Lub kiv puag ncig muaj
Qhov kev lag luam tshwm sim thiab dav siv ntawm cov tshuab hluav taws xob tau txhawb nqa lub tshuab hluav taws xob ntawm lwm qhov kev lag luam, uas tau coj mus rau kev hloov kho kom zoo hauv kev siv tshuab thev naus laus zis. Hauv kev lag luam, nws tau ua rau txoj kev loj hlob ntawm lub tshuab kev tsim kev lag luam, kev lag luam steel, thiab kev thauj mus los, thiab pib tsim kev ua tiav ntawm kev lag luam thev naus laus zis; hauv kev tshawb fawb science, nws txhawb nqa kev tsim cov thermodynamic txoj kev xav. Lub kiv puag ncig kev lag luam yog ib qho kev hloov hauv zej tsoom ntawm qhov thev naus laus zis thev naus laus zis. Hauv qhov kev hloov no, txuj tshawb fawb thiab thev naus laus zis tau ua lub luag haujlwm tseem ceeb, ua rau muaj kev nce qib ntau hauv kev tsim khoom hauv zej zog. Nyob rau thawj thawj zaug, kev ua tau zoo ntawm kev tshawb fawb thiab thev naus laus zis tau raug tsom.
