Kamano pakeng tsa mocheso oa mocheso oa thepa ea ho pata ke λ=k/(ρ×c), moo k e emelang conductivity ea mocheso ea thepa, ρ e emela ho teteana, 'me c e emela mocheso o itseng.
1. Khopolo ea conductivity ea mocheso
Ka thepa ea ho kenya letsoho, mocheso oa mocheso o bolela bokhoni ba mocheso ka sebaka sa yuniti ho thepa ho feta thepa ka nako ea yuniti, ke hore, lebelo la ho fetisa mocheso. Hangata e bontšoa ke phallo ea mocheso sebakeng sa yuniti ka nako ea yuniti ha phapang ea mocheso e le 1K, 'me yuniti ke W/(m·K). Boholo ba mocheso oa mocheso o itšetlehile ka conductivity ea mocheso le phapang ea mocheso oa thepa.
2. Mokhoa oa ho bala oa conductivity ea mocheso
The conductivity ea mocheso oa thepa ea ho kenya letsoho e amana le boima, mocheso o khethehileng le mocheso oa mocheso oa thepa, 'me kamano pakeng tsa bona ke: λ=k/(ρ×c).
Har'a bona, k e emela conductivity ea mocheso oa thepa, yuniti ke W/(m·K); ρ e emetse density, yuniti ke kg/m³; c e emetse mocheso o itseng, yuniti ke J/(kg·K). Foromo ena e re bolella hore haeba re batla ho fokotsa mocheso oa mocheso oa thepa ea ho pata, re lokela ho fokotsa boima ba 'mele, matla a khethehileng a mocheso le mocheso oa mocheso oa thepa.
3. Lintlha tse amang conductivity ea mocheso
Thermal conductivity ea thepa ea ho kenya letsoho e angoa ke lintlha tse ngata, tse kang mocheso, thepa ea mohaho oa thepa (e kang sebopeho sa kristale), lik'hemik'hale tsa thepa, ho sebelisana ha thepa, joalo-joalo. , porosity le likarolo tse ling tsa thepa ea ho kenya letsoho li tla boela li ama conductivity ea mocheso.
