He 60% te nui o te kaha e ngaro ana i roto i nga whare a Windows.I te wera o te rangi, ka whakamahana nga matapihi mai i waho, ka puta te hiko waiariki ki roto i te whare.I te makariri o waho, ka wera nga matapihi o roto, ka puta te wera ki te taiao o waho.Ko tenei tukanga e kiia ana ko te whakamahana rauropi.Ko te tikanga karekau nga matapihi e whai hua ki te pupuri i te whare kia mahana, kia makariri ranei.
Ka taea pea te hanga i tetahi karaihe ka taea te whakaka, te whakaweto ranei i tenei awe whakamatao i a ia ano i runga i tona pāmahana?Ko te whakautu he ae.
Ko te ture Wiedemann-Franz e kii ana ko te pai ake o te hiko o te taonga, ko te pai ake o te werawera.Heoi ano, he mea kee te vanadium dioxide, e kore e tau ki tenei ture.
I tapirihia e nga kairangahau he papa angiangi o te vanadium dioxide, he puhui ka huri mai i te insulator ki te kaikawe i te 68°C, ki tetahi taha o te karaihe.Vanadium dioxide (VO2)he rauemi whai hua me nga ahuatanga whakawhiti wahanga waiariki.Ka taea te huri i te ahua o te ahua i waenga i te kaitao me te whakarewa.Ka noho hei kaitao i te pāmahana rūma me te kaikawe whakarewa i te pāmahana i runga ake i te 68°C.Ko te mea tenei na te mea ka taea te whakarereke i tana hanganga ngota mai i te hanganga karaihe pāmahana rūma ki te hanganga whakarewa i te pāmahana i runga ake i te 68 ° C, ka puta te whakawhitinga i roto i te iti iho i te 1 nanosecond, he painga mo nga tono hiko.Ko nga rangahau e pa ana kua whakapono te tini o nga tangata ka noho pea te vanadium dioxide hei rauemi hurihuri mo te umanga hiko a meake nei.
Ko nga Kairangahau o te whare wananga o Switzerland i piki ake te mahana whakawhiti o te vanadium dioxide ki runga ake i te 100°C ma te taapiri i te germanium, he mea whakarewa onge, ki te kiriata vanadium dioxide.Kua puta kee i roto i nga tono RF, ma te whakamahi i te vanadium dioxide me te hangarau huringa-waahanga ki te hanga i nga whiriwhiringa tere-iti, ka taea te whakarite mo te wa tuatahi.Ko tenei momo tātari hou he tino pai mo te awhe auau e whakamahia ana e nga punaha korero mokowhiti.
I tua atu, ko nga ahuatanga o te vanadium dioxide, penei i te parenga me te whakawhiti infrared, ka tino rerekee i te wa o te huringa.Heoi, he maha nga tono o te VO2 e hiahia ana kia tata te pāmahana ki te taha o te pāmahana rūma, penei i: nga matapihi atamai, nga kaitirotiro infrared, me etahi atu, ka taea e te doping te whakaiti i te pāmahana whakawhiti waahanga.Ka taea e te Doping huānga tungsten i roto i te kiriata VO2 te whakaiti i te pāmahana whakawhiti wahanga o te kiriata ki te huri noa i te pāmahana rūma, na reira he whanui te tono a te VO2-doped tungsten.
I kitea e nga miihini a Hongwu Nano ka taea te whakarereke i te pāmahana whakawhiti o te vanadium dioxide ma te doping, te ahotea, te rahi o te witi, me etahi atu.Ko te doping tungsten e kiia ana ko te tikanga doping tino whai hua me te whakamahia whanui hei whakatika i te pāmahana whakawhiti wahanga.Ka taea e te Doping 1% tungsten te whakaiti i te pāmahana whakawhiti wahanga o nga kiriata vanadium dioxide ma te 24 °C.
Ko nga korero mo te nano-vanadium dioxide-waa-parakore me te tungsten-doped vanadium dioxide ka taea e ta taatau kamupene te tuku mai i nga kararehe e whai ake nei:
1. Nano vanadium hauhā paura, wetekina, wāhanga parakore, wāhanga pāmahana whakawhiti he 68 ℃
2. Vanadium dioxide doped with 1% tungsten (W1%-VO2), the phase transition temperature is 43℃
3. Vanadium dioxide doped with 1.5% tungsten (W1.5% -VO2), the phase transition temperature is 32℃
4. Vanadium dioxide doped with 2% tungsten (W2%-VO2), the phase transition temperature is 25℃
5. Vanadium dioxide doped with 2% tungsten (W2% -VO2), the phase transition temperature is 20℃
Ma te titiro whakamua ki nga wa e heke mai nei, ka taea te whakauru i enei matapihi maamaa me te vanadium dioxide tungsten-doped puta noa i te ao me te mahi i nga tau katoa.
