In order to ensure the reasonable modeling method for thermodynamics model, by adopting these four kinds of models and the reference model, the typical thermodynamics characteristic in drum-the dynamic process of"false level"were dynamically simulated, the results of simulation indicate: The modeling method of considering the changing rates of pressure and volume simultaneously is more reasonable, it's simulation result can be consistent with the result of the reference model, and the numeric error is within±5%, so, this method can be used to build thermodynamics model of drum level.

为确定合适的热力学模型建模方法，采用这四种模型和参考模型，对汽包中典型的热力学性质-"虚假水位"现象的动态过程进行了动态仿真，结果表明：同时考虑汽包体积变化率和压力变化率的建模方法，其动态仿真结果完全可以正确地跟踪参考模型的仿真结果，并且数值误差在5%以内，故该建模方法可以用来建立汽包水位热力学模型。
