Me pēhea te whakakapi i te parahi hei hikohiko i te karāpeti? I tohaina eTe hikohiko karapiti kaha miihini teitei Haina.
I ngā tau 1960, i whānuitia te whakamahinga o te parahi hei rauemi hiko, ā, tata ki te 90% te tere whakamahinga, ā, tata ki te 10% noa iho te karāpiti. I te rautau 21, ka tīmata te tokomaha o ngā kaiwhakamahi ki te whiriwhiri i te karāpiti hei rauemi hiko. I Ūropi, neke atu i te 90% o ngā rauemi hiko he karāpiti. Ko te parahi, i mua ko te rauemi hiko matua, kua tata ngaro tōna painga ki te karāpiti. He aha te take o tēnei huringa nui? He pono, he maha ngā painga o te hiko karāpiti.
(1) te tere tukatuka tere ake: i te nuinga o te wā, ko te tere tukatuka ā-pūkaha oIrahiko karāpiti hei hokoe 2~5 ngā wā tere atu i te parahi; Heoi, e 2~3 ngā wā tere atu te edm i te parahi, ā, he iti ake te ngāwari o te rauemi ki te whakarerekē. Ko te pūwāhi whakangawari o te parahi he tata ki te 1000 nekehanga, ā, he ngāwari ki te whakarerekē i te wera. Ko te pāmahana whakangawari o te graphite he 3650 nekehanga; Ko te tauwehenga o te whakawhānui wera he 1/30 noa iho o te parahi.
(2) mama ake: ko te matotoru o te karāpeti he 1/5 noa iho o te matotoru o te parahi, ka taea te whakaiti i te taumaha o te taputapu mīhini (EDM) ina tukatukahia ngā irahiko nui mā te tukunga; He pai ake mō te tono pokepokea nui.
(3) he iti ake te whakamahinga tukunga; Nā te mea kei roto hoki i te hinu mura ngā ngota C, i te wā e tukatuka ana i te tukunga, ka pakaru ngā ngota C i roto i te hinu mura i te pāmahana teitei, ka hanga he kiriata tiaki i runga i te mata o te irahiko karāhe, hei utu mō te ngaronga o te irahiko karāhe.
(4) kāore he pūwero; I muri i te tukatuka i te hiko parahi, me kuti ā-ringa kia tangohia ngā pūwero, i te wā e tukatukahia ana te karāpeti e teTe wheketere hiko graphitekāore he pūwero, e penapena ana i te nui o ngā utu, ā, e māmā ake ai te whakahaere aunoa i te whakaputanga
(5) he māmā ake te huri me te whakakanapa i te karāpeti; Nā te mea he haurima noa iho te ātete tapahi o te karāpeti i te parahi, he māmā ake te huri me te whakakanapa mā te ringaringa
(6) te iti o te utu rauemi, me te pumau ake o te utu; Nā te pikinga o te utu parahi i ngā tau tata nei, he iti ake te utu o te karāhe isotropic i tō te parahi. I raro i te rahinga kotahi, ko te utu o ngā hua karāhe whānui o te waro toyo he 30% ~ 60% te iti iho i tō te parahi, ā, he pumau ake te utu, he iti noa te pikinga o te utu mō te wā poto.
Nā tēnei painga kore e taea te whakataurite, kua āta whakakapia te parahi e te karāpiti hei rauemi pai mō te hiko EDM.
