让灵敏的仪器远离热的位置(例如机架的顶部)，并在进行测量之前使整个系统达到热稳定状态。
Keep sensitive instruments away from hot locations (such as the top of a rack) and allow the complete system to achieve thermal stability before making measurements.
铁单质是固态，这是他在室温和常压下，最稳定的状态，然后我们，可以算出生成热，现在这个。
Iron as an element is a solid. That's it's most stable state at room temperature and pressure, right, and so on. And then we can figure out heats of formation.
