Te hononga mutunga kore i waenga i te kōrundum mā me te hangarau o muri mai
E mōhio ana te katoa o te ao hangarau he moni pakari ngā rauemi hou. Nā wai rā i whakaarokōrunuma mā, e āhua rite ana ki te huka mā, ka noho hei "kaiwhakatairanga ngaro" mō te hurihanga hangarau ā muri ake nei. Mai i ngā maramara waea pūkoro ki ngā wāhanga o te waka rererangi o Mars, mai i ngā rorohiko matū ki ngā taputapu hanumi karihi e whakahaeretia ana, ka kitea i ngā wāhi katoa. I tēnei rā, me tango e tātou tēnei paparanga o te koti hangarau, ka kite me pēhea te mahi puku a tēnei tohunga ahumahi i ngā mea nunui.
1. Te "ira hangarau" whai pūmanawa
Ko ngā āhuatanga pakari o te kōrundum mā he mea hanga noa iho mō ngā hangarau o muri mai. Me te pakeke Mohs o te 9.0, he iti noa iho te kino atu i te taimana. Kua whakahaerehia e tētahi wheketere mīhini whakaahua-ira i Shanghai tētahi whakamātautau whakatairite. Ka taea e te taratara o te mata o te ara arataki kua orohia ki te kōrundum mā te eke ki te Ra0.008μm. I pupuri te tohunga hangarau a Xiao Li i te mea mahi, ā, ka papaki i ōna ngutu: "Me tēnei tino tika, ka whati te wheua o te waeroa mēnā ka tū ki runga!"
He tino whakaharahara te pumau o te wera. E whakaatu ana ngā raraunga mai i tētahi taiwhanga hanumi karihi i Qingdao, i taea e ngā uku mā te kōrundum te tu atu i te pāmahana teitei o te 2000℃ mō ngā hāora 100, ā, he iti iho i te 0.01% te panonitanga o te rahi. I papaki te kairangahau a Lao Wang i te rūma korehau, ā, i mea ia: "Ka taea e tēnei rauemi te tū ki runga i te mata o te rā mō ngā rā e rua!"
2. "Ngā Toa Huna" i te Papa Ārahi-Haumaru
I roto i te papa pakanga nano-tauine o te hanga maramara, kua roa te korundum mā e noho ana hei "mōneka horoi". I whakamahia e tētahi wheketere wafer i Taizhou te paura moroiti korundum mā 0.1μm hei tapahi i ngā wafer silicon, ā, i whakaitihia te tere hinga o te taha ki te 0.2‰. I titiro a Master Lao Chen ki te karuārai ka kata: "Inaianei he pai ake te tapahi i ngā wafer i te tapahi tofu, ā, ko te tere hua ka eke tika ki te 99.98%!"
He pono rawa atu te whakakanapa o te karāhe o te mīhini whakakoi. He mea whakamiharo ngā raraunga mai i tētahi taiwhanga i Beijing: ka rongoatia te karāhe ki te wai whakakanapa nano corundum mā, ā, ko te papatahi o te mata e tae atu ana ki te λ/50 te roanga ngaru. I tohu te Kaiwhakahaere Hangarau a Lao Liu, ā, i mea: "He rite tēnei tika ki te tāuta i tētahi whakaata papatahi ki te Moana-nui-a-Kiwa!"
3. "Kīngi Kōpeketanga" i roto i te Ahumahi Rererangi
Ko te kōrunuma mā te mana whakatau whakamutunga mō te tukatuka i ngā wāhanga o te waka rererangi o Mars. Kei tētahi wheketere taputapu rererangi i Xi'an te whakamahi i ngā wira huri kōrunuma mā hei huri i ngā whāriki koranu titanium, ā, ka whakahaeretia te ahotea toenga o te mata ki roto i te ±5MPa. I mea te Inihinia Matua a Lao Zhang me te hikareti i roto i tōna waha: "Me tēnei taumata, me tuku e Musk he hikareti hei tono tohutohu!"
Kua eke ngā mata o ngā mīhini rererangi ki ngā taumata hou. He mea whakamiharo ngā raraunga o tētahi kamupene mīhini rererangi i Chengdu: he mata hiato uku korundum mā, ā, he ātete pāmahana tae atu ki te 1600℃. I titiro te taraiwa whakamātautau a Lao Li ki te papatohu, ā, ka rere te wai i te waha: "Me tēnei mahi, me karanga ngā mīhini rererangi ki a Papa!"
4. "Te Whakamana Manawanui" i roto i te Ara Pūngao Hou
He tino pai te kōrunuma mā ki te tapahi i ngā wahi pou pākahiko hiko. I inehia e tētahi wheketere pākahiko i Ningde: mā te whakamahi i te waea onepu kōrunuma mā hei tapahi i ngā paninga graphene, ka whakahaeretia te teitei o te pūwero ki raro iho i te 0.5μm. I papaki te kaiwhakahaere o te awheawhe, a Lao Zhou, i te pūtau pākahiko, ā, ka mea harikoa: "He pai ake te kaha o tēnei pākahiko i tā Tesla!"
5. "Arokite Hangarau Pango" o te Papa Pakanga o te Ao
He pai te kōrundum mā ki te whakamatao i ngā rorohiko kuantum. Kua whakawhanakehia e tētahi taiwhanga i Hefei tētahi kiriata kawe wera kōrundum mā te tauine nano me te kawe wera o te 400W/m·K. I whakamanamana te kairangahau a Lao Ma: "Inaianei he tere ake te marara o te wera o ngā moka kuantum i te paninga o te papa kirika!"
Ko te rauemi pakitara tuatahi o te hanumi karihi he kaha mārō ake. Ko te uku hiato korundum mā o tētahi whare rangahau i Mianyang he paepae kino i te hihi niutron e 6 ngā wā teitei ake i ērā o ngā rauemi tuku iho. I tohu te Inihinia Matua a Lao Zhao ki te tauhohenga, ā, i mea ia: "Ka tino pumau tēnei rauemi tae noa ki te wā e hangaia ai te tauhohenga arumoni!"
