But we've defined the enthalpy of those elements in their stable state at room temperature and pressure as zero, right?
但我们已经定义了这些，元素处于它们室温和常压下，最稳定的状态时的焓为零，对吧？
What we define as zero is the enthalpy of every element in its natural state at room temperature and ambient pressure.
我们将零点定义为每种元素，在室温和正常大气压下，在其自然状态下的焓。
What we define as zero is the enthalpy of every element in its natural state at room temperature and ambient pressure.
