VS Teitei-Teitei Whakawhiti Ngaohiko
Whānui-aunoa whānuitanga ine
He hapa koki-wāhanga kua tautuhia mārama whakatakotoranga
Ko ngā ine hiko tuku iho ka tohua noa te hapa ōwehenga, ā, kāore e whakaratohia he whakatauranga koki-ā-wāhanga; nō reira, he pai anake mō te ine hiko takitahi. Heoi, ina whakamahia te ine hiko mō te ine mana, ka noho te hapa koki-ā-wāhanga hei mea nui e pā ana ki te tika. He mārama te whakatakotoranga koki-ā-wāhanga o ngā ine hiko raupapa VS, me te nekehanga ā-wāhanga noa iho i te 1 meneti-ā-whatu, ā, koinei te whiringa pai mō ngā tono ine mana.
Kei te ripanga i raro nei te rārangi o te hapa ine-mana i puta mai i te hapa koki-wāhanga 10′ (≈0.0029 rad, he ōrite ki te rohe hapa o te whakawhiti hikohiko akomanga 0.2) i te mea he rerekē te koki-wāhanga mai i te 0° ki te 90°:
Tau Raupapa | Koki wāhanga (°) | cos Φ | parauri Φ | Hapa mana i puta mai i te pekanga o te koki-wāhanga (%) |
1 | 30 | 0.866 | 0.5774 | 0.17 |
2 | 60 | 0.5 | 1.7321 | 0.5 |
3 | 78.5 | 0.1994 | 4.9152 | 1.4 |
4 | 87.1 | 0.0506 | 19.74 | 5.7 |
5 | 88.9 | 0.0192 | 52.081 | 15 |
E ai ki te ripanga, he pānga nui tō te hapa koki-wāhanga ki ngā inenga mana, ā, ka tino kitea i raro i ngā āhuatanga tauwehenga mana iti. Ka tukuna e te transducer ngaohiko tino tika a te VS he nekehanga wāhanga noa o te 2 meneti-āwhata, he whakatakotoranga tino pai e tiaki pai ana i te tika o te inenga mana.
