Buyini ubudlelwano phakathi kokuvuselelwa okushisayo nobuningi, ukushisa okuthile nokuvuselelwa okusebenzayo kwezinto ezibonakalayo?

Ubudlelwano phakathi kokuvuselelwa okushisayo kwezinto zokufakwa kwe-infation yi-= k / (

1. Umqondo wokuvuselelwa okushisayo
Ezintweni zokufakwa kwezinto zokungena, ukuqina okushisayo kubhekisele emandleni okushisa endaweni ngayinye yezinto ezibonakalayo ezisetshenziselwa ukudlula ngesikhathi ngeyunithi ngayinye yesikhathi, okungukuthi, izinga lokudlulisa ukushisa. Imvamisa kuvezwa ukugeleza kokushisa kwendawo ngayinye yeyunithi ngayinye isikhathi lapho umehluko wokushisa u-1k, futhi iyunithi yi-W / (m · k). Ubukhulu bokushisa buncike ekuvuselweni okushisayo kanye nokwehluka kokushisa okuqukethwe.

2. Ifomula yokubala yokuvuselelwa okushisayo
Ukuvuselelwa kwe-thermal kwezinto zokufakelwa kuhlobene nobuningi, ukushisa okuthile nokuvuselelwa okusebenzayo kokuqukethwe, nobudlelwano phakathi kwabo:
Phakathi kwazo, K kumelela ukuqina okushisayo kwezinto ezibonakalayo, iyunithi yi-W / (m · k); ρ umele ubuntu, iyunithi yi-kg / m³; I-C imele ukushisa okuthile, iyunithi ngu-J / (kg · k). Le fomula isitshela ukuthi uma sifuna ukunciphisa ukuthuthuka okushisayo kwezinto zokufakelwa, kudingeka sinciphise ubungako, umthamo othize wokushisa kanye nokuvuselelwa okushisayo kwezinto ezibonakalayo.

3. Izici ezithinta ukuqhutshwa okushisayo
Ukuvuselelwa kwe-thermal kwezinto zokufakelwa kwezinto zokufaka kuthintwa yizinto eziningi, njengokushisa, izakhiwo ezakhiwo ezibonakalayo (njenge-crystal isakhiwo), ukwakheka kwamakhemikhali kokuqukethwe, njll. Ngaphezu kwalokho, okuqukethwe kwamanzi , i-polosioty namanye amapharamitha wezinto zokufakelwa futhi azothinta nokuvuselelwa okushisayo.
