Te Whakataki i te puranga rino Larsen

He aha te meaPuranga rino Larsen?
I te tau 1902, i hangaia tuatahitia e tētahi miihini Tiamana ko Larsen te ingoa, he momo puranga rino me te wāhanga whakawhiti āhua-U me ngā raka i ngā pito e rua, ā, i whakamahia angitu i roto i te hangarau, ā, i huaina ko "Puranga Rau Larsen" i muri i tōna ingoa. I ēnei rā, kua mōhiotia whānuitia ngā puranga rino Larsen puta noa i te ao, ā, kua whakamahia whānuitia hoki hei tautoko i te poka turanga, hei hanga i ngā tāwharau wai, hei tiaki waipuke me ētahi atu kaupapa.

He paerewa whānui o te ao te puranga rino Larsen, ka taea te whakaranu i te momo puranga rino Lassen kotahi i hangaia i ngā whenua rerekē ki roto i te kaupapa kotahi. Kua whakamāramahia e te paerewa hua o te puranga rino Larsen ngā whakaritenga me ngā whakaritenga mō te rahi whakawhiti-wāhanga, te momo raka, te hanganga matū, ngā āhuatanga miihini me ngā paerewa tirotiro o te rauemi, ā, me tino tirotirohia ngā hua i te wheketere. Nō reira, he pai te whakapumautanga kounga me ngā āhuatanga miihini o te puranga rino Larsen, ā, ka taea te whakamahi i ngā wā katoa hei rauemi hurihuri, he painga nui ki te whakarite i te kounga hanga me te whakaiti i te utu kaupapa.

 

Ngā momo puranga rino Larsen

E ai ki te whānui, te teitei me te matotoru o te wāhanga, ka taea te wehewehe i ngā puranga pepa maitai Larsen ki ngā tauira rerekē, ā, e toru ngā āhuatanga o te whānui whai hua o te puranga kotahi o ngā puranga pepa maitai e whakamahia whānuitia ana, arā, 400mm, 500mm me te 600mm.
Ka taea te whakarite i te roa o te Puranga Rau Rino Kukume me te whakaputa kia rite ki ngā hiahia o te kaupapa, ka taea rānei te tapahi kia poto, te whakarewa rānei kia roa ake i muri i te hoko. Mēnā kāore e taea te kawe i ngā puranga rau rino roa ki te papa hanga nā te iti o ngā waka me ngā rori, ka taea te kawe i ngā puranga o taua momo ki te papa hanga, kātahi ka whakarewahia, ka whakaroahia.
Rauemi puranga rino Larsen
E ai ki te kaha tuku o te rauemi, ko ngā taumata rauemi o ngā puranga pepa maitai Larsen e rite ana ki te paerewa ā-motu ko Q295P, Q355P, Q390P, Q420P, Q460P, me ētahi atu, ā, ko ngā mea e rite ana ki te paerewa Hapanihi koSY295, SY390, me ētahi atu. Haunga ngā momo matū, ka taea hoki te whakarewa me te whakaroa i ngā momo rauemi rerekē. Haunga ngā momo matū rerekē, he rerekē anō hoki ngā tawhā hangarau.
