Amagrafu awuphawu lohlelo ezindaweni eziningi.
Imodeli yezinto zangempela.
Imibuthano ama-vertices, imigqa ngama-graph arcs (ukuxhumana).
Uma kunenombolo eduze kwe-arc, ibanga eliphakathi kwamaphoyinti kumephu noma izindleko eshadini le-Gantt.
Kugesi kanye ne-electronics, ama-vertices ayizingxenye namamojula, imigqa ingabaqhubi.
Kuma-hydraulics, ama-boilers, ama-boilers, okokufakwayo, ama-radiator namapayipi.
Imephu ikhombisa amadolobha nemigwaqo.
Kusuka enkingeni yezibalo zesikole:
Ibhasi lisuka endaweni A liya endaweni B. Ibanga phakathi kwamaphoyinti li-30 km.
Kuthiwani uma ibanga lingu-0?
Yehlisa ibanga ukusuka ophahleni ukuya phansi libe ziro. Indlu enezitezi ezimbili iphenduka i-dugout.
Sinciphisa ibanga ukusuka ku-boiler kuya ku-radiator (ukunciphisa ubude bamapayipi) - sithola isitofu saseRussia.
Njengoba kungenzeka uqagele, ubuchwepheshe busebenza ngezindlela zombili.
Unganciphisa ube uziro noma ukhuphuke uye kokungapheli.
Ukunciphisa ubude bamakholi kagesi kwaholela ekudalweni kwama-microcircuits.
Ubude, ubude nobubanzi izilinganiso zejometri. Izilinganiso zomhlaba wangempela (obonakalayo).
Izilinganiso nazo zingabonakala zingabonakali:
- Temperature
- Isikhathi
- Isisindo
- Ubuningi
- I-Thermal conductivity
- Ukuqhuba kagesi
- Amandla
- Ubugebengu
- Isivinini
- Ukusheshisa
- Amandla
njll.
- ikhono lemizimba ebonakalayo lokuqhuba amandla (ukushisa) ukusuka ezingxenyeni ezishisayo kakhulu kuya ezingxenyeni ezishisayo zomzimba ngokusebenzisa ukunyakaza okungahambi kahle kwezinhlayiya zomzimba (ama-athomu, ama-molecule, ama-electron, njll.).
Indlela yokunciphisa ukuqhutshwa kwe-thermal ku-zero?
Kulungile.
Yehlisa inani lama-athomu, ama-molecule nama-electron. Lokho kuwukwenza i-vacuum.
Ubuchwepheshe obufanayo sebukhona kakade futhi buyathengiswa. Kubizwa nge-screen-vacuum thermal insulation. Amaphaneli ane-thermal conductivity alingana no-0,004-0,006 W/m*K.
Uma kuqhathaniswa, lokhu kungaphansi izikhathi ezingu-10 kunovolo wamaminerali futhi izikhathi ezingu-50 ngaphansi kwezitini.
Ngenxa yalokho, ubukhulu bezindonga bungancishiswa izikhathi eziningi.
Futhi uma unciphisa isisindo sibe zero ...
Kwezinye izindaba, ngeke nginiphuce injabulo yezinto ezintsha ezitholakele.
Ukusungulwa okujabulisayo!
