Size zero element

Ma graph ndi zolemba zamakonzedwe m'malo ambiri.
Chitsanzo cha zinthu zenizeni.
Zozungulira ndi vertices, mizere ndi ma graph arcs (zolumikizira).
Ngati pali nambala pafupi ndi arc, ndiye mtunda pakati pa mfundo pamapu kapena mtengo wa tchati cha Gantt.

Mumagetsi ndi zamagetsi, ma vertices ndi magawo ndi ma modules, mizere ndi ma conductor.
Mu ma hydraulics, boilers, boilers, zovekera, ma radiator ndi mapaipi.
Mapu akuwonetsa mizinda ndi misewu.

Kuchokera ku vuto la masamu akusukulu:

Basi inyamuka kuchoka pa point A kupita ku point B. Mtunda pakati pa mfundo ndi 30 km.

Bwanji ngati mtunda uli 0?


Timachepetsa mtunda kuchokera padenga la denga mpaka pansi mpaka zero. Nyumba ya nsanjika ziwiri imasanduka mbiya.

Timachepetsa mtunda kuchokera ku boiler kupita ku radiator (timafupikitsa kutalika kwa mapaipi) - timapeza chitofu cha Russia.
Monga momwe mungaganizire, ukadaulo umagwira ntchito mbali zonse ziwiri.

Mutha kuzichepetsa mpaka ziro kapena kuziwonjezera mpaka zopanda malire.

Kuchepetsa kutalika kwa oyendetsa magetsi kunapangitsa kuti pakhale ma microcircuits.

Utali, kutalika ndi m'lifupi ndi miyeso ya geometric. Miyeso ya dziko lenileni (lowoneka).
Miyeso imatha kukhala yodziwika bwino:

• Температура
• Nthawi
• Kulemera
• Kusakanikirana
• Thermal conductivity
• Magetsi conductivity
• Kukhazikika
• Kusayenda
• Kuthamanga
• Kupititsa patsogolo
• Mphamvu

ndi zina.

Thermal conductivity - Kuthekera kwa matupi akuthupi kuchititsa mphamvu (kutentha) kuchokera kumadera otentha kwambiri a thupi kupita kumadera osatenthedwa kwambiri a thupi kudzera mukuyenda kwachisokonezo kwa tinthu tating'onoting'ono ta thupi (maatomu, mamolekyu, ma elekitironi, etc.).

Kodi mungachepetse bwanji matenthedwe matenthedwe kukhala zero?

Kulondola.

Chepetsani kuchuluka kwa ma atomu, mamolekyu ndi ma elekitironi. Ndiko kuti, pangani vacuum.
Ukadaulo wofananawo ulipo kale ndipo ukugulitsidwa. Amatchedwa screen vacuum thermal insulation. Mapanelo okhala ndi matenthedwe matenthedwe ofanana ndi 0,004-0,006 W/m*K.
Poyerekeza, izi ndizocheperapo ka 10 kuposa ubweya wa mchere komanso nthawi 50 kuposa njerwa.
Zotsatira zake, makulidwe a makoma amatha kuchepetsedwa nthawi zambiri.

Ndipo ngati muchepetse misa mpaka zero ...

Komabe, sindidzakulepheretsani kusangalala ndi zinthu zatsopano.

Zosangalatsa zopanga!
