Ngā momo peera porowhita me ō rātou āhuatanga hanganga

1.Te whakarōpūtanga i runga i te ahunga o te kawenga

Ka taea te wehewehe i ngā peera porowhita ki ēnei wāhanga e whai ake nei, i runga i te ahunga o tā rātou kawenga, i te koki whakapā ingoa rānei:

a) Ngā peera pūtoro：Ko te nuinga o te kawenga he mea kawe i te kawenga radial, ā, ko te koki whakapā ingoa kei waenga i te 0°≤τ≤30°, e wehea ana kia rua: Whāriki porowhita whakapā radial: koki whakapā ingoa τ=0°, e tika ana mō te kawe i te kawenga radial me te kawenga tuaka iti. Whāriki porowhita whakapā koki: koki whakapā ingoa 0°<τ≤30°, e tika ana mō te kawenga whakakotahi me ngā kawenga radial me te tuaka i te wā kotahi.

b) Ngā peera pana：Ko te kawenga tuaka te nuinga, ā, ko te koki whakapā ingoa kei waenga i te 30°<τ≤90°, e wehea ana kia rua: Ko te whāriki porowhita pana whakapā tuaka: koki whakapā ingoa τ=90°, e tika ana mō te kawenga tuaka i te taha kotahi. Ko ngā whāriki porowhita pana whakapā koki: koki whakapā ingoa 30°<τ<90°, e tika ana mō te kawe kawenga tuaka, engari ka taea hoki te kawe kawenga whakakotahi.

Ngā peera pito tokotoko nohoanga me te waha raka: he kōhao kei roto o te kakau pito tokotoko, ā, he taputapu raka anō hoki.

4. Whakarōpūtia e te hiahiatanga o te whakahinuhinu anō me te tiaki

Ka taea te wehewehe i ngā peera porowhita kia rua ngā momo, i runga i te hiahia kia pania anō, kia tiakina hoki i te wā e mahi ana:

Ngā peera porowhita kua whakahinuhinuhia hei tiaki

Ngā peera porowhita kore tiaki, whakahinuhinu-ake

5.Te whakarōpūtanga e ai ki te rauemi takirua waku o te mata reti

E ai ki te huinga o ngā rauemi takirua waku i runga i te mata reti, ka taea te wehewehe i ngā peera porowhita ki:

Ngā peera porowhita maitai/maitai

Ngā peera porowhita maitai/parahi

Ngā peera porowhita hiato maitai/PTFE

Ngā peera porowhita papanga maitai/PTFE
