根据能量守恒定律，各项能量之间的平衡关系一般可表示为According to the law of conservation of energy, the equilibrium relationship between various energies can generally be expressed as： 当进入系统的能量 - 离开系统的能量=系统储存能量的变化 When the energy goes into the system - the energy goes out of the system = the change in the energy stored in the system.
