Kurupae-H Waro maitai Q355/Q355B kua whakaritea mō te hangahanga, rahinga rarawe, utu whakataetae, tapahi piko tukatuka e wātea ana.
Kurupae H Hurihia WeraKo te wāhanga whakawhiti he mea hanga ki te tukutuku (te wāhanga poutū o waenganui) me ngā papa (ngā wāhanga whakapae i ia taha). He rite ngā mata o roto me o waho o ngā papa, ā, he āhua pewa te whakawhiti ki te tukutuku. Ko ēnei painga o tēnei hoahoa:
Kaha te kaha o te pikoMā te modulus wāhanga teitei ka nui ake te kaha kawe kawenga o ngā kurupae-I tuku iho me ngā hongere i te taumaha kotahi.
Te pumau o te hangangaKo te whānui ōrite o te flange e whakarato ana i te pakari taha tino pai, e pai ai mō te tautoko i ngā kawenga ahunga-rua.
Te whai huatanga o ngā rauemiKa whakaitihia te raruraru kukū ahotea e pā ana ki ngā wāhanga maitai tuku iho, ka penapenahia te 10% ki te 30% o te maitai.

Ngā Āhuatanga
H-kurupae maitaiHe kōtaha ōhanga te āhua whakawhiti-wāhanga e rite ana ki te reta Latina matua h, e mōhiotia ana hoki ko ngā kurupae maitai whānui, ngā kurupae-I whānui, ngā kurupae-I whānui whakarara rānei. Ko te wāhanga o te maitai āhua-H he tikanga kei roto i ngā wāhanga e rua: te tukutuku me te flange, e kiia ana hoki ko te hope me te taha. He iti ake te matotoru o te tukutuku o te maitai āhua-H i te matotoru o ngā kurupae-I noa me te teitei tukutuku ōrite, ā, he nui ake te whānui o te flange i te matotoru o ngā kurupae-I noa me te teitei tukutuku ōrite, nō reira e kiia ana hoki ko ngā kurupae-I whānui.
