Ko te mata tika o te karāhe he "paerewa e kore e kitea" hei whakarite i te tika o ngā raina whakaputa taputapu miihini. Ko ngā whakaaro matua e pā tika ana ki te pumau o te raina whakaputa katoa me te reiti tohu hua, e whakaatuhia ana i roto i ngā ine e whai ake nei:
Te "kore e taea te whakakapi" o te tohutoro tika
Ko te tāutanga me te whakatinanatanga o ngā ara ārahi taputapu mīhini me ngā tēpu mahi i roto i te raina whakaputa me ahu mai i te tika (≤0.01mm/m) me te whakarara (≤0.02mm/m) o te taha tika o te karāhe. Ka taea e tōna rauemi māori-kiato teitei (3.1g/cm³) te pupuri i te tika mō te wā roa, me te tauwehenga whānui wera o te 1.5×10⁻⁶/℃ anake. Ahakoa te nui o te rerekētanga pāmahana i roto i te awheawhe, e kore e neke te tohutoro nā te "whānui me te whakaheke wera" - he "pūmautanga" tēnei e kore e taea e ngā rūri whakarewa te whakatutuki, ka karo tika i ngā hapa huihuinga taputapu i puta mai i ngā tohutoro hē.
2. Te "Kēmu Pakari" o te Ātete-wiri me te Ātete Mau
He uaua te taiao whakaputa, ā, he mea noa te tauhiuhi o ngā kongakonga wai whakamatao me ngā kongakonga rino. Nā te pakeke teitei o te karāhe (me te pakeke Mohs o te 6-7) ka ātete ki te rakuraku, ā, e kore e waikura, e pakaru rānei i ngā kongakonga rino pērā i te rūri rino maka. I taua wā anō, he kaha te mimiti wiri ā-taiao. I te wā e ine ana, ka taea e ia te whakaiti i te pokanoa wiri i puta mai i te mahi a te taputapu mīhini, ka pumau ake ngā pānui o te caliper vernier me te tohu mata, ā, ka karohia hoki ngā rerekētanga ine i puta mai i te kakahu o te taputapu.
"Lexile Adaptation" mō ngā horopaki
He rerekē ngā whakaritenga mō te roa me te tika o te rūri i ngā raina whakaputa rerekē:
Mō ngā raina whakaputa wāhanga iti, whiriwhiria he rūri 0-tohu me te diameter o te 500-1000mm, he mama, ā, e tutuki ana i ngā paerewa tika.
Ko ngā raina huihuinga taputapu mīhini taumaha e hiahia ana ki ngā rūri tika 2000-3000mm te rahi 00. Mā te hoahoa mata mahi-rua ka taea te whakatikatika i te whakarara o ngā reera arataki o runga me raro i te wā kotahi.
4. Te "Uara Huna" o te Whakahaere Utu
Ka roa ake te ora o tētahi rūri karāhe kounga teitei mō ngā tau neke atu i te 10, he iti ake te utu mō te wā roa atu i tētahi rūri whakarewa (me te huringa whakakapinga o te 3 ki te 5 tau). Ko te mea nui ake, ka taea te whakaiti i te wā whakatikatika taputapu mā te whakatikatika tika. I kōrero tētahi wheketere wāhanga waka, i muri i te whakamahinga o ngā rūri karāhe, i piki ake te whai huatanga o te whakawhiti tauira raina whakaputa me te whakatikatika mā te 40%, ā, i heke te tere para mai i te 3% ki te 0.5%. Koinei te kī ki te "penapena moni me te whakapai ake i te whai huatanga".
Mō ngā raina whakaputa, ehara i te mea he taputapu ine noa iho ngā rūri karāhe engari he "kaitiaki tika". Mā te whiriwhiri i te mea tika ka whakawhirinaki te kounga o te raina katoa. He taputapu ine karāhe nui ēnei mō ngā raina whakaputa tika ā-ahumahi.
