Thermal conductivity ye zvidhinha zvinopesana (thermal conductivity)

The thermal conductivity (thermal conductivity) yezvidhinha zvinoramba, ndiko kuti, kukwanisa kwayo kuendesa kupisa, kunowanzoratidzwa maererano nekupisa kwekushisa. Kupisa (Thermal conductivity) zvinoreva kuwanda kwekupisa kunopfuudzwa nenzvimbo yeyuniti muchikamu chenguva uye tembiricha yeyuniti mukufambiswa kwesimba. The thermal conductivity yezvinhu zvakasiyana zvinowanzosiyana zvakanyanya. Patembiricha yemumba, kupisa kwekupisa kwezvidhinha zvakasiyana-siyana zvinoramba kuchikwira kunogona kubva pazvikamu zvishoma kubva muzana kusvika kumakumi akati wandei (w/(m·℃)), uye musiyano uripo pakati pekukosha kwepamusoro uye kukosha kwakaderera kunosvika kane chiuru. Sezvo tembiricha inowedzera, iyo yekupisa conductivity mutsauko weakasiyana-siyana zvidhinha zvinoramba zvichiderera, asi mutsauko uchiri wakakura. Semuyenzaniso, pa1000℃, thermal conductivity of lightweight silica is only about 0.35W/(m·℃); recrystallized silicon carbide zvigadzirwa zvinenge 17.5W/(m·℃); graphite inogona kukwira se35W/(m·℃) .
