Paura Moroiti Kakariki Silicon Carbide: He Paerewa Hou mō ngā Rauemi Tino Pai, Tiaki Pūngao
I. He aha tonu tēnei? He aha i huaina ai ko "Hardcore"?
Tuatahi, kia mārama tātou he ahapaura moroiti karawiti silicon matomatohe. Whakaarohia he momo "taimana horihori." Ahakoa he iti ake te mārō o te taimana tūturu, he mea whakakoi tino pai rawa atu. Ka paraihia i roto i te oumu ātete pāmahana teitei i te neke atu i te 2,000 nekehanga Celsius ma te whakamahi i te onepu quartz, te petroleum coke, me ētahi atu rauemi mata, ka puta tōna tae kakariki motuhake.
Ko tōna āhua "pakari" e whakaatahia ana i roto i ngā āhuatanga e toru:
Te Pakari Teitei me te Mata Koi: Ko tōna pakari Mohs ka eke ki te 9.2, ko te tuarua anake ki te taimana. Ko te tikanga o tēnei, ina tapahia, ka huri, ka rite ki te niho koi iti, e ngāwari ana te "huri" i roto i ngā rauemi pakeke me te pakarukaru pērā i ngā papa silicon photovoltaic, te karāhe hapaira, me ngā tioata piezoelectric.
Te Pakari Nui, Pai ake te Pakaru Kaua e Piko: Kāore e ranea te pakari anake; me roa hoki te ora. He pakarukaru rawa ētahi rauemi, ā, ka pakarukaru hei paura angiangi ina pēhia, ā, ka kore e whai hua. He pakari te paura moroiti silicon carbide matomato, engari he tino pakari tonu. Ka mau tonu tōna āhua i raro i te pēhanga nui, ka kaha te whakamahi ki te mea mahi me te kore e pakaru.
Pūmau te matū, ā, he uaua ki te mahi: I te pāmahana rūma, kāore e tauhohe ki ngā waikawa, ki ngā kawa rānei, ā, he rauemi uaua ki te mahi. Ko te tikanga o tēnei, i te wā e tapahia ana, ka karohia ngā tauhohenga matū kāore e hiahiatia ki te rauemi e tukatukahia ana, kia mā ai te rauemi. He mea nui tēnei mō ngā ahumahi photovoltaic me te semiconductor, he mea nui te parakore.
II. Te whai huatanga nui me te penapena pūngao—ehara i te mea he pepeha noa iho
Te tīmatanga ki te kaupapa: He aha i huaina ai ko te "paerewa hou"? Me pēhea te whakaatu i ēnei mahi tino whai hua me te penapena pūngao? Me whakapoto tātou i ngā kōrero kino, ā, me whakaatu i ētahi āhuatanga whai hua.
Horopaki 1: Ngā "Kaitapahi Tika" o ngā Waferi Silicon Photovoltaic
E Lao Zhang, ko koe te mea tino mōhio ki tēnei.Rauemi siliconHe tino utu nui i ēnei rā. Mā te tapatapahi angiangi ka nui ake ngā papa angiangi, ka whakaitihia ngā utu. Heoi, he ngawari ake te pakaru o ngā papa angiangi, me te hiahia kia teitei ake ngā paerewa mō te hangarau tapahi me ngā mea whakakoi. Ko te paura iti karāhe silicon kakariki, me tōna āhua matūriki ōrite me ōna taha koi, ka puta he kaha tapahi pumau me te ōrite i te wā tapahi. Ko te hua:
Te tino pai o te tapahi: Ka taea te tapahi i ngā angiangi maha i roto i te wā kotahi, ka taea rānei te whakanui ake i te tere tapahi.
Kounga mata tino pai: He iti noa te pakaru o te mata o ngā anga silicon kua tapahia, ā, he iti te TTV (te rerekētanga matotoru katoa), ka tere te pikinga o te hua.
He iti te ngaronga rauemi: Mā te tapahi tika ka iti te ngaronga o te kerf, ka whakaitihia te moumou o te rauemi silicon utu nui. Mō ngā haumitanga e neke atu ana i te rau miriona yuan, he nui tēnei penapena.
Horopaki 2: Te "kaitākaro manawanui" o te tukatuka hapaira
He maha ngā uhi kāmera me te karāhe mataaratanga papai o tō waea pūkoro he mea hanga ki te hapaira. He mārō ake te hapaira i te karāhe, ā, he tino uaua ki te tukatuka. Mā te whakamahi i ngā mea whakakoi noa ka memenge i muri i te wā poto, ka tino whakaiti i te pai o te mahi. Heoi, nā te ātete pai ki te kakahu, ka mau tonu te mata tapahi koi mō te wā roa, ka roa ake te ora o te mahi. Ko te tikanga tēnei:
Ka whakaitihia te auau o ngā whakawhiti kōhatu, ka whakapotohia te wā whakamutu mahi, ā, ka whakapaitia te whai huatanga o te whakaputa.
Ka whakaitihia ngā utu tukatuka katoa. Ahakoa he nui ake te utu mō ia tana, mā te pikinga ake o te whai huatanga me te whakaiti i ngā taonga pau ka whakaitihia te utu katoa. Koinei te "penapena pūngao" pono.
Horopaki 3: Te Whanui ki tētahi Ao Whānui
Kei tua atu i tēnei ōna āheinga. Mā te tāpiri atu ki ngā rauemi ātete matatau ka roa ake te ora o ngā oumu me te whakapai ake i te whakamarumaru, ka penapena pūngao i roto i ngā oumu ahumahi e nui ana te pūngao. I roto i ngā rauemi hiato, hei whakakaha, ka ātete ake i te kakahu me te kaha ake o ngā wāhanga, ka roa ake ngā huringa tiaki taputapu—he momo penapena pūngao huna hoki. Ahakoa i roto i te umanga rererangi, he mea nui rawa atu mō te huri tika o ētahi wāhanga uku motuhake.
III. Te Huarahi kei mua: He Pai Ake, He ōrite Ake, He mātau Ake
Ae, ehara i te mea tino tika te paura iti o te silicon carbide matomato. Hei whakatutuki i tēnei "paerewa hou," me mahi kaha ā mātou kaihanga i roto i ētahi wāhanga:
Te whakapai tonu i te rahi o te matūriki: Kei te hiahia ngā ahumahi o raro kia nui ake te tika. Me whakaputa e tātou he paura moroiti me te tohatoha rahi matūriki kukū ake me te āhua matūriki ōrite ake (he pai ake te isomorphism). He rite tēnei ki tētahi rōpū hōia e hikoi tahi ana, e neke ana i te huarahi kotahi mō te whai huatanga o te whawhai. Me tino whakahaere te ihirangi o ngā matūriki nunui me ngā matūriki iti (e kiia nei ko te "coarse" me te "fine"); ki te kore, ka puta he karawarawa ki te mahi, ā, ka heke te pai o te mahi i te tapahi.
Te toi o te whakarerekētanga mata: Te whakarerekētanga mata ongā matūriki paura itiHe mahi hangarau tino nui tēnei. Hei tauira, mā te whakarei ake i te hototahitanga ki ngā wai tapahi me ngā here kapia ka taea te whakapai ake i te pai o te tapahi me te mahi a te hua. He rite ki te hinu i te hoari—ehara i te mea ka whakakoi noa i tōna mata engari ka whakanui ake hoki i tōna pakari.
Te Whakakakariki i te Tukanga Hanga: Ahakoa he rauemi penapena hiko, ka taea hoki e tana tukanga hanga te whai hua ake i te hiko me te pai ake ki te taiao? Hei tauira, ko te whakapaunga hiko i roto i ngā oumu whakarewa, te kohikohi puehu i te wā e kuru ana me te tātari, me te hangarua wai—ngā wāhanga katoa e hiahia ana kia whakapai ake tonu me te whakahou i roto i tā mātou umanga. Ka whai mātou ki te waihanga rauemi matomato puta noa i tō rātou huringa ora katoa.
Ki a tātou i roto i te umanga rauemi, kua tīmata noa te kōrero mō te paura iti karāhe silicon carbide matomato. Ko te whakapai ake, te taipitopito, me te mohio te mea nui rawa atu hei akiaki i te hangahanga teitei o Haina ki te whai hua me te penapena pūngao.
