Hukama huri pakati pekupisa kwekupisa kwechinhu chekudzivirira ndi λ=k/(ρ×c), apo k inomiririra kudziya kwekupisa kwezvinhu, ρ inomiririra density, uye c inomiririra chaiyo kupisa.
1. Pfungwa yekupisa conductivity
Muchigadzirwa chekudzivirira, thermal conductivity inoreva kukwanisa kwekupisa pachikamu chechikamu muchinhu kuti chipfuure nepakati pechinhu panguva yeyuniti, kureva, mwero wekutamisa kupisa. Inowanzo kuratidzwa nekuyerera kwekupisa pachikamu chechikamu panguva imwe chete kana musiyano wetembiricha uri 1K, uye unit iri W/(m·K). Hukuru hwekupisa conduction hunoenderana neiyo thermal conductivity uye kusiyana kwekushisa kwezvinhu.
2. The calculation formula ye thermal conductivity
Iyo yekupisa conductivity yemidziyo yekudzivirira inobatana nedensity, chaiyo kupisa uye kupisa conductivity yezvinhu, uye hukama pakati pavo ndeichi: λ=k/(ρ×c).
Pakati pavo, k inomiririra thermal conductivity yezvinhu, iyo unit ndeye W/(m·K); ρ inomiririra density, chikwata chiri kg/m³; c inomiririra kupisa chaiko, unit iJ/(kg·K). Iyi fomula inotitaurira kuti kana tichida kudzikisa kupisa kwekushisa kwechinhu chekudzivirira, isu tinofanirwa kudzikisa density, chaiyo yekupisa simba uye yekupisa conductivity yezvinhu.
3. Zvinhu zvinokanganisa conductivity yekushisa
Kupisa kwekushisa kwezvinhu zvekudzivirira kunokonzerwa nezvinhu zvakawanda, zvakadai sekushisa, maitiro ekugadzirisa zvinhu (zvakadai sekristal structure), kemikari yezvigadzirwa, kupindirana kwezvinhu, nezvimwewo. , porosity uye mamwe maparameter ezvinyorwa zvekudzivirira zvichakanganisawo kupisa kwekushisa.
