Kōwhiringa mīhini tohu taiaho
Ka taea te whakamahi i ngā taiaho hei tohu me te tukatuka i ngā hua maha, engari kāore he momo taiaho kotahi e tika ana mō ngā tono katoa. Ina pāngia e te mārama, ka "whakaatahia," ka "mimitia," ka "tuku" ngā mea katoa. Nō reira, ka rerekē te mahi a ngā mīhini tohu taiaho muka, CO₂, me te UV i runga i te tono me te rauemi.
Ka nui ake te "whakaata" me te "tuku", ka uaua ake te pikinga o te pāmahana o te mea, ka uaua ake te tukatuka. Ka nui ake te "mimiti", ka nui ake te pai o te tukatuka.
Te Whakaata + Te Ngongo + Te Tuku = 1
Ngā Kaupapa Taketake o te muka, te CO2, me te UV Laser
Ko te rerekētanga nui i waenga i ngā mīhini tohu muka, CO₂, me te UV laser kei roto i te roangaru o te mārama e whakaputaina ana e rātou. Ko ngā roangaru poto ake he nui ake te pūngao me te tere mimiti teitei ake i ngā roangaru roa ake. Nō reira, ka pā te roangaru o te laser ki tōna kaha ki te tohu i ētahi rauemi.
Kei raro nei ngā āhuatanga me ngā tauira tohu o ngā momo roangaru rerekē.
A: Awhe hihi-ā-ira B: Awhe kitea C: Awhe whero-pōkākā
He aha te muka taiaho?
Ko te roanga ngaru o te reera muka he 1090 nm, ā, he reera pūwhero (IR). Ka taea e ngā reera muka te tohu i te whānuitanga o ngā rauemi, ā, he tino pai mō te tohu i ngā mea whakarewa. Nā te kaha nui o ēnei mea, he pai mō te whakamahana me te whakairo. Heoi, kāore e taea te tohu i ngā mea mārama, nā te mea ka tika te haere o te mārama pūwhero mā roto i aua mea.

He aha te taiaho CO2?
He tekau ngā wā te roa o te roanga ngaru o ngā reihi CO2 i ngā pūnaha roanga ngaru paerewa. He tino pai ki te tohu i te pepa, te kapia, te rakau, te rapa, me ngā rauemi mārama pēnei i te karāhe me te PET. Heoi, kāore e taea te tohu i ngā konganuku ki te reihi CO2 nā te mea kāore te mārama reihi e mimitihia e te mea.
A: Awhe hihi-ā-ira B: Awhe kitea C: Awhe whero-pōkākā
He aha te taiaho UV?
Ka whakamahia e ngā taiaho UV he roangaru mimiti-tino (355 nm) hei tohu i ngā wāhanga. Mā tēnei tere mimiti-tino teitei ka taea e ngā taiaho UV te mahi "tohu makariri," arā, kāore he ahotea wera tāpiri e pā ana i te wā e tohu ana. Nō reira, he kōwhiringa pai ngā taiaho UV mō ngā tono e hiahia ana ki te rerekētanga teitei, ki te iti rānei o te kino o te hua.

Tātaritanga maha-ahu
I ngā wā maha, ka taea te whakamahi i ngā momo mīhini tohu taiaho maha i runga i te rauemi takai kotahi. Hei āwhina i ngā kaiwhakamahi ki te whiriwhiri i te hua tino tika, ka arotakehia e mātou ngā mīhini tohu taiaho i runga i ngā āhuatanga matua e rima: te whai huatanga o te utu, te kounga o te tohu, te whānuitanga o te tono, te kawe, me te kino o te wera.
Te whai huatanga o te utu:E pā ana ki te nui o te haumitanga e hiahiatia ana hei hoko i ngā taputapu me ōna utu tiaki. Ko te uara teitei ake e tohu ana he nui ake te haumitanga e hiahiatia ana.
Te Kounga Tohu:E whakaatu ana i te ātaahua me te ōrite o ngā rārangi tohu, tae atu ki te ngāwari o te pānui o te tohu. Ko te uara teitei ake e tohu ana i ngā hua tohu pai ake.
Ngā momo mahi: E whakaata ana i te maha o ngā momo rauemi ka taea e te mīhini tohu te whakahaere. Ko te tikanga o te uara teitei ake ka taea e te mīhini te tohu i te whānuitanga o ngā rauemi.
Te kawe: E whakaatu ana i te rahi ā-tinana o te hua, te uaua o te tāutanga, me ngā whakaritenga mō ngā āhuatanga taiao pēnei i te pāmahana me te wāhi. Ko te ngāwari ake o te kawe, ko te ngāwari ake, ko te ngāwari ake hoki o te tāutanga.
Te kino wera: E pā ana ki ngā panonitanga o ngā āhuatanga ā-tinana, ā-matū rānei o te rauemi. Nā te mea he tahu wera te tohu taiaho, ka iti ake te kino o te rauemi ki te iti o te hihi wera.
Otinga i Manakohia
Ka taea e ngā reera muka te tohu tere i te nuinga o ngā rauemi, ā, ka puta he rerekētanga kaha ki runga i ngā konganuku. Heoi, kāore e taea e rātou te tohu i ngā rauemi mārama, ā, i ētahi wā ka kino pea te mata e tohua ana. Ka eke ngā reera UV ki te rerekētanga teitei ki runga i ngā kapia, ā, ka tukuna he painga ahurei o te hanga tohu kore-kino. Ka tohu ngā reera CO₂ i ngā ūnga mā te tahunga wera, he mea pai mō te tohu i te rakau, te pepa, te uku, me ngā rauemi mārama.
