Iigrafu luphawu lwesikim kwiindawo ezininzi.
Imodeli yezinto zokwenyani.
Izangqa ziyi-vertices, imigca i-graph arcs (uqhagamshelwano).
Ukuba kukho inombolo ecaleni kwe-arc, ngumgama phakathi kwamanqaku kwimephu okanye iindleko kwitshathi yeGantt.
Kumbane kunye ne-electronics, ii-vertices ziyinxalenye kunye neemodyuli, imigca ngabaqhubi.
Kwi-hydraulics, iibhoyili, iibhoyili, izixhobo, ii-radiator kunye neepayipi.
Imephu ibonisa izixeko kunye neendlela.
Ukusuka kwingxaki yezibalo yesikolo:
Ibhasi iphuma kwindawo A ukuya kwindawo B. Umgama phakathi kwamanqaku yi-30 km.
Ukuba umgama ngu-0?
Sinciphisa umgama ukusuka kwi-roof ridge ukuya emhlabeni ukuya kwi-zero. Indlu enemigangatho emibini ijika ibe ngumhadi.
Sinciphisa umgama ukusuka kwibhoyili ukuya kwi-radiator (sinciphisa ubude beepayipi) - sifumana isitofu saseRashiya.
Njengoko usenokuba uqikelele, itekhnoloji isebenza kumacala omabini.
Ungayinciphisa ibe ngu-zero okanye uyinyuse ibe yi-infinity.
Ukunciphisa ubude babaqhubi bombane kwakhokelela ekudalweni kwee-microcircuits.
Ubude, ubude kunye nobubanzi yimilinganiselo yejometri. Imilinganiselo yelizwe lokwenyani (elibonakalayo).
Imilinganiselo inokuba yinto ecacileyo:
- Π’Π΅ΠΌΠΏΠ΅ΡΠ°ΡΡΡΠ°
- Ixesha
- U bunzima
- U buninzi
- Ukuqhuba ukushisa
- Ukuqhuba kombane
- Ukuqina
- Uqhekeko
- Ukukhawuleza
- Ukukhawulezisa
- Amandla
njl.
- ukukwazi kwemizimba yezinto eziphathekayo ukuqhuba amandla (ubushushu) ukusuka kwiindawo ezishushu ngakumbi zomzimba ukuya kwiindawo ezishushu ezincinci zomzimba ngokusebenzisa intshukumo yesiphithiphithi samasuntswana omzimba (i-athomu, iimolekyuli, ii-electron, njl.).
Indlela yokunciphisa i-thermal conductivity ukuya kwi-zero?
Kunene.
Ukunciphisa inani le-athomu, iimolekyuli kunye nee-electron. Oko kukuthi, yenza ivacuum.
Ubuchwephesha obufanayo sele bukhona kwaye buyathengiswa. Ibizwa ngokuba yiscreen-vacuum thermal insulation. Iipaneli ezine-thermal conductivity zilingana no-0,004-0,006 W/m*K.
Ukuthelekisa, oku ngamaxesha angama-10 ngaphantsi koboya bamaminerali kunye namaxesha angama-50 ngaphantsi kwezitena.
Ngenxa yoko, ubukhulu beendonga bunokuncitshiswa ngamaxesha amaninzi.
Kwaye ukuba unciphisa ubunzima ukuya kwi-zero ...
Nangona kunjalo, andiyi kukuhlutha uvuyo lwezinto ezintsha ezifunyenweyo.
Iimveliso ezimnandi!
