7. Pehea ka hopena o ka pāpaho porous i ke ʻano o ka lepo?

ʻO ka lepo, kahi ʻano porous kūlohelohe, e hoʻohuli i ka neʻe ʻana o ka wai a me ka loaʻa ʻana o nā meaʻai no nā mea kanu. ʻO ka hoʻomaopopo ʻana i ka porosity a me ka permeability o ka lepo hiki ke kōkua i ka wānana ʻana i ka hoʻokahe wai, ka lawe ʻana o nā meaʻai, a me ke komo ʻana o ke aʻa, e hoʻomaopopo ana i nā hana mahiʻai a me ka hoʻokele kaiapuni.

8. Hiki i nā mea hana porous ke hoʻokele i ka wela?

ʻAe, hiki i nā pāpaho porous ke hoʻokele i ka wela, ʻoiai ʻaʻole maʻamau ka maikaʻi ma mua o nā mea ʻaʻole porous. He paʻakikī ke kaʻina hana hoʻoili wela i loko o nā pāpaho porous, e pili ana i ka hoʻoili ʻana ma o ka matrix paʻa a me ka wai i loko o nā pores, a me ka hoʻoili wela convective inā e kahe ana ka wai.

9. Pehea e pili ai nā mea porous i ka acoustics?

He kuleana koʻikoʻi ko nā mea porous i ka omo ʻana o ke kani a me ka kaohi ʻana i ka walaʻau. Hiki i ke ʻano paʻakikī o nā pores ke hoʻopaʻa i nā nalu kani, e hoʻololi ana i ko lākou ikehu i wela a hoʻemi i ka nui o ke kani i hoʻihoʻi ʻia. ʻO kēia ka mea e maikaʻi ai nā mea porous no nā noi e like me ka insulation acoustic a me nā panela hoʻemi walaʻau.

10. Pehea e hoʻohālike ʻia ai nā ʻano o nā pāpaho porous?

ʻO ke kumu hoʻohālike i nā waiwai o nā pāpaho porous e pili ana i nā ʻano hana makemakika a me ka helu ʻana. Hiki i kēia mau kumu hoʻohālike ke ʻano mai nā simulations pore-scale, e hopu ana i ke ʻano kikoʻī o ka pūnaewele pore, a hiki i nā kumu hoʻohālike continuum e wehewehe ana i ke ʻano awelika ma luna o kahi nui.

11. He aha kekahi mau pilikia i ka hana ʻana me nā pāpaho porous?

ʻO nā pilikia me nā pāpaho porous e pili pinepine ana i ke ʻano a me ka wānana ʻana i kā lākou ʻano ma lalo o nā kūlana like ʻole. No ka laʻana, ʻo ka hoʻoholo pololei ʻana i ka hoʻolaha ʻana o ka nui o ka pore a i ʻole ka hoʻomaopopo ʻana pehea e pili ai nā loli kūkulu i ke kahe o ka wai hiki ke paʻakikī. Eia kekahi, i ka wā e hana ai me nā pāpaho porous kūlohelohe e like me nā pōhaku a i ʻole ka lepo, hoʻohui ko lākou ʻano like ʻole i kahi papa paʻakikī hou aʻe.

12. He aha kekahi mau kuhikuhi e hiki mai ana i ka noiʻi media porous?

He ākea a he interdisciplinary nā kuhikuhi e hiki mai ana i ka noiʻi media porous. Pili lākou i ka hoʻomohala ʻana i nā mea hou me ka porosity i hana kūikawā ʻia no nā noi kikoʻī, e hoʻoikaika ana i ko mākou ʻike i nā hanana halihali i nā ʻōnaehana porous, a me ka hoʻomaikaʻi ʻana i kā mākou mau hiki ke hoʻohālike. Ke loaʻa nei hoʻi nā wahi noiʻi e like me nā mea porous nanoscale a me nā ʻano porous i hoʻoulu ʻia e ka bio, e wehe ana i nā palena hou no ka ʻike a me ka hana hou.

I loko o ke ao e loli mau nei o nā pāpaho porous, ʻo ia kekahi o nā nīnau i nīnau pinepine ʻia. Eia naʻe, ʻaʻole i pau ka ʻimi ʻana i ka ʻike ma aneʻi. Ke hoʻomau nei nā kānaka ʻepekema a me nā ʻenekinia i ka ʻeli ʻana i loko o kēia kahua hoihoi, ke hoʻohiki nei ka wā e hiki mai ana i ka nui o nā ʻike hou, nā ʻenehana, a me nā noi e ʻimi ai.

Makemake ʻoe e ʻimi hou aku i ke ao o nā pāpaho porous?

Inā ʻoe e ʻimi nei i nā mea holomua no kāu papahana, ke kūkākūkā ʻana no kāu noiʻi, a i ʻole

makemake nui e kūkākūkā i ka hiki o nā pāpaho porous, eia mākou e kōkua. ʻO HENGKO, me ko mākou ʻike loea waiwai

a me ke kūpaʻa i ka hana hou i nā pāpaho porous, hoʻokipa iā ʻoe e hoʻokaʻaʻike aku.

Mai kānalua e kuhikuhi i kāu mau nīnau, manaʻo, a me nā manaʻo iāka@hengko.com.

E luʻu pū kākou i loko o ke ao hoihoi o nā pāpaho porous, a e ʻike pehea e hiki ai iā kākou

e hoʻokele i ka holomua a hana i nā hoʻonā no kahi wā e hiki mai ana. E hoʻokaʻaʻike mai i kēia lā!
