[size=156%]•1) conduction, where the cow conducts heat to a cooler surface 傳導—— 奶牛傳導熱量到一個較冷的表面
[size=156%]•
2) convection, where thermal currents leave the cow’s body
[size=200%]•對流, 熱氣流離開奶牛的身體
[size=156%]•3)radiation, where the cow radiates heat to a cooler environment, such as the cool night sky
[size=156%]•輻射——熱量到較冷環境如晚上涼爽,
[size=156%]•4)evaporation, where moisture is evaporated from the body surface (sweating) and lungs (panting).
[size=156%]•蒸發——水分從身體表面 (出汗) 和肺臟被蒸發的地方.(喘息)
