Zero size element

Zero size element

Graphs yog ib tug schematic notation nyob rau hauv ntau qhov chaw.
Qauv ntawm cov khoom tiag.
Cov voj voog yog vertices, kab yog graph arcs (kev sib txuas).
Yog tias muaj tus lej nyob ib sab ntawm lub arc, nws yog qhov kev ncua deb ntawm cov ntsiab lus ntawm daim ntawv qhia lossis tus nqi ntawm daim ntawv Gantt.

Nyob rau hauv hluav taws xob thiab hluav taws xob, vertices yog qhov chaw thiab modules, kab yog conductors.
Hauv hydraulics, boilers, boilers, fittings, radiators thiab kav.
Daim ntawv qhia qhia cov nroog thiab txoj kev.

Los ntawm lub tsev kawm ntawv teeb meem lej:

Lub tsheb npav tawm ntawm point A mus rau point B. Qhov kev ncua deb ntawm cov ntsiab lus yog 30 km.

Yuav ua li cas yog qhov kev ncua deb yog 0?

Peb txo qhov kev ncua deb ntawm lub ru tsev ridge mus rau hauv av mus rau xoom. Lub tsev ob-storey hloov mus rau hauv ib tug dugout.

Zero size element
Peb txo qhov kev ncua deb ntawm lub boiler mus rau lub radiator (peb txo qhov ntev ntawm cov kav dej) - peb tau txais ib tug Lavxias teb sab qhov cub.
Raws li koj tau twv, thev naus laus zis ua haujlwm hauv ob qho tib si.

Koj tuaj yeem txo nws mus rau xoom lossis nce mus rau infinity.

Zero size element

Txo qhov ntev ntawm cov hluav taws xob conductors coj mus rau kev tsim cov microcircuits.

Ntev, qhov siab thiab dav yog qhov ntsuas geometric. Kev ntsuas ntawm lub ntiaj teb tiag (pom).
Kev ntsuas tuaj yeem ua tiav ntau yam:

  • Π’Π΅ΠΌΠΏΠ΅Ρ€Π°Ρ‚ΡƒΡ€Π°
  • ВрСмя
  • Nyhav
  • Kev ceev
  • Thermal conductivity
  • Hluav taws xob conductivity
  • Zog
  • fragility
  • Ceev
  • Acceleration
  • Zog

lwm.

Thermal conductivity - lub peev xwm ntawm cov khoom siv lub cev los ua lub zog (tshav kub) los ntawm ntau qhov chaw ntawm lub cev mus rau qhov tsis tshua muaj cua sov ntawm lub cev los ntawm kev tsis sib haum xeeb ntawm lub cev (atoms, molecules, electrons, thiab lwm yam).

Yuav ua li cas txo thermal conductivity rau xoom?

Txoj cai.

Txo tus naj npawb ntawm atoms, molecules thiab electrons. Ntawd yog, tsim lub tshuab nqus tsev.
Cov tshuab zoo sib xws twb muaj thiab raug muag. Nws yog hu ua screen-vacuum thermal rwb thaiv tsev. Panels nrog thermal conductivity sib npaug rau 0,004-0,006 W / m * K.
Rau kev sib piv, qhov no yog 10 lub sij hawm tsawg tshaj li cov ntxhia wool thiab 50 lub sij hawm tsawg dua cib.
Yog li ntawd, lub thickness ntawm phab ntsa tuaj yeem raug txo los ntawm ntau zaus.

Thiab yog tias koj txo qhov loj rau xoom ...

Txawm li cas los xij, kuv yuav tsis tso koj ntawm kev xyiv fab ntawm kev tshawb pom tshiab.

Zoo siab inventions!
