the fundamental principle of physics that the total energy of an isolated system is constant despite internal changes
双语例句
用作名词 (n.)
This sweeping generalization is the law of conservation of energy. 这一透彻的概括就是能量守恒定律。
If energy were to flow spontaneously from a block of ice to a surrounding volume of water,this could accord with energy conservation completely. 如果能量自发地从冰块传到周围大片水域的话，这完全符合能量守恒定律。
