rakau taraiwa i raro i te ahuatanga o te mahi tere teitei me te kawenga taimaha.

Mai i te tirohanga utu taputapu, he iti te utu o ngā taputapu tinei auau-teitei, engari he whāiti te whānuitanga o te whakamahinga. He nui ake te utu o ngā taputapu tinei auau-waenga, engari ka taea te whakahaere i ngā momo me ngā rahi wāhanga nui ake.

Mō te whakamahinga pūngao, he iti noa te whakamahinga pūngao o te tinei auau teitei nā te poto o te wā whakamahana, ko te tinei auau waenga ia he nui te whakamahinga pūngao nā te hohonutanga o te whakamahana me te roa o te wā tukatuka.

Ahakoa he tinei auau teitei, he tinei auau waenga rānei, me whakaaroaro whānui, me whiriwhiri kia rite ki ngā whakaritenga motuhake, te āhua, te rahi me te taiao whakamahinga o ngā wāhanga. Mā te whiriwhiri i te tikanga tinei tika anake ka taea ai e tātou te whakamahi katoa i ngā painga mahi o ngā rauemi whakarewa, te whakapai ake i te kounga me te pono o ngā wāhanga, me te whakatutuki i ngā hiahia o ngā momo whakaputanga ahumahi.

I roto i te poto, ko te tinei auau teitei me te tinei auau waenga he tikanga nui i roto i te mara o te maimoatanga wera whakarewa, ā, he mahi nui tā rāua i roto i ngā horopaki tono rerekē, ā, he takoha nui tēnei ki te whakapai ake i te kounga me te mahi a ngā hua whakarewa.
