E mōhio ana koe ki ngā āhuatanga katoa e whakaputa ana, e awe ana hoki i te ahotea ā-roto i roto i ngā hua i pokepokea ai i te werohanga?

1. te whakaputanga ahotea ā-roto
I roto i ngā hua i werohia, he rerekē te āhua o te ahotea ā-rohe i ia wāhi, ā, ko te nui o te whakarerekētanga o ngā hua ka whakatauhia e te tohatoha ahotea. Mena ka whakamataohia te hua. Mena he pikinga pāmahana, ka puta tēnei momo ahotea, nō reira ka kiia hoki tēnei momo ahotea ko te "ahotea whakairo".
Kia titiro tātou ki te whakaurunga omiihini tangohanga.

E rua ngā momo mōkihi ahotea ā-roto mō ngā hua i werohia: ko tētahi ko te ahotea whakairo, ko tētahi ko te ahotea pāmahana. Ina uru te rewa ki te pokepokea i te pāmahana iti iho, ka tere te whakamatao o te rewa e tata ana ki te pakitara o te kōhao, ka totoka, ā, ka "tio" ngā wāhanga mekameka ngota. Nā te ngoikore o te kawe wera o te paparanga pūmua totoka, ka hangaia he pikinga pāmahana nui i te ahunga o te matotoru o te hua. Ka tino puhoi te totoka o te ngākau o te hua, ā, ina kati te kuaha, kāore anō kia totoka te wae rewa i waenganui o te hua, ā, kāore e taea e te mīhini werohanga te whakakapi i te whakahekenga whakamatao.

Nō reira, ko te mimiti ā-roto o te hua kei te taha kē ki te mahi a te paparanga kiri mārō; kei roto te ngohengohe pumau o te uho, ko te paparanga mata ia kei roto i te pēhanga pumau.

Ina whakakīia te pokepokea e te rewa, ā, e rere ana, hei tāpiri atu ki te pānga whakaheke rōrahi i puta mai i te ahotea. Tērā anō ngā ahotea i puta mai i te pānga whānui o te putanga o te kaikawe me te kuaha; ko te pānga tuatahi ka puta he ahotea e pā ana ki te ahunga o te rere rewa, ko te pānga tuarua nā te pānga whānui o te putanga ka puta he ahotea i te ahunga poutū ki te rere.

2. Ngā āhuatanga tukatuka e pā ana ki te ahotea

(1) ki te pānga o te ahotea i roto i ngā āhuatanga whakamatao tere, ka arahi te aronga ki te hanganga o te ahotea ā-roto i roto i te pūmua. Nā te matotoru nui o te pūmua rewa, kāore e taea te whakangāwari wawe i te ahotea ā-roto, ka pā ki ngā āhuatanga ā-tinana me te pumau o te āhua o te hua.

Te awe o ngā tawhā rerekē ki ngā ahotea whakatakotoranga.

Te pāmahana rewa, te pāmahana rewa teitei, te matotoru iti, te ahotea kutikuti iti me te aronga iti; i tētahi atu ringa, mā te pāmahana rewa teitei ka tere ake te whakangā o te ahotea, ka whakatairanga i te kaha ki te whakapakari i te kore aronga.

Heoi, ki te kore e whakarerekētia te pēhanga o te mīhini whakarewa werohanga, ka piki ake te pēhanga o te kōhao pokepokea ai, ā, mā te pānga kutikuti kaha ka piki ake te ahotea whakatakotoranga.

Mā te whakaroa i te wā pupuri kia kati rā anō te pūwero ka nui ake te ahotea o te whakatakotoranga.

Mā te whakanui ake i te pehanga werohanga, mā te pupuri rānei i te pehanga ka nui ake te ahotea whakatakotoranga.

Mā te pāmahana teitei o te pokepokea ai ka āta whakamatao te hua, ā, ka mahi hei ārai i te nekehanga kore.

Whakanuia te matotoru o te hua hei whakaiti i te ahotea whakatakotoranga, nā te mea ka puhoi te whakamatao o ngā hua matotoru, ka puhoi te piki haere o te matotoru, ā, ka roa te tukanga whakangā ahotea, nō reira he iti te ahotea whakatakotoranga.

(2) Te pānga ki te ahotea pāmahana

E ai ki te kōrero i runga ake nei, nā te rerekētanga pāmahana i waenga i te rewa me te pakitara i te wā e whakakīia ana te pokepokea ai, me āwhina te paparanga o waho o te rewa e totoka ana i te tuatahi ki te aukati i te mimiti o te paparanga o roto o te rewa e totoka ana i muri mai, ka hua ake he ahotea pēhi (ahotea mimiti) i te paparanga o waho me te ahotea kume (ahotea aronga) i te paparanga o roto.

Ki te whakakīia te pokepokea ai, kātahi ka puritia i raro i te pēhanga mō te wā roa, ka tāpirihia te rewa pūmua ki te kōhao pokepokea ai, ka whakanui ake i te pēhanga kōhao, ka whakarerekē i ngā ahotea o roto nā te kore taurite o ngā pāmahana. Heoi, ki te poto te wā pupuri, ā, he iti te pēhanga kōhao, ka noho tonu te hua i roto i te āhua ahotea rite tonu ki te wā i whakamataohia ai.

Mena kāore i te rawaka te pēhanga o te kōhao pokepokea ai i te tīmatanga o te tukanga whakamatao, ka mimiti te paparanga o waho o te hua nā te totoka, ā, ka puta he pōuri; ki te kore e rawaka te pēhanga o te kōhao pokepokea ai i te wā o muri mai ina kua puta he paparanga mārō makariri o te hua, ka wehe te paparanga o roto o te hua nā te mimiti, ka puta rānei he kōhao; ki te mau tonu te pēhanga o te kōhao pokepokea ai i mua i te katinga o te kuaha, ka āwhina i te whakanui ake i te mātotoru o te hua me te whakakore i te ahotea pāmahana whakamatao, engari ka puta he kukū ahotea nui tata ki te kuaha.

Nō reira, te āhua nei ka roa ake te wā pupuri mēnā ka nui ake te pēhanga i roto i te pokepokea ai, ā, ka āwhina tēnei ki te whakaiti i te ahotea whakaheke e puta mai ana i te pāmahana, ā, ka whakapiki ake hoki i te ahotea pēhanga.

3. Te whanaungatanga i waenga i te ahotea ā-roto me te kounga o te hua

Ka pā kino te noho o te ahotea ā-roto i roto i te hua ki ngā āhuatanga miihini me te mahi a te hua; nā te koretake o te tohatoha o te ahotea ā-roto, ka pakaru te hua i te wā e whakamahia ana. Ina whakamahia i raro iho i te pāmahana whakawhiti karāhe, ka puta pinepine te whakarerekētanga āhua koretake, te piko rānei, ka taea hoki te "mā" me te kapua o te mata o te hua, ka heke hoki ngā āhuatanga whatu.

Mā te whakaheke i te pāmahana i te kēti me te whakanui ake i te wā whakamatao ka āwhina i te whakapai ake i te kore taurite o te ahotea i roto i te hua, ā, ka hanga kia ōrite ngā āhuatanga hangarau o te hua.

Mō ngā pūmua tioata me ngā pūmua kore-kiriata, he anisotropic te kaha kume. Mō ngā pūmua kore-kiriata, ka rerekē te kaha kume i runga i te wāhi o te kēti; ina rite te ahunga o te kēti ki te whakakī pokepokea ai, ka heke te kaha kume i te pikinga o te pāmahana rewa; ina poutū te kēti ki te ahunga whakakī pokepokea ai, ka piki te kaha kume i te pikinga o te pāmahana rewa.

Ko te pikinga ake o te pāmahana rewa ka hua ake te kore aronga me te hekenga o te kaha kume nā te hekenga o te aronga. Ka pā te aronga o te kuaha ki te aronga mā te awe i te ahunga o te rere, ā, nā te mea he anisotropic ake ngā polymer amorphous i ngā polymer crystalline, he nui ake te kaha kume i te ahunga poutū ki te rere mō te mea tuatahi i te mea tuarua. He nui ake te anisotropy ā-pūkaha o te werohanga pāmahana iti i te werohanga pāmahana teitei, hei tauira, ko te ōwehenga kaha i te ahunga poutū ki te ahunga rere he 1.7 i ngā pāmahana werohanga teitei, me te 2 i ngā pāmahana werohanga iti.

Te āhua nei ko te pikinga o te pāmahana rewa, ahakoa mō ngā pūhui tioata, mō ngā pūhui kore-kitea rānei, ka arahi ki te hekenga o te kaha kume, engari mā tētahi tikanga rerekē; ko te mea tuatahi i puta mai i te pānga whakaiti mā te whakatakotoranga.
